Supplements / SOURCE BRIEF

Antioxidant does not automatically mean beneficial.

Evidence overviewSource dated Not specifiedCurated Sep 21, 2026

What to know

Findings about antioxidant-rich foods do not automatically transfer to concentrated supplements. NCCIH reports that evidence does not support antioxidant supplements for preventing cancer or cardiovascular disease, and some high-dose products have caused harm.

Points to carry forward

  • Match the product and outcome to the actual research.
  • Review supplements with the team managing any existing treatment.

Keep this in mind

There are condition-specific exceptions, including certain eye-disease formulas. Those findings do not justify a general anti-aging supplement stack.

A question to carry with you

Is the claim based on eating a food, taking a supplement or a laboratory mechanism?
