Review: Works - Easy to use. Helps support my adhd medication. I noticed a difference.
Review: Really helps with depression and anxiety. - I have been tapering from 60mg of Cymbalta (I'm down to about 2.5mg now) for almost 3 years. It's been totally brutal and horrible despite how slow I have taken it. I've been taking 5htp since I got down to about 25mg of Cymbalta. THERE IS NO WAY I would ever make it through the taper without taking this 5htp. Not all 5htp brands are equal. This is the best one I have found, probably because it has the methylated B-6, and because Thorne is a generally a good quality brand to begin with. Cymbalta is an SNRI- the 5htp only boosts serotonin and not norepinephrine (just a side note, on the off chance that someone reading this is tapering off an SNRI), but still, I can't emphasize enough how much it has helped me. There are other supplements one can take to help with Norepinephrine...I haven't found one that works for me yet, but everyone is different. Also, other vitamins I take, such as vitamin d, methylated b12, and methylated b complex, have been game changers. My son (17) also has depression and anxiety. He takes this 5htp, a super high quality fish oil, vitamin D, methylated vitamin b complex, and a multivitamin. He is literally two different people depending on whether he is taking his supplements regularly (we're on good streak currently, he's been taking them nearly every day for over two months and is feeling great). I almost never write reviews, but something told me to tonight. Who knows, maybe it will help someone. :)
