100% CASEIN FUSION gives you 25 grams of slow-digesting protein per serving, and it includes 5.5 grams of BCAAs and 5 grams of Glutamine, the most abundant amino acid in muscle tissue. Micellar casein and milk protein concentrate are digested slowly, allowing them to trickle feed your muscles for extended periods. Micellar casein can release muscle-building amino acids into your bloodstream for up to seven hours after consumption, and that’s why it’s the main protein source in 100% CASEIN FUSION
