5HTP vs Tryptophan - what is the difference?

Tryptophan is another amino acid which is available in small amounts in protein-rich foods. In order to be converted into serotonin, it must be converted into 5-HTP in the brain, as tryptophan is unable to cross the blood-brain barrier

Is 5HTP safe? How long can I take it for?

Yes. +200mg of 5-htp per day has been safely taken for up to one year. We recommend taking 5-htp as/when you have an emotional need for the product.

Yes - Despite its very chemical name, 5-HTP is a naturally occurring compound.

Why should I choose brain feed's 5HTP?

How long does it take 5-HTP to work?

Small package and easy to swallow

Very small package that makes it really easy to carry around. The tablets are also small and easy to swallow. I’m not sure about mood but it helped with sleeping. When I have insomnia I take two and fall asleep in no time.

Bad headache

I bought this because I thought the seratonin would help with my anxiety and the triptofan would help me sleep. All this medicine did was give me a servere headache and couldn't sleep. It makes you feel worse than better
