Vitamin D and cancer campaign launched today

SAN LUIS OBISPO, CA, September 6, 2011 – The Vitamin D Council, a nonprofit educational corporation based in California, launches their “Vitamin D and Cancer” campaign today, presenting 20 detailed summaries of the evidence on the role of vitamin D in preventing cancer. Epidemiologist Dr. William Grant prepared the evidence-based summaries. He is the founder of the nonprofit organization, Sunlight, Nutrition and Health Research Center (SUNARC) and serves as the Science Director for the Vitamin D Council.

Some researchers believe the link between vitamin D sufficiency and a decreased risk in cancer is promising. A randomized controlled trial found a 77% reduction in all-cancer incidence when the study group supplemented with 1100 IU/day of vitamin D plus 1450 mg/day calcium. Says Dr. Grant, “Based on various studies of UVB, vitamin D and cancer to date, it appears that global cancer burden can be reduced by 15-25% if everyone had vitamin D blood levels above 40 ng/ml.”

The summaries can be found under the “Health conditions” tab on the Vitamin D Council website, or more specifically at.................

The Vitamin D Council hopes the campaign will spread more awareness about the importance of vitamin D sufficiency and the dangers of vitamin D deficiency.

Top ten facts about vitamin D and cancer (presented in the summaries):

Many studies have found solar ultraviolet-B (UVB) and vitamin D associated with reduced risk of breast, colon, and rectal cancer.
A randomized controlled trial with 1100 IU/day vitamin D3 plus 1450 mg/day calcium found a 77% reduction in all-cancer incidence.
Geographical studies have found reduced risk in mortality rates for 20 types of cancer in regions of higher solar UVB doses.
Observational studies have found that the risk of breast, colon, and rectal cancer fall as vitamin D blood levels rise at least up to 40 ng/mL (100 nmol/L).
Mechanisms have been proposed to explain how vitamin D acts to reduce the risk of cancer from starting, growing, and spreading.
Those who develop nonmelanoma skin cancer may have produced enough vitamin D to reduce their risk of internal cancers.
Those with higher vitamin D blood levels at time of cancer diagnosis had nearly twice the survival rate of those with the lowest levels.
African-Americans have an increased risk of cancer in part due to lower vitamin D blood levels because of darker skin.
Higher UVB exposure early in life has been found associated with reduced risk of breast and prostate cancer.
Those diagnosed with breast, colon and prostate cancer in summer in Norway had higher survival rates than those diagnosed in winter.
