It's too bad not more testing of vitamin D is done on a regular basis. It is a slightly more expensive report.

-In Canada for example (approx numbers from a few different studies) (farther North, less sun, less pleasant climate), 70% of people have normal vitamin D levels (lots of vitamin D supplementation in breakfast foods, which may be why, just like Iodine in salt prevented tons of goiter)

-In Canada, the remaining 20% are sub normal, and 10% are actually deficient.

Of course, this affects people with dark skins more.

Canada is THE most indoor country on the planet, worse than Scandinavians and Russia. Also the biggest Facebook user in the world, which rather go together!

The distinction in these vitamin matters is that deficiencies are VERY problematic, but there is strictly no benefit to supplementing if one is healthy/not deficient.

It's great that you were able to get tested.

I was tested the first time about 14 years ago, about a year after moving to SW Idaho. I was falling asleep every afternoon, I was constantly tired, etc. My doctor did labs and included the vit D test. I was low and told to take 1,000 units of Vit D and was given a lecture on the dangers of ODing on vit D. Reading about vit D and the relationship to illness and also covid hospitalization. I made it a point to get a lot of sunlight. I got tested and I was higher than I was years earlier, but on the very low side of the medical books normal range. Realizing that it ODing on vit D was harder than advertised, I started taking more. A couple of months later, tested again and I was at a good level and felt much better too. I think that vit D is under rated.
