Osteoporosis and vitamin D.

The International Osteoporosis Foundation (IOF) today issued a statement on older people and vitamin D, based on examination of evidence.

The best available clinical indicator of vitamin D status is blood 250HD. This should be 75 nmol/l in older people.

The average vitamin D required to reach this is 20 to 25 micrograms/day.

Intake may need to double in the obese, those with osteoporosis, where sun exposure is limited and in cases of poor absorption.

High risk individuals should have their blood levels tested.

The response to vitamin D3 supplementation is not affected by aging.

The full IOF release is here.

  1. Hello! I recently read your blog and I loved it. I was wondering if you were intending to publish additional web content to go in conjunction with this blog?

    • This autumn, when the blog has been running for about a year, we’ll publish additional content. This will add to the simple ‘news’ items done now with ‘all-abouts’, collections of research on topics of interest.
