Antioxidants help to protect against free radical damage. We are exposed to these daily due to our environment (pollution, chemicals, cigarette smoke) and due to natural chemical processes in our own bodies. Free radicals cause damage to the cells of the body which can have negative effects on our health.
Studies show that people with low levels of antioxidants are more likely to develop Age-Related Macular Degeneration (AMD). This causes the reduction of vision in the centre of the eye (the macula) and is one of the leading cause of blindness and vision impairment in older people (>50 years).
