Vitamin E
Also called: Tocopherols, tocotrienols, d-alpha-tocopherol
A fat-soluble antioxidant that helps protect cell membranes from damage. It has a mild blood-thinning effect, which matters if you take other blood thinners.
Commonly used for

- Skin health
- Menstrual cramps (some studies)
- Poor fat absorption, such as with celiac disease or IBD
Found naturally in
- Sunflower seeds
- Almonds and hazelnuts
- Wheat germ oil
- Spinach
- Avocado
Label red flags
- 'dl-alpha-tocopherol' on the label, which means the synthetic form
- High-dose vitamin E taken long term without a clear reason. Some studies link this to more harm than benefit.
Check with a provider
- Taking a blood thinner or antiplatelet drug (warfarin, apixaban, clopidogrel, aspirin), since vitamin E can raise bleeding risk
- A bleeding or clotting disorder, low vitamin K, or a history of stroke
- Upcoming surgery or dental work. Your care team may ask you to stop beforehand.
- In cancer treatment. Check with your oncology team first.
