I was worried I would have side effects but I have had only one good one! That is, my cholesterol has come down from very high to high normal and my doctor is delighted. So I am very happy with this supplement and have reordered it. Bear in mind that this is gentler than a statin and I gave it 6 months and followed all the other dietary advice that the doctor gave me. I have to confess that I still eat chocolate and have the odd steak too.
