Vitamin D May Cut Cancer Risk, Study Says
Tuesday June 12, 2007
A study published online last Friday in the American Journal of Clinical Nutrition, has found that vitamin D may reduce your risk of breast and other cancers.
Research into the link between vitamin D and cancer prevention dates back decades to observations that cancer rates were lower among people living in southern latitudes compared to similar groups in northern latitudes, since sunshine is a source of vitamin D. It's also found naturally in oily fish, such as salmon and tuna, and in fortified foods such as milk and some cereals.
The Canadian Cancer Society has since released new recommendations that, in consultation with a health-care provider, adults in Canada take 1,000 IU of vitamin D a day in the fall and winter, and that people with higher risk of vitamin D deficiency (such as people who spend little time outdoors and those with darker skin) take 1,000 IU of vitamin D supplements year-round.
Since then, there has been a spike in vitamin D sales. The American Cancer Society has not made a similar recommendation based on the study. Read the article: Vitamin D May Cut Cancer Risk, Study Says

Risk assessment for vitamin D Shows the tolerable Upper Limit for Vitamin D should be raised as No Observable Adverse Events have ever been recorded under 10,000iu/d.
The urgent need to recommend an intake of vitamin D that is effective shows all the World’s leading experts on Vitamin d are agreed that current official recommendations for Vitamin D understate the need for this substance and a level that is more close to meeting the body’d daily needs should be adopted as soon as possible.
I have a question about the Vitamin ‘D’. Is there risk of cancer due to deficiency of Vitamin ‘D’ or Is there any developing(initial stage) cancer symptoms lead to get deficiency of Vitamin ‘D’. I appreciate it if anyone can clarify this. Thank you.
The Vitamin D deficiency/insufficiency situation arises from a failure to spend sufficient time outside under direct exposure to sunshine.
It may also arise as a result of wearing sunblock, sunscreen, sun protection factor cosmetics ALL the time. You only have to have full body sun exposure for around 10-20 minutes to make sufficient Vitamin D3 for your daily needs. Heaney has shown healthy bodies use between 3000 and 5000iu daily. But he has also shown that men working outdoors all day in Omaha over the year average only 2800iu daily. This isn’t sufficient to keep them at optimal status throughout the year. We therefore need to use an EFFECTIVE amount of supplement.
Most cancers thrive in vitamin d insufficient bodies. For each skin cancer death from excessive sun exposure 30 people die from those cancers that thrive in vitamin d insufficient bodies.
