L-Isoleucine is an essential BCAA (branched chain amino acid). Isoleucine ( abbreviated as Ile or I ) is an α – amino acid with the chemical formula HO2CCH(NH2)CH(CH3)CH2CH3.  With a hydrocarbon side chain, isoleucine is classified as a hydrophobic amino acid. Together with threonine, isoleucine is one of two common amino acids that have a chiral side chain. Four stereoisomers of isoleucine are possible, including two possible diastereomers of L-isoleucine. However, isoleucine present in nature exists in one enantiomeric form, (2S,3S)-2-amino-3-methylpentanoic acid.It is an essential amino acid, which means that humans cannot synthesize it, so it must be ingested. Foods which have high content of L-isoleucine include nuts and seeds, meat, legumes, eggs, peas, soy products, brown rice, and whole wheat, among others. L-isoleucine in the body is generally found in its highest concentrations in the muscles.

L-Isoleucine Benefits

L-isoleucine levels will be lowest right after exercise and will need to be recovered. Supplementation of L-isoleucine one hour before exercise may help aid recovery. L-isoleucine may also help maintain endurance and promote muscle growth when taken in conjunction with exercise.
