Not for me

This made me feel horrible. I took a smaller dose than recommended and it made me sick to my stomach to the point of vomiting. I threw it away after one use.

Pleased with this product

I've only tried this product once, for treating my depression and my daughter's bipolar, but I did notice a positive difference in our moods. Needs more research, but I was pleased with the effect on my daughter and myself.

A supplement that delivers

Posted   by Sharyl
I've taken many supplements over the years and without getting blood work done, I'm never sure if some of them are working. This stuff works! I didn't realize how well it worked until I went a few days without it. It's very calming. It doesn't make me sleepy at all, it just calms me.
