L-Leucine (instantized, Ultra-Soluble)
Because it digests and assimilates into your body more quickly than the other BCAAs, leucine is the most important necessary amino acid. Leucine will then be utilised by your body more quickly than valine and isoleucine. By producing B-hydroxy-B-methyl butyrate, it supports healthy muscle fibres (HMB). Thus, it causes a favourable reaction in your muscles, promoting their growth.
