When I was pregnant with Missy Blue I popped Tums like there was no tomorrow. I figured they were helping and the berry flavor was so good. But I developed kidney stones, which was horrible, and found that taking too many Tums can cause calcium deposits leading to kidney stones of which my current doctor agreed. With my last pregnancy I avoided taking them at all costs and this time as well I took one only if really necessary but usually endured the annoying burning feeling of my food coming up.
I was talking with a friend who told me that Tums has calcium carbonate which is not easily absorbed. I did more research and found out that it can cause more problems than kidney stones such as arthritis from calcified muscles and possibly even a heart attack as your heart is a muscle. My friend also told me about a calcium supplement she takes with bioavailable chelated (I am not getting into all that as it is way over my head or desire to really grasp) calcium and magnesium that her midwife recommends and so I began taking that. I was amazed at what a difference it made. My heartburn has almost completely stopped along with the charlie horses I would get in my legs each morning upon waking. And the round ligament pain that I always experience ended also. I sure wish I would have known this at the beginning of pregnancy! I was told that I don't "complain to the right people". :)
