Yes!<p>Also, do NOT mix 5-HTP with St-John&#x27;s Wort (don&#x27;t mix St-John&#x27;s Wort with anything, really.).<p>You may want to look up L-Tryptophan instead of 5-HTP. From my understanding (I am no doctor or scientist, but I do research what I put in my body), here is the order your body synthesize Serotonin: Tryptophan &gt; 5-HTP &gt; Serotonin &gt; Melatonin. You may want to start with the Tryptophan itself. However, since taking 5-HTP, I have no interest in trying this out or taking any more of those supplements because I am feeling well now.<p>It&#x27;s also recommended to take EGCG (green tea extract) along with 5-HTP to keep your gut from absorbing the supplement and producing Serotonin there instead of in the brain. (It could possibly lead to heart valve failure if you don&#x27;t!)
