Which Protein Powder is Right For Me?

Why Whey Protein?

Whey Protein is one of two proteins derived from cow’s milk; the other is casein. The proteins in whey are alpha-lactalbumin, beta-lactoglobulin, serum albumin, lactoferrin and immunoglobulins (antibodies). Whey protein is a complete protein, because it has the nine essential amino acids which help with protein synthesis, contributing to the growth of lean muscle1. Whey protein, especially whey isolate, is easily digestible and is nearly lactose free, making it a great option for those who have a lactose sensitivity or intolerance.*

Benefits of Whey Protein

  • Studies show that whey protein can promote weight loss.2
  • Whey has been shown to lower cholesterol.3
  • Whey protein may help decrease blood pressure and risk of heart disease.4
  • Whey protein has been shown to build muscle better than other types of protein.5

*choose a non-whey protein if you are allergic to lactose

Different Types of Whey Protein

  • Whey Protein Concentrate: Made of about 80% protein, it can be harder to digest than whey protein isolate.
  • Whey Protein Isolate: Non-protein components have been removed and contains 90% protein by volume, easier to digest than casein protein or whey concentrate, with low lactose levels.
  • Whey Protein Hydrolysate: Its enzymes have broken up its amino acids, also called hydrolyzed into short peptides in order to be easily digested. It tastes more bitter than whey concentrate and isolate and is often used in infant formula.


Why Casein Protein?

Casein, derived from cow’s milk, is a phosphoprotein that contains all nine essential amino acids. One of the most attractive properties of casein as a supplement is that it is slower to digest than whey protein. This allows for a longer lasting feeling of satiety, which in turns help curb cravings.6

Benefits of Casein Protein

  • Casein digests slowly to keep you full longer.
  • Studies show casein to result in the largest whole-body protein gain.7
  • Casein contains calcium which has been shown to promote fat loss.8

Types of Protein In Our Products

BariNutrition Protein Powders contain a signature blend of whey protein isolate and casein.

  • Whey Protein Isolate is 90% pure protein by volume, meaning less fat and carbohydrates than in whey concentrate.
  • Whey protein isolate is quickly digestible which makes it ideal for consuming after a workout, while casein promotes feeling full longer.
  • Studies show that adding casein protein to a whey supplement blend contributes to greater lean muscle gains than consuming a whey supplement alone.9
