Product details "L-Tryptophan"

Serotonin is a hormone that cares for the connection between nerve cells. It is naturally found in the brain and digestive track and it positively impacts your mood and sleep. 

To produce and maintain optimum serotonin levels your body requires tryptophan, an amino acid your body cannot produce. In the human body, tryptophan has been shown to improve sleep, enhance mood and regulate stress.

The basis for this formula is premium L-tryptophan, which has undergone significantly more rigorous manufacturing processes than regular tryptophan material to assure the highest purity and safety.
