L-Tryptophan supports the body's natural serotonin production.
It's the one ingredient in NeuroGolden that carries a specific interaction warning: if you take antidepressants (SSRIs, MAOIs) or other medications affecting serotonin, talk to your doctor before use, due to a potential interaction risk.
NeuroGolden's materials name L-Tryptophan but don't publish its individual milligram amount per dose.
