There are a lot of natural supplements that many bodybuilders and those suffering from depression who low-carb and use supplements which affect thyroid and the central-nervous-system.

Two supplements which seem to be popular are 5-HTP and Inositol ( you can find both at great prices at www.vitaminshoppe.com A lot of people have reported great sucess with these ( moreso it seems with inositol ) but with larger dosages.

Even after losing 100+ pounds and being in the best shape of my young life, I still suffer from depression and social anxiety disorder, although without realizing I was taking some of the above mentioned supplements that were in other supplements I was using and I started to feel better but didn't know why.

I'll let you know how these supps work out.
