What's the Best Keto Protein Powder?
Our Favorite Low-Carb Whey Shakes Today

best keto protein powders review - cover

Finding the right keto protein powder on a low-carb high-fat diet, especially the keto diet, is a challenge.

There are so many ketogenic protein powders on the market, it’s tough to narrow down your choices no matter what your other dietary needs are. That's why when you need a low-carb shake it can be especially difficult to make the right choice.

This is the reason why we decided to get involved and review the best keto protein powders that we have found on the market this 2018.

And the truth of the matter is that, most supposedly "keto-friendly" protein powders aren't keto-friendly at all, but you'll learn that in just a little bit.

First and foremost, make sure you are getting as much nutrients as possible from natural sources by eating eggs, fish, meat, nuts, and other foods that are high in protein and low in carbohydrates to ensure weight loss. It’s unlikely you’ll reach your intake goals for each day with just food, so you might have to turn to supplements to get there.

Next, rule out a number of ketogenic diet shakes from your list of potential choices based on their general profiles. 

For instance, sweetened products are an option that improves the taste of the product, but it usually boosts the sugar content in the product. Many flavored or sweetened protein shakes contain about 8 to 10 grams more carbohydrates than unsweetened brands. If you want something with flavor, look for ones that utilize lower calorie sweeteners—preferably ones that are natural—for taste.

Also, make sure you consider absorption. All the ketogenic protein shakes in the world aren't going to do your body any good if your body is unable to assimilate it. Proteins are assigned a digestibility rating that’s called the "protein digestibility corrected amino acid score" that’s based on how well your body is able to digest the amino acid in the product. Whey, casein, and egg whites have higher scores than peas and hemp for example. The higher the score, the better your body is able to use the nutrient.

So, what are 2018's best low-carbohydrate protein powders in the market that are keto-friendly as well?

Here is a list of recommended low carb protein powders of 2018:

keto protein powders
  • BPI Sports ISO-HD Protein Powder
  • Perfect Keto Collagen
  • Optimum Nutrition Platinum HydroWhey
  • Nature's Best - Isopure Zero Carb Protein Powder
  • Kiss My Keto Protein Powder
  • Onnit Grass Fed Whey Protein Isolate
  • Julian Bakery Paleo Protein Powder
  • Naturade Vegansmart Plant-based Vegan Protein
  • Elevate Nutrition Plant-based Vegan Performance Protein Powder
  • Ora Organic Chocolate Protein Powder

Now, let's move forward with a detailed analysis of each one of these supplements.

Our Top-Rated Low Carb (Keto) Protein Powders

1. BPI Sports ISO-HD Protein Powder

BPI Sports is a newer company in the industry, but it’s gaining a strong reputation for its keto-friendly products. BPI offers a high-quality keto-friendly protein powder at an affordable price. According to their own ingredients list, each 33 gram serving of their ISO-HD has only 3 grams of carbohydrates and virtually no lactose.

It also features a high concentration of BCAAs to activate muscle growth and provides faster recovery after a workout. Its high concentration of the BCAA leucine, a powerful anabolic trigger, activates protein synthesis after physical exercise, supporting greater muscle growth and faster recovery. Despite BPI’s absence of added sugar, it’s still available in flavors that include banana cream pie, s’mores, chocolate brownie, and peanut butter candy bar. They definitely have different healthy recipes in store for you!

This keto-friendly protein powder is safe for your low-carb diet since, as we noted, it has almost no carbs in it. And, the reason why it stands at number one on our list is because among all the products that we've reviewed, it has good taste and absorbs well for ketogenic dieters. I wouldn't pass up on this brand if you are looking to bulk up and stay in ketosis at the same time.

You can also do a healthy scoop of this protein powder daily, before or after breakfast, between meals, pre or post workout. It will give you that energy boost that you're looking for to take your fitness to the next level because you get all healthy calories in every serving. And to take it to an even higher level, you can choose to add some natural unflavored collagen peptides (collagen protein products) per serving to increase results. To top it off, adding some MCT oil or coconut oil wouldn't hurt as well. 

Lastly, with BPI Sports ISO-HD also having very competitive prices, this product is surely well-deserving of the #1 spot on our list. You can click the link above to get the most affordable price for one of the best-tasting low carb protein powders (gluten-free as well) today!

2. Perfect Keto Collagen

Perfect Keto Collagen comes from one of the best known names in the keto supplement industry. As such, you can be reasonably sure going in that they’ve done at least a decent job producing a safe, reliable collagen supplement. Now whether it’s anything special or not remains to be seen. So, is it? 

Perfect Keto Collagen is a blend of medium chain triglycerides (MCTs) and collagen. MCTs are beneficial fatty acids known to be easy to digest while collagen provides the amino acids your body needs to replenish itself in the wake of strenuous activity. The two work together here to reduce appetite, improve mental acuity and memory and enhance neurological function. They also increase energy levels and are known to help prevent some types of liver disease and dysfunction.

Collagen is an outstanding alternative to dairy based proteins like casein, whey and egg protein powders. Whereas those kinds of protein can produce odious side effects for people who are lactose intolerant, there are no such issue with collagen. It provides the same complement of amino acids which makes it safer than most products.

Besides providing essential amino acids to help with muscle repair, collagen also helps restore a moist, supple texture to the skin by targeting the sub-dermal tissues for rejuvenation. And let’s not forget that it also helps build strong, flexible nails while simultaneously strengthening joints and connective tissues. Not bad for an “alternative” to dairy proteins.

So, after all that, we do think that this product is top-notch and we absolutely think it deserves a really high ranking on our list. But does it deserve the #1 spot? Almost. We do think that BPI Sports is still the best but Perfect Keto isn't far behind. You really can't go wrong with either of them, really close call.


  • Serving Size: ​1 scoop
  • ​Number of Servings: ​20 servings; 12 oz
  • How To Take: ​Mix 1 scoop per 8-10 oz of water.

3. Optimum Nutrition Platinum HydroWhey

Optimum Nutrition already has a reputation for making high-quality protein supplements and their protein powder is no exception. Hydrowhey is made from a concentrated source of hydrolyzed whey protein isolates and contains digestive enzymes which help to cut down on digestive distress and make it easier for the body to absorb the nutrients. These isolates are low in fats, sugar-free (gluten-free as well), and have no cholesterol.

Optimum Nutrition increases muscle mass, reduces body fat, and the specialized formula naturally enhances your lean muscle mass and strength. Optimum Nutrition Platinum Hydrowhey is instant so you can mix it easily with a spoon. This shake is available in chocolate, strawberry, vanilla, cookies & cream, and chocolate peanut butter flavors.

It can be used before, during, or after a workout or enjoyed any time throughout the day as an easy meal replacement or it can be a good pair if you are using any BHB products. It's a great protein powder overall, but it doesn't stand a chance compared to our #1 and #2 products on this list.

4. Nature's Best Isopure Zero Carb Protein Powder

Another entry on this list of "keto-friendly protein powders" is the Isopure Zero Carb from Nature's Best. It's one of our favorite brands today because it's completely packed with nutrients and you don't need to worry about your carbohydrate intake. With only 100% whey protein isolate powders, this product will juice you up for your next workout at the gym.

Made from a complete microfiltration process, this protein powder will work and dissolve perfectly in ice and water unlike most products. It's almost like clear milk when you mix it with water which is pretty amazing for these types of products. It's a great, healthy smoothie blend that can help you lose weight and bulk up. 

If you are looking for a whey product that won't kick you out of your hard-earned ketosis, then this is undoubtedly one of the better options out there because of its composition and pricing. So, if you're gonna shop for a whey protein shake that won't affect your ability to produce ketones during your low-carb diet, go ahead, give this keto protein powder a try.

5. Kiss My Keto Protein Powder

Kiss my Keto Protein Powder is a delicious blend of valuable nutrients, essential omega 3 fatty acids and amino acids that are vital in restoring damaged muscle tissue and creating new lean muscle in its place. Kiss my Keto Protein Powder can be taken either prior to or after finishing your workout and will provide myriad benefits in either case. When taken prior to your workout, it will produce an immediate and measurable energy boost that will help power you through barriers. Or you can take it after your workout to provide your body the nutrients it craves as it goes about the process of repairing damage and building a stronger muscular foundation.

Kiss my Keto is not only a formidable protein supplement, it’s also blissfully free of the artificial ingredients so many other, lesser protein powders rely on to bolster taste or increase bioavailability. 

Kiss my Keto is loaded with BHB salts that help stabilize blood glucose levels and enhance insulin sensitivity, calcium which is essential in helping to build and maintain a healthy skeletal system to hang your new muscles on, magnesium to provide increased energy, calm the nerves and aid in more restful sleep and L-citrulline. L-citrulline is one of those essential amino acids we mentioned above and helps you maintain a healthy heart and robust immune system.

Those who want to enjoy the benefits of ketosis and see better, more durable results in the gym - without having to endure the side effects from impure or inappropriate ingredients - will love Kiss my Keto. It’s really as simple as that.

6. Onnit Grass Fed Whey Protein Isolate

Onnit is a full service health products company producing everything from kettlebells to nootropics and more conventional supplements like this Whey Protein Isolate. This product actually fills what was a fairly obvious gap in their nutritional lineup. Since the closest they’d come to it previously was a goat milk whey drink intended to aid in recovery from strenuous workouts. So now, they’ve finally thrown their hat into the protein powder ring and we’re happy to say the results were worth the wait.

Onnit Grass Fed Whey Protein Isolate contains no artificial sweeteners like many other protein supplements do. It’s also devoid of artificial flavors but that doesn’t mean it’s flavorless. Quite the contrary. The Mexican Chocolate, while not quite what you are probably expecting, nonetheless has a chocolaty, let’s call it “character”, rather than taste that’s as delightful as it is unexpected. While the vanilla steers a course back toward more predictable flavorings and leaves a mild aftertaste that doesn’t linger so long it becomes an issue.

The whey here is derived from the milk of free range dairy cattle, should that matter to you. And of course such a luxury usually means you’re going to pay a premium price. And you will. Although it’s not all that much more than the competition. When all is said and done Onnit provides a high quality protein isolate supplement that will fill your nutritional needs and taste great doing it.


  • Serving Size: ​​​1 scoop
  • ​Number of Servings: ​​​​​30 servings; 27.5 oz
  • How To Take: ​​​​​Mix 1 scoop with at least 8 oz of water or your favorite beverage.


  • ​No artificial sweeteners or other ingredients
  • ​20 grams of protein per suggested serving
  • ​Low in carbs for keto dieters
  • ​No sugar, 2 grams fat and no cholesterol
  • ​Loaded with digestive enzymes and probiotics
  • ​Also contains lactobacillus acidophilus


  • It’s going to cost more than most others
  • Not quite as effective as the other products

7. Julian Bakery Paleo Protein Powder

While there is nothing on the surface that necessarily pops out at you and says Julian Bakery Paleo Protein Powder is anything particularly special, a closer look reveals what all the fuss has been about regarding this particular supplement. It’s the fact that you can order your Julian Bakery protein in one of two forms: either as 100% egg white protein or 100% beef protein. This means that the company is aware and sensitive to the fact that millions of people out there suffer from lactose intolerance and are often excluded from taking some of the best whey protein supplements because they’re derived from dairy products.

The standard serving of either their egg or beef protein is 25 grams with each serving, providing 4.3 grams of protein, 1 gram of fat, 2 grams of carbs and a total of 108 calories. That low, low carb total means Julian Bakery protein powders are a good choice for those on the keto diet as well. So the hits just keep coming with Julian Bakery.

From a nutritional standpoint, neither egg nor beef protein boast the level of bioavailability that some other types of protein do (especially plant-based proteins). But the difference is not one most people are going to notice. It is loaded with beneficial probiotics, gluten free and contains no GMOs or artificial additives.


  • Serving Size: ​​​1 scoop
  • ​Number of Servings: ​​​​​​30 servings; 2 lb
  • How To Take: ​​​​​​Mix 1 scoop with at least 8 oz of water or your favorite beverage.


  • ​Ideal for those with lactose intolerance
  • ​Natural sweeteners including monk fruit
  • ​Improves overall muscles strength
  • ​Enhances weight loss efforts
  • ​Dovetails with your keto lifestyle
  • ​30 day supply in each package
  • ​For drinking, eating or baking


  • The donut smell is a little off
  • Availability can sometimes be an issue
  • Taste is not comparable with the top products on this list

8. Naturade Vegansmart Plant-Based Vegan Protein

Vegansmart Plant-Based Vegan Proteins from Naturade stand out for the ease with which they mix with your preferred beverage to create silky smooth protein shakes. While the protein content in an average serving is not as generous as it is with some other protein supplement this is plant-based protein which means it doesn’t have to be. Why? Because plant-based proteins are prized for their outstanding levels of bioavailability. Meaning a little bit goes a long way.

You might read reviews bemoaning the relatively low protein load per serving but they miss the point. The entire attraction, the whole reason plant-based protein powders have taken the industry by storm is because of they go about their job so efficiently. The five different plant-based proteins used here add up to the vegan equivalent of a protein bomb. And that’s what you need if you exercise regularly and want to keep progressing while maintaining energy levels and increasing stamina.

But Vegansmart shakes don’t stop with the most bioavailable type of protein around. They also provide 22 vitamins and minerals to ensure that when the protein goes to work it’s not alone. There’s also 6 grams of dietary fiber and essential omega 3 fatty acids to help with heart and brain health. And of course such a well-rounded protein supplement is going to include plenty of probiotics to help everything from digestion to a stronger immune system.


  • Serving Size: ​​​​2 scoops
  • ​Number of Servings: ​​​​​​​15 servings; 1.5 lb
  • How To Take: ​​​​​​​Mix 2 scoops of the powder in your smoothie or choice of liquid.


  • ​Completely free of genetically modified organisms
  • ​Rich in omega 3 fatty acids
  • ​An all-in-one shake mix that’s perfect at any time of the day
  • ​Includes nearly 2 dozen vitamins and minerals
  • ​Contains no gluten, dairy, soy or cholesterol
  • ​Certified vegan safe


  • 5 grams of sugar per serving

9. Elevate Nutrition Plant-Based Vegan Performance Protein Powder

Elevate is a small company with big ambitions and if they continue to produce products like their plant-based Vegan Performance Protein Powder they’ll be on their way to the big time soon enough. This is a surprisingly effective vegan protein powder that’s perfect for those whose ambitions are more focused on building muscle mass, achieving personal best after personal best and minimizing their sugar and carb intake.

The thing about this type of vegan protein powder is that “vegan” is not a dirty word the way it can be with some other supplements or foods. No one here is hiding being the vegan label and using it as an excuse for poor performance. Quite the contrary. Since plant-based proteins exhibit a higher degree of bioavailability than dairy based proteins like whey or casein you might want to drop your current protein supplement and switch to this vegan alternative.

Elevate is free of sugar or sugar substitutes, contains essential omega 3 fatty acids and is high in BCAAs (branched chain amino acids) that are so crucial to repairing muscle tissue and building taut, hard new muscle. And as a little added bonus you won’t suffer the gas that whey can sometimes gift you with.


  • Serving Size: ​​​​​1 scoop
  • ​Number of Servings: ​​​​​​​​26 servings; 2 lb
  • How To Take: ​​​​​​​​Mix 1-2 scoops with your favorite liquid


  • Certified vegan, made from 100% plant-based proteins
  • ​ A higher degree of bioavailability than dairy based protein
  • ​Free of dairy, soy and genetically modified organisms
  • ​Ideal for those looking to lose weight and build muscle
  • ​Made in the US in an FDA certified facility


  • ​Taste leaves something to be desired

10. Ora Organic Chocolate Protein Powder

The last item on our list is Ora Organic Chocolate Protein Powder. Ora Organic puts a lot of effort into R&D and it’s obvious here. There are multiple digestive enzymes including amylase, protease and lipase to help with absorption and stave off gastric discomfort. There are essential fatty acids, micro and macro micronutrients, organic cocoa and more than 20 other organic superfoods. They’re all combined to produce a vegan safe protein powder that’s serious about repairing muscles, enhancing energy levels and helping you lose weight.

Ora Organic Chocolate Protein Powder is easy on your stomach and glides effortlessly through your system to make itself readily available faster and more completely than any animal based protein powder. That’s why the serving size of 19 grams is so modest. You simply don’t need as much as you would if this were whey or casein protein powder.

Ora Organic Chocolate Protein Powder will help you find the energy to attain new personal bests while at the same time improving mental acuity and clarity and virtually eliminating fatigue. All ingredients used in the production of this protein powder are certified vegan and sourced from organic farms in North America, Europe and Asia. If you’re looking for a vegan friendly protein powder that packs a punch you can’t beat Ora Organic Chocolate Protein Powder.

When is the Best Time to Take Protein Powders?

The benefits of the various protein powders profiled above are well-known (and if they weren’t before they will be in a moment).

Protein powders play a key role in enabling the physically active to enhance their energy levels, create lean, strong muscle mass, increase their metabolism and burn fat efficiently and effectively. Especially so if they are used in concert with the keto diet. But sometimes, the biggest question people have about this type of supplement is not “should” they take it but “when” they should take it. Here are the options:

dumbell and wall clock
  • Before workout - Many experienced bodybuilders and physical fitness buffs like to take their protein powder supplement about half an hour before working out. To their thinking, it provides you with an energy boost and your muscles with a jolt of nutrients they’ll use to maintain their integrity even when you’re pushing through barriers.
  • Post-workout - In the hours after coming from the gym, your muscles are most in need of protein. This is why many hard bodies schedule their protein shakes for the post workout period. Strenuous workouts cause the breakdown of muscle tissue. Particularly if you’re exercising to muscle failure (which you should be if you want real growth). A quick injection of essential amino acids after a workout hastens tissue repair and enhances the growth cycle of new tissue.
  • check
    ​Before going to bed - This is a favorite habit of those who take casein protein powders as casein is prized for its slow release properties. Taking casein based protein products before going to bed enables your body to continue its repair and rebuilding cycle even after you are off in dreamland. Sleep, as it turns out, is not just an opportunity for your subconscious to process things that are currently unresolved, it’s also vital that your body have this downtime to undergo some self-diagnostics and begin the process of effecting repairs. So if your protein of choice is casein having your shake half an hour before turning in is a great way to help your body as it goes through its repair and replacement cycles.
  • check
    Upon waking up - By the time you wake up your body has been without any nutrient input for perhaps eight hours or more. In essence, your body is a clean slate as just about everything from the previous day has been metabolized and your system is on hold waiting for new input. Many health professionals believe this is the best time of day to indulge in your protein shake. It will give you an immediate energy boost and set you up with a nutritional foundation that will help stabilize energy levels as you go through your day.

3 Major Benefits of Keto Protein Powders:

Protein powder is not a magic bullet that’s going to cure you of all ills and transform you from Bruce Banner into the Hulk overnight.

It’s a dietary supplement intended to provide your system with the nutrients it needs to repair the damage you do either in the normal course of your workday or by way of intentional damage inflicted in the gym. Besides providing the building blocks for a leaner, stronger you, however, there are a number of other benefits to be gleaned from protein powder that you may or may not be aware of, including:

  • Weight loss - A protein shake is going to help you lose weight? That’s right. As long as you don’t follow it with a large pizza and a six pack. Studies have shown that by cutting caloric intake and substituting with a protein shake, you can lose more weight than if you just stuck to the caloric restrictions. Why? Because protein supplements not only provide you the building blocks of strong new muscles, they also help stimulate the metabolism which causes your body to burn fat at an accelerated rate. The somewhat mysterious fact is that a protein shake per day has also been shown to promote weight loss even in people who have not cut their caloric intake. Once again, researches attribute this to increased metabolic rates.
  • ​Alleviating hunger - One of the toughest aspects of dieting is dealing with food cravings. This is especially true if you are attempting to adhere to the keto diet. Cravings for sweets, pasta, French fries, ice cream and more can be intense. And if you don’t have some mechanism in place to deal with those cravings you’ll likely succumb to temptation at some point. Protein shakes are a great way to stave off cravings. They provide you with a feeling of being full or ‘satiated’ that is much more satisfying than the feeling you’ll get from carbohydrates or fats. By falling back on protein shakes then you’re not only giving your muscle building efforts a boost, you’re also boosting your ability to stay on the weight loss path without suffering.
  • check
    Additional benefits - Of course as we mentioned at the outset most people use protein shakes as a way to help them repair and build muscle. And it does a wonderful job at that, regardless of whether you’re using casein or whey or pea or beef protein. Some studies have suggested that whey protein may also play a role in the prevention and treatment of metabolic conditions. The mechanism for doing so seems linked to the ability of whey protein to reduce blood pressure and stabilize blood glucose levels (two more benefits of protein powder). The results are preliminary and more study is certainly needed, but early results are promising.

How Much Protein on the Keto Diet?

different kinds of protein

The recommended daily protein intake to maintain ketosis is between 0.6g to 0.8g per pound of muscle (lean body mass). This amount prevents your body from starting gluconeogenesis so that you can maintain the state of ketosis.

Although, some people might be able to get away with a higher level of protein intake but this is not very common.

For most people to stay on the keto diet, 15% of your daily macros should be protein and nothing too far or too short of that amount.
