Q&A

Frequently asked questions

Can you take L-Tryptophan and 5-HTP together?
It is generally not necessary or recommended to combine them at the same time. It is best to choose one based on your specific goals or use them in separate cycles to avoid overloading your serotonin system.
Is 5-HTP more effective than melatonin for insomnia?
Melatonin works by signaling to the body that it is night, whereas 5-HTP increases serotonin, helping to reduce the mental chatter and anxiety that prevent you from falling asleep in the first place.
