The Difference

Glutamine is the most abundant amino acid in muscle tissue and plays a key role in many bodily functions. Studies suggest that glutamine supplementation may prevent the loss of body mass through the positive role glutamine plays in protein synthesis. Glutamine is involved in maintaining a positive nitrogen balance and also aids in supporting the immune system. Supplementing with glutamine may also help reduce muscle soreness and rebuild muscle tissue. Start supplementing today with RCSS's Pure Glutamine Powder - Glutamine XS!*
