Product Basic Information & Chemical Specifications
Our L-Isoleucine powder supports three core physiological pathways for human and animal metabolism:
1. Protein Metabolism Support As direct substrate for intracellular protein synthesis, L-Isoleucine inhibits skeletal muscle protein breakdown, regulates amino acid transportation, and maintains whole-body nitrogen balance. Widely used in post-workout recovery formulas and postoperative nutritional preparations.
2. Hepatic Gluconeogenesis During long-term exercise, fasting or metabolic imbalance, L-Isoleucine transforms into tricarboxylic acid cycle intermediates in the liver to generate glucose and supply sustained energy for the body.
3. Multi-dimensional Physiological Regulation
- Promotes hemoglobin synthesis and stabilizes blood glucose by improving insulin sensitivity
- Stimulates proliferation and differentiation of immune cells to strengthen immune defense
- Acts as precursor of multiple bioactive substances to accelerate tissue repair and cell regeneration
