L-Glutamine 5g:Glutamine is one of the most abundant amino acids in the body. Research shows that glutamine provides various benefits in terms of immunity, muscle protein synthesis and recovery, as well as, gut health. Glutamine actually supplies 35% of nitrogen to muscles to synthesise proteins. This, in turn, will promote protein synthesis. Why is this important? Well, the benefits of maintaining a high nitrogen balance in the muscle prevents muscle breakdown, therefore retaining more muscle. This equates to a leaner you! A leaner you means you have less body fat, so, in essence, glutamine may help with the reduction of overall body fat.
