I too try to encourage my family to get their Vitamin D levels checked. I'm always sending them articles on Vitamin D and M.S. Some have complied, but most have not. I recently sent them the article on pregnant women and babies with low Vitamin D. My husband's initial test levels were very low and he has been taking 4000IU daily for about three years now.
Two years ago, I also gave information to my husband's neurologist. But, I didn't get much response from him. One family member asked her doctor and he said "do you go outside". If so, you don't need extra Vitamin D. Well, he should have tested them before he made such a broad declaration.
Wonder what it will take to get our doctors on the bandwagon?
