I started taking soy for controlling cholestertol several years ago
My doctor started me on Lipitor and I also started taking soy ~ When the nurse checked my cholesterol reading the next time I was there she said that I must be doing something else besides taking Lipitor and yes I was taking soy ~ I was also walking in the evening, etc. but that didn't seem to have done anything for lowering it so had asked to be put on something for cholesterol ~ By the way, I now take Simvastatin (instead of Lipitor) and it is MUCH cheaper and my cholesterol readings are even better! ~ When they quit carrying it at our GNC store I did panic ~As a woman, I definitely feel that the NON-GMO Soy Isoflavones helps my body in several ways!

Great price.
Started taking this product a few years ago when I could no longer get "Soy Balance" by Nature Made. I liked that the GNC product is natural. Only draw back is that I can only get it on line. But I just make sure I order it in plenty of time.
