L-Glutamine is an amino acid that provides a fuel source for many cells of the immune system. Glutamine is the most abundant amino acid in the blood plasma and skeletal muscle and plays a critical role in the health and well being of athletes during strenuous exercise. Body Science L-Glutamine is of the upmost quality and pure L-Glutamine supplements on the market. It is 100% pure, pharmaceutical grade meaning a 5gg serve of L-Glutamine means you’re getting 5g of L-Glutamine. Increased glutamine intake can help to maintain athlete strength, well being, stamina and recovery. Because glutamine makes up such a large portion of our skeletal muscle (approximately 60%), glutamine levels can significantly drop during times of increased exercise induced stress. With glutamine taking anywhere up to 6 days to fully replenish, strength, stamina and recovery can all decrease significantly. Glutamine is known to play a key role in protein synthesis and studies have shown that glutamine supplementation can increase protein synthesis and reduce muscle breakdown. Glutamines key roles in cell volumisation, protein synthesis, immune health and anti-catabolism make it a vital supplement for any athlete, exercise or fitness enthusiast who trains on a regular basis or struggles to maintain a healthy immune system during times of increased stressors.
