Can iron and vitamin d deficiency cause head confusion and dizziness?

Not known to happen: Vitamin d deficiency is common. Many people are taking extra vit. D and drinking more nonfat milk to correct that problem. Blurred vision is also a common symptom, but is not related to vit. D (researchers are still studying vit.D). Many eye problems can cause blurry vision, so a person should be seen by an ophthalmology eye doctor. One should not try to fix his own vision by just taking vitamins.

SOD: Superoxide dismutase 10000 units three times a day until blurry vision gets better usually notice effect within a day.
