Leucine is an α-amino acid that is used by the body to synthesize proteins. As an essential amino-acid , leucine is usually obtained from the diet. Leucine helps with the growth and repair of muscular and bone tissues, in the production of growth hormone, and is instrumental in would healing. Leucine also generally helps preserve muscle protein after severe trauma . Having enough leucine in your diet is important to ensure that protein synthesis takes place adequately.
L-Laecine’s health benefits
1) According to a study published in the journal PLOS One in 2014, leucine helps improve skeletal muscle regeneration in rates after cryolesion
When conducting this study, scientists supplemented baby rats with leucine a few days before muscle stress or trauma, cryolesion, to see whether the supplement would affect the regeneration of muscle tissue. The researchers found that leucine help increase myofibre size in treated animals, and a reduction in collagen type III epression, which is detrimental to good muscle growth. In addition to these positive benefits, leucine also minimized decrease in tetanic strength and an increase in fatigue in the muscles affected, enabling them to recover and regrow more quickly.
Thus, the study concluded that leucine supplementation led to larger myofibre size and greater strength recovery potential in muscles that have undergone cryolesion or trauma, suggesting that leucine could be used for muscle recovery after injuries for human beings.
2) Leucine can help alleviate Diamond-Blackfan anaemia
A study published in the journal Blood in 2012 found that leucine supplements, or L-leucine, can help alleviate Diamond-Blackfan anemia (DBA). DBA is a congenital syndrome of bone marrow failure, usually seen in children. It manifests usually as normochromic macrocytic anaemia. Protein therapy might be the best way to treat DBA, and leucine supplementation, according to this study, is the most effective amino acid therapy available.
3) Leucine can help prevent the symptoms of Type 2 Diabetes
Another study published in the journal PLOS One is 2013 found that leucine supplements could help individuals be spared from insulin-resistance by regulating adiposity levels. Insulin resistance is a key symptom of two diabetes, which means that your cells are unable to absorb the insulin required to adequately deal with the sugar in your body. Insulin resistance also often leads to obesity.
While this study remains unclear as to the exact mechanism through which leucine supplementation prevents insulin resistance, it does recognize its potential in helping avoid diet-induced obesity and improving overall insulin sensitivity.
While some of the more important benefits of leucine supplementation are mentioned in this article, there are even benefits being researched. As an essential amino acid leucine is literally a building block of the human body.
