【Product Overview】
L-Isoleucine, also known as L-2-Amino-3-methylvaleric acid, is an essential branched-chain amino acid (BCAA) that cannot be synthesized by the human body and must be obtained through diet. It is one of the three branched-chain amino acids, along with L-leucine and L-valine. L-Isoleucine plays a critical role in protein synthesis, energy metabolism, muscle recovery, immune function, and hemoglobin formation. As a glucogenic amino acid with slight ketogenic properties, it provides dual metabolic pathways for energy production.
Our food grade L-isoleucine is produced via advanced microbial fermentation using starch or sugar as raw materials, in full compliance with QB/T 5633.1-2021 industry standards. The final product appears as white crystalline small plates or crystalline powder with a slight bitter taste, odorless, excellent water solubility, and stable quality. It is suitable for food fortification, sports nutrition, special dietary foods, and various other applications.
【 Applications】
L-Isoleucine is one of the most widely used amino acid ingredients in the global food, beverage, and nutraceutical industries. It can be used alone or in combination with other BCAAs to achieve optimal nutritional profiles. Below are key application categories and recommended usage levels.
