Expert: 50% of the World’s Population Deficient in Vitamin D

by Dr. Edward Group DC, NP, DACBN, DCBCN, DABFM Published on , Last Updated on


Vitamin D is an essential part of a healthy diet. The human body needs relatively large quantities of it in order to maintain bone density and metabolism, as well as general organ health.

The impact it has on the body’s overall well-being cannot be overstated. Over time, vitamin D deficiency doesn’t just weaken bones, it has also been shown to impede nerve function and mental cognition. It’s also important for maintaining a healthy heart and immune system.

Unfortunately, very few of us get the necessary amount of Vitamin D our bodies require. In fact, estimates are that over two-thirds of the the U.S. and European population is vitamin D deficient. And the figures are even worse in many other parts of the world.

How Much Vitamin D Does My Body Need?

The previous RDA recommendation is that adults up to age 50 consume at least 200 international units (IUs) each day. This number increases to 400 IU for adults between the ages of 51 and 70, and 600 IU for adults who are over age 70. However, these amounts changed in late 2010, when the Institute of Medicine released new recommended Vitamin D intakes. They recommend that healthy adults get 600 IU per day, and adults over the age of 71 should get 800 IU per day.

Despite these new recommended amounts, many experts now believe, myself included, that the current recommendations are grossly inadequate.

In fact, according to Dr. Anthony Norman, professor of biochemistry and biomedical sciences at the University of California, Riverside, and world renowned expert of vitamin D, the average adult should intake between 2,000 and 4,000 IU per day to maintain proper health [1].

If these new estimates are correct, then the average person isn’t just slightly lacking in vitamin D – They are severely deficient!

Not only that, but it also means that many of us who believe we are already getting enough are sorely mistaken. To further underscore the benefits of providing the body with sufficient levels of Vitamin D, Dr. Norman adds that that a number of studies indicate noticeable “reductions in incidence of breast cancer, colon cancer and type 1 diabetes in association with adequate intake of vitamin D, the positive effect generally occurring within five years of initiation of adequate vitamin D intake.”

Natural Sources of Vitamin D

Vitamin D Foods

Exposure to amounts of ultraviolet radiation from sunshine especially at sunrise and sunset, or artificial substitutes such as tanning or UV beds, trigger the human body’s natural ability to produce vitamin D. Other naturally occurring sources are somewhat scarce. Only a handful of foods are known to contain measurable quantities of vitamin D. These food sources primarily include different varieties of fish and fish oil.

However, as a vegetarian, I do not eat or recommend eating fish. My personal favorite is Shiitake mushrooms, as they are very high in vitamin d, as well as vitamins B1 and B2. Many fortified cereals and other grain products also contain a fair amount of D vitamins. Organic eggs are also high in vitamin D.

Is There A Better Way to Get More Vitamin D?

Considering the difficulties nearly all of us have getting even the current daily requirement, taking a vitamin D3 supplement like Suntrex D3 is a great way to conveniently fill the gap.

Suntrex D3 is a unique live source of D vitamin that more than meets the human body’s dietary needs and it is 100% vegetarian. Because it’s a liquid and not a pill or capsule, it does not contain any unnecessary fillers or binding agents.

    There is 50% daily value Vitamin D in my multi-vitamin, so I guess I’m still part of the 50% deficient.

    A numer of recent studies found that high blood levels of vitamin D may offer protection against colorectal cancer. Vitamin D has been also been linked with a number of other benefits, from bone and cardiovascular health to improved immunity, sleep and mood.

    I used to get patches of eczema every winter in spite of taking high quality supplements, extra fish oils and good diet, until I bumped up my intake of vitamin D to 4-5 thousand units a day – no more eczema!

    My advice on getting more Vitamin D… go outside! Actually, during winter, it can be tough for people who work in an office to even get outside for 10 minutes. One question about all these Vitamin D supplements, being recommended is what is the quality of the vitamins, and how clear is it that the vitamins are actually being absorbed into the body? Naturally sunlight is the best net.
