Antioxidant sources can be natural or man-made. It is thought that certain plant based foods are rich in antioxidants. Antioxidants based on plants are some kind of phytonutrient, or nutrient based on plants. The body also produces certain antioxidants which are known as endogenous antioxidants. Antioxidants from outside the body are called exogenous. Free radicals are cell-produced waste substances, as the body processes food and reacts to the environment. If the body cannot effectively absorb and eliminate free radicals, the effect will be oxidative stress. This can damage the functioning of cells and the body. The reactive oxygen species (ROS) are also known as free radicals. Factors that enhance the body's production of free radicals may be internal, such as inflammation, or external, such as pollution, UV exposure, and cigarette smoke. Antioxidants are said to help our bodies neutralize free radicals, and this is believed to boost overall health.

Antioxidants, known as oxidative stress, can protect against the cell damage that free radicals cause. However, overall there is a lack of evidence that a higher intake of specific antioxidants may reduce the risk of illness. Results tended to show no benefit or a detrimental effect in most cases, or were conflicting.
