Description: Beta Carotene Dry Capsules 100c is available by Douglas Laboratories.
A Dietary Supplement
capsules, as provided by Douglas Laboratories, contain pure,
synthetically-derived beta-carotene. Each capsule provides 25,000 I.U.
Vitamin A activity.
Beta-carotene may be a useful dietary supplement for those who wish to increase their daily beta-carotene intake.
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 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.
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.
molecule of beta-carotene can quench about a thousand molecules of
singlet oxygen. Numerous studies have demonstrated the importance of
beta-carotene for normal immune function. The immune benefits of
beta-carotene are due to its Vitamin A precursor role and its
antioxidant functions. Beta-carotene is present in selected fruits and
vegetables such as carrots, sweet potatoes, and green leafy vegetables.
The U.S. Department of Agriculture and the National Cancer Institute
recommend an intake of 5 mg (8,335 I.U.) or more of beta-carotene.
Unfortunately, most diets provide only 1-2 mg (1,667 - 3,334 I.U.) per
