This Commonly Used Supplement May Be Troublesome

2015_1_8_THU_profileDo you take a supplement with calcium or know some one who does?

The research is concerning.

Calcium supplements increase kidney stone growth. Not good.

Real food sources of calcium are great.  No issues there. But, additional supplementation may be troublesome.

From: Loftus, J., Journal of the American Society of Nephrology Supplement, p. 584A, 2015).

Use of calcium supplements has been shown to increase the rate of growth of kidney stone in postmenopausal women.  A review of CT scans of such women with a history of kidney stones showed that among those taking calcium supplements (averaging 439 mg per day), stones grew at average rate of 7.8 millimeters per month, compared 4.49 millimeters among those not taking calcium. Vitamin D supplementation showed no added risk and, potentially, a protective effect (stones grew at only 3.3 millimeters per month).

This newer finding on calcium supplementation adds to the concern referenced years ago.  See previous post from 2013 on Calcium Concerns.

In response to the concerns, we re-evaluated and revised the tested and true dietary supplements reference guide. Several supplements were removed and others were added based on available research.
