Food Grade 99% L-Isoleucine Powder Manufacturer
L-Isoleucine: Product Introduction
YTBIO 99% L-Isoleucine is one of our flagship products. This product is a white crystalline powder with good flowability. L-Isoleucine belongs to the branched-chain amino acid (BCAA) family and is one of the nine essential amino acids that the human body cannot synthesize on its own. It is mainly found in muscle tissue and participates in multiple physiological processes such as protein synthesis, energy supply, and blood sugar stability. It can be widely used in clinical nutrition and sports nutrition products.

Product Features and Benefits
1. Supports Muscle Growth and Recovery
Isoleucine participates in the synthesis of muscle protein and helps reduce protein breakdown after exercise. Supplementing with relevant sports nutrition products can help muscle recovery and reduce soreness after training.
2. Participates in Blood Sugar Regulation
Isoleucine can be converted into glucose precursors or ketone bodies during metabolism. When the body's energy is insufficient, it helps maintain stable blood sugar levels. Some studies show that appropriate isoleucine supplementation has a certain promoting effect on insulin secretion.
3. Supports Immune Function
Isoleucine participates in the synthesis of glutamine, an important energy source for intestinal cells, which is directly related to maintaining intestinal health and immune function.
4. Improves Related Neurological Symptoms
Aromatic amino acids in patients with hepatic encephalopathy easily enter the brain, affecting neurological function. Branched-chain amino acids (including isoleucine) are mainly metabolized in muscles and can competitively reduce the entry of aromatic amino acids into the brain. Therefore, high levels of branched-chain amino acids have application value in the treatment of liver disease.
5. Effects on Metabolism and Lifespan
A study published in *Cell Metabolism* divided 9-week-old male and female mice into three groups, feeding them a normal amino acid diet, a low amino acid diet, and a low isoleucine diet, respectively, with the same caloric intake for all three groups. The results showed that mice in the low isoleucine group had a significantly lower initial body weight and improved glucose tolerance after 3 weeks. Male mice on a long-term low isoleucine diet starting at 6 months of age had a median lifespan increased by 33% and a significantly reduced frailty index. Studies have shown that restricting isoleucine intake helps improve metabolic health and extend lifespan, with male mice showing more significant benefits, indicating a direct link between isoleucine and metabolic health.
Application Areas
Pharmaceuticals
L-Isoleucine is mainly used in compound amino acid injections, nutritional support for patients with hepatic encephalopathy, and parenteral nutrition for postoperative, trauma, and critically ill patients.
Sports Nutrition
L-Isoleucine, as a core ingredient in branched-chain amino acid (BCAA) supplements, is commonly used in recovery products after exercise and training.
Food Industry
It is often used as a nutritional fortifier to enhance the amino acid composition of beverages and foods, or in functional foods for specific populations (such as those in recovery or the elderly).
Feed Additives
L-Isoleucine is often added to livestock and poultry feed to balance amino acid ratios, improve protein utilization, and promote animal growth.
