title: By the way, doctor. A recent test showed I have some hip osteopenia. Now every day I take two Tums Ultra (800 mg of calcium) plus a multivitamin (200 mg of calcium). I also get a total of 800 International Units (IU) of vitamin D daily. I've been advised that Tums aren't sufficient. Do I need to switch to a more expensive calcium supplement?
