Q&A

.....I was posed a question by a fellow co-worker who was urged to increase her calcium intake to decrease her rish of osteoporosis.

She of course gets the typical dietary sources of Calcium but was urged to supplement to obtain healthy calcium levels.

She had heard, that if you supplement with Vit D(She supplements with D3 and her levels are normal), youshould decrease your calcium suplementation in half.

Is this true? Or does she not need CA supplementation at all if her D3 levels are normal. Will optimum D levels afford her to just get CA from her foods?

I found this to be a good question and was wondering what your take was on this?

Dr. Davis:

In light of the most recent observations, I believe that your co-worker is correct.

When vitamin D is raised to normal blood levels, the absorption of calcium is increased, as much as quadrupled. This means that calcium in even spinach and broccoli is much more effectively absorbed, as are calcium supplements.

The last 30 years of data on calcium supplementation failed to factor in full vitamin D restoration. It may therefore not be necessary to supplement high doses any longer if D is restored.

Add to this the study in New Zealand women who took 1200 mg Caltrate with a small to moderate dose of vitamin D: heart attack risk was doubled.

I have been advising patients to reduce calcium to no more than 600 mg per day when vitamin D is supplemented, unless otherwise directed by their doctor for specific reasons.
