How they work
Antioxidants prevent cell damage by counteracting free radicals.
Effect on Disease
Research on Antioxidants and disease prevention has shown mixed results.
Berries & Fruit
Your body makes vitamin A with beta-carotene, commonly found in carrots.
Found in all sorts of fruits, Vitamin C is a very commonly consumed antioxidant.
Vitamin E can be found in nuts and seeds.
1. Long Term Antioxidant Use May Show Benefits
One study found that taking beta-carotene, an antioxidant from carrots, over 15 years led to more "brain power" as measured by cognitive testing.
2. More Vitamin E = More Intelligence?
A recent study found people who had more vitamin E, commonly found in fruits and nuts, also performed better on intelligence testing.
3. More Study is Needed
We need more research before we know for sure whether antioxidants can boost the brain. The research on antioxidants is still thin, and inconsistent. Some studies have shown negative results, particularly with short term dosing.
A trial showed that those who were given antioxidants over 18 years had more "brain power" than those who weren't. Scientists measured this through cognitive testing. But, short term antioxidant use, over 5 years, did not show benefits.
Researchers found that people with higher levels of Vitamin E in their blood tended to perform better on memory and verbal tests.
This study shows an interesting relationship between the amount of Vitamin E in your blood and your brain's performance on Cognitive Testing. However, this study doesn't necessarily show that Vitamin E is better for your brain, as it only shows a correlation.
