Product Description

Andrew Lessman 5-HTP
Andrew Lessman’s 5-HTP provides a concentrated natural source of the amino acid, 5-hydroxytryptophan (5-HTP) from Griffonia Simplicifolia Seed. 5-HTP is a metabolic intermediate of the essential amino acid tryptophan and is the immediate precursor to the important neurotransmitter serotonin.

As a result, 5-HTP plays an essential role in our body’s synthesis of serotonin, which helps to enhance sleep quality while also promoting positive mood and supporting digestive system function and appetite control. Serotonin levels have been shown to be associated with the regulation of sleep, mood, appetite and the digestive process, which makes supplementing 5-HTP an important means of supporting these essential functions. Clinical research has shown that
5-HTP has the ability to cross the blood-brain barrier, providing a direct means of promoting serotonin production and its benefits.

Furthermore, 5-HTP also supports melatonin synthesis, which helps to regulate normal sleep schedule and may enhance sleep quality. 5-HTP can also promote healthy levels of other essential neurotransmitters and other neurochemicals, including dopamine and norepinephrine.

In short, 5-HTP is a simple, natural means of supporting the brain and healthy neurochemistry, along with sleep, mood and even digestive function.
