Best overall weight loss protein powder: Transparent Labs 100% Grass-Fed Whey Protein Isolate

Why we like Transparent Labs Whey Protein Isolate as best overall

Transparent Labs 100% Grass-Fed Whey Protein Isolate packs in protein, comes in a variety of flavors and tastes great. That’s why it’s at the top of our list for best overall protein powder for weight loss.

Transparent Labs is known for creating high-quality supplements using natural ingredients. The whey protein isolate comes from grass-fed cattle raised without growth hormones or antibiotics. The supplement is also free of artificial sweeteners, fillers, food dyes, preservatives, and gluten.

Transparent Labs uses whey protein isolate as its main source of protein. Whey protein isolate is the “gold standard” protein in protein powders. It’s processed to have more protein and less carbs and fat with a high leucine content, an amino acid that starts protein synthesis in the muscles. ( 2 )

The whey protein isolate also makes it an effective protein powder for weight loss. When you lose weight, you don’t just lose fat, you lose muscle too. Muscle loss lowers metabolism, so you need to eat less to keep losing weight.

Supplementing with whey protein isolate may help you lose fat and keep muscle, preventing a dip in your metabolism. ( 3 ) The best results are achieved by Combining the supplement with a weight-training program.

If you struggle to muster up the energy to work out, you may want to consider the best pre-workouts for a boost.

Whey protein also keeps hunger at bay. Research shows that animal-based protein is more filling than a carbohydrate-based snack that has the same number of calories. It seems to reduce appetite by activating the release of hunger-controlling chemicals. ( 4 )

Adding protein powder to your usual diet isn’t going to help you drop unwanted pounds. But it may make it easier for you to create and maintain the calorie deficit you need to lose weight by helping with hunger and changes in metabolism.

When choosing Transparent Labs protein powder for weight loss, you have 15 flavor options, including traditional flavors like chocolate and vanilla and fun flavors like peppermint hot chocolate and chocolate peanut butter. One of our product testers said, “This is definitely one of the best protein powders I’ve ever had, and I’m not just saying that.”

The powder mixes well with water, milk, and other liquids. There is no need for a blender with this ultra-fine protein powder. Use a shaker cup with a wire whisk to dissolve the powder and prevent clumps. You can also add Transparent Labs whey protein to yogurt or oatmeal or mix it in pancake batter.

At $2.00 a serving, Transparent Labs protein powder is a good value. But it has a higher price point than some of the other supplements on our list. It’s also not suitable for people on a vegan or dairy-free diet. Some people may also notice an aftertaste from stevia, the low-calorie, all-natural sweetener.

What customers are saying

Most Amazon shoppers have good things to say about Transparent Labs Whey Protein Isolate protein powder. They love the taste, quality, and nutrition.

Evan says, “It tastes good and produces good results. I’m on my second container and about to buy a third.”

Kaiser is a verified buyer and not a fan of the protein powder, posting a critical review. “I recently bought the vanilla and peanut butter and it was too sweet, and the taste seemed off.”

Best affordable protein powder for weight loss: Sports Research Whey Protein Isolate

Why we like Sports Research Whey Protein Isolate as best affordable

Protein powders can put a dent in your budget. We like Sports Research Whey Protein Isolate as the best affordable protein powder for weight loss because it’s a high-quality supplement without the high price.

The smaller 2.1-pound bag costs $1.46 a serving, with 26 servings per bag. If you have the space and flexibility in your budget, buying the larger 5.1-pound bag of protein powder reduces the price to $1.09 a serving, with 63 servings.

Despite the low price, Sports Research Whey Protein Isolate is made with quality ingredients. Whey protein isolate is the main ingredient, providing 25 grams of protein. The supplement contains an additional 1,000 milligrams of leucine and supplies 6.9 grams of BCAAs.

Leucine is an essential amino acid and one of the BCAAs. (3, 27) It also drives muscle protein synthesis, and taking higher levels of leucine with protein can optimize muscle protein production. (3) A recent small study found that supplementing with leucine on a calorie-restricted diet prevented significant losses in muscle tissue in men. ( 32 ) We don’t recommend adding leucine supplements for weight loss since research is in the very early stages.

One serving of Sports Research Whey Protein Isolate has 140 to 150 calories, 2 to 4 grams of carbs, and 3.5 t0 4 grams of fat. The supplement is fortified with vitamin D, meeting 100% of daily needs. It’s also a good source of calcium meeting 11% of needs.

The whey protein powder uses stevia in their Vanilla flavor (the Dutch Chocolate use sucralose) as a low-calorie, natural sweetener and has MCT oil. Stevia can affect taste, and MCT oil may cause side effects like abdominal pain or diarrhea. (13) This protein supplement isn’t suitable for people on a vegan or dairy-free diet. The Sports Research supplement also contains coconut, so it isn’t safe for people with tree nut allergies.

You can shake, blend, or bake your Sports Research Whey Protein Isolate. It mixes well without clumping. The supplement is third-party tested but only for banned substances, according to the official website.

The price and protein quality give this protein powder high marks, but flavor options are limited to chocolate and vanilla.

What customers are saying

Amazon reviewers have a lot of good things to say about Sports Research Whey Protein Isolate. They like the taste, ingredients, and the great value for the 5.1-pound bag. Most complaints center around digestive issues like bloating and nausea.

Amazon buyer Callie agrees, noting that it tastes great and mixes easily. However, Callie also writes, “wish it didn’t have the MCT oils and had better macros—but product gives me an upset stomach and major bloating + cramping—wonder if it’s the added fats/MCT.”

Best tasting protein powder for weight loss: Jacked Factory Authentic Iso Cinnamon French Toast

Why we like Jacked Factory Authentic Iso as best tasting

Jacked Factory Authentic Iso is an affordable, high-quality protein powder that helps repair and build muscle after an intense workout. Beyond the benefits of the whey protein isolate, this protein powder for weight loss made our list for its delicious taste. Our testers really liked the Cinnamon French Toast flavor, noting that the taste is pleasant and smooth with the right amount of sweetness.

Jacked Factory Authentic Iso is also one of the least expensive protein powders on our list. Like Transparent Labs, it’s made with grass-fed whey protein isolate, providing high-quality protein and all the amino acids for maintaining and gaining muscle. However, it costs about $0.70 less per serving than Transparent Labs.

If you follow a weight-training program, this protein powder is for you. The whey protein isolate is easy to digest and goes straight to the muscles. Taking whey protein isolate combined with weight training is proven to increase muscle strength and size. ( 6 )

Adding more muscle is beneficial on a weight-loss plan because it is a key player is maximizing your resting metabolism, allowing you to burn calories effectively throughout the day ( 7 ). Moreover, ensuring adequate protein, combined with resistance exercise to maintain and perhaps build some muscle, will enable your best metabolism to help you maintain your healthy weight.

When using protein powder for weight loss, incorporate the supplement into your diet so you stay within your ideal calorie range. Adding protein shakes without modifying your diet may lead to weight gain.

Another thing we liked about Jacked Factory Authentic Iso protein powder is its short list of ingredients. However, unlike some of the other protein powders for weight loss, the Jacked Factory protein supplement has artificial ingredients like sucralose.

Sucralose is an artificial sweetener generally recognized as safe, but some people report bloating and gas when eating or drinking foods sweetened with sucralose. ( 8 ) Jacked Factors also uses stevia to sweeten the protein powder. Stevia is a natural low-calorie sweetener, but it has a bitter aftertaste that may make it harder for you to enjoy the taste of the delicious protein supplement.

Another shortcoming of Jacked Factor Authentic Iso is that it doesn’t have third-party testing for quality and safety. The FDA doesn’t regulate supplements, and it’s up to the manufacturer to make sure their product is safe. ( 9 ) Third-party testing means the ingredients in the bottle match what you read on the label.

Though we loved the flavor of this protein powder, we had to give it a lower rating because of the artificial ingredients and lack of testing.

What customers are saying

Customers who purchase Jacked Factory Authentic Iso give it rave reviews. They like its creamy texture and taste and how well it mixes with water and milk.

Theodore M., a verified Amazon buyer, says, “I love the flavor, but obviously, this is personal preference, as some reviewers do not like it. It is a bit on the sweeter side. I use this protein as an in-between-meal supplement. I am always hungry, especially on gym days, so this is great for me.”

Mag is another verified Amazon purchaser who says the cinnamon French toast flavor is a morning staple. “This is one of the best-tasting proteins I’ve tried, it tastes exactly like French toast.”

Specs

Best casein protein powder for weight loss: Legion Casein+

Why we like Legion Casein+ as best casein

Legion Casein+ is our pick for the best casein protein powder for weight loss because it’s a clean protein powder with 23 to 26 grams of protein and 110 to 140 calories per serving. It also has less than 1 gram of fat and only 3 grams of carbs and is an excellent source of calcium.

Milk protein is 80% casein and 20% whey. ( 10 ) Like whey, casein is a high-quality protein with all the essential amino acids necessary for muscle growth in response to resistance exercise. However, the body digests and absorbs casein more slowly than whey, and why many people prefer whey protein powder over casein immediately after a workout. (10) But casein helps build muscles too, and can help you achieve your body goals.

Casein also helps with weight management by suppressing the appetite. In some studies, it works better at decreasing hunger than whey, but research is mixed. ( 11 ) Many people take casein supplements before bed because it as it supports positive changes in muscle while you sleep, it doesn’t appear to hinder the release and use of fat for energy as you dream away. (11) Its like the best of both worlds when it comes to making positive changes in body composition.

Supplementing with casein protein powder like the one from Legion boosts dietary protein intake and can improve body composition when combined with a muscle-building workout.

Our product testers had mixed reviews for Legion Casein+. One tester said it mixed well but separated after 20 minutes. Another tester said the texture was a normal thickness, but they didn’t like the chalky aftertaste.

Legion Casein+ has a very short ingredient list and no artificial ingredients or added sugar, using stevia to make it sweet. Though a bit pricier than other protein powders, Legion has a subscribe and save program that reduces your cost. They also offer a money-back guarantee.

According to the Legion website, every bottle of Casein+ is analyzed for potency and purity at an accredited lab, directing you to click a link to see the most recent Certificate of Analysis (CoA).

Legion earned a high rating for creating a clean casein protein powder with a small list of ingredients, having third-party testing, and openly sharing the CoA so consumers can check for safety.

What customers are saying

Many Amazon customers say Legion Casein+ is the best casein protein powder available. They say it mixes well and keeps them satiated overnight.

According to verified Amazon purchaser Tyler F., “Taste is very nice and not overly sweet when mixed with water or milk.”

Alex also enjoys this casein powder supplement, saying it ” mixes superbly and doesn’t have that chalky unpleasant texture that some casein does.”

Best ketogenic protein powder for weight loss: Gainful Protein Powder

Why we like Gainful Protein Powder as the best ketogenic

Gainful Protein Powder is unlike any of the other protein powders on our list. With Gainful, you get the mix, match, and modify your protein formula, giving your body exactly what it needs. This includes a ketogenic weight loss option, making the list of the best ketogenic protein powders for weight loss.

The ketogenic diet is a very low-carb, high-fat diet people follow to lose weight. The weight-loss program restricts carbohydrate intake to about 10% of daily calories, or about 20 to 50 grams of carbs a day. ( 12 ) Carbs are the body’s main source of energy, and restricting intake forces the body to burn fat for energy, putting the body into ketosis.

It is also important to get the right amount of protein when following the ketogenic diet. You need enough protein to improve nutrition and variety, but not too much that it pushes you out of ketosis (12). Finding the right macronutrient balance is vital.

Gainful’s ketogenic weight loss formula is a great option for people who need more high-quality protein while following a low-carb, high-fat diet plan. It was created by nutrition and fitness experts and provides 19 grams of protein, 6 grams of fat, and 3 grams of carbs.

The specialized protein formula uses whey protein isolate for protein, keeping carbs low and protein high. It uses medium-chain triglyceride (MCT) oil powder and sunflower lecithin to increase fat. MCT oil is a type of saturated fat that’s easier to absorb than other fats. However, it can have unpleasant side effects like abdominal pain, gas, vomiting, or diarrhea. ( 13 )

The ketogenic protein powder formula is unflavored. Gainful has single-serving flavor boosters you can add to protein shakes. Depending on the flavor, adding a booster to your keto-friendly protein shake increases carbs by 1 to 2 grams.

In addition to customized protein powders, Gainful gives customers free access to registered dietitians for expert guidance on their health journey. However, “free” access to dietitians kind of explains the high price of this protein powder. At $3.21 per serving, Gainful Protein Powder is one of the more expensive choices on our list.

Though we appreciate the use of natural ingredients and access to experts, Gainful lost points since it lacks third-party testing.

What customers are saying

Most Trustpilot reviewers like Gainful Protein Powder. They say it’s easy to mix and doesn’t taste chalky.

Verified buyer Ian G. likes Gainful’s transparency and knowing exactly what’s in the supplement.

Most complaints centered around shipping and subscriptions. Tricia K. was unhappy that shipping took 9 business days, and Kristina P didn’t like that she was charged for a second order when she selected the one-time purchase option.

Specs

Best pea protein powder for weight loss: Nutricost Organic Pea Protein Isolate

Why we like Nutricost Organic Pea Protein Isolate as best pea protein

Nutricost Organic Pea Protein Isolate is a one-ingredient protein powder, earning the spot on our list for best pea protein. One serving provides 20 grams of protein and only 100 calories. It’s also low in fat and carbs and provides 30% of the daily value for iron.

This protein powder is perfect for people who follow a vegan or dairy-free diet. It’s also gluten-free and safe for people with celiac disease or gluten sensitivity.

Peas are a legume naturally rich in protein, fiber, and other nutrients. Manufacturers make pea protein from yellow peas by separating the starch and other nutrients from the protein, creating a protein-rich powder. ( 15 ) Pea protein isolate is further processed, removing most of the carbohydrates to create a powder with a higher concentration of protein.

Pea protein isolate is a plant protein, and you can’t go wrong with eating more plants. According to research, plant proteins offer many benefits like keeping you full, maintaining energy, and lowering cholesterol. ( 14 )

But how can pea protein help with weight loss? Though research is limited, a small study found that pea protein had the same effect on appetite and metabolism as whey protein. ( 15 ) Though more research is needed, pea protein isolate seems to provide similar weight-loss benefits as whey protein, especially when total daily protein needs are met, which are higher for people managing their calories and exercising to lose weight and/or lean out.

Eating more plant proteins also benefits the environment. Nutricost’s plant protein is certified USDA organic and made sustainably without harmful pesticides or fertilizers. ( 16 ) It’s also gluten-free and third-party tested.

At $0.43 a serving, the organic pea protein powder is a great value and the cheapest protein powder on our list. However, Nutricost Organic Pea Protein Isolate only comes unflavored. This might give you more freedom in creating your own flavors, or you may want a protein powder that only needs water or plant milk.

Pea protein powder has a beany smell and bitter flavor that some people find off-putting. Instead of drinking it in a shake, add it to savory dishes like soup, casseroles, and tofu. Nutricost Organic Pea Protein Isolate is a simple, inexpensive, plant-based protein made from organic ingredients, which is why it’s one of the best. However, none of this matters if you don’t like the taste.

What customers are saying

Customers who buy Nutricost Organic Pea Protein Isolate say they like the price, protein quality, and taste.

Donny D., a verified Amazon shopper, says it’s “cheaper than other popular brands with good ingredients.” Donny says the taste isn’t great and recommends blending it with a banana.

Best meal replacement protein powder for weight loss: Ka’Chava All-In-One Nutrition Shake

Why we like Ka’Chava Nutrition Shake as best meal replacement

The makers of Ka’Chava Nutrition Shake designed the meal replacement drink to fit busy lives. It’s a delicious, high-protein, plant-based drink made from all-natural ingredients rich in vitamins, minerals, antioxidants, and essential fatty acids. The multinutrient shake also contains prebiotics and probiotics to support gut health and chia seeds and flaxseeds for fiber and omega-3s.

One serving, two scoops of powder, has 240 calories, 25 grams of protein, 21–25 grams of carbs, and 7–8 grams of fat. It also supplies more than 50% of the daily value for many vitamins and minerals like vitamins A and E, folate, magnesium, zinc, and selenium.

It’s also an excellent source of vitamin B12, a nutrient only found in meat products and difficult to obtain on a vegan diet ( 17 ). One serving of the Ka’Chava nutrition shake is also an excellent source of calcium, iron, and fiber.

The protein in the meal replacement shake comes from a plant-based protein blend consisting of yellow pea protein, organic whole grain brown rice protein, organic sacha inchi (a seed), organic amaranth, and organic quinoa.

Meal replacement shakes are an effective weight-loss tool ( 18 ). They help keep calories in check and relieve the stress of figuring out what to eat.

Though Ka’Chava shakes are an excellent source of essential nutrients, the makers recommend not using them to replace every meal but one or two. Replacing some of your meals with a nutrient-rich shake helps you feel more in control over your eating while giving you an opportunity to create healthy eating habits that lead to long-term weight management. ( 18)

Ka’Chava nutrition shakes come in five flavors: chocolate, vanilla, coconut acai, chai, and matcha. Each bag has 15 servings, so if you’re replacing one meal a day, you may need at least two bags a month.

At $4.67 a serving, Ka’Chava is pricey. But they have a subscribe and save program, lowering the price to $4.00 a serving with a standing monthly order.

The meal replacement weight loss shake is made in a plant that processes wheat, milk, and soy. So this wholesome meal replacement may not work if you’re allergic to any of these foods.

What customers are saying

Customers like the taste, convenience, and nutrition of Ka’Chava but are unsure about the price.

On Amazon, verified buyer Jon S. said it tastes great and mixes well with plant milk but is too expensive.

Not everyone likes the taste of the nutrition shake, however. Crystal C. writes that it’s too thick and has an unpleasant aftertaste.

Specs

Best plant-based protein powder for weight loss: Ritual Essential Protein Daily Shake 18+

Why we like Ritual Essential Protein Shake as best plant-based

Ritual Essential Protein Daily Shake 18+ is a plant-based protein powder that goes the extra mile. We selected Ritual as the best plant-based protein powder for weight loss because of its nutrition profile, added amino acids for muscle growth, and supply chain transparency.

One serving of Ritual Essential Protein has 20 grams of protein, 3 grams of carbs, 2 grams of fat, and 115 calories. They use organic pea protein made from yellow peas and sourced from regenerative farms in their formula. Regenerative farms use farming methods that focus on keeping the soil healthy and diverse. ( 19 )

Ritual Essential Protein Daily Shake 18+ adds L-methionine to the pea protein to complete the amino acid profile. L-methionine is an essential amino acid, so it must come from food. ( 20 ) Plant-based proteins like pea tend to have lower amounts of L-methionine than animal-based proteins. (20) But you can get all the methionine you need by eating a varied diet without meat.

However, by adding L-methionine, Ritual’s pea protein powder provides all the amino acids necessary to repair and build lean muscle. They also add choline, a helper nutrient for L-methionine.

Ritual uses fermented sugar cane and monk fruit, which are both natural low-calorie sweeteners, to create flavor without added sugar, stevia, or sugar alcohol. This helps keep carbs low and minimizes problems like a bitter aftertaste.

Though Ritual Essential Protein is a great protein powder for adults following a vegan or dairy-free diet, It isn’t a good fit for people with tree nut allergies. The powder contains MCT oil from organic coconuts, a tree nut.

Clean ingredients and added nutrients may explain the high price of this protein powder. One serving of the plant-based protein costs $2.67. It also requires more effort to make. Instructions on the website suggest using a shaker bottle or blender to get the best results rather than stirring.

Another downside of the Ritual’s protein powder is that it only comes in one flavor: vanilla.

What customers are saying

People who buy Ritual from Amazon say they like that it’s a plant-based protein powder that provides all the amino acids, but they have trouble with taste and blending.

Another buyer, KC MCG, agrees with Kate, noting it’s the best protein powder they’ve tried.

Nancy G., on the other hand, says the protein powder lacks flavor, is too thick, and was disappointed about the no-refund policy.

Best organic protein powder for weight loss: Ora Organic So Lean & So Clean Plant-Based Superfood Protein

Why we like Ora Organic So Lean & So Clean as best organic

Organic crops have a higher concentration of antioxidants and lower levels of toxic chemicals like heavy metals, fertilizers, and pesticides. ( 21 ) People who eat organic are more health conscious and tend to eat more whole foods. (21)

Though other protein powders on this list include organic ingredients, we selected Ora So Lean & So Clean as the best organic protein powder for weight loss because almost every ingredient is organic.

It’s a plant-based protein powder with a protein blend consisting of pea, rice, and quinoa. So Lean & So Clean also has a superfood and greens blend that provides essential vitamins, minerals, and antioxidants, and an enzyme blend that includes digestive enzymes meant to ease digestion.

The specialized blends in Ora So Lean & So Clean pack in a lot of nutrition. One serving has 21 to 22 grams of protein, 4 to 5 grams of carbohydrates, 2.5 to 3 grams of fat, and 120 to 130 calories. It’s also an excellent source of iron, meeting 33% of the daily value.

Like other protein powders, So Lean & So Clean supports weight loss by controlling hunger and maintaining lean muscle mass. It’s a good choice for people who follow a vegan diet or need to avoid dairy, soy, or gluten.

Unlike most of the other protein powders on our list, the organic plant-based protein isn’t promoted as a post-workout drink. According to the website, you can enjoy So Lean & So Clean any time of the day, making it into a shake or adding it to baked goods.

Though the superfood and greens blend provides a healthy dose of antioxidants, it may be too much. Large doses of antioxidants from supplements may disrupt normal cell function ( 22 ). Most health experts recommend getting antioxidants from food, not supplements. The antioxidants in the So Lean and So Clean are food-based and concentrated.

Furthermore, the enzyme blend may not alleviate digestive concerns like gas and bloating. Unless protected by a special coating, enzyme supplements taken by mouth may not survive the acidic stomach. ( 23 )

At $2.00 a serving, Ora Organic So Lean & So Clean is less expensive than some of the other nutrient-packed plant protein powders, like Ka’Chava and Ritual. However, each bag has 20 servings, so if you use it every day, you may run out sooner than you think.

Though limited to four flavors, they keep it simple with vanilla, chocolate, vanilla chai, and unflavored.

In addition to being certified organic, Ora’s plant-protein powder is third-party tested to check ingredient potency, heavy metal content, microbial contaminants, and pathogens.

What customers are saying

On Amazon, Ora So Lean & So Clean has almost 6,000 reviews and a 4.1 rating. Customers like the quality of the ingredients and the ease of mixing, however not everyone likes the taste.

Verified purchaser Raychel writes, “I’ve been taking it for a few weeks now, and it sits well with my stomach. The taste is delicious VANILLA FLAVOR I mix it with any fruit of my choice.” Other positive reviewers say it mixes well with plant milk and oatmeal.

Many of the critics of So Lean & So Clean dislike the taste or texture. Verified buyer Theresa H. disliked the taste and was also unhappy that, “I can’t get my order refunded since the product is not returnable.”

Best protein snack for weight loss: Promix Protein Puffs

Why we like Promix Protein Puffs as best protein snack

Powder isn’t the only way to get more protein. Promix Protein Puffs are protein pellets and make the list of the best protein snacks for weight loss.

The pellets get their protein from whey protein concentrate and whey protein isolate sourced from grass-fed cattle. Other ingredients include non-GMO tapioca for texture and calcium and sunflower lecithin to prolong shelf-life. ( 24 )

Each scoop of Promix Protein Puffs has 10 grams of protein, 2 grams of carbs, less than 1 gram of fat, and 50 calories. It comes unflavored or chocolate-flavored. The chocolate protein puffs also contain cocoa. Both flavors are soy—and gluten-free and made without gums, fillers, or added sugar.

The tiny protein pellets are great for people who want to add a little protein to their food. They add texture and flavor to yogurt, oatmeal, and smoothie bowls. You can also add unflavored protein pellets to savory foods like soups, casseroles, or grain dishes. People also eat the pellets alone, but the tiny pellets are hard to eat and stick to the teeth.

The pellet form makes this protein supplement unique, but it turns into powder when blended. So, you can add a scoop or two of pellets to a protein shake, smoothie, or water. It also makes a good protein source for blended protein coffee or proffee. The drawback is that you need a blender to use the pellets in a liquid.

The pellets make it easy to add protein to your diet to support your weight and nutrition goals. The whey protein may also curb hunger and cravings.

We also like that the protein puffs are third-party tested for heavy metals, allergens, and other contaminants. The protein pellets’ makers provide details about testing on their website.

Promix Protein Puffs have many positive attributes, earning high ratings from our testers. They’re easy to use, effective, and safe. However, the puffs have very limited flavor options—unflavored and chocolate—and a small serving size.

What customers are saying

More than 1,000 Amazon customers posted reviews of Promix Protein Puffs. Most like its versatility. However, a few find the pellets tasteless and not worth the money.

Verified purchaser Danielle writes, “I honestly love this stuff in my Greek yogurt or protein shake. It adds that crunch that one sometimes wants with low calories and high protein ratio.”

Critics of Promix Protein Puffs say the pellets are tiny and tasteless. Verified purchaser Kelly C. writes that the pellets were chalky, bitter, and sticky.

Best unflavored protein powder for weight loss: Naked Nutrition Grass Fed Whey

Why we like Naked Nutrition Grass Fed Whey as best unflavored

Naked Nutrition Grass Fed Whey takes the top spot for best unflavored protein powder for weight loss with minimal ingredients, including it’s whey protein concentrate.

Whey protein concentrate is a less processed precursor to whey protein isolate. ( 2 ) It has a lower concentration of protein and little more fat and carbohydrates than the isolate.

Whey protein concentrate also retains more lactose. Though tolerance levels differ, many people with lactose intolerance can handle up to 12 grams of lactose a day. ( 5 ) A serving of Naked Nutrition Grass Fed Whey protein has about 3 grams of lactose.

Despite the slight differences in nutrient composition, whey protein concentrate is a high-quality protein with all of the essential amino acids at optimal levels. Studies show that it’s as effective at building muscle as other proteins like chicken and beef. ( 25 ) The important thing to remember is that the protein is the same in whey protein concentrate and isolate, the primary difference is the isolate has even more fat and carbohydrate removed.

According to the Naked Nutrition website, the protein undergoes as little processing as possible so it retains more nutrients like conjugated linoleic acid (CLA)—a polyunsaturated fat found in grass-fed beef and milk products. Naked Nutrition suggests CLA in the protein powder supports fat loss. Though research has shown that CLA may support small changes in body composition, it’s not a magical fat eraser. ( 26 ) Plus the level of CLA applied in research studies is likely not achieved per serving.

Naked Nutrition’s whey protein powder packs in a lot of protein―25 grams per serving. A good protein powder for weight loss should have at least 20 grams per serving. (25) It is important to remember that protein requirements are elevated during caloric imbalance supporting weight loss to retain muscle especially coupled with resistance exercise.

We also like Naked Nutrition Grass Fed Whey protein powder because there are 6 different flavors including an unflavored option, expanding its use. When making a protein shake, use fruits or vegetables to create the flavor profile you like. You can also mix the unflavored protein powder into yogurt or oatmeal or add it to baked goods.

Naked Nutrition whey protein powder is also more affordable than other protein powders, at $1.25 a serving. You can save more by signing up for autoship. You save 20% on your first order—$1.00 a serving—and 10% for every shipment after that—$1.12 a serving.

Following their slogan, “We have nothing to hide,” Naked Nutrition products are third-party tested, giving you the assurance that the supplement contains exactly what it says on the label.

This protein powder has many good qualities and earns a high rating. However, it’s not suitable for people who follow a vegan or dairy-free diet.

What customers are saying

More than 15,000 Amazon shoppers have written reviews for Naked Nutrition Grass Fed Unflavored Whey Protein Powder. Many customers say it’s the best protein powder on the market. They like that it has few ingredients and it’s easy to mix. However, some customers report getting containers that are only half-filled. They also complain that the powder clumps.

Another verified purchaser, Marianne M., says, “No additives at all! Tastes great, blends well, lots of protein.”

Most critical reviews center around servings per container, noting that the container appears half full and weighs less than stated on the label. Verified purchaser, Michael, says the container they received had only half the number of servings.

Best vegan protein powder for weight loss: Vega Sport Protein

Why we like Vega Sport Protein as best vegan

Vega Sport Protein uses a multi-blend plant protein formula that includes pea protein, pumpkin seed protein, organic sunflower seed protein, and alfalfa protein. Using multiple plant proteins improves the amino acid profile of this vegan protein powder , providing all the essential amino acids in sufficient quantities.

Our testers liked Vega Sport Protein, finding it easy to mix. They were also surprised about the taste since it’s a plant-based protein. One tester said it “tastes pretty decent.”

With 30 grams of protein and 5 grams of BCAAs, Vega Sports Protein is our choice for best vegan protein powder for weight loss. BCAAs are essential amino acids, which are most responsible for building and maintaining lean muscle mass. ( 27 ) BCAAs may help improve body composition by preserving muscle and increasing fat loss when part of a weight loss plan, especially when exercise is a tactical component. ( 25 )

The amount and type of protein powder in Vega Sports Protein may support your weight-loss efforts. However, the vegan protein powder is higher in calories, fat, and carbs than other protein powders on this list. One serving has 170–180 calories, 3.5–4 grams of fat, and 5–6 grams of carbohydrates. Like any protein powder you use for weight loss, make the supplement part of your nutrition plan so it meets your needs, not exceeds them.

Vega Sport Protein is low in carbs and sugar-free, making it a vegan keto-friendly protein powder. To improve the fat-to-carb ratio for the keto diet, you may need to add a healthy fat such as avocado or peanut butter.

Research indicates that people who follow a vegan diet are more likely to have low iron stores ( 28 ). Vega Sport Protein provides 30–45% of the daily value of iron in one serving, which is another reason why we like it as the best vegan protein powder.

Vega Sport Protein comes in multiple flavors, including vanilla, chocolate, mocha, berry, and peanut butter. The supplement uses stevia as a sweetener, which can affect taste.

This vegan protein powder is pricey at $3.25 a serving and you only get 19 to 20 servings per container.

Though a great option for people following a vegan diet, Vega Sport Protein is made in a plant that processes common food allergens like milk, soy, peanuts, eggs, tree nuts, and sesame. Vegans with food allergies may need to find an alternative brand.

What customers are saying

With a rating of 4.3, Amazon customers like Vega Sport Protein because it’s vegan, gluten-free, and high in protein. Critics dislike the protein powder’s smell and aftertaste.

Not every reviewer enjoys the vegan protein powder. Verified buyer Jennifer V. writes, “This does not dissolve well. It has a very strong pea protein flavor that repeated on me. It was very hard to drink because the taste is not good and it’s very gritty.”

Best protein shake for weight loss: Optimum Nutrition Gold Standard Ready-to-Drink Protein Shake

Why we like Optimum Nutrition Gold Standard Ready-to-Drink shake as best protein shake

We like Optimum Nutrition Gold Standard Ready-to-Drink shake as the best protein shake because it’s high in protein, low in calories, and convenient. One container provides 24 grams of protein, 3–4 grams of carbohydrates, 3 grams of fat, and 130–140 calories.

The ready-to-drink shake uses a protein blend consisting of milk protein isolate, milk protein concentrate, whey protein concentrate, and calcium caseinate. Milk protein isolate and milk protein concentrate contain a mix of whey and casein, with the isolate having a higher concentration of protein. ( 29 ) Calcium caseinate is a form of casein. (10)

The protein blend provides a mix of whey and casein proteins, so it may curb your appetite and keep you full longer. The mix of proteins also helps maintain, repair, and build lean muscle. (2,4,10)

Another reason Optimum Nutrition Gold Standard Shake made our list of the best protein shakes for weight loss is its vitamin and mineral content. This shake is fortified and provides 20% or more of the daily value for vitamins A, C, D, and E, folate, vitamin B12, calcium, zinc, and selenium.

Eating a balanced diet is the best way to get all the essential nutrients. However, many people struggle to eat an adequate amount of nutrient-dense foods, increasing the risk of nutritional deficiencies. ( 30 ) Food fortification is a practice that adds nutrients to food to prevent deficiencies. (30)

Optimum Nutrition’s protein shake can’t replace healthy food or a balanced diet, but it’s a good way to boost nutrient intake. However, since it’s so low in calories, we don’t recommend using the ready-to-drink protein shake as a meal replacement.

One of the major drawbacks of the ready-to-drink protein shake is its long list of ingredients. The added nutrients make up the bulk of the list, but the drink has additives and preservatives, It’s also sweetened with the artificial sweeteners sucralose and acesulfame potassium.

Though generally recognized as safe, artificial sweeteners may not help with weight loss and may increase the risk of chronic diseases like Type 2 diabetes and heart disease ( 31 ). Limiting or avoiding artificial sweeteners may be better for your health.

At $2.00 a serving, Optimum Nutrition Gold Standard Ready-to-Drink Protein Shake is a good value. The Optimum Nutrition website says all supplements are sport-tested and checked for banned substances. This isn’t the same as third-party quality testing for safety and effectiveness.

What customers are saying

Customers on Amazon give Optimum Nutrition Gold Standard Protein Shake positive reviews. They like the taste, consistency, and nutrition profile. They also like that it’s high in protein and low in carbs and a good value.

Shae W. is drinking the shake for weight loss and writes, “They’re the healthiest option I could find for protein shakes, and I didn’t have to hold my nose while drinking.”

Not all reviewers like the taste, remarking that the shake is chalky and has a bad aftertaste. Critics also disliked the packaging. Verified buyer Herman notes, “Protein shakes manufacturers have switched to a cheaper “Tetra Pak” which leaks. This one leaks.”
