I bought this for my mom for her depression. After lots of research I found this is the best brand. I like the powder vs the capsules because the caps are 500 mg and the powder is a 500 mg scoop but you can use 1/2 the scoop or whatever amount you want to control the dosage. My mom only takes 1/2 a scoop at night and she is really liking it for her depression and improved sleep.
