Griffonia Simplicifolia Seed Extract
5-HTP (5-Hydroxytryptophan) is a chemical by-product of the protein building block L-tryptophan. It is also produced commercially from the seeds of an African plant known as Griffonia simplicifolia 5-HTP is used for sleep disorders such as insomnia, depression, anxiety, migraine and tension-type headaches, fibromyalgia, obesity, premenstrual syndrome(PMS), premenstrual dysphoric disorder (PMDD), attention deficit-hyperactivity disorder (ADHD), seizure disorder, and Parkinson's disease.
How does it work?
5-HTP works in the brain and central nervous system by increasing the production of the chemical serotonin. Serotonin can affect sleep, appetite, temperature, sexual behavior, and pain sensation. Since 5-HTP increases the synthesis of serotonin, it is used for several diseases where serotonin is believed to play an important role including depression, insomnia, obesity, and many other conditions.
What is 5-HTP?
The body produces serotonin through a series of chemical steps, starting with the amino acid L-tryptophan. One of the chemicals on the way from transforming L-tryptophan to serotonin is 5-HTP.
The chemical was only available via prescription until 1995, when the United States Food and Drug Administration (FDA) approved it as an over-the-counter (OTC) supplement.
Side Effects & Safety:
5-HTP is POSSIBLY SAFE when taking by mouth appropriately. 5-HTP has been used safely in doses up to 400 mg daily for up to one year.
Other potential side effects of 5-HTP include heartburn, stomach pain, nausea, vomiting, diarrhea, drowsiness, sexual problems, and muscle problems.
5-HTP is POSSIBLY UNSAFE when taken by mouth in large doses. Doses from 6-10 grams daily have been linked to severe stomach problems and muscle spasms.
Special Precautions & Warnings:
Children: 5-HTP is POSSIBLY SAFE when taken by mouth appropriately. Doses of up to 5 mg/kg daily have been used safely for up to 3 years in infants and children up to 12 years-old. As with adults, there is also concern about the potential for eosinophilia-myalgia syndrome (EMS) in children, a serious condition involving extreme muscle tenderness (myalgia) and blood abnormalities (eosinophilia).
Pregnancy and breast-feeding: There is not enough reliable information about the safety of taking 5-HTP if you are pregnant or breast feeding. Stay on the safe side and avoid use.
Surgery: 5-HTP can affect a brain chemical called serotonin. Some drugs administered during surgery can also affect serotonin. Taking 5-HTP before surgery might cause too much serotonin in the brain and can result in serious side effects including heart problems, shivering, and anxiety. Tell patients to stop taking 5-HTP at least 2 weeks before surgery.
