Support With a Capital D

See what vitamin D can do for your health

Vitamin D is critical to making the most of calcium absorption. Without enough vitamin D, the body can't produce enough of the hormone calcitriol (active vitamin D), which leads to insufficient calcium absorption from the diet.

People get vitamin D from both the sun and certain foods, but research shows that most Americans are falling short. VIACTIV® Calcium Soft Chews can help supplement the vitamin D the body needs for bone health.

Here are some common ways to get vitamin D:


The sun stimulates the body to make vitamin D. However, many people are limiting their exposure to the sun and, as a result, limiting the body's production of vitamin D.


Food like eggs, some dairy products, fatty fish, and certain fortified foods contain vitamin D, but it may be difficult to meet the higher vitamin D levels that are now being recommended from foods alone.


Supplements, like VIACTIV® Calcium Soft Chews, are a delicious and convenient way to help get the recommended daily amount of vitamin D and calcium.

Are you at risk for vitamin D deficiency?

Getting adequate vitamin D from your diet is essential for strong bones and optimal health. You may be at risk for vitamin D deficiency if you:

  • Spend limited time in the sun
  • Live in higher latitudes
  • Are an adult aged 50 or older
  • Have dark skin

The Dietary Guidelines for Americans recommends that people with any of the above risk factors consume extra vitamin D from fortified foods and/or supplements. The best way to know if you are getting enough vitamin D is to ask your doctor to order a test to check your blood levels.

Vitamin D: for strong and healthy bones

The National Osteoporosis Foundation recommends adequate calcium and vitamin D on a daily basis as a key step in developing and maintaining healthy bones. Recently, higher levels of vitamin D have been shown to have an important impact on bone health.

Vitamin D2 and Vitamin D3

Vitamin D is available in 2 forms: D2 and D3. VIACTIV® Calcium Soft Chews contain vitamin D3. Both forms raise vitamin D levels in the blood, however, some research indicates that vitamin D3 may be more effective in raising and maintaining vitamin D levels long term.
