Some egg protein powders include both the white and yolk - which contains most of the important nutrients in eggs. 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). 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.
The egg whites are also pasteurized to deactivate avidin, a protein that inhibits the absorption of biotin, a crucial B vitamin ( 15). 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 ( 14).Įgg-white protein powders are manufactured by removing the yolks and dehydrating the remaining egg whites, turning them into powder. Protein powder made fromĬasein provides few carbs and a good amount of calcium.Įggs are one of the most nutritious foods you can eat ( 12, 13).
Is a milk protein that your body digests slowly. Use more water to mix casein powder than you would with whey, as casein tends to thicken when stirred. Like its whey counterpart, casein powder undergoes processing that extracts carbs and fat, leaving a concentrated source of protein ( 10).īoth 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.Ĭasein 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 ( 11).įor instance, the products from Dymatize and NutraBio boast 70% of the Daily Value (DV) for calcium per scoop. This makes casein protein ideal for periods of fasting, such as before bed or between meals ( 6, 7, 8, 9). or even zero - carbohydrates per scoop.Ĭasein, the other milk protein, is also high in quality but digested and absorbed much more slowly by your body than whey ( 4, 5). Protein isolate is the purest form of whey protein you can buy. Whey protein isolates have the highest percentage of pure protein and the lowest number of carbs per serving of any whey protein.įor 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. 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 ( 3). 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 ( 2). Whey protein concentrate contains 35–80% protein by weight.
The two main types of whey protein are concentrate and isolate.ĭuring 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.
Owing to its amino acid profile, whey protein is a high-quality source of protein that your body can digest and absorb quickly ( 1). Whey protein is one of two proteins derived from dairy.
