The Claim

Vitamin E and C supplementation has no effect on cancer risk in healthy male physicians, regardless of subgroup differences in age, smoking status, BMI, alcohol consumption, aspirin use, or family history of cancer.

Source: Vitamin E and C supplementation and risk of cancer in men: posttrial follow-up in the Physicians' Health Study II randomized trial.

Description
1 study reviewed
In plain English

Taking vitamin E and vitamin C supplements does not change the risk of developing cancer in healthy male physicians, even when considering differences in age, smoking, weight, alcohol use, aspirin use, or family history of cancer.

See the scientific wording

The lack of effect of vitamin E and C supplementation on cancer risk persists across subgroups defined by age, smoking status, BMI, alcohol consumption, aspirin use, and family history of cancer in healthy male physicians.

Why this might work

Taking vitamin E and C pills does not change how cells fix damaged DNA or stop abnormal cell growth, so cancer risk stays the same no matter a person's age, weight, smoking habits, or family history.

  1. Study: Vitamin E and C supplementation and risk of cancer in men: posttrial follow-up in the Physicians' Health Study II randomized trial.

    This big study gave thousands of men vitamin E or C pills for over 10 years and found that, no matter if they smoked, were overweight, drank alcohol, took aspirin, or had a family history of cancer, the vitamins didn’t lower or raise their cancer risk.
