Winter Wellness: The importance of Vitamin D

Vitamin D is one of the most important vitamins for overall health and wellness. It plays a role in the functioning of approximately 2000 genes. It is necessary for heart and respiratory health, balances minerals responsible for bone formation, regulating immune function, brain and nervous system functioning, supports healthy pregnancy and also acts as an antioxidant. Whew! This vitamin does a lot! On the flip side most people, especially in northern climates (hey Minnesotans!), are deficient in this critical vitamin. This condition is only exasperated in the winter when we are spending less time outdoors while also having to wear more layers making it extremely hard to maintain proper vitamin D levels.

This all comes at a time when we need proper vitamin D levels the most. Low levels of vitamin D can weaken our bodies natural defense systems and make us more susceptible to illnesses like the cold and flu.  Supplementing with vitamin D, especially in the winter, can help you stay healthy and avoid respiratory infections. Vitamin D can act directly on the immune system by regulating your body’s antimicrobial peptides, which kill pathogens directly.
