Below you mention MD said take Calcium, did they tell you amount, and fact that you also need high Vitamin D? We also need B6 for mouth health, this can be checked in bloodwork. My Rheumatologist does comprehensive blood work at least 2x a year. I also work with an Epidemiologist, who upped my calcium significantly because although it was on point, parathyroid was a little high and she said my blood was pulling the calcium from my bones. With just several months change my bone density went up. I take 1200mg of calcium daily and eat calcium rich foods, I also take 2000Lu of vitamin D daily.
