Bests & Worsts Reviews from Amazon

I have a bottle from just prior to their formula change & I have had no problem. I am afraid of re-ordering because they have now added CALCIUM CARBONATE which is COUNTERPRODUCTIVE towards proper digestion not to mention how awful it is for cardiovascular health. It can also "cause calcium buildup in your kidneys. This can lead to kidney stones, kidney blockage, or kidney failure." Furthermore, CALCIUM CARBONATE is "chalk or limestone, & is not a biologically appropriate form of calcium for human metabolism." Please don't just take my word for it. DO YOUR OWN RESEARCH. Therefore, I will no longer endorse this product. I am leaving a generous 2 stars because of this formula change, and those 2 stars go toward the old formula which has served me well for almost 2 years now.
