Vitamin D Deficiency: Are You At Risk

Vitamin D and Calcium

Vitamin D deficiency occurs when you are not getting the recommended level of vitamin D over time. Certain people are at higher risk for vitamin D deficiency, including:

  • People who spend little time in the sun or those who regularly cover up when outdoors
  • People living in nursing homes or other institutions or who are homebound
  • People with certain medical conditions such as Celiac disease and inflammatory bowel disease
  • People taking medicines that affect vitamin D levels such as certain anti-seizure medicines
  • People with very dark skin
  • Obese or very overweight people and
  • Older adults with certain risk factors.

Talk to your healthcare provider if you have any of these risk factors. If you have osteoporosis and also have a vitamin D deficiency, your healthcare provider may temporarily prescribe a high dose of vitamin D to bring you up to a healthy level.

What’s The Difference Between Vitamin D And D3

Vitamin D3, or cholecalciferol, is one of the forms of vitamin D. Both D2 and D3 need to be converted by the liver and then by the kidneys into the main form of vitamin D that circulates in your body. But D3 appears to more effectively raise our levels of active vitamin D than D2)which is why you may have heard it suggested by everyone from healthcare providers to wellness blogs.

A Complete Osteoporosis Program

Remember, a balanced diet rich in calcium and vitamin D is only one part of an osteoporosis prevention or treatment program. Like exercise, getting enough calcium is a strategy that helps strengthen bones at any age. But these strategies may not be enough to stop bone loss caused by lifestyle, medications, or menopause. Your doctor can determine the need for an osteoporosis medication in addition to diet and exercise.

Vitamin D3 Is More Effective At Improving Vitamin D Status

Vitamin D2 and D3 are not equal when it comes to raising your vitamin D status.

Both are effectively absorbed into the bloodstream. However, the liver metabolizes them differently.

The liver metabolizes vitamin D2 into 25-hydroxyvitamin D2 and vitamin D3 into 25-hydroxyvitamin D3. These two compounds are collectively known as calcifediol.

Calcifediol is the main circulating form of vitamin D, and its blood levels reflect your bodys stores of this nutrient.

For this reason, your health care provider can estimate your vitamin D status by measuring your levels of calcifediol .

However, vitamin D2 seems to yield less calcifediol than an equal amount of vitamin D3.

Most studies show that vitamin D3 is more effective than vitamin D2 at raising blood levels of calcifediol (

If you are taking vitamin D supplements, consider choosing vitamin D3.

Summary Vitamin D3 appears to be better than D2 at improving vitamin D status.

Is Vitamin D Deficiency An Epidemic No Its Not

Based on the United States Dietary Association and National Health and Nutrition Surveys , the bulk of the population is not vitamin D-deficient. The population we tend to see vitamin D deficiency inand its typically in wintertimeare breastfed infants. Breast milk doesn’t have much vitamin D in it. That’s what spurred a recommendation from the American Academy of Pediatrics that every breastfed infant be given vitamin D . But if infants aren’t given multivitamin drops, they need to be given 200 IU a day of vitamin D for the first two months of life and 400 units a day afterwards until theyre drinking formula or milk, which are each fortified with vitamin D.

How Can I Help Prevent Vitamin D Deficiency

The goals of treating and preventing the lack of vitamin D of treatment and prevention are the sameto reach and keep an adequate level of vitamin D in the body. Your healthcare provider will let you know if you need to take or keep taking vitamin D supplements. If so, they will also let you know how much you should take. You might also want to consider:

Eating more foods that contain vitamin D: See the vitamin D food sources table included in this article. Keep in mind that foods alone usually don’t meet the daily recommended levels of vitamin D.

Getting some exposure to sunshinebut not too much: Exactly how much sun exposure is needed isnt clear. 10 to 15 minutes of sun exposure two to three times a week to the face, arms, legs or back may be all that is needed to absorb a suitable amount of vitamin D. You might need more sun exposure if:

  • You are older.
  • You have a darker skin color.
  • You live in northern climates.

The use of sunscreen, and standing behind a window, prevents vitamin D from being produced in the skin. However, you should remember that too much sunshine increases the risk of skin cancer and ages the skin. That is why taking an appropriately dosed D supplement is far safer than intentionally getting routine sun exposure.
