What they said about vitamin D then…
A few months ago I posted about calcium supplements and vitamin D supplements. I’m not a big fan of taking a lot of pills (or any, actually), so I did a little more research into what the most current evidence-based studies recommended.
Regarding calcium, I found that it’s best to get calcium from foods in my diet, such as dairy products and certain vegetables. I’ve been trying to do that.
And what about vitamin D? Calcium supplements often include vitamin D because it helps with absorption of calcium. Low vitamin D levels have also been associated with some cancers and autoimmune diseases.
The Institute of Medicine (IOM), which looked at multiple studies on the subject of vitamin D, reported
…the evidence supported a role for these nutrients in bone health but not in other health conditions. Further, there is emerging evidence that too much of these nutrients may be harmful.
The IOM recommended 600 I.U. daily for bone health.
OK, I thought, I could take a small tablet once day. I like my bones.
And what they say now
A new report published this month contradicts the IOM report of 2010.
Published in the British medical journal The Lancet, this latest meta analysis—a study that combines and analyzes data from dozens or hundreds of other studies—basically says “Millions of adults who collectively spend vast sums on vitamin D supplements to prevent osteoporosis would do well to save their money.”
The report’s authors found that supplemental vitamin D did not significantly increase bone density enough to prevent fractures, so “Most healthy adults do not need vitamin D supplements.”
Now they tell me. I still have half a bottle left.
And because vitamin D testing is expensive, as are most supplements, the authors noted:
The targeting of low-dose vitamin D supplements only to individuals who are likely to be deficient could free up substantial resources that could be better used elsewhere in health care.
Amen to that.

I’ll finish off the bottle, because I don’t like to be wasteful. But then I’m saving my money.
