I'm giving this 5 stars because it definitely works as far as what I wanted to take it for... (acne, anxiety, weight loss). My acne nearly cleared up in 2 weeks, I lost 5 pounds, and while it doesn't directly help my anxiety, I don't have the "after effects" of panic such as feeling drained, headachy, etc.
This issue that *I* have with it (and this is due to my own lack of research) is I have psoriasis and ankylosing spondylitis (both autoimmune conditions). Well - this stimulates your immune system, so it is causing both of my conditions to flare pretty badly. :-( I'm disappointed because I really love it otherwise.
