5-HTP (5-hydroxy L-tryptophan) is a naturally occurring metabolite of the amino acid tryptophan. 5-HTP is converted in the brain to serotonin, a neurotransmitter substance found at the junctions (synapses) between neurons. 5-HTP helps maintain mental and emotional well-being and promotes healthy sleep.* Doctor’ s Best 5-HTP is extracted from the seeds of the Griffonia simplicifolia plant.*

This enzyme can be hindered by stress and conditions such as Vitamin B6 deficiency, which is one reason B6 is included in this formula. Additionally, Pyridoxal phosphate (vitamin B6) is necessary for 5-HTP to be converted to serotonin. Vitamin C participates in the conversion of tryptophan to 5-H... [Read More]
