Vitamin D reported to lower the risk of multiple sclerosis

A new study by Swedish researchers has reported that individuals with high levels of Vitamin D in their blood have a lower risk of developing multiple sclerosis (MS). Researchers affiliated with Umeå University, Umeå, Sweden published their findings on November 20 in the journal Neurology.

The goal of the study was to examine the association between Vitamin D (25-hydroxyvitamin D (25[OH]D)) levels and the risk of MS in blood samples collected prospectively and during pregnancy. (Prospective collection means that the samples were collected before the individuals developed MS.) The investigators evaluated 291,500 blood samples from 164,000 individuals collected since 1975 in the northern half of Sweden. They identified prospectively collected blood samples from 192 MS cases matched two to one with controls matched and samples from pregnant mothers whose offspring had later developed MS (37 women, matched five to one with controls. Vitamin D levels were measured using an ELISA, and the risk of MS was analyzed using matched logistic regression.

The researchers found that Vitamin D levels in prospectively collected blood samples were associated with a decreased risk of MS (odds ratio: 0.39). No decrease in MS risk was found in the offspring exposed to higher Vitamin D levels in utero. The prevalence of Vitamin D levels in the control women decreased gradually from 1976 through 2005.

The researchers concluded that their study supports the presence of an association between high Vitamin D levels during the years preceding disease onset and a decreased risk of MS. In the very limited material with samples drawn in early pregnancy, where month-of-birth effects were controlled for, they found no association between gestational Vitamin D levels and MS risk in the offspring. They noted that decreasing Vitamin D levels in the population may contribute to explain the increasing MS incidence that is suggested from epidemiologic studies.

MS affects woman more than men. The disorder most commonly begins between ages 20 and 40, but can be seen at any age. It is caused by damage to the myelin sheath, the protective covering that surrounds nerve cells. When this nerve covering is damaged, nerve impulses are slowed down or stopped. MS is a progressive disease, meaning the nerve damage (neurodegeneration) gets worse over time. How quickly MS gets worse varies from person to person.

As MS is an autoimmune disease, and Vitamin D is an immune booster, the findings by Swedish researchers are not at all surprising! MS affects the central nervous system (CNS), which is made up of the brain, spinal cord, and optic nerves. In MS, the immune system, which usually works to protect the body, attacks the body’s own tissue. The primary target of this attack is thought to be myelin, the protective coating around the nerve cells in the CNS that facilitates nerve conduction. The nerve cells themselves can also be damaged. Many sufferers of MS have a history of Candida Albicans, a fungal overgrowth, usually of the intestinal tract, in particular overgrowth of the ICV , but spores of Candida travel right through the body and have even been found in the brain. Candida weakens the immunity and many researchers also believe Candida to be the forerunner of cancer. They certainly like the same dank, acidic, anaerobic environment, where cells need to mutate and live off toxins in order to survive. We recommend Zinc supplementation, as well as Vitamin D (from sunlight) for our clients. It is also important to find, and eliminate, the causal factor of both MS and Candida. Allergic responses are the most common cause for Candida.
