Imagine your immune system as your computer anti-virus. It shields your computer against malware and virus attacks, identifying what is safe and what is malicious to your computer’s system. Like the human body, your immune system is the sentinel to the world. Because 70 to 80 percent of your immune system is found in your digestive tract, from the stomach to the colon, when it is congested with chemicals and toxins, it will affect how your immune system functions.
Among the most vital immune modulators of the body is Vitamin D. You may not know but each cell of our body contains receptor sites for Vitamin D. However, the digestive system plays an important role for absorption of Vitamin D. When the digestive tract is inflamed or irritated, Vitamin D absorption is diminished or weakened compromising communication on the cellular level. This leads to lack of absorption of fat soluble vitamins A, D, E and K, phytonutrients and essential fatty acids that depend on fats for absorption.
Converting Vitamin D into an active form that the body can absorb requires sunlight. Sufficient conversion of Vitamin D in its bio-available form will regulate Calbindin, an enzyme that facilitates absorption of dietary calcium in the intestines and converts it to a form usable for the bones. Vitamin K2 is another essential component to ensure calcium is delivered to bone instead of binding to soft tissues.
How Does Sufficient Vitamin D3 and K2 Boost Your Immunity?
When Vitamin D3 level is low, only as low as 10% of dietary calcium is absorbed by the body compared to up to 80% when available D3 is sufficient. Furthermore, Calbindin regulates Cathelicidin, a natural antibiotic produced by our immune cells. This is the reason why colds and flu increase during Fall, when there is not enough sunlight to initiate bioconversion of Vitamin D and Cathelicidin.
Another important function of Vitamin D in relation to immune function is its role in activating an immune response. Immune cells utilize Vitamin D to activate and deactivate an immune response. For instance, when there is an injury or a foreign body, the immune system triggers an immune response through inflammation to heal the wound or fight the disease. When there is an insufficient supply of D3, immune response won’t be triggered leading to an impaired neuromuscular function.
To achieve optimal immune function, it is vital to have sufficient amount of Vitamins D3 and K2 all year round. This will ensure calcium deposition to maintain bone health and strengthen immune system.
