Why Vitamin D Supplements Are NOT the Same as Sunlight

The assumption that vitamin D supplements will protect you against diseases associated with low vitamin D levels is incorrect, according to Australian researchers. The report found that vitamin D supplements are immunosuppressive and may actually make diseases worse.

Vitamin D Nuclear Receptor (VDR) influences the expression of over 1,000 genes, including those associated with diseases such as cancer and multiple sclerosis. According to the new study, supplemental vitamin D actually blocks VDR activation, which is the opposite effect to that of sunshine.

Instead of positively impacting gene expression, vitamin D supplements appear to suppress your immune system. 

Vitamin D deficiency, the researchers pointed out, is likely not a cause of disease but rather is a result of the disease process. And increasing vitamin D intake may make the diseases worse.

The body regulates production of all the vitamin D it needs, the researchers said, and dysregulation of vitamin D by supplementation has been associated with many chronic diseases.


Dr. Mercola’s Comments:

As with most nutrients and compounds, it is always best to get them from their natural sources, and vitamin D is no exception. In fact, according to these new results, it may be one of the most potent examples of what can go wrong if you veer too far from nature.

I have always found it peculiar that the only vitamin that is not in breast milk is vitamin D. To me that is a giant clue that we were NOT designed to swallow vitamin D. Newborn infants, just like you, were designed to get this from exposing their skin to natural sunlight.

Folks, without question, the best way to get the right amount of vitamin D is to spend some time in the sun. 

You always want to avoid getting burned, but generally speaking you can safely spend anywhere from 20 minutes to two hours in the sun every day with beneficial effects. If you have dark-colored skin or live far from the equator, you will need to spend more time in the sun than someone who is light-skinned living close to the equator.

The only time you don’t need to worry about whether or not you’re getting too much, or too little, vitamin D is when your body makes it naturally from the sun. There is still massive confusion out there, even among health care professionals, about what’s healthy and what’s not when it comes to sunlight and vitamin D.
