What Are Antioxidant Supplements?

Antioxidant supplements are dietary products that provide vitamins, minerals and plant compounds which help protect cells from oxidative stress. Oxidative stress is caused by free radicals – unstable molecules that are naturally formed in the body and can increase due to factors such as pollution, stress, intense exercise or an unbalanced diet. Antioxidant supplements may contain vitamin C, vitamin E, selenium, zinc, coenzyme Q10, alpha-lipoic acid, resveratrol, green tea extract and other phytonutrients. They are usually available as capsules, tablets, softgels, powders or liquid forms with clearly defined daily dosages and are designed to complement a varied diet rich in fruit and vegetables.

Benefits of Antioxidant Supplements

Antioxidant supplements help support the body’s natural defence system by neutralising free radicals and protecting cells from oxidative damage. Vitamins C and E, together with minerals such as zinc and selenium, contribute to the protection of cells and support normal immune function. Coenzyme Q10, alpha-lipoic acid and certain plant extracts are often used to support energy metabolism and overall vitality. As part of a healthy lifestyle, antioxidant supplements may help maintain skin health, support cardiovascular and eye health and contribute to long-term wellbeing, especially during periods of increased physical or emotional stress.

Uses of Antioxidant Supplements

Antioxidant supplements are often chosen by adults who want to support their immune system, skin, general health or recovery after demanding periods. They can be used alongside a diet rich in colourful fruit, vegetables, nuts and seeds, during seasonal changes, intense training blocks or times of high workload. Many antioxidant formulas combine several nutrients in one product, while others focus on a single ingredient such as vitamin C or resveratrol. On our category page you can explore a wide range of antioxidant supplements and choose products that best match your goals, lifestyle and daily routine.

Antioxidant Supplements: Side Effects and Overdose

Antioxidant supplements are generally well tolerated when used according to the instructions, but, as with any dietary supplement, individual reactions are possible. Some people may experience mild digestive discomfort, headache or allergic symptoms depending on personal sensitivity and the product’s full ingredient list. Excessive intake of certain antioxidants, especially fat-soluble vitamins such as vitamin A or very high doses of vitamin E, may cause unwanted effects or interfere with the action of medications. It is important not to exceed the recommended daily dose stated on the packaging and to consider total intake from food and other supplements. People with chronic illnesses, those taking prescription medicines, as well as pregnant and breastfeeding women should consult a doctor or healthcare professional before starting antioxidant supplements.
