Re: (Yet) More on Vitamin D

[Guest guest]

Still, I find these reports a bit vague about what level of

supplementation might be effective for preventative health care, and

yet safe.

Hi :

Yep.

It seems to me that there is: A) a steadily growing degree of

agreement among apparently 'authoritative' sources that many people

are consuming a less-than-optimal quantity of vitamin D, and that

that may be more dangerous than previously realized.

(When I did a detailed analysis of my diet, which I had believed to

be pretty healthy, it said that few things I ate contained any

vitamin D, and the only reason I was consuming marginally more than

the (perhaps too low?) RDA was because I was eating at least some

fish pretty much every day).

and: Much confusion about how much is likely to be associated

with best health.

I suppose we will have to wait for more specific studies aimed at

defining the dose. Given the publicity about vitamin D lately I

would not be surprised if a number of such studies are probably

getting underway soon. For example the Nurses' Health Study database

might contain a pretty good answer to this question. At least for

women.

See: " To maintain a vitamin D3 of approximately 100 nmol/L, an adult

who is not exposed to sunlight would need to ingest 4000IU/day. The

safe upper limit for total vitamin D nutrition is at least 10,000

IU/day. Moreover, all documented cases of vitamin D toxicity with

hypercalcemia involved intakes greater than 40,000 IU/day. Thus, the

4000IU/day would be safe, since it is well below the 10,000 IU/day

generated by adults living or working in sunny environments.
