Griffonia

Griffonia (Griffonia simplicifolia) is a woody plant native to West and Central Africa, whose seeds are particularly rich in 5-hydroxytryptophan, commonly known as 5-HTP. This naturally occurring amino acid is synthesised by the body from tryptophan and serves as a direct precursor to serotonin, a neurotransmitter involved in regulating mood, appetite, and sleep cycles. Because serotonin also plays a role in the production of melatonin, the key hormone governing the circadian rhythm, 5-HTP derived from Griffonia contributes to supporting several physiological functions closely linked to everyday well-being. Studies have explored its role in maintaining balanced mood and quality sleep onset. The case for supplementing with Griffonia extract lies in the difficulty of meeting 5-HTP needs through diet alone, as dietary tryptophan is directed towards many other metabolic pathways. A standardised Griffonia seed extract delivers a precise and reproducible dose of 5-HTP, making it a reference ingredient in formulas targeting sleep and nervous system balance.
