Oxidative stress is the damage made through the oxidative process. The damage can occur at a molecular, cellular or organ level or can affect the whole organism. Most reactive oxygen species are created as a by-product of normal and essential metabolic reactions, such as energy generation from mitochondria or the detoxification reactions involving the liver cytochrome P-450 exzyme system. This damage is associated with increased risk of disease and can affect the body at a molecular, tissue or organ level or can impact the entire organism. Reactive oxygen species are often referred to as free radicals or peroxides.

Causes of Oxidative Stress

Increased Oxidative Stress and Reactive Oxygen Species is a result of:

  • Endogenous sources
  • normal and essential metabolic reactions, such as energy generation from mitochondria
  • detoxification reactions involving the liver cytochrome P-450 enzyme system.
  • Exogenous sources:

Impact of Oxidative Stress

Oxidative stress has been implicated in many chronic and inflammatory diseases such as:[1]
