5-htp is a natural, isolated nutrient extracted from the Griffonia seed. 5HTP is the building block to your feel-good chemical messenger; serotonin (5-HT) making it a natural serotonin booster. Serotonin plays a vital role in your biochemistry because it helps to regulate mood. At night serotonin is converted into your sleep hormone melatonin to aid sleep.

The 5htp in our 5-htp 100mg tablets is extracted and isolated from Ghanian Griffonia Simplicifolia seeds. 99% of the tablet is comprised of 5-htp making it the smallest, nutrient-dense tablet available and no unnecessary bulking agents.

Anybody looking to increase serotonin levels naturally

how it works;

5-HTP is a precursor to the happy hormone called serotonin (5HT). 5HTP goes through a decarboxylase process to be converted to serotonin (5HT). 5HTP can freely cross the blood-brain barrier. It is then freely converted to serotonin making it an ideal natural serotonin support.
