Obviously this doesn't occur until much higher dosages are taken (unless a genetic anomaly is present, or the batch of EGCG being used is low-quality). That said, you can always take L-Tryptophan rather than 5-HTP. Also, St. John's Wort and 5-HTP have both been clinically proven to be as effective as SSRIs in alleviating/eliminating depression. This makes them the superior choice, as their side effects are much fewer and milder. http://examine.com/supplements/Green+Tea+Catechins/#summary15 http://examine.com/supplements/Green+Tea+Catechins/#summary1...
