I just saw an ad for Citrical with Genistein. They were talking about the addition of genistein increasing bone mass by up to 5 percent per year. I listened to the sales pitch and there was something very familiar about the name - genistein so I went and looked through my research and found an article adapted by Medical News Today.
As fascinating as the research is I’ll give you the Reader’s Digest Condensed version. About two thirds of all breast cancers in the U.S. are effected by estrogen. That means that a lot of these women are taking either Femara or one of it’s cousins. These medications are designed to make the enzyme, aromatase keep other hormones in the body from turning into estrogen.
Now Femara and the other medications in this class are known to be tough on your bones. For example, Femara is known to reduce bone mass by up to eight percent per year. So most women that are taking an aromatase inhibitor take calcium and anything else they can to keep their bones in shape.
The problem lies with the genistein which is a plant estrogen. When it was tested on rats who had already grown tumors and were on AI’s the effectiveness of the aromatase inhibitor was decreased significantly and tumors began to grow again.
I am certainly not qualified to tell you what to put into your body but if you are taking an aromatase inhibitor I would NOT take this particular blend of Citracal. I also hope that there is some way of marking the packaging of this to warn women not to take it without consulting their physician is they are a breast cancer survivor. Finally I urge you to share this information with other women that are breast cancer survivors.
