A collagen synthesis-promoting amino acid composition is characterized by containing specific amino acids at a specific ratio, more specifically, by containing 10-40 parts by weight of L-arginine and/or 10-40 parts by weight of L-glutamine, as well as 5-20 parts by weight of L-valine, 8-30 parts by weight of L-isoleucine and 10-35 parts by weight of L-leucine. The composition may be useful for inhibiting skin aging, suppressing osteoporosis, promoting regeneration of tendon and ligament, and healing wounds or thermal burns. |
