antioxidants, plural;
  1. A substance that inhibits oxidation, esp. one used to counteract the deterioration of stored food products

  2. A substance such as vitamin C or E that removes potentially damaging oxidizing agents in a living organism

  1. substance that inhibits oxidation or inhibits reactions promoted by oxygen or peroxides
  2. An antioxidant is a molecule capable of inhibiting the oxidation of other molecules. Oxidation is a chemical reaction that transfers electrons from a substance to an oxidizing agent. Oxidation reactions can produce free radicals. ...
  3. Any substance that acts to slow or prevent the oxidation of another chemical; In nutrition, one of a group of vitamins that act against the effects of free radicals; Acting or having agents that act against oxidation
  4. (Antioxidants) They are powerful nutrients that prevent free radicals from causing damage to the skin cells. Free radicals are actually unstable oxygen molecules that take away electrons from their surrounding molecules thus creating a chain reaction and damaging the skin. ...
  5. (Antioxidants) compounds that protect cells from the damage caused by oxidation (free radicals). Mechanism of specific antioxidants:Vitamin E- protects lipids from free-radical damage. Vitamin C- scavenges free radicals; regenerates vitamin E after it has been oxidized. ...
  6. (Antioxidants) Agents that inhibit or neutralize potentially harmful compounds known as free radicals. Free radicals are produced during metabolic activity. High levels of free radicals may eventually lead to impaired functioning and destruction of neurons and other bodily cells. ...
  7. (Antioxidants) Substances, including beta-carotene, vitamin C, and vitamin E that may be able to reduce tissue and cellular damage due to oxidation, the process of oxygen breaking down other substances. ...
  8. Antioxidants are agents that prevent molecules called free radicals from destroying nerves and other cells in the body.
  9. (Antioxidants) Known to prevent the damage done by free radicals by ending the free radical chain reaction before vital molecules are harmed. ...
  10. (Antioxidants) A vitamin or nutrient that may help prevent damage to the heart, arteries, and other tissues. Examples include vitamins C and E, and beta-carotene. (The American Heart Association believes data is currently inconclusive about the benefits of antioxidants on heart health.)
  11. (Antioxidants) Any substances that prevent or impede cell oxidation (destruction) by free radicals, etc.
  12. (antioxidants) Do I Need Antioxidants?
  13. (Antioxidants) substances such as Vitamins A, C and E and minerals such as copper, magnesium and zinc. Believed to destroy free radicals, which some scientists think may not only accelerate aging but also contribute to the formation of cancers and cataracts.
  14. (Antioxidants) Micronutrients that destroy or neutralize free radicals, molecules that have been implicated as one causative factor in the stimulation of abnormal cellular reproduction (cancer) and cellular destruction (aging).
  15. (antioxidants) compounds that protect against cell damage inflicted by molecules, called oxygen-free radicals, which are a major cause of disease and aging.
  16. (Anti-oxidants) prolong the induction period of a base oil in the presence of oxidizing conditions and catalyst metals at elevated  temperatures. ...
  17. (Antioxidants) These substances prevent the formation of free radicals, which can cause the oxidative deterioration that causes premature aging of the skin. Natural antioxidants like vitamins A, C and E are often included in skin care products to help fight wrinkles and other signs of aging.
  18. (Antioxidants) Vitamins or substances which impede oxidation or spoilage promoted by oxygen or peroxide. Substances, such as Vitamin E and C, which prevent oxidation at the cellular level.
  19. (antioxidants) These substances, which have received much publicity in recent years as potential life-extenders, prevent the too-rapid oxidation of nutrients, and counter the destructive effects of free radicals (chemically reactive molecules) in the body. ...
  20. (Antioxidants) When the body produces oxygen, it also produces free-radicals which can cause damage to blood cells. Antioxidants are nutrients contained in food, which prevent and repair some of the damage caused by free radicals. ...
  21. Antioxidants are substances found in certain foods that can prevent cancer-causing substances, such as free radicals, from harming our bodies.  For example, Vitamin C is an antioxidant.
  22. (Antioxidants) A group of vitamins, minerals, and enzymes called antioxidants that help protect our body from the formation of free radicals. ...
  23. (Antioxidants) these work by fighting the free radicals that cause damage to our skin. They help neutralize the damage, they are often found in anti aging skincare products
  24. (Antioxidants) Vitamins A, C and E, along with various minerals, which are useful to protect the body from "free radicals". Free radicals are unstable cells, which react with each, naturally created in the body, and also caused by factors such as smoking and radiation
  25. (Antioxidants) Chemical compounds or substances that are added to foams to improve their resistance to oxidation. An examples of oxidation in polyurethane foams is a gradual shift of color to yellow.
