Vitamin D: It Matters
Vitamin D is important throughout life to help your body use calcium to build and maintain strong bones. It may also increase muscle strength to help prevent falls and broken bones in older adults.
Recommended Daily Vitamin D Intakes
| Age | Vitamin D in IU International Units) |
|---|---|
| Birth to 12 months | 400 |
| 1 to 70 years old | 600 |
| 71 years and older | 800 |
The American Academy of Pediatrics recommends 400 IU of vitamin D each day for infants from birth to 12 months. Vitamin D is found in formula or it is given as prescription drops (necessary for all breast-fed infants). Your health care provider may recommend more vitamin D than the above amounts.
Three ways to get Vitamin D
There are 3 ways to get vitamin D: from sunlight, food, and supplements.
Vitamin D and the Sun
The body makes vitamin D when skin is exposed to the ultraviolet light (UVB rays) from the sun. During the winter months in New York the UVB rays are not adequate to make enough vitamin D. In addition, as we age, our bodies are less able to make vitamin D from sun exposure. The most important factor that blocks the body's ability to make vitamin D, is the use of sunscreen to protect skin from sun damage. For all of these reasons, especially the importance of protecting your skin, it is recommended that people use sunscreen and get vitamin D from foods and/or supplements.
Nutrition Information about Vitamin D
There is limited but growing information available about the vitamin D content of foods. The USDA National Nutrient Database (www.nal.usda.gov) and food labels are the best resources for more information.

Supplemental Sources
It is very di cult for many individuals to get enough vitamin D from food Many children and adults need to take vitamin D as a supplement, including all breast-fed infants and infants taking less than 1 quart of formula/day Vitamin D comes in two sources, Vitamin D2 and Vitamin D3. Vitamin D2 is also called ergocalciferol, and comes from vegetarian sources. Vitamin D3 is also called cholecalciferol, and comes from animal sources. Vitamin D2 and vitamin D3 can both protect your bones.
Supplements Containing Vitamin D
- Multivitamins
- Calcium with vitamin D
- Vitamin D alone (Do not select vitamin D in combination with retinol sources of vitamin A*)
Vitamin D is available in various doses over the counter without a prescription or as a prescription. Speak to your health care provider to find out how much vitamin D you need and the best source for you.
Vitamin A: Get it from Colorful Fruits and Vegetables
- Retinol (a form of vitamin A found in foods of animal origin and in some supplements) may have a negative e ect on the skeleton However, beta-carotene and other carotenoids (forms of vitamin A found in darkly colored red, orange and green fruits and vegetables, as well as in some supplements) appear to be safe for the skeleton.
- It is wise to avoid foods high in retinol content, including cod liver oil and liver, even though they are sources of vitamin D. You can easily get enough vitamin A by eating several daily servings of fruits and vegetables high in carotenoids such as, carrots, cantaloupe sweet potatoes, and spinach.
* By reading the labels of supplements, you can find out the content and source of vitamin A. It is recommended to avoid combination vitamin D and A supplements, and to choose multivitamins that contain less than 80% of the Daily Value (DV) of vitamin A from retinol sources. Retinol sources may be listed on the supplement label as provitamin A, retinyl palmitate, vitamin A palmitate, retinyl acetate and vitamin A acetate.
