L-Isoleucine is one of three branched chain amino acids (BCAAs), the other two being L-leucine and L-valine. These BCAAs are found in proteins of all forms of life. They can be obtained in the diet through animal and vegetable sources. L-Isoleucine is important in hemoglobulin synthesis and in the regulation of blood sugar and energy levels. It also increases endurace.
L-Isoleucine is an isomer of Leucine. L-Isoleucine is metabolized in muscle tissue. Rich sources of L-isoleucine include cashews, almonds, and soy protein. L-Isoleucine is popular among athletes. It is typically taken or used with the other two BCAAs, L-leucine and L-valine.
