I've been taking ashwagandha for about 4 months along with my medication and other multivitamins. With the amount of pills I take, it's hard to isolate effects of ashwagandha from the effects and interactions from the other pills I'm taking. But overall, I can attest its beneficial effects from my own experience and those of others'. I take abilify which helps regulate my moods but add the ashwagandha I'm much more focused and less moody.
