Immune support is a must if you want to help fend off illness.

As we discussed on Monday, vitamin D-3 is easily one of the best supplements you can take for immune support. In fact, your body cannot mount a successful immune response without vitamin D-3. That’s one of the reasons illness levels spike during the winter months.

To help properly support vitamin D-3 levels we’re discounting our high-potency 7,500 IU vitamin D-3 supplement.

Cells In Your Immune System Have Vitamin Receptors Which Indicate It’s Needed For Immune Response

The role that that vitamin D-3 has on immune response isn’t as well understood as vitamin C.

However, we know that many of the cells that make up your immune system have receptors that vitamin D-3 can bind to and this has led researchers to believe that vitamin D-3 can have a positive influence on supporting immune health.

In the journal Nutrients study authors wrote the following about how vitamin D-3 may influence immune function.

“Vitamin D metabolizing enzymes and vitamin D receptors are present in many cell types including various immune cells such as antigen-presenting-cells, T cells, B cells and monocytes. In vitro data show that, in addition to modulating innate immune cells, vitamin D also promotes a more tolerogenic immunological status. In vivo data from animals and from human vitamin D supplementation studies have shown beneficial effects of vitamin D on immune function, in particular in the context of autoimmunity.”

In addition to that, and as Dr. Wiggy has written about in articles on our blog, vitamin D-3 influences your immune system positively by helping to support aspects of health (like cardiovascular function and insulin sensitivity) for the better.

And of course, Dr. Wiggy will be using high-dose vitamin D-3 at the clinic to help some people tackle their most confounding health issues.

And perhaps the most important reason the average American should consider taking vitamin D-3 is that most people are deficient in it.

Recent trends in our behavior have pushed more people inside, and have also promoted other health conditions, that lead to vitamin D-3 deficiency.

Those who are most at-risk for developing a vitamin D deficiency are people who spend significant time indoors (which may be a lot more people currently). Consider the elderly, or infirm as well as people who have darker skin (darker skin absorbs less sunlight than lighter skin) as being at risk of a deficiency.

There are other groups of people who could be deficient, too:

• Those with diseases that affect the absorption of vitamin D in the gut (e.g., Celiac disease and Crohn’s disease)
• Those with diseases that affect the metabolism of vitamin D into its active form (e.g., chronic kidney or liver disease)
• Those who are obese (extra fat tissue hides away vitamin D instead of releasing it into the bloodstream)
• Those who take medications that enhance the breakdown of vitamin D (e.g., antiseizure medications and medicines used to treat HIV)

Not everyone needs to take a vitamin D-3 supplement, but if you’re not getting enough sunlight… and/or you’re looking to give your immune system an added boost, you should consider taking it.
