We've often heard that Vitamin D is the sunshine vitamin. That's because upon exposure to the sun, our bodies manufacture Vitamin D. But, we can also get it from food and supplements.
The Importance of Vitamin D
But why is Vitamin D so important? There are several reasons for us to maintain a healthy level of this vitamin, that isn't actually a vitamin, but a hormone.
Where do vitamins come from?
Vitamins cannot be made by our bodies so we must get them from an outside source. In the case of Vitamin D, when the sunlight hits our skin, our bodies can synthesize Vitamin D for our use. If we spend approximately 5-10 minutes several times a week with skin exposed to the sun without sunscreen, we probably can make enough Vitamin D to keep us healthy as long as we aren't terribly deficient to begin with. Vitamin D is not stored in the body and breaks down quickly so we have to constantly replenish our supply. Much of the global population is living in a state of Vitamin D deficiency.
As a society, we don't spend as much time outside as we once did. And when we are outside, we slather ourselves with sunscreen, blocking any opportunity for our skin to absorb the sunlight. Eating the nutrient deficient food of the Standard American Diet (SAD) also contributes to our deficiency. It's important to find out if you are deficient in Vitamin D.
When I was diagnosed with breast cancer, I found out that I was quite deficient in this essential hormone. That, along with other poor lifestyle choices, may have contributed to the cancer. It was a wake-up call for sure. I am no longer Vitamin D deficient. This can be found through a simple blood test.
How much Vitamin D is enough?
Infants (0-12 months) - 400 IUs or 10 mcg
Children (1-18) - 600 IUs or 15 mcg
Adults (to age 70) 70-600 IUs or 15 mcg
Adults (over 70) 70-800 IUs or 20 mcg
Pregnant/lactating women - 600 IUs or 15mcg
Deficiency can occur for a number of reasons. Darker skin and sunscreen use inhibit the absorption of UVB rays needed for Vitamin D production. Sunscreen with SPF of 30 can reduce your absorption of sunlight by up to 95%. Skin needs to be uncovered and without sunscreen to absorb what is needed for Vitamin D production. If your lifestyle or your geography impedes your ability to be out in the sun, you should probably be getting your supply from food sources or supplementation.
Signs of Vitamin D deficiency
Effects of prolonged Vitamin D deficiency
Check your Vitamin D level as part of your health maintenance. It's likely that most of the world's population is deficient in this vital hormone. It's easy to reverse the deficiency if you know it's an issue. Knowledge is power.
