Leucine is in our diet

Leucine is an essential amino acid, one of three BCAA's (the other two are isoleucine and valine). It is a source of energy for the muscles. It plays an important role in the functioning of our immune system and the protection and repair of our muscles. It prevents muscle loss in case of immobilization or diet and is a great help during major muscular efforts. It is also involved in the repair of dermal and bone tissues and the production of growth hormones. Leucine acts on blood sugar, it lowers the blood sugar level by stimulating the secretion of insulin. Our body does not know how to synthesize it. We must draw it from our diet. We find leucine in wheat germ, tuna, peanuts, salmon, fillet of beef, chickpeas , cottage cheese, and whole rice.

Leucine, a benefit for the maintenance of our muscle mass

It is important to know which amino acids to promote. Leucine loses effectiveness with aging, it no longer fulfills its role of weight control and maintenance of muscle mass. That's why older people see their muscles diminish. According to US researchers, leucine stimulates the metabolism that burns excess fat tissue and replace it with muscle tissue. It also has a role of appetite regulator.
