A new study suggests that vitamin E supplements may not actually protect women from cataracts.

The investigation by researchers during the Women's Health Study (WHS) shows that those women taking vitamin E supplements had similar rates of developing cataracts to those who did not take vitamin E.

Lead researcher Dr. William G. Christen and his colleagues studied the data of 39,876 professional women aged 45 or older.

Women took 600 IU of vitamin E every other day and 100 mg aspirin everyday for 10 years. Their histories of cataract, health and lifestyle factors were recorded.

The results revealed that after 6.5 years of having only vitamin E supplementation or with other antioxidant nutrients caused a minimal effect on the occurrence of cataracts in healthy patients.

The research was published in May 2008 issue of Ophthalmology, the journal of the American Academy of Ophthalmology.
