Vitamin D3 – Let the Sun Shine In

1. Why do we need Vitamin D3?
Vitamin D assists calcium in building strong teeth and bones as well as in maintaining bone mass.* Vitamin D also supports cellular function and supports the body’s immune system.*

2. What is the recommended daily dosage?
Vitamin D has certainly earned its place on the essentials list. And now doctors are becoming more concerned than ever about the public getting enough of this vital nutrient. It has been estimated that as many as three-quarters of U.S. teens and adults are deficient in Vitamin D.2 The Institute of Medicine suggested that individuals up to the age of 70 should have a daily allowance of 600 IU’s of Vitamin D. Those over 70 should have a daily allowance of 800 IU’s. Some adults may need even more Vitamin D.

3. What is the difference between Cholecalciferol (D3) and Ergocalciferol (D2)?
“Vitamin D3 is real vitamin D, for it is the same substance as what is produced in human skin in response to sun exposure.”1

Vitamin D2 is derived from plant sources and is not naturally produced within the body.

4. What are some causes of insufficient levels of Vitamin D?
There are some food sources of Vitamin D – egg yolk and cod liver oil being primary among them. The body also synthesizes Vitamin D from cholesterol when the skin is exposed to sunlight. Unfortunately, between extended work hours indoors, living in Northern regions, and slathering on sunscreen, most people are not getting enough sun.
