The data is in. If you have a vitamin D deficiency, you can expect to suffer from more infections than those who don’t.
One of the most common types of infections suffered by those with a vitamin D deficiency is a respiratory infection. This is an infection that attacks any part of the respiratory system – from your nose all the way down to the bottom lobe of your lungs.
Researchers found that 93% of all patients with bronchiectasis were deficient in vitamin D! That’s a lot! What this means to you is that with a vitamin D deficiency you are a sitting duck asking for infections to fly your way and make you sick.
That’s exactly what the scientists found – 31% of the patients had evidence that the microbe called Pseudomonas aeruginosa was colonizing their lungs.
The deficiency creates defects in a type of cell called a neutrophil which is very important for your immunity. In fact, patients who were deficient in vitamin D had higher levels of inflammation markers in their sputum – AND their lung function declined rapidly in the next three years. The researchers discovered this at the follow-up consultation.
Another lung disease is tuberculosis.
Researchers at the Third Military Medical University in the People’s Republic of China knew that susceptibility to tuberculosis is greater when there’s a vitamin D deficiency. They set up a mouse study to expose vitamin D deficient and vitamin D sufficient white blood cells to tuberculosis. The cells in the culture with vitamin D produced higher levels of immune system intermediates such as IL-2, IL-10 and gamma interferon; all substances that attack microbes and boost immunity.
They concluded that vitamin D modulates the immune response during a tuberculosis infection by insuring that the cells mature and function properly.
These two studies are real evidence that vitamin D influences your immune system. All you have to do now is get your levels to the optimal zone and keep them there.
NOTE: There are a few very rare contradictions to taking vitamin D. Those with high blood calcium levels should not take vitamin D. Conditions causing high blood calcium can be caused by:
- primary hyperparathyroidism (most common cause)
- granulomatous TB
- some cancers
Please consult your physician prior to taking Vitamin D.
