Bests & Worsts Reviews from Amazon

As a stand-alone supp (compared to using it in a blend with 4+ ingredients), I don't have very much experience with 5HTP, so I admittedly don't have much to compare this product to...BUT...since taking it, my husband and I have felt an improvement in mood, especially at night when winding down and in the morning (particularly for ME - not a "natural" morning person...but has really felt easier and better lately). And when there are extra stressors or emotional challenges, I feel myself "bounce back" quicker and more easily. If you haven't yet, read "Hacking of the American Mind." In it, Endocrinologist Robert H. Lustig spends a fair bit of energy breaking down the biological "competition" between Dopamine and Serotonin, ultimately urging the reader to basically 'take back their brain' by increasing serotonin. One of the ways to do this is to supplement 5-HTP. So far, we've been really happy with our purchase.
