OK, so I am a Health and Nutrition Education student who is writing a thesis on the global crisis of vitamin D deficiency. This means that my inbox is always full of new information about vitamin D deficiency. I have not yet formed an opinion about this online test. But as I read through it, I remembered someone - sorry brain too old and fried to remember name - on Life with Lupus writing about sneezing attacks. So, I thought that I would post the link and ask for comments on the questions that it asks. The "test" has about 30-31 questions and can be finished fairly quickly.
It was sent to me with the following description.
A fun way to 'test' your vitamin D levels and find out how much sunshine time you need per day. Take your test at http://www.vitamindelta.org/ - be sure to leave your suggestions for improvement at the end.
Of course for many of us the problem is that we can't get anywhere near the sunshine time that we need to synthesize adequate amounts of vitamin D. But I would love to know if you found the "test" to be fun and if you also found it to be helpful.
