5HTP has some side effects, but most people tolerate it well. Everything has some side effects and 5HTP is no different. The most commonly side effects are nausea, and loose stools or constipation. Sometimes people will experience headaches or nightmares. These side effects seem to be common among many serotonin-enhancing substances and are often reported by people taking pharmaceutical anti-depressants too.
Another benefit of 5-HTP is for depression and anxiety. Many people are unable to find a suitable anti-depressant medication. The good thing is that there are people who discovered an alternative cure in the form of supplements.5-Hydroxytrytophan is endorsed not only for people who want to lose weight or are experiencing insomnia, but also for people who are suffering from anxiety issues and depression.
