5-HTP Griffonia simplicifolia Extract



1. What is 5-HTP?

5-Hydroxytryptophan (5-HTP) is an amino acid that is the intermediate step between tryptophan and the important brain chemical serotonin. There is a massive amount of evidence that suggests that low serotonin levels are a common consequence of modern living. The lifestyle and dietary practices of many people living in this stress-filled era results in lowered levels of serotonin within the brain. As a result, many people are overweight, crave sugar and other carbohydrates, experience bouts of depression, get frequent headaches, and have vague muscle aches and pain. All of these maladies are correctable by raising brain serotonin levels. The primary therapeutic applications for 5-HTP are low serotonin states as listed in Table 1.

Depression Obesity Carbohydrate craving Bulimia Insomnia Narcolepsy Sleep apnea Migraine headaches Tension headaches Chronic daily headaches Premenstrual syndrome Fibromyalgia

Although 5-HTP may be relatively new to the United States health food industry, it has been available through pharmacies for several years and has been intensely researched for the past three decades. It has been available in several European countries as a medicine since the 1970s.

2. What advantages does 5-HTP have over L-tryptophan?

There are many advantages of 5-HTP over L-tryptophan. First of all, because it is one step closer to serotonin, 5-HTP is more effective than L-tryptophan. 5-HTP is also inherently safer. Although L-tryptophan is safe if properly prepared and free of the contaminants linked to severe allergic reaction known as eosinophilia myalgia syndrome (EMS), L-tryptophan is still produced with the help of bacterial fermentation (a situation that lends itself to contamination). In contrast, 5-HTP is isolated from a natural source - a seed from an African plant (Griffonia simplicifolia).

Evidence that this natural source of 5-HTP does not cause EMS is provided by researchers who have been using 5-HTP for over 25 years. They state that "EMS has never appeared in the patients of ours who received only uncontaminated L-tryptophan or 5-hydroxtryptophan (5-HTP)"(1). Furthermore, researchers at the NIH studying the effects 5-HTP for various metabolic conditions have also not observed a single case of EMS nor has a case of elevated eosinophils been attributed to 5-HTP in these studies.
