Some important facts about Vitamin D

by Dr. Maurice Leibman on December 4, 2010

Vitamin D

  • Vitamin D is an essential nutrient in the prevention of osteoporosis.
  • Vitamin D3 is the Vitamin D of choice.
  • A chronically low Vitamin D will result in reduced calcium absorption and that may result in mild secondary hyperparathyroidism and increase bone loss.
  • Don’t rely on sunlight

The influence of dietary Vitamin D is minimal and most circulating Vitamin D is derived from sunlight, but dermatologist recommend we stay out of the sun!  The amount of exposure needed to achieve adequate Vitamin D status depends on latitude, altitude, time of year and day, weather, age, skin pigmentation, clothing, activity, and amount of skin irradiated.

  • Vitamin D insufficiency has been associated with colon rectal cancers, diabetes, multiple sclerosis, impaired immune response, and breast cancer. Ask for your Vitamin D level to be checked and shoot for 75 ng/ml or higher!

The recommended Vitamin D intake is 400-1000 IU daily for low-risk adults younger than 50 years and up to 2000 IU daily for high-risk and older adults.
