Seeking Health 5-HTP is a dietary supplement containing 50 mg of 5-hydroxytryptophan (5-HTP) derived from seeds of the Griffonia simplicifolia plant in one capsule. This supplement improvesmood and quality of sleep. It supports weight loss by controlling appetite and supporting body regeneration.

This product is vegan and vegetarian friendly. Neither the active nor auxiliary ingredients included in the capsules contain animal-derived elements. In addition, 5-hydroxytryptophan due to its natural origin is distinguished by an excellent bioavailability and is ahead of its synthetic competitors.

Griffonia simplicifolia is a shrub plant found in Western and Central Africa. It has been known for centuries among the African population not only as a plant that heals ailments of the digestive system but also as an aphrodisiac.

Extracts from its seeds are well known for the high content of 5-hydroxytryptophan

5-Hydroxytryptophan (5-HTP) is a naturally occurring amino acid formed from tryptophan by hydroxylation involving tryptophan hydroxylase. Then it is converted to serotonin, which after playing its role is used for the synthesis of melatonin. 5-HTP is an intermediate link in reactions that lead to acquisition of biologically relevant active substances.

5-HTP as a more specialized modification of L-tryptophan
5-hydroxytryptophan is used as a precursor for serotonin and fulfils this role much better than its unmodified derivative. L-tryptophan is also used by the body to synthesize proteins or niacin (vitamin B3). 5-HTP serves only as a precursor in the synthesis of serotonin and melatonin, so it is more efficient and its action more precisely targeted.

5-HTP supplementation is much more effective than L-tryptophan supplementation. This is because 5-hydroxytryptophan bypasses the mechanisms that regulate the concentration of tryptophan in the cell and does not compete with other amino acids, so it has higher concentration and crosses the blood-brain barrier easier than the tryptophan.

Additionally, the hydroxylation reaction of L-tryptophan that leads to 5-hydroxytryptophan is one of the slower reactions on the way to the synthesis of serotonin and melatonin. The intake of 5-HTP means its avoidance and the supplement effect is felt quicker.

Better quality of sleep and improved well-being
The serotonin (5-hydroxytryptamine) formed from 5-hydroxytryptophan influences the behavior and well-being to a large extent. It has been proved that low levels of serotonin resulting from tryptophan deficiency in the diet, cause aggressive behavior and fatigue. Because of serotonin synthesized from it,  5-HTP issometimes used in the depression treatment as it increases motivation, zest for life and energy (however, it is recommended to consult a doctor before using 5-HTP for therapeutic purposes).

The reports show a beneficial effect of 5-hydroxytryptophan supplementation on the quality of sleep. This is due to melatonin, the last substance through the transformation of this amino acid. Melatonin is a hormone produced by the pineal gland. It participates in the coordination of circadian rhythms (sleep and wakefulness). Melatonin makes easier to fall asleep and causes a more stable sleep. It is beneficial for people who often wake up at night or have problems falling asleep.

Melatonin provides a healthy, calm sleep which indirectly influences well-being and body regeneration by reducing irritability, providing rest and giving energy to act.

Helps to achieve the dream figure
The study conducted among obese womenhas shown that supplementation with 5-hydroxytryptophan lowers the feeling of hunger and significantly reduces the urge to snack. Compared to the control group, the research group had a three-fold greater decrease in body weight during the experiment. It was caused by the reduced appetite and the amount of food consumed without well-being deterioration.

The above results indicate that the increased supply of 5-HTP  promotes weight loss and helps to achieve slimmer figure also among people building muscle mass. The reduced amount of food in diet does not cause hunger or irritability, just the opposite: the use of 5-hydroxytryptophan improves  mood and suppresses appetite.

Seeking Health 5-HTP delivers an effective dose of 5-hydroxytryptophan, which helps to achieve a calm sleep and through enhanced synthesis of serotonin and melatonin,positively affects the mood. It supports regeneration and controls appetite giving an invaluable support for people who want to get rid of excess fat or build an attractive figure.

Used in medicine as an adjuvant, to a small extent supporting the treatment of depression and insomnia. Due to the presence of melatonin at the same time it is improving the quality of sleep and improving the regeneration process.
5-HTP is a component of supplements supporting the production of growth hormone and it is a part of some fat reducers (reducing appetite).
