Antioxidant status refers to the body's ability to neutralise harmful substances known as free radicals, which can damage cells and contribute to chronic diseases and ageing. Antioxidants, both from dietary sources and produced within the body, work as a defence system to protect cells from oxidative stress - a process that can occur from exposure to pollutants, poor diet, high stress, and even intense physical activity. Maintaining a balanced antioxidant status is essential for cellular health, as it helps reduce inflammation, supports immune function, and preserves tissue integrity. Key factors influencing antioxidant status include nutrient intake (such as vitamins C and E, selenium, and zinc), lifestyle choices like diet and smoking, and managing stress levels. A healthy antioxidant balance can be achieved through a nutrient-rich diet, regular physical activity, and reducing exposure to environmental toxins.
