Vitamin D has been talked about as the vitamin — the one that might help fend off everything from cancer to heart disease to autoimmune disorders, if only we were to get enough of it.
“Whoa!” is the message from a committee of experts assembled by the Institute of Medicine (IOM) to update recommendations for vitamin D (and for calcium).
The IOM committee’s report, released this morning, says evidence for many of the health claims for vitamin D is “inconsistent and/or conflicting or did not demonstrate causality.” The exception is the vitamin’s well-documented (and noncontroversial) benefits on bone growth and maintenance.
The IOM panel’s report also says most North Americans (Canadians as well as Americans) have more than enough vitamin D in their blood to achieve the desired effect on bone. The committee said a blood level of 20 nanograms per milliliter (ng/mL) is sufficient for most people.
The panel set 600 International Units (IU) as the recommended daily intake for children and for adults ages 19 to 70. People ages 71 and older are supposed to get an additional 200 IU, or 800 IU a day.
That’s a fairly sizable increase over the previous recommendations of 200 IU per day through age 50, 400 IU for people ages 51 to 70, and 600 IU for people ages 71 and older. Read more »

Just five days ago we wrote about an American journalist’s observations of medicalization of one problem sometimes observed after menopause: Vaginal atrophy.
Today we see that this disease-mongering trend has popped up in Australia as well. This should be no surprise. Such campaigns are usually led by multinational pharmaceutical companies and their advertising and public relations agencies.
What caught our eye was an article on a women’s health foundation website — a foundation that posts a pretty thin excuse for why it won’t tell you its source of funding. Its article on vaginal atrophy uses classic disease-mongering language:
“Ask a woman over the age of 50 about the ‘signs of ag[e]ing’ and she’ll most likely lament about grey hairs, wrinkles and certain body parts having lost their youthful perkiness. What she probably won’t mention is that is that things are ageing “downstairs” too; up to 40% of postmenopausal women show signs of vaginal atrophy.”
The silent epidemic that no one talks about. The huge prevalence estimate — where does that 40 percent figure come from? Read more »
