Biological Activity: L-Tryptophan (Tryptophan) is an orally active and essential amino acid that is the precursor of serotonin, melatonin, and vitamin B3. L-Tryptophan can promote an increase in stemness and osteogenic ability of BMSCs in vitro and in vivo. L-Tryptophan inhibits cell proliferation and induced cell cycle arrest with high levels[1][2][3].
