Because it is thought to work like serotonin antidepressants, 5-HTP has also been used for other conditions for which these antidepressants are prescribed, such as anxiety, insomnia, fibromyalgia, and migraine.  What is the Evidence for 5-HTP? DepressionSeveral small clinical trials have found that 5-HTP is as effective as antidepressants. * For example, in a six week clinical trial, 63 people were given either 5-HTP (100 mg three times a day) or an antidepressant (fluvoxamine, 50 mg three times a day). The 5-HTP was found to be as effective as the antidepressant, with fewer side effects.Anxiety However* for Insomnia : Serotonin is converted into melatonin, a 2002 systematic review of studies published between 1966 hormone need to 2000 found that only one out of 108 studies met the quality standards. The small study that did meet the quality criteria found that 5regulate sleep-HTP worked better than placebo at alleviating depressionwake cycles. MigraineSome research indicates that Because 5-HTP may prevent migraines and reduce the frequency and severity of migraines, however large randomized controlled trials are needed. In one study, 124 people were given 5-HTP (600 mg/day) or the drug methysergide. After 6 months, 5-HTP was found is thought to be as effective as methysergide in reducing the severity and duration of migraines. Another study looked at 5-HTP or the drug propranolol for 4 months. Both treatments resulted in a statistically significant reduction in the frequency of migraines. Howeverincrease serotonin levels, the propranolol group fared better, with a reduction in the duration of episodes it may increase melatonin and the number of analgesics used for the treatment of episodeshelp normalize sleep patterns. *For Fibromyalgia: Fibromyalgia is a chronic condition characterized by fatigue, widespread pain in the muscles, ligaments and tendons, and multiple tender points. A double-blind, placebo controlled study looked at 5-HTP or placebo in 50 people with fibromyalgia. After four weeks, there was improvement in pain, stiffness, anxiety, fatigue, and sleep. Side effects were mild and transient. * For Migraine : Some research indicates that 5-HTP may prevent migraines and reduce the frequency and severity of migraines, however large randomized controlled trials are needed.InsomniaSerotonin is converted into melatonin* For Weight Loss : According to the National Institutes of Health (NIH), a hormone need there is not yet enough scientific evidence to regulate sleeprate the effectiveness of taking 5-wake cyclesHTP supplements for weight loss or obesity.
