Product Description
5-hydroxy tryptamine (5-HTP) is a chemical neurotransmitter obtained from the decarboxylation and hydroxylation of an amino acid (l-tryptophan). It obtained on a commercial basis from the mature seed of African Plant(Griffonia simplicifolia). 5-HTP is obtained from the seed of a plant that is native to West and Central Africa. The woody plant is about 10 feet tall, flanked by green flowers and black pods.
Indigenous people have used this plant for various traditional reasons like the promotion of normal gastro-intestinal functions in people with diarrhea and other psycho-related problems before the advancement in science. 5-HTP has a chemical formula of C11 H12 N2 O3 and a molecular mass of 220, its chemical name is 2-amino-3-(5-hydroxy-1H-indol-3-yl)propanoic acid.[2] The compound has been reported to help promote sleep and other neuro-related functions. Evidence presents that the plant extract can boosts the serotonin level in the body, thereby supporting a healthy body mood.[1].
The extract has also been found to cause some mild side effects like nausea, drowsiness, and reduced libido [4]. The majority of the excellent benefits of 5-HTP lies in the ability to be converted to serotonin. Though the extract has many potential benefits, it is yet to be certified by the FDA due to low-quality clinical studies [3}.

Product Benefits
Over time there has been a surge in the use of 5-HTP extract for various health reasons. The extract is being sold in various forms. Below are the benefits of 5-HTP
Restful Sleep
American sleep association (ASA) estimates that 50-70 million American adults have a sleep disorder. The 5-HTP extract is a precursor of serotonin and melatonin which are known to improve sleep.5-HTP at a dose of 50mg or less can improve Rapid eye movement(REM) sleep. The depth of REM is dose-dependent.[6]. The packaged extracts are being sold as dietary supplements in various supermarkets at different strengths such as 50mg,150mg,200mg. A combination of 5-HTP with GABA (Amino acid extract) have a significant role in decreasing sleep latency, thereby improving the quality of sleep. [2]
Mood Support
300 million people have been estimated to be depressed worldwide (WHO,2017),this has made people turn to Complementary and alternative Medicine for solution in the US. In a study, 5-HTP extract formulated in an extended-release manner can enhance the mood in people who have been reported to be resistant to depression treatment. The slow-released formulated 5-HTP extract could improve the condition of people that have been diagnosed with Obsessive-compulsive disorder(OCD)[7]. 5-HTP can bring about mood-boosting when used with other neurotransmitters. Regular daily intake of 50-100mg three times daily of the extract could give beneficial mood enhancement if taken in a week [2]. 5-HTP is a natural mood booster and by extension discourage processes that leads to pain.
Head Calming
Migraine occurs in 4% of the adult population worldwide (WHO, headache facts,Migraine2015). Before now, the cause(s) of migraine is yet unknown, but with the advancement in technology,it was reported that a decrease in the level of 5-HTP(serotonin precursor) could lead to migraine attacks amongst other causes[10]. 5-HTP plays a significant role in the reduction of the Migraine. A Davalos, F Titus in a research carried observed that 5-HTP extract produced an improvement in 75% of the patient (migraineur) with minimal side effect by increasing serotonin level in the brain [11]
Joint Aches & Pains
2-8% of the world population suffers from a high level of pain. Serotonin depletion has been implicated to be one of the causes of the pain. The 5-HTP extract has been reported to effectively boosts the serotonin level in the body, consequently supporting the process that leads pain reief[12].
Weight Management
5-HTP through chemical processes produces serotonin which supports the serotonin level in the brain. Serotonin gives a sense of fullness, thereby reducing your appetite. In a research study, it was observed that tryptophan, converted to 5-HTP affects gastric emptying and eating appetite [13]. Currently, there is insufficient evidence, but 5-HTP has been reported to have an anxiolytic effect.

Product Benefits
Over time there has been a surge in the use of 5-HTP extract for various health reasons. The extract is being sold in various forms. Below are the benefits of 5-HTP
Restful Sleep
American sleep association (ASA) estimates that 50-70 million American adults have a sleep disorder. The 5-HTP extract is a precursor of serotonin and melatonin which are known to improve sleep.5-HTP at a dose of 50mg or less can improve Rapid eye movement(REM) sleep. The depth of REM is dose-dependent.[6]. The packaged extracts are being sold as dietary supplements in various supermarkets at different strengths such as 50mg,150mg,200mg. A combination of 5-HTP with GABA (Amino acid extract) have a significant role in decreasing sleep latency, thereby improving the quality of sleep. [2]
Mood Support
300 million people have been estimated to be depressed worldwide (WHO,2017),this has made people turn to Complementary and alternative Medicine for solution in the US. In a study, 5-HTP extract formulated in an extended-release manner can enhance the mood in people who have been reported to be resistant to depression treatment. The slow-released formulated 5-HTP extract could improve the condition of people that have been diagnosed with Obsessive-compulsive disorder(OCD)[7]. 5-HTP can bring about mood-boosting when used with other neurotransmitters. Regular daily intake of 50-100mg three times daily of the extract could give beneficial mood enhancement if taken in a week [2]. 5-HTP is a natural mood booster and by extension discourage processes that leads to pain.
Head Calming
Migraine occurs in 4% of the adult population worldwide (WHO, headache facts,Migraine2015). Before now, the cause(s) of migraine is yet unknown, but with the advancement in technology,it was reported that a decrease in the level of 5-HTP(serotonin precursor) could lead to migraine attacks amongst other causes[10]. 5-HTP plays a significant role in the reduction of the Migraine. A Davalos, F Titus in a research carried observed that 5-HTP extract produced an improvement in 75% of the patient (migraineur) with minimal side effect by increasing serotonin level in the brain [11]
Joint Aches & Pains
2-8% of the world population suffers from a high level of pain. Serotonin depletion has been implicated to be one of the causes of the pain. The 5-HTP extract has been reported to effectively boosts the serotonin level in the body, consequently supporting the process that leads pain reief[12].
Weight Management
5-HTP through chemical processes produces serotonin which supports the serotonin level in the brain. Serotonin gives a sense of fullness, thereby reducing your appetite. In a research study, it was observed that tryptophan, converted to 5-HTP affects gastric emptying and eating appetite [13]. Currently, there is insufficient evidence, but 5-HTP has been reported to have an anxiolytic effect.
