Selenium + Vitamin E

Can you take Selenium and Vitamin E together?

SynergyMechanism-based

Yes, at moderate doses — but high doses of either haven't prevented cancer.

What to do. Stick to modest doses; don't megadose for cancer prevention.

Mechanism

Complementary antioxidant systems

Selenium-dependent glutathione peroxidase and vitamin E protect membranes in complementary ways. In the SELECT trial, 400 IU vitamin E and 200 mcg selenium did not prevent prostate cancer, and vitamin E alone slightly increased it.

Evidence: Mechanism-based — Plausible biological mechanism with little direct human outcome data.
