PEScience Select Protein Review

Select Protein is presented as the protein powder that started the PEScience line, a premium whey and casein blend designed for sustained amino acid release and superior digestion. The page says milk protein isolate is the number one ingredient, which the company describes as a rare choice due to its higher cost, and says this brings naturally low lactose content, strong digestibility, and a creamier texture. The listed benefits include a whey plus casein blend that the page says is more effective than 100% whey alone for muscle protein synthesis, milk protein isolate as the first ingredient with very low lactose, third-party testing for quality and purity, a low carb and gluten free formulation, and flavors developed in-house to taste true to name. The product is offered in more than ten flavors including Frosted Sugar Cookie, Chocolate Truffle, Cake Pop, Gourmet Vanilla, Snickerdoodle, Chocolate Peanut Butter Cup, Frosted Chocolate Cupcake, Cookies N Cream, Peanut Butter Cookie, Strawberry Cheesecake, Island Cookie, Unflavored, and a seasonal White Chocolate Macadamia. Sizes range from a 1 sample and 5 serving trial and travel bag up to a 55 serving bulk tub, with 27 servings listed for a main size. The nutrition panel lists a serving size of one scoop (32g) with 110 calories, 24g protein, 2g total carbohydrate, 1g total fat, 45mg cholesterol, 290mg sodium, and 265mg calcium. The page notes about 0.5g of lactose per serving, compared with 13g in a cup of milk. Certificates of Assurance are shown for several flavors, and the company says all finished products and ingredients are third-party tested, a practice in place since its founding in 2010. The page shows a price of $49.99 with a listed cost of $1.85 per serving, and also offers an Amazon listing and a subscription purchase option. The allergen statement reads contains milk and soy lecithin ingredients. The page closes by describing the product as the protein you will actually crave.

RAL Summary

MembersThe tier and why

Its studied ingredients are at the doses that in studies, and reviews are on their own. The final check notes: The tier was set from trace nutrients (vitamin D, potassium, calcium and iron) instead of the main ingredient, the milk and whey protein blend, and protein evidence was given, so the evidence for this goal is thin.
