"Likely you are only measuring the 25D levels, as it is easier to measure. The 25D is a precursor, and the 1,25D the active form."

Just checked, and the blood test I took "was" for the 1,25D active form, and not the precursor. Kudos to the lab for using the "right" test.

To add to the data, although I "love" milk, I have developed a sensitivity to it, so no longer drink it other than very sparingly (so no intake of D there). I also don't eat cereals (too much carbohydrate in the AM gives me a hypoglycemic condition later)--so no intake there either. Finally, I live in "the Great Northwest"--and you can imagine what opportunities there are for "solar synthesis" of D during the winter months.

So I think I'm pretty safe with the supplementation.

To continue that off topic subthread one thought further, some people find that they can drink raw milk, even though they have trouble digesting pasteurized milk. See my FR home page for more Raw Milk links, near the top.
