Vitamin D has many vital functions in the body, but perhaps most essential of all, optimal levels of Vitamin D help support a robust immune system. Countless studies have shown that those with optimal levels of Vitamin D are less likely to contract a whole host of bacterial and viral infections. In certain instances, viruses can induce a massive inflammatory response capable of killing the victim. In other words, often it is not the virus that kills, but the body’s hyper-reaction to the virus in the form of uncontrolled overproduction of pro-inflammatory cytokines.

Vitamin D has an amazing ability to down-regulate the expression of pro-inflammatory cytokines. In addition to this, astonishing research has shown how people with higher levels of Vitamin D are more likely to survive cardiac arrest and coma. Being that obtaining optimal levels of Vitamin D from our modern diet is near impossible, it has never been more essential to start supplementing with a quality Vitamin D.
