USP labs introduces the new and improved modern BCAA plus ultra micronized amino acid supplement. Contains the coveted 8:1:1 BCAA ratio plus the addition for these key aminos glycine, alanine, taurine and lysine. Supplementing with this amino around exercise is very important because muscles release more glycine during fasted exercise than any other amino, which creates a catabolic state. Alanine is also released at very high rates during fasted exercise, making supplementation important to preventing a catabolic state. Taurine is the most abundant amino acid in skeletal muscle. A recent animal study demonstrated that when muscles are low in taurine, muscle function and performance were significantly reduced. Lysine is an essential amino acid that has been shown to preserve leucine in a protein starved state.
