With all these new data relating both CCSVI and vitamin D to MS, an obvious
question becomes “How do CCSVI and vitamin D relate to each other in
MS?” Unfortunately, I do not have a solid answer for this.

The data say vitamin D is very important for controlling autoimmune
reactions and that is one obvious reason why it is so effective in MS. On the
other hand, we know that vitamin D also affects venous health so the
possibility exists that adequate vitamin D in utero and childhood may prevent,
or greatly lessen the effect of, CCSVI. The relationship between vitamin D
and CCSVI in MS is begging for some innovative research.

Scientists at the University of Copenhagen have discovered that Vitamin D is crucial to activating our immune defenses and that without sufficient intake of Vitamin D, T-cells, the killer cells of the immune system will not be able to react to and fight off serious, life-threatening infections in the body.

- "We have discovered that the first stage in the activation of a T cell involves Vitamin D," explains Professor Carsten Geisler from the Department of International Health, Immunology and Microbiology." When a T-cell is exposed to a foreign pathogen, it has an immediate biochemical reaction and extends a signaling device or 'antenna' known as a Vitamin D receptor with which it searches for Vitamin D. This means that the T-cell must have Vitamin D or activation of the cell will cease. If the T cells cannot find enough Vitamin D in the blood, they won't even begin to mobilize."

hidden on page eight is one sentence and a small table, which shows that the benefits of vitamin D are almost entirely negated in those with the highest vitamin A intake. And the retinol intake did not have to be that high in these older adults to begin to negate vitamin D's effects, about 3,000 IU/day. Remember, young autistic children often take 3,500 IU of retinol a day in their powdered multivitamins, which doesn't count any additional vitamin A given in high single doses.

This is the largest study to date showing vitamin A blocks vitamin D's effect and explains some of the anomalies in other papers on vitamin D and cancer. For example, Dr. Rachael Stolzenberg-Solomon of the NIH conducted two similar studies on pancreatic cancer, with startling different results. Her first paper showed high vitamin D levels tripled the subsequent risk of pancreatic cancer, her second paper showed no effect. The difference, the first was conducted in a cod liver oil country, Finland, the second in the USA.
