The Best Protein Powders For Keto Diet, Reviewed

#1Best Overall

Isopure Low Carb Whey Isolate Protein Powder

Isopure Low Carb Whey Isolate Protein Powder
Protein per serving25g
Carb content0g sugar, low carb
Protein type100% whey protein isolate
Servings per bag14
Ingredients count5 or less
Check Latest Price →

What We Like

  • Zero grams of sugar per serving
  • 100% pure whey protein isolate
  • Only 5 or less ingredients

Trade-offs

  • Only 14 servings per bag
  • Vanilla Bean flavor only in this size

Each serving packs 25 grams of pure whey isolate with zero sugar and just five ingredients, so you can hit your protein goals without worrying about hidden carbs. The blend of 8 ingredients supports everyday nutrition for any lifestyle, making it a keto-friendly option that fits into a low-carb routine. This straightforward approach lets you focus on your wellness goals without unnecessary additives.

The 14-serving bag is smaller than some alternatives, like Quest Nutrition’s peanut butter powder, which provides 23 servings per container. For daily use, you may need to reorder more often. But if you prioritize a short ingredient list and minimal carbs, this vanilla bean shake delivers exactly what you need.

Best for: Those who want a low-carb whey isolate with minimal ingredients and zero sugar. Not ideal for those who need a larger supply per purchase.
#2Best Complete Protein Blend

Quest Nutrition Peanut Butter Protein Powder

Quest Nutrition Peanut Butter Protein Powder
Protein per scoop23g
Net carbs per scoop2g
Sugar per scoop<1g
Protein blendWhey Isolate & Micellar Casein
Servings per container~24
Check Latest Price →

What We Like

  • 23g protein with only 2g net carbs
  • Dual-source protein for fast and slow absorption
  • Less than 1g sugar per scoop
  • Complete dairy-based proteins

Trade-offs

  • Not suitable for dairy-free or vegan diets
  • Contains whey and casein, which some avoid

Twenty-three grams of protein with just two grams of net carbs and less than one gram of sugar per scoop makes this a remarkably efficient option for anyone watching their carb intake on keto. The blend of sixty percent fast-absorbing whey protein isolate and forty percent slow-absorbing micellar casein means you get an initial hit of amino acids after your workout. That’s followed by a steady release over the next few hours, which is exactly the kind of sustained support that helps muscle recovery without spiking your blood sugar. It suits the person who wants a straightforward, dairy-based protein powder that fits tight macros and still tastes like a treat.

The trade-off here is that this is a dairy-based product, so if you are plant-based or avoiding lactose, you will want to look elsewhere. Compared to the Orgain Organic Vegan Protein Powder, which uses pea and brown rice protein, Quest delivers a more traditional protein profile but misses the vegan crowd entirely.

Best for: Keto dieters who want a complete dairy-based protein blend with minimal carbs and a steady release of amino acids. Not ideal for vegans or those avoiding dairy.

#3Best Keto Macro Split

KetoLogic Keto Meal Replacement Shake

KetoLogic Keto Meal Replacement Shake
Net Carbs3g per serving
Protein SourceWhey Protein Isolate
MCT ContentIncludes MCT Oil
Servings20 per container
SweetenersNo artificial sweeteners
Check Latest Price →

What We Like

  • Only 3g net carbs per serving
  • Sugar-free and gluten-free formula
  • No artificial flavors or sweeteners

Trade-offs

  • Not suitable for those avoiding dairy
  • Contains whey protein, unsuitable for vegans.

At just 3g net carbs per serving, this shake is built from the ground up for staying in ketosis while still feeling like a real meal.

The trade-off is that this shake uses whey protein isolate, which is a dairy-based protein. For those who avoid dairy entirely, a plant-based option like Orgain Organic Vegan Protein Powder would be a better fit. For most keto followers, though, the focused macro design, 3g net carbs per serving, makes it a straightforward choice.

Best for: Keto dieters who want a low-carb shake with MCT oil and no artificial ingredients. Not ideal for those with dairy sensitivities or who prefer a plant-based protein source.
#4Best With Bone Broth

Ancient Nutrition Keto Protein Powder

Ancient Nutrition Keto Protein Powder
Carbs per serving3g
Calories per serving170
Key ingredientsBone broth, MCT oil, ashwagandha
Check Latest Price →

What We Like

  • Non-GMO, gluten free, dairy free, soy free
  • Includes caffeine, ashwagandha, and reishi mushrooms
  • Mixes easily in shakes or coffee under 60 seconds

Trade-offs

  • Only 17 servings per container
  • Contains caffeine, not ideal for evening use

It brings in caffeine for energy, ashwagandha for stress support, and reishi mushrooms, ingredients that go beyond plain protein. That makes it a smart fit if you want a supplement that does more than just hit macros, especially if you’re already comfortable with bone broth as a protein source.

The trade-off comes down to serving size: 17 servings per container means you’ll restock sooner than with larger tubs like Quest’s 23-serving bag. And while 3 grams of carbs is low, it’s not zero, so if you’re tracking every gram, a zero-carb option might suit you better. But for someone who values functional ingredients and a keto-friendly fat profile, this is a well-rounded choice.

Best for: Keto dieters who want a functional protein with bone broth, MCTs, and adaptogens. Not ideal for those needing zero carbs or a larger supply per purchase.

#5Best Plant-Based Pick

Orgain Organic Vegan Protein Powder

Orgain Organic Vegan Protein Powder
Protein per serving21g
Carbs (net)Low net carb
Fiber6g prebiotic + fiber
SweetenerNo added sugar
CertificationsUSDA Organic, Vegan
Check Latest Price →

What We Like

  • 21g organic plant protein per serving
  • No added sugar or artificial sweeteners
  • Includes 6g prebiotic fiber for gut support
  • Free of soy, gluten, dairy, and carrageenan

Trade-offs

  • Only 20 servings per container
  • Not a pure protein isolate, fiber adds carbs

Twenty-one grams of organic plant protein with zero added sugar make this a clean choice if you’re avoiding artificial ingredients. The blend of pea, brown rice, and chia delivers all nine essential amino acids without whey or soy, which is unusual for a plant-based powder. That 6g of prebiotic fiber also supports digestion, so you’re feeding your gut while getting protein. It works well for anyone who wants a shake with organic, plant-based ingredients that skips the artificial stuff entirely.

With only 20 servings per tub, you’ll go through it faster than some other picks here, and the fiber contributes to your daily carb count, something to track if you’re strict about macros. Compared to the Isopure Low Carb Whey Isolate, which packs 25g of protein per serving, this Orgain option is better suited for someone who values organic ingredients and plant-based nutrition over maximum protein density. It’s not a pure isolate, but it’s a well-rounded choice for plant-forward eaters.

Best for: Vegans and plant-based eaters who want organic protein with gut-friendly fiber. Not ideal for those needing ultra-low-carb, high-protein isolates or more servings per container.
#6Best Zero Carb Option

Isopure Zero Carb Whey Isolate Protein Powder

Isopure Zero Carb Whey Isolate Protein Powder
Protein per serving25g
Carbs per serving0g
Sugar per serving0g
Protein source100% Whey Isolate
Vitamins & minerals20 added
Check Latest Price →

What We Like

  • 25g protein from 100% whey isolate
  • Ultra-filtered to remove fat and carbs
  • Includes 20 vitamins and minerals

Trade-offs

  • Unflavored only in this size
  • No added fats for keto meal replacement

A full spectrum of 20 vitamins and minerals, including vitamins A, C, E and zinc, provides immune support right alongside the muscle recovery benefits of the protein. For someone following a keto diet that limits fruit and vegetable variety, that built-in micronutrient coverage helps fill common gaps without extra planning. Reviewers find it a practical way to get both protein and daily vitamin needs met in a single scoop.

The unflavored version has no taste, so it mixes into anything without clashing, but it won’t satisfy a craving for a sweet shake. Compared to the Isopure Low Carb option, which has 5 or less grams of carbs per serving, this one is the stricter choice for those who track every carb. It also lacks added fats, so it works best as a pure protein supplement rather than a meal replacement. If your diet demands absolute carb control and you do not mind mixing your own flavors, this is a clean protein-only option.

Best for: Keto dieters who want a pure, carb-free protein boost without any added sugars or flavors. Not ideal for anyone seeking a meal replacement shake with built-in fats or a flavored ready-to-drink option.
#7Best Grass-Fed Beef Protein

Equip Foods Prime Protein Powder

Equip Foods Prime Protein Powder
Protein per serving21g+
Protein sourceGrass fed beef isolate
SweetenersCoconut sugar, monk fruit
Diet compatibilityKeto, paleo, carnivore
Flavor count8 indulgent options
Check Latest Price →

What We Like

  • No added sugar, soy, dairy, or gluten
  • 21g+ complete protein from grass fed beef
  • Includes collagen and gelatin for recovery
  • 30-day refund if unsatisfied

Trade-offs

  • Not suitable for plant-based diets
  • Contains beef protein, which some avoid

Each serving delivers 21g+ of complete protein from grass fed beef isolate, matching the protein content of a 4oz steak. It fits keto, paleo, and carnivore diets without added sugar, soy, dairy, or gluten, so it’s a clean option that won’t cause bloating. The inclusion of collagen and gelatin supports post-workout recovery, and the Cinnamon Roll flavor is sweetened with coconut sugar and monk fruit for a dessert-like taste.

This is a beef protein isolate, so if you prefer plant-based options like the Orgain Organic Vegan Protein Powder, this won’t work for you. And while there are eight flavors to choose from, the Cinnamon Roll variety is the only one in this specific listing, so you’ll want to check if that dessert-like profile fits your taste. For keto dieters focused on whole-food ingredients without fillers or artificial junk, this delivers on the promise of simple, nutrient-dense fuel.

This beef protein isolate is not suitable for plant-based diets, so if you prefer vegan options like the Orgain Organic Vegan Protein Powder, look elsewhere. The Cinnamon Roll flavor is the only one in this listing, so make sure that dessert-like profile appeals to you. For keto dieters focused on whole-food ingredients without fillers or artificial additives, this delivers a simple, nutrient-dense protein source.

#8Best Collagen With MCT

Orgain Keto Collagen Protein Powder

Orgain Keto Collagen Protein Powder
Protein per serving10g
MCT oil per serving5g
Calories per serving90
Collagen typeType I & III
Dietary certificationsNon-GMO, Gluten Free
Check Latest Price →

What We Like

  • 2:1 protein-to-fat keto ratio
  • Grass-fed hydrolyzed collagen peptides
  • No added sugar or artificial ingredients
  • Dissolves easily in hot or cold

Trade-offs

  • Only 10g protein per serving
  • Chocolate flavor only

With 10 grams of grass-fed hydrolyzed collagen and 5 grams of MCT oil per serving, this powder hits a clean 2:1 protein-to-fat ratio that fits neatly into a keto day. The collagen supports hair, nails, and skin as stated, while the MCT helps raise ketone levels and supplies energy, so you get beauty and fuel in one scoop. It dissolves easily in hot coffee or cold smoothies, making it a simple add-on for anyone who wants collagen benefits without breaking ketosis.

If your goal is a collagen boost with keto-friendly macros rather than a full protein fix, this is a cleaner, more targeted option. At 10 grams of collagen per serving, it’s lighter than a meal replacement like KetoLogic’s shake, which is formulated with MCT oil and whey protein isolate for fuller satiety. No artificial flavors, no sugar, and it mixes without clumps, just a straightforward way to support your hair, nails, and energy all at once.

Best for: Someone on a keto diet who wants collagen for hair, skin, and joints plus a quick MCT energy lift, not a high-protein meal replacement. Not ideal for those needing 20g+ protein per serving.

#9Best With Creatine

Vega Protein + Creatine Plant Based Powder

Vega Protein + Creatine Plant Based Powder
Protein per serving30g
Creatine per serving3g
Carb profileLow carb
SourcePlant based
Servings13
Check Latest Price →

What We Like

  • 30g plant protein plus 3g creatine
  • Low carb and keto-friendly
  • Reduced bloating formula
  • Fast mixing, no chalky texture

Trade-offs

  • Not suitable for whey protein users

A single scoop that packs 30 grams of plant protein plus 3 grams of creatine means you get both muscle-building support and recovery help in one shake. That dual punch makes this a smart pick if you want to keep your routine simple while staying keto-friendly. The low carb count fits ketosis without guesswork, and the formula is designed to reduce bloating, so you feel light after drinking it rather than weighed down. It mixes fast in water or smoothies with a smooth, clean taste, which matters when you just want to finish your post-workout shake and move on with your day.

A 13-serving container means you will restock more often than with larger tubs from competitors like Isopure Low Carb Whey Isolate. But the 30 grams of plant-based protein plus 3 grams of creatine in each scoop is a combination you rarely find in a single vegan powder. The formula is designed to reduce bloating, so if other blends leave you feeling heavy, this one may sit easier. It is a targeted solution for anyone who wants creatine without juggling multiple supplements.

Best for: The keto dieter who wants a single plant-based powder that combines protein and creatine for muscle recovery. Not ideal for someone who needs a high number of servings per container or prefers whey-based protein.

#10Best Collagen-Enriched Keto Shake

Keto Science Ketogenic Meal Shake

Keto Science Ketogenic Meal Shake
Protein SourceCollagen & MCT Oil
Servings14
FlavorVanilla
Diet TypeKeto & Paleo Friendly
Check Latest Price →

What We Like

  • Includes hydrolyzed collagen for skin health
  • Rich in MCTs for energy and focus
  • Packed with vitamins and minerals
  • Gluten-free and keto-friendly formula

Trade-offs

  • Only 14 servings per container
  • Not suitable for those avoiding whey or dairy

With hydrolyzed collagen and MCT oil packed into every scoop, this shake targets two things at once: steady energy for keto dieters and support for skin health. The vanilla flavor mixes up creamy and quick, making it a convenient meal replacement or post-workout option when you’re on the go. It’s designed specifically for low-carb lifestyles, so you won’t have to guess whether it fits your macros.

The trade-off here is serving count: 14 servings means you’ll restock sooner than with a 20-serving tub like KetoLogic’s Keto Meal Replacement Shake. The formula includes hydrolyzed collagen, which supports skin and overall health, but it’s not a complete protein source. If you’re looking for a shake that provides MCT energy and collagen in a keto-friendly vanilla shake, this one fits the bill.

This shake is ideal for keto dieters who want the benefits of collagen and MCT oil in a convenient vanilla shake. It’s not ideal for those who need a larger serving count per container, as the 14 servings require more frequent restocking compared to some competitors.

Best for: Keto dieters who want collagen and MCT oil in a convenient vanilla shake. Not ideal for those needing a larger serving count per container.

How We Evaluated Protein Powders For Keto Diet

Our evaluation focused on what matters most to someone maintaining ketosis. We dug into nutrition labels, ingredient lists, and manufacturer documentation to verify net carb counts and protein sources. We also studied patterns in user feedback to understand real-world mixing, taste, and digestive comfort.

The four criteria that carried the most weight were net carbs per serving, protein quality and bioavailability, and ingredient transparency. That means no hidden fillers or artificial sweeteners. We also looked at how well the product fits different keto lifestyles, whether for a meal replacement, post-workout shake, or collagen boost.

This is a research-led evaluation, not a hands-on test. We rely on verified data and aggregated owner experiences to identify the strongest options. If you have specific allergies or medical needs, we always recommend checking with your healthcare provider before adding a new supplement.

What To Look For In Protein Powders For Keto Diet

Choosing the right protein powder for keto means reading past the marketing and focusing on three key areas: net carbs, protein source, and ingredient quality.

Focus on net carbs (total carbs minus fiber and sugar alcohols), the protein source’s bioavailability, and whether the ingredient list includes hidden sugars, starches, or unnecessary fillers that could spike insulin.

Net Carbs Per Serving

The most critical number for keto is net carbs. Aim for powders with 3 grams or fewer per serving. Some products like the Isopure Zero Carb Whey Isolate Protein Powder go to zero, while others like the Orgain Organic Vegan Protein Powder have slightly more due to fiber. Watch out for “low carb” claims that hide maltodextrin or other high-glycemic fillers in the ingredient list.

Protein Source and Completeness

Whey isolate, casein, and collagen each affect ketosis differently. Whey isolate is fast-absorbing and nearly carb-free, making it ideal post-workout. Collagen powders like the Orgain Keto Collagen Protein Powder provide joint and skin benefits but are not complete proteins. Plant-based options like the Vega Protein + Creatine Plant Based Powder can work but often have slightly higher carb counts. Match the protein source to your daily needs and digestive tolerance.

Ingredient Transparency and Additives

Keto dieters should scrutinize the ingredient list for artificial sweeteners, sugar alcohols that cause digestive distress, and hidden starches. Products like the KetoLogic Keto Meal Replacement Shake and Ancient Nutrition Keto Protein Powder stand out for avoiding artificial flavors and sweeteners. Look for recognizable ingredients and third-party testing seals when available.

  • Check the net carb calculation yourself, manufacturers sometimes use creative math.
  • Look for protein powders that list the exact source (e.g., “100% whey isolate” vs. “protein blend”).
  • Avoid products with maltodextrin, corn syrup solids, or modified food starch.
  • Consider your digestive tolerance to sugar alcohols like erythritol or xylitol.

A good rule of thumb: if the ingredient list has more than 10 items, check each one against your keto goals.

Frequently Asked Questions

Can I use protein powder on keto without breaking ketosis?

Yes, as long as you choose a powder with very low net carbs, ideally 3 grams or less per serving. Pure whey isolates and collagen peptides are the safest bets. Always check the label for hidden sugars or starches.

What is the difference between whey isolate and collagen for keto?

Whey isolate is a complete protein with all essential amino acids, making it ideal for muscle repair and growth. Collagen is not a complete protein but supports skin, hair, and joint health. Many keto dieters use whey post-workout and collagen as a daily supplement.

How much protein powder should I use on a keto diet?

This depends on your individual protein needs, which vary based on factors like body weight and activity level. Most single servings provide 20–25 grams of protein. Use one to two scoops daily to fill gaps in your diet without exceeding your carb limit.

Are plant-based protein powders keto-friendly?

Some are, but you have to be careful. Plant proteins like pea and hemp often have higher carb counts than whey. The Vega Protein + Creatine Plant Based Powder and Orgain Organic Vegan Protein Powder are solid options with controlled net carbs. Always verify the label.

What should I avoid in a keto protein powder?

Avoid added sugars, maltodextrin, modified food starch, and high-glycemic fillers. Also watch for sugar alcohols like sorbitol or maltitol, which can cause digestive issues and have a higher glycemic impact than erythritol or stevia.

The Bottom Line

The Isopure Low Carb Whey Isolate Protein Powder is the best overall pick for keto dieters who want zero sugar, a pure protein source, and minimal ingredients. It’s ideal for anyone who prioritizes clean macros and doesn’t mind buying smaller bags more frequently.

If you need a complete protein blend with a steady amino acid release, the Quest Nutrition Peanut Butter Protein Powder delivers with only 2g net carbs per scoop. For vegans, the Orgain Organic Vegan Protein Powder offers organic plant protein with gut-friendly prebiotic fiber.

The single most important factor when choosing a keto protein powder is net carbs per serving. Get that right, and everything else, flavor, texture, protein source, becomes a matter of personal preference.
