5-HTP 50 mg 100 vcaps

5-HTP by Douglas Laboratories is a dietary supplement for serotonin support that contains 50mg of natural L-5-Hydroxytryptophan (5-HTP) extracted from seeds of the Griffonia plant in each vegetarian capsule.

Serotonin, an important brain neurotransmitter, is key in the regulation of appetite, mood, and melatonin production. The presence of serotonin in the brain is associated with a balanced emotional state. This is achieved in part by decreasing the activity of certain excitatory hormones, including dopamine and noradrenaline.

Serotonin also acts as a satiety signal in the brain, thereby naturally regulating food intake. Additionally, as a precursor of melatonin, serotonin is involved in regulating sleep patterns. Serotonin is unable to cross the blood-brain barrier and is therefore synthesized in the brain by L-5-Hydroxytryptophan (5-HTP).

5-HTP offers a number of advantages over tryptophan. Unlike tryptophan, which is produced synthetically or through bacterial fermentation, Douglas Laboratories' 5-HTP is a natural product extracted from the seeds of the Griffonia plant. 5-HTP crosses into the brain more readily than tryptophan as it is able to cross the blood-brain barrier without competition for uptake. 5-HTP is significantly more useful than tryptophan; one 50mg capsule of 5-HTP is roughly equivalent to 500mg of tryptophan.

Suggested Use

As a dietary supplement, adults take one to two capsules per day, between meals or as recommended by a healthcare professional. Vitamin B6 is necessary for the conversion of 5-HTP to serotonin; thus, to derive optimal benefits of 5-HTP, one must ensure an adequate intake of vitamin B6.
