A new study suggests that, taking high doses of vitamin E supplements may increase the risk of lung cancer. The US study of 77,000 people found taking 400 milligrams per day long-term increased cancer risk by 28% - with smokers at particular risk.
The researchers followed people aged between 50 and 76 for four years and looked at their average daily use of vitamin C and folic acid, and vitamin E supplements. Over the course of the study, 521 people developed lung cancer.
Smoking, family history and age all had unsurprisingly strong links to cancer risk. And while neither vitamin C or folic acid use had any effect on lung cancer risk, vitamin E use did.
The researchers extrapolated their findings, and concluded that over a decade, there was an additional 7% increase in risk for every 100 milligrams taken per day. The researchers also warned about similar risks of excessive beta-carotene use. Link
