Isoleucine
Isoleucine is an essential branched-chain amino acid (BCAA) that plays a crucial role in muscle metabolism, energy production, and immune function.

Origin of Ingredient
Isoleucine is one of the three branched-chain amino acids, found abundantly in protein-rich foods such as meat, fish, eggs, dairy products, and legumes. It is classified as an essential amino acid, meaning the body cannot synthesize it, and it must be obtained through diet or supplementation.
History of Ingredient
The importance of isoleucine, along with other BCAAs, was recognized in the early 20th century when researchers began to understand the role of amino acids in protein synthesis and muscle metabolism. Athletes and bodybuilders have since utilized isoleucine supplements to enhance muscle recovery and performance, making it a staple in sports nutrition.
Scientific Makeup of Ingredient
Isoleucine is a branched-chain amino acid with a unique structure that allows it to be directly metabolized in muscle tissue. This property makes it particularly important for muscle recovery and energy production during exercise. Isoleucine also plays a role in hemoglobin synthesis and the regulation of blood sugar levels.
Studies have shown that isoleucine, along with leucine and valine, supports muscle protein synthesis and reduces muscle breakdown during and after exercise. Research indicates that isoleucine supplementation can improve endurance, enhance muscle recovery, and reduce exercise-induced muscle soreness. Additionally, isoleucine has been found to support immune function and assist in the regulation of energy metabolism.
Isoleucine is widely approved for use in dietary supplements and sports nutrition products in many countries, including the United States, the European Union, and various other regions. Legal claims about isoleucine include its benefits for muscle recovery, energy production, and immune support. Always ensure compliance with local regulatory guidelines when making specific health claims.
Health claims on food supplements in the UK and EU must be authorised, and our technical and quality team checks label wording for compliance before a label is approved.
