Bests & Worsts Reviews from Amazon

Bought this for my husband. He was hoping this would improve his mental health. Reason I gave this a 2 star: my husband does not drink caffinated drinks (coffee or tea). After a week of taking this at night as directed, he has not had a decent night sleep. Our conclusion is due to the caffeine. Natural or not... I am not able to drink Emergen-C which also has natural caffeine. I already drink coffee and decaffeinated tea. When I tried Emergen-C I experienced heart palpitation. We need to be careful. I hope this helps.
