Fast Fact

Only a handful of foods in nature naturally contain Vitamin D. Most other foods that contain Vitamin D (like milk) are fortified with it. In the 1930s, a Vitamin D milk fortification program was enacted in the U.S. to fight Rickets, a disorder that causes the weakening of bones in children. Also, keep in mind that Vitamin D3 has been shown to be much more effective than Vitamin D2.

Why it's important for immunity

Think of Vitamin D as an equalizer for the immune system, especially helping our immune systems stay balanced during the cold and flu season. If our immune systems have too much stimulation, autoimmune diseases can set in. With too little immune system activity, infections are more likely. In people that have low levels of vitamin D, both of these extremes have been shown to be more prevalent.

In 2009, the National Institute of Health stated that low Vitamin D levels are associated with frequent colds and influenza.
