BEWARE. I just went through a medical scare after using this product for a long time. Red rice yeast can have the same sort of side effects found in statin drugs. In my case, it was causing increasing muscle fatigue and joint pain, as well as exacerbating a facial tick. I went through a great deal of scans and tests looking for the cause of my worsening pains and embarrassing facial spasms. Luckily though, I am lazy. I ran out of red rice yeast and I kept procrastinating and forgetting to reorder the pills for a couple months. When I went back online to order, I googled around for a better price and I stumbled upon some negative reviews elsewhere on the web. I then made the connection that when I stopped taking red rice yeast, I started getting better!!!! I still have pains from a a couple of severe accidents, but I can get out of bed and I don't feel as inflamed. Also, my facial spasms have all but subsided, only barely trembling and only on a rare occasion, rather than violently and incessantly. There are people out there suffering the same sort of problems, often for long periods, not realizing that red rice yeast could be the culprit
