A Quick Look at the Best Keto Protein Powders

Muscletech’s NitroTech is designed to boost recovery, performance, and strength. It does this by packing 30 grams of protein isolates and peptides, 5 grams of Glutamine and its precursors, 6.8 grams of branched-chain amino acids, and 3 grams of Creatine Monohydrate in each serving.

Nature’s Best Zero CarbIsopure presents a good option for those looking for a protein powder that’s lactose and/or gluten free. Each serving provides 50 grams of protein, a blend of multivitamins and minerals, branched-chain amino acids, and 4.6 grams of L-glutamine.

BPI Sports ISO HD is a whey protein isolate supplement designed to provide protein at a fast rate, improving both recovery time and muscle growth. Each serving provides 25 grams of protein in isolate and hydrolysate forms.

Platinum Hydro Whey is made with advanced whey protein isolates to ensure that protein gets into muscles faster. Each serving would give you 30 grams of protein and about 9 grams of naturally occurring branched-chain amino acids (leucine, isoleucine, and valine).

Keto Collagen is a lactose-free protein supplement for those currently in a ketogenic diet. Each serving would give you 10 grams of protein (derived from grass-fed bone broth) and 5,000 milligrams of healthy fat (medium-chain triglycerides).

Reviews of the Best Keto Protein Powders


On paper, NitroTech is among the top when it comes to protein content. But, once you see how large their scoop is, you’ll realize that you’re just taking in a lot of protein powder for every serving.

Despite this, NitroTech gives good value for its low carbohydrate content and optimal Creatine content. With this product, you’d be taking calories packed with protein.

coolimagecoolimagecoolimageMuscleTech NitroTech Whey Protein Powder

If you could get over the ridiculous amount of artificial sweeteners, it would be a great pre- and post-workout protein powder – especially if you’re aiming for weight loss.

Things We Liked

  • High protein content
  • Minimal carbohydrates
  • Good source of Creatine

Things We Didn't Like

  • Large serving size
  • Contains artificial sweeteners
  • Can cause stomach upset
coolimagecoolimagecoolimageIsopure Zero Carb Protein Powder

This is a good pre-workout and morning drink. With Isopure protein powder using whey isolates and having minimal carbohydrates, you’re getting as much protein as you can get from each serving.

Just make sure to gradually adjust into taking the full serving of the product. Going from zero protein supplementation to full serving can give you gas or cause stomach upset.

Also, note that despite its name, the product isn’t a vegan protein source.

Things We Liked

  • Uses whey isolates
  • Good basic nutritional supplementation
  • Low carb content

Things We Didn't Like

  • Pretty basic for its price range
  • Artificially sweetened taste is noticeable
  • Flavors are far from accurate

Optimum Nutrition is one of the well-known brands out there due to their reputation and history in the industry of sports and fitness nutrition. This still holds true with their whey as it’s one of the most cost-effective per serving.

However, with their new formulation, they have removed the digestive proteases that improve protein absorption. Furthermore, they added sugar substitutes and artificial sweetener for better flavor.

coolimagecoolimagecoolimageOptimum Nutrition Whey Protein Powder Gold Standard

You can purchase their naturally flavored variants, which are often pricier.

Things We Liked

  • Cost effective
  • Not too sweet
  • Uses whey isolates

Things We Didn't Like

  • Doesn’t contain digestive proteases
  • Presence of sugar substitutes
  • Inferior to previous formulation

There’s no difference between the amount of protein your body can get from whey protein supplements, milk protein suppleme​​​​nts, and casein protein supplements. However, this does not mean that they can be used in the same way.

By using pregnenolone cream or pregnenolone supplements, the levels of the compound in the body increases, and this brings about various benefits such as fatigue relief, and delay of the aging process.
coolimagecoolimagecoolimageNOW Foods Eggwhite Protein Powder

A protein powder made of egg whites is a good option for those looking to supplement with protein but intolerant of lactose.

But, the gas it gives to those who take it is quite a bit of a deal breaker. Furthermore, for the amount of protein it provides, it is quite expensive for its price range.

Things We Liked

  • Lactose free (from egg white protein)
  • Good protein content
  • Pleasant taste

Things We Didn't Like

  • Quite expensive per serving
  • Would give you gas
  • Hard to mix

This product is designed to provide protein at the most optimal rate of absorption – and that’s achieved through the presence of protein hydrolysate.

BPI Sports’ offering comes in several flavors (such as chocolate and vanilla), but most of them don’t taste great at all. As for texture, well, there’s really nothing to complain about.

coolimagecoolimagecoolimageBPI Sports ISO HD Whey Protein Powder

Things We Liked

  • Low carb
  • Pure whey isolates
  • Good amino acid content

Things We Didn't Like

  • Bad flavor
  • Artificial sweeteners
  • Could upset your stomach
coolimagecoolimagecoolimageOptimum Nutrition Platinum Hydrowhey Protein Powder

Platinum Hydro Whey is your all-in-one protein supplement. It has all the amino acids your body would need to effectively absorb protein.

We found that it’s quite easy to mix with the aid of a shaker. However, the taste could do with a bit of an improvement – for better flavor, get the chocolate or vanilla and mix it with banana.

Things We Liked

  • Whey protein isolates
  • Loaded with amino acids
  • Easy to dissolve with a shaker

Things We Didn't Like

  • Not-so-pleasant taste
  • Contains soy lecithin
  • Reports of unsealed bottles

This one’s a very good option when you’re on the keto diet. It’s lactose free and would give you the best amount of protein no matter how limiting your low-carb diet might be.

coolimagecoolimagecoolimagePerfect Keto, Keto Collagen Protein Powder

Things We Liked

  • Sourced from grass-fed cows
  • Good taste
  • MCT oil powder content
  • Lactose free
  • No fillers or additives

Things We Didn't Like

  • Doesn’t always easily dissolve
  • Not advisable for making butter or keto coffee
  • Reports of discolored protection seals
coolimagecoolimagecoolimageBioTrust Low Carb Grass-Fed Protein Powder

We like that it’s sourced from certified hormone-free and grass-fed cows. The combination of different whey and casein protein makes it rather versatile, but the taste can be a really big turn-off.

Things We Liked

  • Low net carb
  • Sourced from grass-fed cows
  • Mix of whey isolate and casein

Things We Didn't Like

  • A bit too sweet
  • Doesn’t contain MCT or coconut oil
  • Some flavors are too strong

The combination of whey and casein isolates makes it a good source of protein throughout the day. However, it does have a chemical aftertaste that greatly affects its palatability.

This is why many choose to integrate it into an existing recipe. Yes, it’s possible to turn your favorite smoothie, ice cream, keto bread, almond milk, and even Greek yogurt into something that better suits your diet.

coolimagecoolimagecoolimageQuest Nutrition Protein Powder

Things We Liked

  • Combination of casein and whey isolates
  • Easily mixed with a shaker
  • Good protein content
  • No added sugar

Things We Didn't Like

  • Artificial flavors (sucralose)
  • Sometimes has chunks
  • Chemical aftertaste

Studies shown that whey protein powders get absorbed the fastest, while casein protein supplements provide a slow and steady source of protein for up to eight hours.

By using pregnenolone cream or pregnenolone supplements, the levels of the compound in the body increases, and this brings about various benefits such as fatigue relief, and delay of the aging process.

How to Choose Protein Powders

Know Your Needs

There’s no difference between the amount of protein your body can get from whey protein supplements, milk protein supplements, and casein protein supplements. However, this does not mean that they can be used in the same way.

Studies have shown that these three protein supplements are absorbed at varying rates.

So, if you’re looking for a quick source of protein after a workout or upon waking in the morning, whey protein is the best kind of protein powder for you. But, if what you need is a protein source for extended periods like during sleep or throughout the day, casein protein powder is ideal.

Isolates Over Concentrates

Protein powders containing protein isolates are always better than those containing protein concentrates. It’s true though, that they mainly differ in the extent of filtration during production.

To put it simply, protein isolates contain at least 90% of whey, while protein concentrates range from 25% to 89% whey protein. The remaining percentage would contain lactose, milk fat, or both – all of which are unnecessary to the goals you’re trying to achieve.

With isolates, you’re getting more protein per gram. And, with more protein per gram, you’re getting more value for your money.

Protein isolates contain at least 90% of whey, while protein concentrates range from 25% to 89% whey protein. The remaining percentage would contain lactose, milk fat, or both – all of which are unnecessary to the goals you’re trying to achieve.

By using pregnenolone cream or pregnenolone supplements, the levels of the compound in the body increases, and this brings about various benefits such as fatigue relief, and delay of the aging process.

On the Matter of Fillers

A protein powder supplement contains ingredients other than protein – and those are generally referred to as fillers. These could include substances for improving flavor, shelf-life, taste, or effect.

Of course, we would want to get the best value so as much as possible we want none of these substances in our protein powder. But, that’s quite unrealistic since some fillers are necessary for a protein powder supplement to give the best effect.

So, the secret is to identify those fillers that you’ll always have to avoid. If you see any of these in a supplement you’re planning to purchase, don’t hesitate to look for another one:

  • Glucose and/or dextrin

The Verdict

Best Low Carb Protein Powder: Quest Nutrition Protein Powder

If you’re looking for a protein powder with no added sugars and low on carbohydrates, we recommend Quest Nutrition Protein Powder. With it containing whey and casein, you can use it both as a protein source post-workout and as a constant protein source for the whole day.

Best Protein Powder for the Ketogenic Diet: Perfect Keto, Keto Collagen Protein Powder

For those with difficulties processing lactose, Perfect Keto’s Keto Protein Powder is highly recommended. Aside from serving as a great source of exogenous ketone body(or ketones), it has everything that you’d need for your ketogenic or high-protein diet.

All in all, while there’s always the matter of preference, you’ll probably have a hard time looking for other products that could compete with the best keto protein powder in our article.
