Why Vitamin D?

What is vitamin D? What is vitamin D good for? Vitamin D has long been known for supporting normal bone development and muscle strength, and for helping to promote overall bone health. The most conclusive information about the benefits of vitamin D  and normal vitamin D levels comes from evidence in bone and teeth development. Vitamin D helps the body use calcium and phosphorus to build and maintain strong bones and teeth. It helps our bodies absorb calcium and phosphorus from the food that we eat. So vitamin D works hand in hand with other nutrients to help promote bone health, and is essential for calcium uptake.  

Vitamin D is important in supporting a healthy skeletal system by allowing the absorption of calcium and phosphorous, and therefore:

  • Helping children to develop strong bones.
  • Helping to contribute to bone health in adulthood.
  • Helping to build strong teeth, especially the enamel, which is actually the hardest substance in the body.
  • Muscles contain vitamin D receptors. Muscle strength and function have been linked to vitamin D. [i]

What about vitamin D in other areas?

Research suggests that there could be an association of vitamin D with other functions in the body. There are many different types of tissues in the body that contain vitamin D receptors (VDRs) and would therefore have the ability to respond to circulating vitamin D in the body[ii]. There are different opinions about the importance of vitamin D as research continues to look at the extra-skeletal functions of vitamin D. More evidence is needed to say definitively what role vitamin D plays throughout the body and what other vitamin D benefits are. Studies continue to look at relationships with vitamin D and immune regulation, promotion of cell differentiation, and regulating cell growth. Areas of active vitamin D research include pregnancy, cardiovascular and brain function.

It would take 40 eggs or 10 glasses of milk a day to receive 1000 IU of vitamins.. SPF 8 has been reported to reduce production of vitamin D by 95%..

Why take a vitamin D supplement?

Vitamin D supplements are a nutrient needed by those who do not get enough vitamin D either through other vitamin D sources, such as exposure to ultraviolet light, or food sources of vitamin D. 

In nature, there are very few vitamin D foods, and foods high in vitamin D. Many of the common food sources of vitamin D contain very small amounts of vitamin D.

During summer, many people are advised to avoid direct sun exposure because of the risk of skin cancer. Using sunscreen blocks skin from producing vitamin D.

The American Academy of Dermatology (AAD) recommends getting vitamin D safely through a healthy diet, that may include vitamin D supplements. Vitamin D supplements are safe to use and equally as effective as the sun in maintaining healthy levels of vitamin D.

Ddrops® are a great vitamin D option for those looking to take a vitamin D supplement in just one drop.

Do you need a vitamin D supplement?

Do you live north of the line connecting San Francisco to Philadelphia?

Do you rarely get outside daily between 10 am -2 pm for a 15-minute (or more) walk in the sun?

Do you usually use sunscreen to protect your skin when you are outside on a sunny day?

Do you have dark or pigmented skin?

Do you spend over 4 hours daily inside in front of a computer, and/or watching TV?

Do you rarely eat oily fish (swordfish, salmon, tuna, sardines)?

Do you drink less than 2 glasses of vitamin D fortified milk daily or dairy products (yogurt)?

If you answered YES to many of these questions, you might consider speaking with your healthcare professional about your need for vitamin D.
