In fact, it's estimated that 25-50% of adults in the United States are deficient in Vitamin D (1).
And, it seems to be more problematic in wintertime months, when we come down with more colds and flu.
What's the Vitamin D and immune function connection?
Here's all about Vitamin D, the research regarding immunity, risk factors for deficiency, and how to get enough.
WHAT IS VITAMIN D?
Vitamin D is a fat-soluble hormone that is both synthesized naturally by the body, and absorbed in the digestive tract.
There are two forms of Vitamin D, animal-synthesized D3 (cholecalciferol) and plant-synthesized D2 (ergocalciferol).
While humans can make the active form of Vitamin D, calcitriol, from D2 or D3, the latter is considered more effective at increasing levels.
THE SCIENCE: VITAMIN D AND IMMUNE FUNCTION
Vitamin D directly supports the immune system (2). It's been shown to:
There have been mixed results on Vitamin D levels and specific disease outcomes. For example:
There have also been studies that don't show significant correlations. So, how much is enough? Subscribe for free to Breaking Christian News here
