Free radicals
Highly reactive and unstable oxygen molecules generated during normal body processes that can harm basic genetic material (DNA) as well as other cell structures and tissues.

Exposure to heat, radiation and environmental pollutants (including cigarette smoke), and drinking alcohol can also promote the formation of free radicals.

Free-radical damage can lead to heart disease, cancer, cataracts, arthritis, neurological diseases and other ailments. Antioxidants help minimize free-radical damage.
