5-HTP, 100 mg, 60 Capsules

Dietary SupplementEgg FreeGluten FreeFree of NutsDairy Free5-HTP plays a role in both sleep regulation and mood balance. 5-HTP is a precursor for serotonin, which can then be converted to melatonin (the hormone that helps us fall and stay asleep). However, 5-HTP bypasses the light-triggering system that regulates the release of melatonin, increasing both serotonin and melatonin release, regardless of light or time of day.Serotonin has a calming effect on brain chemistry, and may help to ease anxiety. Serotonin also plays an important role in many other bodily functions, including digestion, appetite, and pain perception. Our 5-HTP is naturally derived from the seeds of the African plant Griffonia simplicifolia and is combined with activated vitamin B-6 as active P-5-P, an important cofactor in serotonin metabolism.

Serene Science, 5-HTP, 100 mg, 120 Capsules

Balanced MoodDietary Supplement5-HTP (L-5-Hydroxytryptophan) is an intermediate in the natural conversion of the essential amino acid, tryptophan to serotonin, a brain chemical associated with positive mood and well-being. Preclinical studies show that 5-HTP may help support healthy levels of serotonin in the body. In addition to a balanced mood, serotonin may also support  melatonin production and a healthy sleep cycle. Serene Science® 5-HTP is derived from the seeds of the African plant Griffonia simplicifolia.

5-Hydroxytryptophan, 90 Capsules

Dietary Supplement Mood Sleep Gluten FreeEnhances sleep and helps manage stress.5-HTP increases serotonin levels to promote restful sleep, manage stress, and decrease sugar cravings. It contains pyridoxal 5'-phosphate, the active form of vitamin B6 and the necessary cofactor for the conversion of 5-HTP to serotonin.The serotonin levels in the body are associated with the regulation of sleep, mood, and appetite. A balanced serotonin level has been shown to support restful sleep, good mood, and decreased sugar cravings. There are several ways to support a healthy serotonin level. L-tryptophan and 5-Hydroxytryptophan (5-HTP) are both precursors to serotonin. However, supplementation with 5-HTP is preferable, because unlike L-tryptophan, 5-HTP cannot be shunted into other uses in the body, such as niacin or protein production. 5-HTP is well absorbed by the body and easily crosses the blood-brain barrier where it can increase the synthesis of serotonin in the central nervous system. And 5-HTP can be taken with meals without reducing its effectiveness. 5-Hydroxytryptophan (5-HTP) is the intermediate metabolite the body produces when it initiates the process of converting the essential amino acid L-tryptophan to serotonin. Therefore, supplementation with 5-HTP will bypass the conversion of L-tryptophan into 5-HTP by the enzyme tryptophan hydroxylase – which is the rate-limiting step in the synthesis of serotonin – and is a conversion that can be inhibited by a number of factors, including stress, insulin resistance, increasing age, and deficiencies of vitamin C, folate, and iron.  5-HTP is well absorbed when taken orally, with about 70 percent going into the bloodstream. Intestinal absorption of 5-HTP does not require the presence of a transport molecule, and its absorption is not affected by the presence of other amino acids; therefore, 5-HTP can be taken with meals without reducing its effectiveness. 5-HTP has been shown to have a beneficial impact on mood, sleep, carbohydrate cravings, and discomfort associated with fatigue. Numerous studies of individuals with negative mood status have shown significant positive response with 50-300 mg of 5-HTP daily. To further facilitate serotonin production, Thorne's 5-HTP formula contains pyridoxal 5'-phosphate, the active form of vitamin B6 and the necessary cofactor for the conversion of 5-HTP to serotonin. 5-HTP is commercially produced by extraction from the seeds of the African plant, Griffonia simplicifolia.
