You’re welcome.
I hope your children respond favorably if you try augmenting their vitamin D levels through a winter season. Incidentally, there’s a mail-in test in which you put a few drops of blood on a card and in a week or so you get back your vitamin D3 levels. It costs around $70 or so. I use it to ensure that I’m taking enough vit D3 to maintain a level around 50 ng/ml. For me, that takes about 5,000 IU daily, summer and winter, even though I’m outside a lot during summer.
If you read the linked material, you’ll have noticed that Dr. Cannell thinks levels as high as 80-100 ng/ml might be necessary to affect autistic behavior. In studies, lifeguards get to around 80 ng/ml during summer, so those aren’t dangerous levels.
I keep my own over 80. Never heard of the do it yourself blood test but they can be nearly free if the doc has a reason for insurance to test your blood. I don’t have insurance any more for the first time in my life thanks to obama. We use a faith based Health Share instead, Liberty.
