Can you take Omega-3 (Fish Oil) and Vitamin E together?

Watch the combined dose

Fine at normal doses, but both mildly thin the blood at high doses — be careful if you take anticoagulants or have surgery coming up.

🕑 How to time them

Same fatty meal is fine — both are fat-soluble. Keep vitamin E modest (large doses have no proven benefit) and mention the combo before any surgery.

Fine at normal doses, but both mildly thin the blood at high doses — be careful if you take anticoagulants or have surgery coming up. Omega-3 (Fish Oil) is typically taken for heart, brain, and eye health; anti-inflammatory, while Vitamin E is used for antioxidant, protects cell membranes — different jobs, so people often end up with both in the cabinet.

For context: a typical daily amount of Omega-3 (Fish Oil) is 250–500 mg*, and the upper limit for Omega-3 (Fish Oil) is ~3,000 mg. A typical daily amount of Vitamin E is 15 mg, and the upper limit for Vitamin E is 1,000 mg.
