Douglas Labs Beta-Carotene
Beta-carotene may be a useful dietary supplement for those who wish to increase their daily beta-carotene intake.
What it is best for:
Beta-carotene is an important antioxidant nutrient that protects healthy cells from oxidative and free radical damage. Free radicals are unstable chemicals formed in the body during metabolism and from exposure to environmental sources such as pollution and cigarette smoke. Free radicals are necessary for energy metabolism and immune function, but when an excessive number of free radicals are formed, they can attack healthy cells, especially their membrane lipids and proteins. This, in turn, is thought to contribute to a number of degenerative diseases.
Beta-carotene is a safe precursor of vitamin A. Human intestinal enzymes convert dietary betacarotene into active vitamin A. The extent of this conversion appears to be based on the need for vitamin A since even very large amounts of betacarotene do not increase plasma or liver vitamin A levels above normal. One milligram of beta-carotene provides 1,667 I.U. of vitamin A activity. Betacarotene not converted to vitamin A is absorbed intact and has other functions in the body.
Beta-carotene efficiently quenches a chemically reactive species of oxygen called singlet oxygen. Singlet oxygen participates in oxidative reactions which can impair or destroy important cellular components, such as membranes, nucleic acids (DNA), and enzymes. In addition, singlet oxygen reactions can generate free radicals which lead to further damage. Beta-carotene's long, conjugated molecule can absorb the energy of singlet oxygen and release it safely as heat. In the process, singlet oxygen is converted to less dangerous, regular oxygen.
