Leucine can be used as nutritional supplement and flavoring enhancer. It can prepare amino acid infusion and comprehensive amino acid preparation, hypoglycemic agent and plant growth promoter.
Leucine's role includes working with isoleucine and valine to repair muscles, control blood sugar, and provide energy to body tissues. It also increases the production of growth hormone and helps burn visceral fat, which is difficult to have an effective effect on them only through diet and exercise.
Leucine, isoleucine and valine are branched chain amino acids, which help to promote muscle recovery after training. Leucine is the most effective branched chain amino acid, which can effectively prevent muscle loss, because it can decompose and convert into glucose faster. Increasing glucose can prevent muscle tissue damage, so it is especially suitable for bodybuilders. Leucine also promotes the healing of bone, skin and damaged muscle tissue. Doctors usually recommend patients to take leucine supplements after surgery.
Since it is easily converted to glucose, leucine helps regulate blood glucose levels. People who lack arginine will have symptoms similar to hypoglycemia, such as headache, dizziness, fatigue, depression, insanity, and irritability.
The best food sources of leucine include brown rice, beans, meat, nuts, soybean flour, and whole wheat. Because it is an essential amino acid, it means that the body cannot produce it by itself, but can only be obtained through diet. People engaged in high-intensity physical activity and low protein diet should consider taking arginine supplement. Although there are independent forms of supplementation, it is best to ingest with isoleucine and valine. Therefore, it is more convenient to choose mixed supplements.
