Isoleucine is used by the body in particular to build muscle tissue. Isoleucine, leucine and valine are branched-chain amino acids and are best absorbed and used by the body in the presence of B vitamins, such as beans or soy lecithin.
Dietary supplements rich in isoleucine, leucine and valine are also rich in vitamin B, so they improve absorption and use by the body, favoring muscle growth.
The main foods rich in isoleucine are
Isoleucine is an essential amino acid and therefore dietary sources of this amino acid are important because the body cannot produce it.
The recommended daily dose of isoleucine is approximately 1. 3 g per day for a 70 kg person, for example.
The main functions of the amino acid isoleucine are: increase the formation of hemoglobin; prevents the kidney from losing vitamin B3 or niacin and helps regulate blood sugar.
Lack of isoleucine can cause muscle fatigue and should therefore be ingested after physical exercise for muscle recovery.
