A little interesting snippet of Vitamin D history that you may not have known.
The vitamin D and immune connection has at least been around for at least 100 years. It became a popular vitamin when the bone disease rickets was found out to be caused by a Vitamin D deficiency in children. By getting kids in the sun and supplementing with vitamin D they were able to prevent the improper calcification of bones and bow legs.
It also played a role in preventing the lung infection, tuberculosis. They found out that extracting Vitamin D from Cod Liver Oil could aid in the treatment and prevention of tuberculosis. Which is why you hear of cod liver oil being such a great source of Vitamin D.
Researchers are also seeing a seasonal variation in Vitamin D. Since we can create vitamin D from sunlight, during the colder months when we are indoors more often, and illnesses like the flu, upper respiratory tract infections, and incidents of septic shock increase. But once spring and summer rolls around, these conditions subside. They are thinking Vitamin D plays a big role in this since people get less sunlight when they are all covered up and indoors!
As you can see, throughout history there is a pattern with vitamin D and the immune system.
So we know there is a connection, but how does it help?
Research actually found that cells in our lungs produce high levels of the enzyme that converts Vitamin D into its active form, suggesting that the lungs use Vitamin D as part of their defence system. Our body is intelligent! It has the enzyme there for a reason, as it can help defend our lungs from invading pathogens.
Once our inactive vitamin D is converted to its active form, how does it work it’s magic? Part of the magic lies in the stimulation of cathelicidin in macrophages. Macrophages are our body’s garbage collectors, they eat and engulf pathogens, digest them, rendering them useless. They are very powerful immune cells. And they are able to do this because Vitamin D gives them a boost in their cathelicidin fighting power.
In addition to promoting the destruction and digestion of pathogens, Vitamin D is also thought to help limit the excessive production of proinflammatory cytokines that cause excessive inflammation when we get sick. This can help play a role in the prevention of dangerous inflammatory cytokine storms, making sure the body doesn't get too chaotic when battling an infection.
All these functions make vitamin D an amazing immune immune modulator. Vitamin D helps our immune system kill the infection, clean up the infection, calm down the chaos, and clear up the debris. It helps make our immune system smart!
