LARGE daily doses of vitamin D can cut your risk of cancer by up to half, it has been claimed.
Researchers found the protection came from the vitamin's D3 form.
They said people need to take 1000 international units (IU) of D3 daily - half the safe upper limit set by the US National Academy of Sciences.
More than 2000 IU a day can lead to liver and kidney damage.
Professor Cedric Garland led the US study which reviewed investigations into the effects of vitamin D on breast, prostate, colon andovarian cancer Action He said: "Public health action is needed. "We now have proof the incidence of these cancers can bereduced dramatically by increasing the public's intake of vitamin D."
D3 is normally produced in the skin by the action of sunlight.
But it can also be obtained from food sources and supplements.
Professor Garland said: "You have to work fairly hard to reach 1000 IU a day.
"Sun exposure has its own concerns and limitations. We recommend no more than 15 minutes of exposure daily over 40 per cent of the body, other than the face, which should be protected from the sun."
However, a leading cancer charity are cautious about the vitamin D claims.
Sara Hiom, of Cancer Research UK, said: "The evidence is complex and confusing. Further research is needed
