I have been taking plant sterols to reduce cholesterol for a couple of years now. While everyone has to decide on the effectiveness of supplements for themselves, I think that this product has really helped me. When I was told I had elevated cholesterol levels, I adjusted my diet, lost some weight and started taking these supplements. A recent blood workup reports excellent low cholesterol levels. I take 4 of these pills per day and I do feel that they have reduced my higher cholesterol and maintained a healthy lower level.
