Antioxidant Supplements for Oxidative Stress
Oxidative stress describes an imbalance between free radicals and the body’s antioxidant defences. Vitamin C, vitamin E, selenium and zinc each contribute to the protection of cells from oxidative stress. Our top picks include four antioxidant nutrient products and a grape seed extract. A varied diet with plenty of fruit and vegetables remains the main source of antioxidants.

How to Choose
Food first: aim for five portions of fruit and vegetables a day in a range of colours, and choose whole grains, nuts and olive oil. Then use one antioxidant supplement. Avoid taking several high-dose antioxidants together; more is not better. Not smoking and limiting alcohol reduce oxidative stress far more than a pill.
What Is Oxidative Stress?
Free radicals are reactive molecules made during normal metabolism and boosted by smoking, pollution, UV light, alcohol, infections and intense exercise. When the body’s antioxidant defences cannot keep pace, cells and tissues can be damaged, which is linked with ageing and many chronic diseases. Oxidative stress is a research concept and not a diagnosis.
When to See a Doctor
See a doctor if you have persistent tiredness, frequent infections, chronic disease symptoms, or want to check your nutrient status. Do not use antioxidant supplements to treat a diagnosed disease without your doctor. Stop smoking with medical help if needed.
What Supplements Can and Cannot Do
Antioxidant nutrients contribute to the protection of cells from oxidative stress as part of a balanced diet. High-dose supplements have not been proven to prevent disease, and some (such as high-dose vitamin E or beta-carotene) may be harmful for some people.
Precautions and Interactions
- Vitamin E: check with a doctor if you take blood thinners, and do not exceed the label dose.
- Selenium: do not combine with other selenium supplements. Long-term intake above 255 mcg a day is not advised.
- Grape seed extract: ask a doctor first if you take blood thinners.
- Vitamin C at high doses can cause stomach upset and kidney stones in susceptible people.
- Not for pregnancy or breastfeeding without medical advice.
