About Vitamin D Day

Vitamin D deficiency is a world problem.

This November 2nd is Vitamin D Day!

Vitamin D Day is a day to recognize vitamin D deficiency as a world problem.

Researchers agree that at least one third of the world is deficient in vitamin D, and some scientists even think a greater percent of people are deficient in vitamin D.

Why are so many people deficient, you might ask? It’s simple really. We get vitamin D from sun exposure. And now, more than ever, the world’s population lives an indoor lifestyle, avoiding the sun daily.

Doctors are beginning to discover that vitamin D deficiency is a risk factor for many diseases, including heart disease and cancer.

Furthermore, they’re discovering that vitamin D deficiency may make some diseases more severe, like respiratory diseases and autoimmune diseases like multiple sclerosis and lupus. And they’re discovering that vitamin D can be an important piece in the treatment of some illnesses and diseases, including multiple sclerosis, cystic fibrosis, asthma and many other diseases!

Please take the time and learn about vitamin D deficiency this November 2nd, and share what you know with others. Learn, educate and participate; let’s get the word out!

“Vitamin D deficiency is a global pandemic that has serious health consequences for children and adults. Improvement in the world’s vitamin D status could significantly reduce risk of many chronic illnesses including cardiovascular diseases, type II diabetes and many deadly cancers as well as infectious diseases including upper respiratory tract infections, influenza and tuberculosis.”

-Michael Holick, MD, PhD

Professor of Medicine, Physiology and Biophysics at Boston University School of Medicine

Learn. Educate. Participate. This global issue starts with better awareness.

Step one: Learn more about vitamin D

Eight key things to know about vitamin D:


1. Vitamin D comes from sun exposure, not your diet.

When you expose your skin to the sun, your body makes vitamin D, lots of it. On the other hand, there isn’t much vitamin D found in foods. This means that getting enough vitamin D depends on getting frequent and moderate sun exposure, not eating a balanced diet.


2. Scientists and doctors agree that at least a third of the world is deficient in vitamin D.

Some scientists think even a greater percentage are deficient. This is because we live in an indoor society, more so now than ever before in human history.

3. If you don’t get frequent moderate sun exposure or take a vitamin D supplement, you’re likely deficient in vitamin D.

Some people get tested for vitamin D by their doctors and are shocked to find out they’re deficient. But unless you get frequent moderate sun exposure or take a supplement, it shouldn’t come as a surprise at all. These are the only reliable ways to get the vitamin D your body needs. While there is a little bit of vitamin D in fish and fortified milk, there isn’t enough to make sure you’re sufficient in vitamin D.

4. Moderate midday sun exposure is the best for making vitamin D.

In order to make vitamin D, the sun needs to be high up in the sky, high enough so that your shadow is shorter than you. If your shadow is longer than you, the sun isn’t intense enough to help your body make vitamin D. Midday sun exposure is best; this is when the sun is high and your shadow is shorter than you are.


5. You don’t need to burn to make vitamin D.

To make good amounts of vitamin D, you should spend half the time out in the sun that it would take for your skin to turn pink.


6. Vitamin D supplements are a good option in the wintertime to get the vitamin D you need.

In the northern hemisphere, the sun starts focusing more on the southern hemisphere. The sun’s rays strike the northern hemisphere at a different angle, an angle that isn’t quite as intense as during the summer. In consequence, your body has a harder time making vitamin D in the winter compared to the summer. The further north you live, the more difficult it is to make vitamin D in the winter.

Remember you can always check to see if you’re making vitamin D by looking at your shadow. If it’s longer than you, you aren’t making much vitamin D. And in the winter, your shadow is often longer than you.

Have no fear that you can’t make vitamin D! Vitamin D supplements are a good option in the wintertime. Low-pressure sunbeds and UV light units are also options to help you make vitamin D during the winter.


7. Vitamin D is important for many things, including your bones, heart, respiratory system, brain, and likely cancer prevention.

Scientists are still discovering the effects of vitamin D on disease prevention, but researchers believe it may play a central role in preventing autoimmune diseases like multiple sclerosis and type I diabetes, preventing cancers like breast and colon, and keeping the heart healthy, by influencing muscle function and hormones involved in heart health.


8. Consider getting tested for vitamin D, to see if you’re getting enough.

Vitamin D tests are pretty easy. You can ask your doctor to add it to your next routine blood panel, or you can order a finger prick test online.

While not all doctors agree how much vitamin D you need, a group of 42 of the world’s top vitamin D researchers think the optimal vitamin D level is between 100-150 nmol/l, a level the majority of northern populations fall well below.
