In this video, I’m going to talk to you about what vitamin D does to your immune system.
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 episodes of flu , cold and other inflammatory conditions
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.
