If you were to pick a single amino acid as part of your daily supplementation, L-glutamine would be a great choice. L-Glutamine makes up approximately 60 percent of the Amino Acids in skeletal muscle; hence the regulation of intramuscular glutamine has significant effects on skeletal muscle metabolism. L-Glutamine actually helps you store muscle glycogen, the primary fuel source for intense exercise.

The primary benefits of L-glutamine:
• Prevention of muscle breakdown
• Support in fat loss (from increase in muscle and production of human growth hormone)
• Support of the intestinal lining cells (enterocytes) through which all nutrients are absorbed
• Helps maintain immune health

L-glutamine is recommended for intense-training athletes and supports recovery.
