In this video, I’m going to talk to you about what vitamin D does to your immune system. I may have covered this in the past, but I think this is an important topic you should know more about.

Vitamin D is intimately connected to every single immune reaction. In fact, white blood cells have the ability to activate vitamin D.

One effect that some viruses have on the immune system is to turn off vitamin D receptors. They know that vitamin D is important, so they prevent it from becoming useful so they can thrive.

Vitamin D deficiencies occur when there’s not enough sun—like wintertime. This is one reason why we get a spike in the flu and other viruses in the winter. The Spanish flu pandemic of 1819 peaked in January.

Between November and March, we have far more instances of autoimmune diseases, like lupus, MS, type 1 diabetes, rheumatoid arthritis, and inflammatory bowel disease.

Vitamin D has natural anti-inflammatory properties. Inflammation is a huge contributor to things like autoimmune diseases.

Vitamin D is also an immune modulator. It helps regulate your immune system, so it’s not working too much (like attacking healthy body tissue) and not too little (like not being able to fight off viruses).

Vitamin D also helps create antimicrobial compounds, such as cathelicidins and defensin.

It is virtually impossible to get enough vitamin D from food alone. You need to get vitamin D from the sun.

When using high doses of vitamin D, always check with your doctor. High doses of vitamin D can increase blood/urine calcium levels resulting in calcium deposits in the kidney. Also drink 2.5 liters of fluids per day, take cofactors with vitamin D (magnesium, K2 and zinc) and have your doctor monitor your PTH, vitamin D blood levels and creatinine and avoid excess calcium supplements of high calcium foods when taking vitamin D levels over 10,000 IUs.
