CWeak evidence, or evidence againstVitamin
The short answer
One of the clearer cases where the supplement failed to reproduce what the food it came from is associated with.
Who this is actually for
People with a diagnosed deficiency, which is rare outside fat malabsorption disorders.
What it is legally allowed to claim
Quoted from the EU register of authorised health claims, Regulation (EU) 432/2012. A product may only make these claims if it supplies enough of the nutrient to qualify.
- Vitamin E contributes to the protection of cells from oxidative stress
How much is too much
EFSA tolerable upper intake level 300 milligrams per day for adults.
Cautions and interactions
High-dose supplementation has been associated with increased bleeding risk and, in some trials, worse outcomes. Avoid with anticoagulants unless supervised.
Ask a pharmacist before you start anything. Interactions with prescribed medicines are the most common way supplements cause harm, and they are easy to check. Bring the actual packet, or a photo of the ingredients panel, because doses and forms vary enormously between products. Nothing here is a substitute for advice about your own situation.
