What Is Vitamin D And Why Do You Need It

Vitamin D is one of the 13 essential vitamins. However, vitamin D is unique in that your body is able to produce it from sun exposure. You have to consume all of the other vitamins through food or supplements your body cannot produce them on its own. Another unique trait of vitamin D is that before your body can use it, it must be converted into a hormone called calcitriol or activated vitamin D.

Vitamin D is one of the four fat-soluble vitamins, along with vitamins A, E, and K. These vitamins are absorbed better when consumed with high-fat foods, and they are stored in the liver and fatty tissue throughout the body.

While it has several functions, the most important role of vitamin D is to help your body absorb calcium from food passing through your small intestine and then regulate the amount of calcium and phosphorus in your bloodstream. The mineral calcium is crucial for strong, healthy bones, so without sufficient vitamin D, your bones will grow soft and weak. Vitamin D also helps your body maintain a strong immune system, and it plays a part in regulating cell growth and communication between cells.

Study Proves The Inadequacy Of Vitamin D2

A report published in The American Journal of Nutrition points out the very clear difference between Vitamin D3 and Vitamin D2, the latter, the form of vitamin D used in major preparations of prescriptions in North America.1 Vitamin D2 is in fact not the bioavailable equivalent of D3.

Vitamin D2, if given in high enough doses, prevents infantile rickets and is capable of healing adult osteomalacia. However, the inefficiency of vitamin D2 compared with vitamin D3, on a per mole basis, at increasing 25D is now well documented, and no successful clinical trials to date have shown that vitamin D2 prevents fractures.1

The study goes on to state that

ergocalciferol should not be regarded as a nutrient suitable for supplementation or fortification.1

Heres why. There are several biological mechanisms that contribute to the superior absorbability and efficacy of Vitamin D3. In the liver, thanks to a particular hepatic enzyme, Vitamin D3 is more readily metabolized into a bioactive form of D that is easily converted to its hormone form in the kidneys. It takes much longer to make this hepatic conversion with Vitamin D2.1

In fact, D2 and D3 are metabolized so differently that they result in the production of unique biologically active metabolites.1

Clearly, these forms of Vitamin D are simply not the same. Hence the studys conclusion that ergocalciferol should not be used as a supplement.

The Final Verdict On Vitamin D

Make Your Own Vitamin D Supplements for Pennies

No bones about it, the endocrinologists we interviewed agree with our dermatologist.

“Just being outdoors, you get a fair amount of sun exposure and some sun-related generation of vitamin D, says Dr. Insogna. Because skin cancer, particularly melanoma, can be such a devastating disease, it’s best to use sunblock when outdoors in strong sunlight for any prolonged length of time. Because this may limit the amount of vitamin D you get from sun exposure, make sure your diet includes sources of vitamin D from foods or supplements, he says.

Both your skin and your bones will thank you.

    Is Vitamin D Or D3 More Effective

    Vitamin D2 and D3 are absorbed into the bloodstream where they are metabolized by the liver into 25-hydroxyvitamin D2 and 25-hydroxyvitamin D3, otherwise collectively known as 25D or calcifediol. Calcifediol is the vitamin D complex circulating in your blood, and its levels directly reflect your bodys stores of vitamin D. Calcifediol is commonly referred to as the active form of vitamin D. When your doctor orders lab tests to check your vitamin D levels, they are measuring your calcifediol levels.

    There have been several studies comparing whether supplementation with vitamin D2 or D3 produces a higher blood level of calcifediol. A study published by the National Institutes of Health was conducted in elderly, post-menopausal women who had been identified as vitamin D deficient. It compared the effects of receiving a single high dose of vitamin D2 or vitamin D3 on calcifediol levels. The study concluded that vitamin D3 produced about twice the amount of circulating calcifediol in this patient population versus that of vitamin D2.

    In a separate clinical trial comparing a 10-week regimen of twice weekly 50,000 IU dosing of both vitamin D2 and vitamin D3 in demographically matched groups, vitamin D3 was also found to be superior in producing higher levels of 25D, or calcifediol.
