Vitamin E Supplementation And Cataract: Randomized Controlled Trial
| Effect | None |
| Trial Design | Double blind |
| Trial Length | 6+ Months |
| Number of Subjects | 1038 |
| Sex | Both Genders |
| Age Range | 45-64, 65+ |
In persons aged 55-80 with either early signs or no signs of cataract formation, supplementation of 500IU vitamin E (as alpha-tocopherol) daily for four years has failed to cause significant protective effects relative to placebo.
All cause mortality done in a secondary analysis did not differ between groups, nor did any reported side effects.
