L-Tryptophan 500 Mg has no groggy after-effect like with sleeping pills. Natural sleep.

Unacceptable L-Tryptophan

This product did not aid me, and had a subsequent effect of feeling a dull fuzzy headache the next morning.


I will be buying more L-Tryptophan.

L tryptophan

These definitely help relax you and aid me in getting back to sleep at night. Great product. Best paired with 5HTP at same time for maximum relax.
