Abstract

A recent study published in the New England Journal of Medicine investigated this potential hazard in 3,322 men between the ages of 49 and 51. Serum levels of vitamin A and beta carotene were measured and these individuals were followed for 30 years. 266 men experienced bone fractures over this time period. During these 30 years, researchers found that the risk of bone fractures was higher among the men with higher serum levels of vitamin A. The levels of beta carotene were not associated with fractures. The authors of this study concluded that the amounts of supplementation of vitamin A need to be reassessed in many Western countries.
