Most protein powders are already low in carbohydrates; however, there are also many more protein powders made from foods that naturally contain carbohydrates. So the powders may contain a blend that includes carbohydrates.
While you can achieve your protein needs with just food, protein powders offer a convenient and easy way to increase your intake while also being low in calories and unnecessary carbs. If you're on a low-carb or ketogenic diet, you may be looking for protein powders to supplement your diet.
Choosing a high-quality protein supplement to fit your low-carb or keto lifestyle can be particularly challenging, as there are many variations and sources of protein powder. To make things easier, we have found the best protein powders to fit a low-carbohydrate diet, with most also being keto-friendly.

What is Low-Carb Protein Powder?
When it comes to low-carb or keto diet protein powders, there are a handful of forms that they can come in. The most common type is whey protein isolate, which is the purest kind of whey protein you can buy.
1. Whey Protein Isolate
Whey protein isolate contains the highest percentage of protein while having the lowest number of carbs per serving of any whey protein. It typically contains few, if any, carbohydrates per scoop.
2. Casein
Casein is another common milk protein that is low-carb and has a generous amount of protein. Casein is digested and absorbed much slower than whey, making it a popular choice for overnight recovery or prolonged periods without a meal.
3. Egg
While unconventional egg-based protein powders are starting to grow in popularity as they are pure protein and usually contain zero carbs. Egg white protein powders are commonly manufactured by removing the yolks and then dehydrating the remaining whites to create a powder.
The egg whites are then pasteurized to deactivate avidin, a protein that inhibits the absorption of an essential B vitamin. The actual nutrient values for things like cholesterol and protein will vary depending on the type of egg protein powder you choose.
4. Collagen
Collagen protein powder, also known as collagen peptides, accounts for 30% of your body's protein and provides structure, support, or strength to your skin, muscles, bones, and connective tissues. Collagen has a unique set of amino acids compared to a typical animal or plant-based protein powder and is often made from animal sources, like bovine.
Collagen can be more effective than whey in injury recovery and rebuilding connective tissues and other structures in the body.
5. Plant
Many manufacturers provide plant-based alternatives to standard protein powders to accommodate different dietary restrictions and lifestyles. Plant-based protein powders are often derived from various plants, with the most common being brown rice, pea, soy, and hemp.
Depending on the brand, a plant-based protein powder may be made from only one type of plant or a combination of plant sources.

Benefits of Low-Carb Protein Powder:
While protein powder is not a miracle supplement, if you stay consistent with your protein intake and workout regimen, you will see fantastic results in as little as a few weeks. Let's break down the benefits of low-carb protein powder and what it can bring to your fitness journey.
1. Build Muscle
Protein is one of the most essential nutrients supporting muscle growth as it plays a significant role in rebuilding and recovering muscles. The protein you get from whole foods and supplements is the most crucial macronutrient for promoting muscle growth. It stimulates protein synthesis, builds new muscle, and prevents the body from absorbing existing muscle.
In fact, a research study concluded that total daily protein intake is the most crucial variable in gains in muscle size during resistance training.¹
2. Keto Friendly
Eating adequate amounts of protein powder is incredibly beneficial on the ketogenic diet as it can help your body stay in an anabolic state, have fewer calories and carbs, and improve your health.
A randomized controlled trial found that in the short term, a high protein, low carb keto diet can reduce hunger and lower food intake significantly more than a high protein, medium carbohydrate diet.² So supplementing with a low-carb, high-protein powder is Keto-friendly and won't affect your diet.
3. Boosts metabolism
Once you begin losing weight and are in a calorie deficit, maintaining high protein levels stimulates your body into thinking that you are fasting. This low-carb/low-calorie diet means your body switches from metabolizing carbohydrates for quick energy to metabolizing fat.
This leaves your body looking leaner and more toned as a result. Studies have shown that individuals on a high-protein diet saw a more significant metabolism than others that were on a diet including moderate carbohydrates and protein.³
If you cut calories, you can trust that you will lose weight. However, taking a low-carb protein powder provides greater benefits in weight loss by boosting your overall metabolism.
4. Helps burn fat
A low-calorie diet with low carbs and high protein plus an exercise program will help individuals with excess belly fat lose even more weight, especially by supplementing low-cal/low-carb protein powders in the diet. These protein powders stimulate muscle protein synthesis, reducing muscle loss and lowering insulin in the blood so that more fat is burned overall.
Recent evidence supports higher-protein diets as a successful strategy to prevent or treat obesity by improving the body's ability to burn fat.?
Low-Carb Protein Powder Side Effects
Protein supplements can be beneficial in supplementing your diet and hitting your daily protein goals. Protein is considered the building block of life and helps to repair muscles, recover after workouts, and coordinate many body functions.
However, excess intake of protein supplements can cause some unwanted side effects. Overconsumption of protein supplements can cause increased bowel movements, bloating, flatulence, diarrhea, and even weight gain.
In rare cases, it has also been reported to lower blood pressure too much, affect the kidneys, and negate certain medicines and drugs. We recommend taking protein supplements based on the recommended serving and limiting quantities to avoid adverse reactions.

What to look for when buying Low-Carb Protein Powder:
Low-carb protein powder supplements should be manufactured with the highest quality ingredients, be third-party tested, have great reviews, and contain minimum carbohydrates. As a team, we have reviewed the best low-carb protein options on the market by evaluating them for these factors.
Below is a breakdown of how we reviewed low-carb protein powders and what to look for when picking one out for yourself.
1. Ingredients
One of the most important factors when researching protein supplements is ensuring that the primary ingredients are pure. There are many kinds of protein powders, all made with different types of protein.
We recommend choosing a protein powder made with a protein source that fits your preferences and dietary restrictions. If you're following a keto or low-carb diet, total carbohydrate intake should be kept under a certain amount based on the diet you're following and is essential to track.
Most protein powders have less than 10 grams of carbs per serving, with low-carb options usually having less than five grams. We recommend looking for a protein powder with minimal or no added sugars to reduce carbohydrate intake significantly.
2. Testing/Transparency
The safety and testing of a company's supplements should be one of the most important factors when choosing a protein powder supplement. As such, we have created the list above with brands that have repeatedly proven themselves to develop high-quality products with the best ingredients and manufacturing processes.
When researching low-carb protein powders, you want to avoid options that hide their ingredients behind an unclear proprietary blend. Another great way of knowing if a supplement is high quality and has pure ingredients is if it is third-party tested. It guarantees it's adequately dosed, prevents impurities, and is exactly what the label describes.
3. Price
Protein powder costs can vary widely, depending on the quality, manufacturing, and other factors that can drive the price up or down. We recommend breaking down the cost per serving when choosing the best option.
This will also ensure that you choose a financially sustainable protein powder. For most people, the more reasonable the price, the longer you are likely to take it.
Typically low-carb protein powders with high-quality materials, adequately dosed, third-party tested, come from a reputable brand, and have great reviews range in the 35-60 dollar range. The biggest factor determining price is how many servings are in each container.
4. Reviews
When buying any low-carb protein powder, one of the best ways of verifying a supplement's legitimacy is by checking out customer reviews. We recommend checking out the brand's review section, where previous customers share their positive or negative experiences with the product.
Low-Carb Protein Powder FAQs
Is low-carb protein powder good for you?
Low-carb protein powder is an excellent choice for individuals on a low-carb diet or a lower-calorie protein option. If you do experience side effects, consult your doctor.
Do low-carb protein shakes help you lose weight?
Protein shakes are a quick and easy way to introduce more protein to your diet and have been shown to aid weight loss. This is because protein is essential for promoting weight loss, as getting enough protein supports healthy metabolism and reduces appetite.
Can low-carb, high-protein build muscle?
A high protein, low carb diet has become quite popular to encourage weight loss while maintaining and even increasing muscle mass.
What happens if you take protein powder every day?
Taking protein powder daily is okay, but we recommend obtaining most of your protein from whole food sources. You'll miss out on other essential nutrients if you miss out on eating complete food sources.
We recommend not taking more than one or two servings of protein powder daily.

Summary
Protein powders are a simple and versatile way to supplement your diet. While many protein options are inherently low in carbs, not all protein powders are the same. Some manufacturers often add sugar or other ingredients to improve flavor and sweetness, which can increase total carbohydrates and calories.
You can avoid these kinds of powders by choosing from the protein powders on this list and picking the one that fits your needs. All the options on this list are high quality and optimized to benefit your low-carb or keto diet based on your goals and needs.

What is Low-Carb Protein Powder?
When it comes to low-carb or keto diet protein powders, there are a handful of forms that they can come in. The most common type is whey protein isolate, which is the purest kind of whey protein you can buy.


1. Whey Protein Isolate
Whey protein isolate contains the highest percentage of protein while having the lowest number of carbs per serving of any whey protein. It typically contains few, if any, carbohydrates per scoop.


2. Casein
Casein is another common milk protein that is low-carb and has a generous amount of protein. Casein is digested and absorbed much slower than whey, making it a popular choice for overnight recovery or prolonged periods without a meal.


3. Egg
While unconventional egg-based protein powders are starting to grow in popularity as they are pure protein and usually contain zero carbs. Egg white protein powders are commonly manufactured by removing the yolks and then dehydrating the remaining whites to create a powder.


The egg whites are then pasteurized to deactivate avidin, a protein that inhibits the absorption of an essential B vitamin. The actual nutrient values for things like cholesterol and protein will vary depending on the type of egg protein powder you choose.


4. Collagen
Collagen protein powder, also known as collagen peptides, accounts for 30% of your body's protein and provides structure, support, or strength to your skin, muscles, bones, and connective tissues. Collagen has a unique set of amino acids compared to a typical animal or plant-based protein powder and is often made from animal sources, like bovine.


Collagen can be more effective than whey in injury recovery and rebuilding connective tissues and other structures in the body.


5. Plant
Many manufacturers provide plant-based alternatives to standard protein powders to accommodate different dietary restrictions and lifestyles. Plant-based protein powders are often derived from various plants, with the most common being brown rice, pea, soy, and hemp.


Depending on the brand, a plant-based protein powder may be made from only one type of plant or a combination of plant sources.





Benefits of Low-Carb Protein Powder:
While protein powder is not a miracle supplement, if you stay consistent with your protein intake and workout regimen, you will see fantastic results in as little as a few weeks. Let's break down the benefits of low-carb protein powder and what it can bring to your fitness journey.


1. Build Muscle
Protein is one of the most essential nutrients supporting muscle growth as it plays a significant role in rebuilding and recovering muscles. The protein you get from whole foods and supplements is the most crucial macronutrient for promoting muscle growth. It stimulates protein synthesis, builds new muscle, and prevents the body from absorbing existing muscle.


In fact, a research study concluded that total daily protein intake is the most crucial variable in gains in muscle size during resistance training.¹


2. Keto Friendly
Eating adequate amounts of protein powder is incredibly beneficial on the ketogenic diet as it can help your body stay in an anabolic state, have fewer calories and carbs, and improve your health.


A randomized controlled trial found that in the short term, a high protein, low carb keto diet can reduce hunger and lower food intake significantly more than a high protein, medium carbohydrate diet.² So supplementing with a low-carb, high-protein powder is Keto-friendly and won't affect your diet.


3. Boosts metabolism
Once you begin losing weight and are in a calorie deficit, maintaining high protein levels stimulates your body into thinking that you are fasting. This low-carb/low-calorie diet means your body switches from metabolizing carbohydrates for quick energy to metabolizing fat.


This leaves your body looking leaner and more toned as a result. Studies have shown that individuals on a high-protein diet saw a more significant metabolism than others that were on a diet including moderate carbohydrates and protein.³


If you cut calories, you can trust that you will lose weight. However, taking a low-carb protein powder provides greater benefits in weight loss by boosting your overall metabolism.


4. Helps burn fat
A low-calorie diet with low carbs and high protein plus an exercise program will help individuals with excess belly fat lose even more weight, especially by supplementing low-cal/low-carb protein powders in the diet. These protein powders stimulate muscle protein synthesis, reducing muscle loss and lowering insulin in the blood so that more fat is burned overall.


Recent evidence supports higher-protein diets as a successful strategy to prevent or treat obesity by improving the body's ability to burn fat.?


Low-Carb Protein Powder Side Effects
Protein supplements can be beneficial in supplementing your diet and hitting your daily protein goals. Protein is considered the building block of life and helps to repair muscles, recover after workouts, and coordinate many body functions.


However, excess intake of protein supplements can cause some unwanted side effects. Overconsumption of protein supplements can cause increased bowel movements, bloating, flatulence, diarrhea, and even weight gain.


In rare cases, it has also been reported to lower blood pressure too much, affect the kidneys, and negate certain medicines and drugs. We recommend taking protein supplements based on the recommended serving and limiting quantities to avoid adverse reactions.





What to look for when buying Low-Carb Protein Powder:
Low-carb protein powder supplements should be manufactured with the highest quality ingredients, be third-party tested, have great reviews, and contain minimum carbohydrates. As a team, we have reviewed the best low-carb protein options on the market by evaluating them for these factors.


Below is a breakdown of how we reviewed low-carb protein powders and what to look for when picking one out for yourself.


1. Ingredients
One of the most important factors when researching protein supplements is ensuring that the primary ingredients are pure. There are many kinds of protein powders, all made with different types of protein.


We recommend choosing a protein powder made with a protein source that fits your preferences and dietary restrictions. If you're following a keto or low-carb diet, total carbohydrate intake should be kept under a certain amount based on the diet you're following and is essential to track.


Most protein powders have less than 10 grams of carbs per serving, with low-carb options usually having less than five grams. We recommend looking for a protein powder with minimal or no added sugars to reduce carbohydrate intake significantly.


2. Testing/Transparency
The safety and testing of a company's supplements should be one of the most important factors when choosing a protein powder supplement. As such, we have created the list above with brands that have repeatedly proven themselves to develop high-quality products with the best ingredients and manufacturing processes.


When researching low-carb protein powders, you want to avoid options that hide their ingredients behind an unclear proprietary blend. Another great way of knowing if a supplement is high quality and has pure ingredients is if it is third-party tested. It guarantees it's adequately dosed, prevents impurities, and is exactly what the label describes.


3. Price
Protein powder costs can vary widely, depending on the quality, manufacturing, and other factors that can drive the price up or down. We recommend breaking down the cost per serving when choosing the best option.


This will also ensure that you choose a financially sustainable protein powder. For most people, the more reasonable the price, the longer you are likely to take it.


Typically low-carb protein powders with high-quality materials, adequately dosed, third-party tested, come from a reputable brand, and have great reviews range in the 35-60 dollar range. The biggest factor determining price is how many servings are in each container.


4. Reviews
When buying any low-carb protein powder, one of the best ways of verifying a supplement's legitimacy is by checking out customer reviews. We recommend checking out the brand's review section, where previous customers share their positive or negative experiences with the product.


Low-Carb Protein Powder FAQs
Is low-carb protein powder good for you?
Low-carb protein powder is an excellent choice for individuals on a low-carb diet or a lower-calorie protein option. If you do experience side effects, consult your doctor.


Do low-carb protein shakes help you lose weight?
Protein shakes are a quick and easy way to introduce more protein to your diet and have been shown to aid weight loss. This is because protein is essential for promoting weight loss, as getting enough protein supports healthy metabolism and reduces appetite.


Can low-carb, high-protein build muscle?
A high protein, low carb diet has become quite popular to encourage weight loss while maintaining and even increasing muscle mass.


What happens if you take protein powder every day?
Taking protein powder daily is okay, but we recommend obtaining most of your protein from whole food sources. You'll miss out on other essential nutrients if you miss out on eating complete food sources.


We recommend not taking more than one or two servings of protein powder daily.





Summary
Protein powders are a simple and versatile way to supplement your diet. While many protein options are inherently low in carbs, not all protein powders are the same. Some manufacturers often add sugar or other ingredients to improve flavor and sweetness, which can increase total carbohydrates and calories.


You can avoid these kinds of powders by choosing from the protein powders on this list and picking the one that fits your needs. All the options on this list are high quality and optimized to benefit your low-carb or keto diet based on your goals and needs.
