The Claim
People often believe that because vitamin E is a natural antioxidant, it can be taken in high doses without any adverse effects.
Origin
This misconception is partly due to the general perception that vitamins, as natural compounds, are inherently safe regardless of the dose.
What Science Says
Modern research, including reviews and RCTs, shows that high doses of vitamin E can lead to adverse effects, including an increased risk of hemorrhagic stroke. The recommended upper limit for vitamin E intake is set to minimize such risks. Studies consistently indicate the importance of adhering to recommended dosages.
Verdict
Mostly False
