Vitamin D Research
Special, 63-minute, “Vitamin D Only” Audio Files The following files contain the very tightly edited “Vitamin D only” audio of our original podcast. These files have all of the non-Vitamin D (Security Now!) content removed, and they were further streamlined to remove all other audio annoyances. The resulting 63-minute audio is perfectly suited for sharing the Vitamin D podcast content with others who are not Security Now! listeners.
If it bears out, it will challenge one of medicine's most fundamental beliefs: that people need to coat themselves with sunscreen whenever they're in the sun. Doing that may actually contribute to far more cancer deaths than it prevents, some researchers think. The vitamin is D, nicknamed the "sunshine vitamin" because the skin makes it from ultraviolet rays. Sunscreen blocks its production, but dermatologists and health agencies have long preached that such lotions are needed to prevent skin cancer.

Exciting new research conducted at the Creighton University School of Medicine in Nebraska has revealed that supplementing with vitamin D and calcium can reduce your risk of cancer by an astonishing 77 percent. This includes breast cancer, colon cancer, skin cancer and other forms of cancer. This research provides strong new evidence that vitamin D is the single most effective medicine against cancer, far outpacing the benefits of any cancer drug known to modern science. The study involved 1,179 healthy women from rural Nebraska. One group of women was given calcium (around 1500 mg daily) and vitamin D (1100 IU daily) while another group was given placebo .
New research shows vitamin D slashes risk of cancers by 77 perce
Editor's Choice Main Category: Nutrition / Diet Also Included In: Dermatology ; Public Health Article Date: 24 Aug 2009 - 1:00 PDT email to a friend printer friendly opinions Vitamin D is a steroid vitamin, a group of fat-soluble prohormones, which encourages the absorption and metabolism of calcium and phosphorous. People who are exposed to normal quantities of sunlight do not need vitamin D supplements because sunlight promotes sufficient vitamin D synthesis in the skin. Five forms of vitamin D have been discovered, vitamin D 1 , D 2 , D 3 , D 4 , D 5 .
What Is Vitamin D? What Are The Benefits Of Vitamin D?
Introduction Vitamin D is a fat-soluble vitamin that is naturally present in very few foods, added to others, and available as a dietary supplement.
Dietary Supplement Fact Sheet: Vitamin D
Classically vitamin D3 has been shown to be one of the most important biological regulators of calcium metabolism through stimulating the absorption of calcium from food across the intestine and participating in the incorporation of the absorbed calcium in to the skeleton. It has become increasingly apparent since the 1980s that 1a,25(OH)2D3 also plays an important multidisciplinary role in tissues not primarily related to mineral metabolism, e.g. the hematopoietic or blood system, effects on cell differentiation and proliferation including important interactions with keratinocytes and cancer cells, and participation in the processes of parathyroid hormone and insulin secretion.

Vitamin D Deficiency Leaves Millions of Children and Adults at Risk For Numerous Diseases and Disorders In a review article published in The New England Journal of Medicine July 18th, Dr. Holick explores the nature of vitamin D deficiency and concludes it to be one of the most commonly unrecognized medical conditions, a condition that leaves millions at risk of developing not only osteoporosis and fractures but also numerous serious and often fatal diseases, including several common cancers, autoimmune diseases, infectious diseases and heart disease.

Vitamin D Vitamin D is a fat-soluble vitamin that is essential for maintaining normal calcium metabolism (1) . Vitamin D 3 (cholecalciferol) can be synthesized by humans in the skin upon exposure to ultraviolet-B (UVB) radiation from sunlight, or it can be obtained from the diet. Plants synthesize ergosterol, which is converted to vitamin D 2 (ergocalciferol) by ultraviolet light (2) .
