Increased intakes of vitamin C may increase the risk of developing cataracts in some elderly people, according to a new study.

Findings from 24,593 Swedish women aged between 49 and 83 indicated that vitamin C use was associated with a 25 per cent increase in the incidence of cataracts. Among the older women – over the age of 68 – vitamin C supplements were associated with a 38 per cent increase in the risk of cataracts, report the researchers in the American Journal of Clinical Nutrition​.

The findings were further complicated in women on hormone replacement therapy, where the supplements were associated with a 56 per cent increase in cataracts.

“Our results indicate that the use of vitamin C supplements may be associated with higher risk of age-related cataract among women,”​ concluded the researchers.
