Isoleucine

Isoleucine is a branched chain amino acid that is important for blood sugar regulation, muscle development and repair, haemoglobin development, and energy regulation. Deficiencies of isoleucine result in possible dizziness, headaches, fatigue, depression, confusion and irritability. Isoleucine is found in eggs, fish, lentils, poultry, beef, seeds, soy, wheat, almonds and dairy.
