At first I thought this stuff was good. Was helping my mood. But soon got impatient and angry and felt toxic. Aslo started having crazy thoughts. Not me. I honestly don't believe this stuff is good. i think it might be contaminated. Don't buy this one! I have a membership to Consumerlab.com and this one wasn't tested; but trust me stay away from this one. Also tested positive for excessive lead and cadmium were: Solaray Organically Grown Excipient-Free St. John's Wort and Spring Valley Standardized Extract St. Johns Wort 0.3% 300 mg Free tip to my fellow health seekers: steer clear of all three!
