    Thanks for the link, but I cannot afford $65 for a disposable test which can be used only once. (Honestly, the way my finances are at this stage, I couldn't afford $65 for a test which worked forever, but having it be useful only once makes it a total non-starter.)

    I hope that some others might be able to consider purchasing this (or other) tests, though.

    (And I'd still like to know whether that alternative, "E" form of Vitamin D3 is harmful or merely not as good as the "Z" form. I'll look into it online if nobody else knows.)

    Get out into some sunlight then. At present I don't think any government has found a way to tax it in that form.
    Why use a sledge hammer to crack a nut when a steam roller is even more effective, and, is fun to drive.

    i live in new england and work indoors. i have been tested and was found low, even after supplementing at 5000 ius per day for 3 months prior to the test. 3 months more of taking 10,000 ius per day and i am still low. improved, but not yet within a safe range.

    imho, gov't recs are way too low for most people, most of whom are deficient. then again, i've pretty much stopped paying any attention to gov't rec's for health and wellness.

    the addition of supplemental d coincides with other more primal fine-tuning of my diet and i do feel much MUCH better than i did last year at this time. is it strictly from the d? probably not, but it's been a piece of the solution so i see no reason to dismiss it.
    As I ate the oysters with their strong taste of the sea and their faint metallic taste that the cold white wine washed away, leaving only the sea taste and the succulent texture, and as I drank their cold liquid from each shell and washed it down with the crisp taste of the wine, I lost the empty feeling and began to be happy and to make plans.

    I think after Octoberish I can no longer obtain vitamin d from the sun because of it's angle. Michigan would be worse than me.
    There's a nice website on vitamin D Vitamin D Council > Information on Vitamin D, Vitamin D Deficiency and Vitamin D Toxicity

    BTW there are more than 5 senses.

    In one of Cordain's books he says that it is best to get vit D from being outdoors those living in Northern areas supplement 2000 international units in winter
    Eating primal is not a diet, it is a way of life.

    I use the Carlson D3 10k pills, and love them. Buy Carlson Vitamin D3 10000 IU, softgels & More | drugstore.com

    A year ago I had my vitamin D levels checked I was very low! (I believe it was 15-18? Also, this was after having lived for 15 months in the Tropics but not spending very much time outdoors) anyway, after a year of consistently taking 10k a day (with a couple months off when I had to restock, and then days off when I forgot to take it) I'm finally up to 73! Happy day.

    I know that low Vitamin D has a huge effect on the body's ability to fight disease and other issues, and so yes, I would say that Vit D supplementation is worth is. Especially for those of us who do not spend time in the sun daily.

    I recommend watching Dr. Mercola's 7-8 part youtube series (it's 7 parts, but then he added a supplemental post) about Vitamin D. Very much worth the watch. Not all affects are immediate. And it sometimes takes us a long time to heal.

    Started supplementing a couple of years ago due to major depression during winter. Lab test showed my level in the teens. I mainly supplement from October through March. It's made all the difference for me.

    I suffer from Seasonal Affective Disorder and had my low D levels confirmed with blood tests. 6+ months of high supplementation of D3 in liquid form (10,000IU daily) brought me up to a normal level (though low for summertime). It really depends on the state of your gut, I believe. All micronutrients need to be working in concert for proper absorption. I felt a change within a couple weeks of high supplementation last Winter, even though my levels were still low.

    If you don't feel a difference, it's possible you don't need it, but you could try a lower maintenance dose to make sure you're getting enough if you don't get outside often, until you can get tested. Perhaps foolish, but I just use common sense with stuff like this, and don't really care about the tests and medical issues and plethora of articles there are out there debating the issue.

If you're one of the unlucky few who gets it, are there any bad aspects of it?

    (And I'll definitely be adding the word, "stereoisomers" to my vocabulary. I can't wait to find a conversation I can inject that into to show that I'm smart!)
    I did a little more digging and found out that the Z isomer degrades to the E isomer upon exposure to sunlight (it does this in our skin). I don't have access to the journals that talk about this, so I'm not sure what role the E isomer plays in our bodies, but my takeaway would be to make sure you keep your supplements away from direct sunlight.
