Are there any long-term studies on melatonin (5-6 years)? User: Anna |

Scientific studies needs to be financed in some way. Since melatonin isn't very expensive, nobody is interested in financing long-term studies over years and years on this product. But melatonin is available in the USA for about 15 years without ever having produced some bad news-flow of negative side-effects. User: KeyMelatonin.com |
