I mean goodness, it's not like it's now impossible to get. You go to a doctor and get a prescription.
Research continues, so saying things like we might never know the long term effects is silly. The MCC is following strict guidelines here and although it may not be scheduled everywhere it is agreed everywhere that you should talk to a doctor first and that the long term effects are unknown.
The findings of this review suggest that exogenous melatonin is a relatively safe substance when used in the short term, over a period of days or weeks, and is safe at relatively high doses and in various formulations. However, the safety of exogenous melatonin when used in the long-term, over months and years, remains unclear.http://www.ahrq.gov/clinic/epcsums/melatsum.htmConclusions
Evidence suggests that melatonin is not effective in treating most primary sleep disorders with short-term use, although there is some evidence to suggest that melatonin is effective in treating delayed sleep phase syndrome with short-term use.
Evidence suggests that melatonin is not effective in treating most secondary sleep disorders with short-term use.
No evidence suggests that melatonin is effective in alleviating the sleep disturbance aspect of jet lag and shiftwork disorder.
Evidence suggests that melatonin is safe with short-term use.
Evidence suggests that exogenous melatonin has a short half-life and it penetrates the blood-brain-barrier.
Evidence suggests a link between endogenous melatonin and the sleep cycle.
Evidence suggests a link between endogenous melatonin and the temperature rhythm.
http://www.livestrong.com/article/11...#ixzz1vscN2KUJMelatonin has gained in popularity as a sleep aid, especially for lessening the effects of jet lag. Unfortunately, the long-term effects of this naturally-occurring amino acid are unknown for humans, and many doctors warn against its continual use. However, initial research using lower mammals has promise for long-term human consumption. It is highly recommended to discuss the use of melatonin with a health care provider, especially because melatonin is not regulated by the FDA and commercial supplements may differ in regards to quality and purity.
