Based on the findings of this article, the OTC EGCG should "restore metabolism to youth levels." Using a decarboxylase or AADC[0] inhibitor like EGCG[1] found in green tea extract limits peripheral serotonin metabolism, especially if you're supplementing with serotonin precursors like tryptophan or 5-HTP to avoid heart-valve issues.[2] See Examine.com's note in the 5-HTP article[3] and the associated citation.[4] 800mg of EGCG 2 hours prior to supplementation demonstrated decarboxylase inhibition.
