From weight loss to better blood sugar control to healthy aging, the benefits of protein are well established. While you can likely meet your protein needs through your diet, protein powders offer a convenient and easy way to increase your intake. Many people following low-carb or ketogenic diets turn to protein powders to supplement their diet.

Here are 5 best low carb  keto-friendly protein powders.

1. Whey Protein Isolate

Whey protein is one of two proteins derived from dairy.

Owing to its amino acid profile, whey protein is a high-quality source of protein that your body can digest and absorb quickly.

The two main types of whey protein are concentrate and isolate.

During the manufacturing process of whey protein powder, much of the lactose — or milk sugar — is filtered out, leaving a condensed product called whey protein concentrate.

Whey protein concentrate contains 35–80% protein by weight. For instance, a typical scoop of 80% whey protein by weight will contain about 25 grams of protein and 3–4 grams of carbs — and, if flavoring is added, possibly more.

Whey protein concentrate is then further processed and filtered to make an even more concentrated product called whey protein isolate, which boasts 90–95% protein by weight.

Whey protein isolates have the highest percentage of pure protein and the lowest number of carbs per serving of any whey protein.

For example, one scoop (31 grams) of this product by Isopure contains 0 carbs and 25 grams of protein, and one scoop (30 grams) of this product from NutraBio has just 1 gram of carbs and 25 grams of protein.

2. Casein Protein

Casein, the other milk protein, is also high in quality but digested and absorbed much more slowly by your body than whey.

This makes casein protein ideal for periods of fasting, such as before bed or between meals.

Like its whey counterpart, casein powder undergoes processing that extracts carbs and fat, leaving a concentrated source of protein.

Both Dymatize and NutraBio make a casein protein powder that provides only 2 grams of carbs and 25 grams of protein per 36-gram and 34-gram scoop, respectively.

Casein powders not only offer few carbs and generous amounts of protein but are a good source of calcium, an important mineral your body needs for bone health, muscle contractions and blood clotting.

For instance, the products from Dymatize and NutraBio boast 70% of the Daily Value (DV) for calcium per scoop.

Use more water to mix casein powder than you would with whey, as casein tends to thicken when stirred.

3. Egg Protein

Eggs are one of the most nutritious foods you can eat.

They’re packed with protein, essential vitamins and minerals and other important nutrients like choline, which is important for proper brain and nervous system functioning.

Egg-white protein powders are manufactured by removing the yolks and dehydrating the remaining egg whites, turning them into powder.

The egg whites are also pasteurized to deactivate avidin, a protein that inhibits the absorption of biotin, a crucial B vitamin.

Since egg whites naturally hold trivial amounts of carbs and fat, egg-white protein powders are a good option if you’re following a low-carb diet.

MRM makes a quality egg-white protein powder that provides 2 grams of carbs and 23 grams of protein — or the equivalent of six egg whites — per scoop (33 grams).

Some egg protein powders include both the white and yolk — which contains most of the important nutrients in eggs.

This egg-yolk protein powder from KetoThin boasts a good amount of fat — 15 grams — and a moderate amount of protein — 12 grams — with just 1 gram of carbs per scoop (30 grams), making it a perfect keto protein powder.

Egg-yolk protein powders do contain a relatively high amount of cholesterol, which was long thought to raise cholesterol levels in your body and contribute to heart disease.

However, research suggests that dietary cholesterol has little to no effect on blood cholesterol levels in most people. Thus, there is no significant link between the cholesterol you eat and your risk of heart disease.

4. Collagen Protein

Collagen is the most common structural protein in your body. It’s primarily found in your hair, skin, nails, bones, ligaments and tendons.

Collagen’s unique composition of amino acids gives it many purported health benefits, such as promoting body composition in older adults, as well as healthy skin and joints.

However, collagen lacks one of the essential amino acids that your body needs for good health. Because your body can’t make essential amino acids, it must get them from your diet.

Collagen protein powder, also called collagen peptides, is made from animal byproducts — usually cowhide, cow bones, chicken bones, eggshell membranes and fish scales.

Most available collagen protein powders are tasteless and unflavored, making them great to stir into soups or drinks like coffee.

What’s more, they’re naturally carb-free.

Vital Proteins makes a beef collagen product that contains 0 carbs and 17 grams of protein for every two scoops (20 grams), while Sports Research offers a similar product with 0 carbs and 10 grams of protein per scoop (11 grams).

Many flavored collagen protein powders are fortified with medium-chain triglycerides (MCTs), which are fats found in foods like coconut oil.

MCTs are easily digested and absorbed, providing your body with an alternative source of fuel — particularly when you severely restrict carbs, as with the keto diet.

For instance, one scoop (17 grams) of this product by Perfect Keto offers 1 gram of carbs, 10 grams of protein and 4 grams of fat from MCTs.

5. Soy Protein Isolate

Soybeans are a type of legume that’s naturally high in protein.

Soy protein powder is created by grinding soybeans into a meal and then into soy protein isolate, which consists of 90–95% protein by weight and is practically free of carbs.

Keep in mind that manufacturers sometimes add sugar and flavorings that can contribute unwanted carbs.

For example, this vanilla-flavored soy protein isolate product by NOW Sports holds 13 grams of carbs and 25 grams of protein per scoop (45 grams).

A better option is this unflavored product by the same company, which has 0 carbs and 20 grams of protein per scoop (24 grams).
