Douglas Laboratories 5-HTP Plus

5-HTP Plus by Douglas Labs is a natural brain supplement for serotonin boosting support that may offer natural depression and anxiety relief support, natural mood enhancing support, and natural appetite suppressing support.

• May support healthy regulation appetite, mood and sleep*
• Provides support for increased levels of brain serotonin*

Serotonin, an important brain neurotransmitter, is key in the regulation of appetite, mood, and melatonin production. 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*.

Tryptophan, an essential amino acid, is a precursor for the synthesis of serotonin. Tryptophan crosses the blood-brain barrier and is converted to L-5-hydroxytryptophan, which in turn is converted into serotonin.*

As a metabolic intermediate in the conversion of tryptophan into serotonin, 5-HTP may also serve as a precursor of serotonin*. 5-HTP may offer a number of advantages over tryptophan. 5-HTP is derived naturally from the seeds of the Griffonia plant, unlike tryptophan which is produced synthetically or through bacterial fermentation. 5-HTP crosses into the brain more readily than tryptophan as it is able to cross the blood-brain barrier without competition for uptake. One 50mg capsule of 5-HTP is roughly equivalent to 500mg of tryptophan.*

5-HTP Plus Formula capsules contain 75mg of natural L-5-hydroxytryptophan (5-HTP) extracted from seeds of the Griffonia plant, together with 7.5mg of pyridoxal-5-phosphate and 50mg of a proprietary blend of the amino acids L-tyrosine and L-glutamine. This product has been certified to be free of a contaminant, peak "x", implicated in a past incidence of dietary tryptophan-associated eosinophilia myalgia syndrome (EMS).
