Research Question:
Swallowing of vitamin E reduces the chance of getting a heart attack?
Study Design:
This overview article contained 16 Rcts. The dosage ranged between 33 and 800 IU of vitamin e. the follow-up duration ranged between 0.5 and 9.4 years.
1 IU of vitamin E is approximately:
- 1 mg dl-α tocopherol acetate
- 0.91 mg dl-α tocopherol
- 0.67 mg d-α tocopherol (vitamin E in people's mouth)
- 1.12 mg dl-α tocoferolwaterstofsuccinaat
Results and conclusions:
The researchers found that swallowing vitamin E the chance of getting a heart attack significantly with 18% [RR = 0.82, 95% CI = 0.70-0.96, p = 0.01] reduced.
The researchers found that swallowing vitamin E the chance of getting a fatal heart attacks significantly with 16% [RR = 0.84, 95% CI = 0.73-0.96, p = 0.01] reduced.
The researchers concluded that swallowing 33-800 IE (22.11-536 mg) vitamin a day, reduced the risk of getting a heart attack. However, this reduced risk disappeared when vitamin E was combined with other antioxidants.
