6. Vitamin D and Specific Health Conditions
Vitamin D plays a significant role in preventing and managing various health conditions. Understanding these connections can help you appreciate the importance of maintaining adequate vitamin D levels.
6.1 Multiple Sclerosis (MS)
Research suggests a link between vitamin D deficiency and an increased risk of multiple sclerosis (MS). Studies have shown that people with higher vitamin D levels have a lower risk of developing MS. A prospective study of dietary intake of vitamin D found women with daily intake above 400 IU had a 40% lower risk of MS. Vitamin D’s role in regulating the immune system may help protect against this autoimmune disease.
6.2 Type 1 Diabetes
Type 1 diabetes (T1D) is another autoimmune disease that has been linked to vitamin D deficiency. Some studies suggest that children who receive vitamin D supplements during infancy have a lower risk of developing T1D. Early evidence suggesting that vitamin D may play a role in T1D comes from a 30-year study that followed more than 10,000 Finnish children from birth: Children who regularly received vitamin D supplements during infancy had a nearly 90% lower risk of developing type 1 diabetes than those who did not receive supplements. While more research is needed, ensuring adequate vitamin D intake may help reduce the risk of this condition.
6.3 Flu and the Common Cold
Vitamin D may play a role in preventing the flu and the common cold. Studies have shown that vitamin D has some benefit, don’t skip your flu shot. A randomized controlled trial in Japanese school children tested whether taking daily vitamin D supplements would prevent seasonal flu. [67] The trial followed nearly 340 children for four months during the height of the winter flu season. Half of the study participants received pills that contained 1,200 IU of vitamin D; the other half received placebo pills. Researchers found that type A influenza rates in the vitamin D group were about 40% lower than in the placebo group; there was no significant difference in type B influenza rates.
6.4 Tuberculosis (TB)
Before the advent of antibiotics, sunlight and sun lamps were part of the standard treatment for tuberculosis (TB). [69] More recent research suggests that the “sunshine vitamin” may be linked to TB risk. Several case-control studies, when analyzed together, suggest that people diagnosed with tuberculosis have lower vitamin D levels than healthy people of similar age and other characteristics. [70]
6.5 Other Autoimmune Conditions
The Vitamin D and Omega 3 trial (VITAL), a randomized double-blind placebo-controlled trial following more than 25,000 men and women ages 50 and older, found that taking vitamin D supplements (2,000 IU/day) for five years, or vitamin D supplements with marine omega-3 fatty acids (1,000 mg/day), reduced the incidence of autoimmune diseases by about 22%, compared with a placebo.
7. Factors That Can Interfere with Vitamin D Absorption
Several factors can interfere with your body’s ability to absorb vitamin D, reducing its effectiveness. Being aware of these factors can help you take steps to mitigate their impact.
