I had been taking these for over a year and decided to stop after I got great reports from the doctor about my cholesterol and triglyceride levels. I won't do THAT again. A year after stopping, my cholesterol was borderline too high again and the doctor was concerned. The only thing I had changed was taking the guggul. I'm back to taking them and will never stop again.
My husband refuses to go on a prescription drug and has "hereditary" cholestrol. We changed our diets and his cholesterol remained the same. We added this and a red yeast rice supplement and he has dropped 45 points so that he's hovering at about 200 - not perfect, but much better.
I can't tolerate the Rx cholesterol stuff and am trying this. I've noticed renewed energy and a more positive state of mind - not sure if its from the guggul ;>) Too early to do another blood test to see if it is doing the job. But I bet it is!!
