Amino Acids

Amino acids are the basic components of all proteins in the body. Together, they build muscles, hemoglobin, heart tissue, immune system cells, brain tissue, hormones, and more. Some amino acids also play important roles in mood balance, circulation, healing, and antioxidant defence. Natural Factors’ free-form amino acids are easy to absorb and are available as single ingredients (5-HTP, L-glutamine, etc.), but are also available in combination products for specialized support.
