leucine, isoleucine, valine 亮氨酸,異亮氨酸,纈氨酸

Translated from Chinese article by: Joe Hing kwok Chu

 Leucine,  when taking together with valine and isoleucine, can repair muscles, control blood sugar, and provide energy to the body tissues . It also can help increase the production of growth hormone , and helps to burn visceral fat , the fat inside the body. It is difficult to just use diet and exercise to produce the visceral fat burning result.
Leucine, isoleucine and valine are branched-chain amino acids, which help to promote muscle recovery after physical training . Leucine, the most effective branched chain amino acids, can effectively prevent muscle loss , because it can break down into glucose faster . Increased glucose can prevent muscle tissue damage, so it is particularly suitable for bodybuilders. Leucine also promotes the healing of bones , skin, and muscle tissue damage in patients. Doctors usually recommend taking leucine supplements after surgery.
Since leucine is readily converted to glucose , therefore helps to regulate blood sugar levels. People lack of leucine show similar symptoms of low blood sugar , such as headache , dizziness , fatigue , depression, mental confusion, and irritability .
The best food sources of leucine include brown rice , beans , meat , nuts, soy flour , and whole wheat . Since it is an essential amino acid and that the bodies can not produce their own, it should be obtained through diet . One engaging in high- intensity physical activity with low protein diet , should consider taking leucine supplement. Despite the availability of independent supplementary form , but is best to take leucine with isoleucine and valine together . It is more convenient to take leucine, isoleucine and valine as mixed supplement.
But , like any thing , excessive intake of leucine can also cause side effects. A high intake is known to cause pellagra and vitamin A deficiency disorders related issues , and it can cause dermatitis , diarrhea , mental disorders and other problems. Leucine diet contains too much ammonia will increase ammonia in the body and can destroy the liver and kidney function. Therefore, unless with the advice of medical provider, patients with impaired liver or kidney function should not use high doses of leucine, which may cause further deterioration of the organs .
