"New" bone supplement Genistein?
A few weeks ago I noticed a coupon in the paper for a Citrical product that claimed it had a bone density builder in it. Then I saw a commercial for it on TV. This caught my eye because they claim that the new ingredient, genistein is clinically proven to significantly increase bone density. Hmmmmm...that's one I've never heard of before and I've done a lot of research. So I looked it up on the web.
I found it's a soy-derived isoflavone and phytoestrogen that mimics the effects of estrogen in the body. And there was a study concluded in 2007 that found it improved or stopped the loss of bone density in women with osteopenia. That's all I found...one study. Then I found that in women with breast cancer it can negate the effectiveness of aromatase inhibitors, which are design to reduce the levels of estrogens that can promote tumor growth in some types of breast cancer.
So, here we are again with something that is potentially good for us that might hurt us in the long run. It's sounds like something we need to research a little more to see if it's ok for us to take.
Has anyone taken this supplement and if so, did it help? You can also get it naturally from eating soy products.
