5-HTP (5-hydroxytryptophan or 5-hydroxy-l-tryptophan) is a natural supplement that converts in the brain into serotonin. Serotonin is an important brain chemical involved in mood, behaviour, appetite, and sleep. Serotonin is known as 5-HTP, or 5-hydroxytryptamine, and is found in many places in the body particularly the brain, gastrointestinal system, and blood cells. Benefits This information gleaned from Ray Sahelian, M.D.
"Some people who take 5-HTP notice improved mood, decrease in appetite, reduced anxiety, and better sleep. I have come across some individuals who get wired instead of sleepy when taking 5-HTP. Some find that 5-HTP helps curb appetite and leads to weight loss. This nutrient could be used temporarily for appetite suppression while other lifestyle and dietary changes are being incorporated regarding a life long plan for keeping weight off. Not everyone notices the appetite suppressing effect from 5-HTP.
5-HTP may be temporarily helpful in conditions that normally require prescription antidepressants, antianxiety agents, sleeping pills, and weight loss drugs. 5-HTP may also be helpful in some individuals with migraine headaches and fibromyalgia.
5-HTP reduces the severity of a panic attack which may indicate that panic attacks may be due to low serotonin levels.
A study in rodents indicates that 5-HTP may be useful in controlling the excessive food intake sometimes generated by stress, even if given without decarboxylase inhibitors or other drugs." This information is not intended to replace the advice of a qualified Healthcare Professional. |
