L-Isoleucine is one of the essential amino acids that the human body cannot synthesize on its own and belongs to the branched-chain amino acids with branched side chains. L-Isoleucine is not only a 'building block' for constructing muscle proteins, but also an important energy substrate and blood sugar regulation auxiliary factor during exercise. As one of the nine essential amino acids that must be obtained from food, L-Isoleucine, due to its unique molecular structure, has significant value in both physiological functions and applications.
Core Application Areas
Food Industry
Special dietary products
In infant formula, isoleucine serves as a key essential amino acid supporting nervous system and muscle development. In nutritional powders for the elderly, it helps prevent sarcopenia and supports improved mobility.
Seasonings and prepared foods
Used as a flavor-enhancing component added to soy sauce, hot pot bases, and similar products to enrich umami depth and mask undesirable odors. In ready-to-eat meals, it improves meat tenderness and can extend refrigerated shelf life by 2–3 days.
Baked goods
Added to bread and biscuits to improve dough extensibility, delay starch retrogradation (extending shelf life by 3–5 days), and enhance softness and overall texture of finished products.
Sports Nutrition
BCAA compound supplements
As the "core amino acid for energy supply" within the BCAA group, it is commonly used in blends with typical ratios of leucine : isoleucine : valine = 2:1:1 or 3:1:1. Intra-workout intake helps rapidly replenish energy and reduce muscle breakdown.
Fortified fitness foods
Added to protein bars and sports beverages for endurance activities such as marathons or strength training. It helps alleviate central nervous system fatigue and delays the onset of exercise-induced exhaustion.
Feed Industry
Livestock and poultry feed
In weaning piglet feed, isoleucine reduces stress-related declines in feed intake and improves survival rates. In broiler chicken finishing feed, it enhances feed conversion efficiency and increases breast muscle yield.
Aquaculture feed
In fish and shrimp nursery feed, it improves stress resistance and reduces mortality, suitable for high-value species such as bass and Litopenaeus vannamei (whiteleg shrimp).
Pet food
Added to senior dog and cat food to reduce age-related muscle loss and improve mobility. In postoperative pet canned food, supplementation at 0.4%–0.6% promotes wound healing.
