Rhodiola rosea (2% Salidroside)**
" Studies on whether Rhodiola improves physical performance have been inconclusive, with some studies showing some benefit,[27] while others show no significant difference."
A 2007 clinical trial from Armenia showed significant effect for a Rhodiola extract in doses of 340–680 mg per day in male and female patients from 18 to 70 years old with mild to moderate depression. No side effects were demonstrated at these doses[21] Another study also found antidepressant properties,[22] possibly via the plant's inhibition of MAO-A and MAO-B.[23]
