The different antioxidants are present at a wide range of concentrations in body fluids and tissues, with some such as glutathione or ubiquinone mostly present within cells, while others such as uric acid are more systemically distributed (see table below). Some antioxidants are only found in a few organisms, and can be pathogens or virulence ...
Isoflavone phytoestrogens - found primarily in soy, peanuts, and other members of the family Fabaceae; Resveratrol - found in the skins of dark-colored grapes, and concentrated in red wine. Pterostilbene - methoxylated analogue of resveratrol, abundant in Vaccinium berries
Lycopene is an antioxidant commonly found in tomatoes — it has been shown to prevent cell damage and provide myriad benefits to the body, including but not limited to helping improve sperm count.
Coenzyme Q 10 (CoQ 10 / ˌ k oʊ k j uː ˈ t ɛ n /), also known as ubiquinone, is a naturally occurring biochemical cofactor (coenzyme) and an antioxidant produced by the human body. [1] [2] [3] It can also be obtained from dietary sources, such as meat, fish, seed oils, vegetables, and dietary supplements.
But similar methods are not available for other tissues and for the extrathyroidal organs. Many researchers reported different numbers of 10–50 mg of the total iodine content in human body". [4] [5] Selenium also plays a very important role in the production of glutathione, the body's most powerful antioxidant.
Antioxidants are helpful in reducing and preventing damage from free radical reactions because of their ability to donate electrons which neutralize the radical without forming another. Vitamin C, for example, can lose an electron to a free radical and remain stable itself by passing its unstable electron around the antioxidant molecule.
Vitamin A acts as a regulator of cell and tissue growth and differentiation. Vitamin D provides a hormone-like function, regulating mineral metabolism for bones and other organs. The B complex vitamins function as enzyme cofactors (coenzymes) or the precursors for them. Vitamins C and E function as antioxidants. [7]
Another small study on people without diabetes who were overweight or had obesity found that those taking metformin lost between 5.6 and 6.5 percent of their body weight. In contrast, the control ...
