Product Detail

Usage:

L-Isoleucine (Abbreviated Iso) is one of the 18 common amino acids, and one of the eight essential amino acids at the human body. It is called branched chain amino acids (BCAA) with L-Leucine and L-Valine together because they all contain a methyl side chain in their molecular structure.

L-Isoleucine is one of the essential amino acids that cannot be made by the body and is known for its ability to help endurance and assist in the repair and rebuilding of muscle. This amino acid is important to body builders as it helps boost energy and helps the body recover from training.

The effects of L-Isoleucine include muscle repair with leucine and valine, controlling blood glucose, and providing body tissue with energy. It also improves the output of growth hormone and help to burn the visceral fat. This fat is within body interior and can’t be effectively digested only through diet and exercise.

L- Isoleucine can promote protein synthesis and improve the level of growth hormone and insulin, to maintain balance in the body, can increase the body’s immune function, treat mental disorders, to promote an increase in appetite and the role of anti-anemia, but also with the promotion of insulin secretion. Mainly used in medicine, food industry, protect the liver, liver role in muscle protein metabolism is extremely important. If lack, there will be physical failure, such as the state of coma. Glycogenetic and ketogenic amino can be used as nutritional supplements. For the amino acid infusion or oral nutritional additives.

The best food sources for L-Isoleucine include brown rice, beans, meat, nut, soybean meal and whole meal. Since it is a kind of essential amino acid, it means that it can’t be formed in human body and only obtained from diet.
