What is Isoleucine?

Isoleucine is one of the essential amino acids, meaning the body cannot produce it and it must be obtained through the diet. It is crucial for muscle protein synthesis, energy production, and maintaining proper immune function. Isoleucine also plays a significant role in hemoglobin production and regulating blood sugar levels.

Benefits of Isoleucine

  • Muscle Protein Synthesis: Essential for building and repairing muscle tissue.

  • Energy Production: Helps in the production of energy and the regulation of blood sugar levels.

  • Immune Function: Supports the immune system and aids in the healing of wounds.

  • Hemoglobin Production: Important for the production of hemoglobin, which carries oxygen in the blood.

Daily Recommended Value (DRV) for Isoleucine

The DRV for Isoleucine is approximately 19 mg per kilogram of body weight per day. For an average adult weighing 70 kg, the daily requirement would be:
