Combines 25g Protein and 10g Collagen ---- By combining lactose-free milk protein isolate with collagen peptides, Vital Performance Protein Powder delivers 25g of complete protein designed to complement your fitness routine.

Why We Can Say 'Lactose-Free' ---- The process of milk → milk protein concentrate → milk protein isolate → lactase enzyme helps to further reduce the lactose content. Excellent supplement for lactose-intolerant and active lifestyle consumers, looking to boost their daily intake of complete, high-quality protein and collagen.

What It Does ---- Dairy proteins are high-quality proteins, due to their EAA content and digestibility. Our milk protein isolate delivers the same casein to whey ratio (80:20) as milk. It provides a robust amino acid profile to support muscle protein synthesis and improved recovery.**

Core ISO, we have developed the purest, highest-quality, least-adulterated WPI product on the market. We have taken the highest purity, non-instantiated, non-soy, non-GMO whey protein isolate available, and essentially added nothing to it: we have added no sugars, making it the perfect versatile protein; and we have added no artificial colors, meaning you can feel good about drinking it.

Core ISO has an optimal amino acid profile with a high amount of BCAAs, and in particular leucine, to counteract the rate of leucine oxidation that occurs as the fractional rate of protein synthesis decreases, and the rate of muscle protein degradation increases.

The studies have proven, “the ingestion of isolated whey protein supports greater rates of MPS than micellar casein both at rest and after resistance exercise in healthy elderly men. This result is probably related to a greater hyperaminoacidaemia or leucinaemia with whey ingestion.”
