Is your vitamin D supplement unnecessary?

If your diet isn’t rich in dairy or you haven’t been in the sun lately, you may worry you are vitamin D deficient. But not everyone needs a vitamin D test, according to the Endocrine Society.

Vitamin D is essential. It keeps your bones strong, reduces inflammation and boosts your immune function. The average adult needs 15 micrograms (600 IU) of vitamin D a day, often attained through food.

So, should you consider getting a vitamin D test or taking a vitamin D supplement?

“Many earlier studies showed an association between an individual’s vitamin D levels and the risk of developing a variety of common disorders, which is why testing and supplementation is so popular,” explains Dr. John Brill, the vice president of population health sciences & research at Advocate Health Care and Aurora Health Care. “However, further research has not found that routine testing and supplementation improve overall health. That is why insurance will generally not cover routine tests or testing for non-specific symptoms, like fatigue.”

Certain populations are at an increased risk for vitamin deficiency and can benefit from vitamin D supplementation without the need for testing, according to the guidelines:

• Pregnant women. Supplementation can reduce your risk of preeclampsia and pre-term birth.
• People diagnosed with prediabetes. Studies show it can prevent the progression of the disease.
• People aged 75 or older. As you age, your nutrient absorption becomes impaired. Your aged skin is also less likely to absorb vitamin D from the sun.
• Children aged 18 and younger. Breastfed babies and children who are picky eaters may not get the recommended daily intake of vitamin D.

Dr. Brill says testing is recommended if you have symptoms of low calcium levels or a bone or endocrine condition.

So, unless you are in an at-risk population or are experiencing symptoms related to vitamin D deficiency, consuming more than the recommended dose of vitamin D isn’t going to benefit your health. Plus, it’s best to get nutrients naturally by eating a balanced diet.
