L-Isoleucine is an essential branched-chain amino acid (BCAA) that the body cannot synthesize itself and therefore must be obtained through food. It has several important functions in the body:

Protein synthesis : L-isoleucine is one of the key building blocks for protein synthesis in the body. It is particularly important for building and repairing muscle tissue. Together with the other BCAAs (leucine and valine), it makes up about a third of muscle proteins.

Energy production : L-Isoleucine can serve as a fuel for energy production. During intense physical activity, muscles can rely on the BCAAs to generate energy and delay muscle fatigue.

Muscle metabolism : L-Isoleucine plays an important role in muscle metabolism. It may help reduce the breakdown of muscle protein during intense physical activity and promote protein synthesis, which contributes to muscle recovery and muscle building.

Blood sugar level regulation : L-isoleucine may also play a role in regulating blood sugar levels by improving insulin sensitivity. Insulin is a hormone that lowers blood sugar levels, and increased insulin sensitivity may help keep blood sugar levels stable.

Immune function : L-isoleucine can support immune system function by promoting the production of immune cells and antibodies. A strong immune system is important for fighting off diseases and infections.
