A collagen synthesis-promoting amino acid composition isncharacterized by containing specific amino acids at a specificnratio, more specifically, by containing 10-40 parts by weightnof L-arginine and/or 10-40 parts by weight of L-glutamine, asnwell as 5-20 parts by weight of L-valine, 8-30 parts by weightnof L-isoleucine and 10-35 parts by weight of L-leucine. Thencomposition may be useful for inhibiting skin aging,nsuppressing osteoporosis, promoting regeneration of tendon andnligament, and healing wounds or thermal burns. |
