A little context matters
When More Isn't Better
High-dose vitamin E supplements can increase bleeding risk and may interact with anticoagulant or antiplatelet medicines.
Food and supplements are not the same thing. Supplements can deliver much larger doses. Medications, pregnancy, kidney or liver function, allergies, and other health circumstances can change what is appropriate.
