Description: Macushield 180c is available by Douglas Laboratories.
A Dietary Supplement
capsules of Douglas Laboratories® provide a multi-vitamin and mineral
formulation with several key nutrients, including Vitamin A,
Beta-Carotene, Bilberry Extract, L-Taurine, L-Glutathione, and Zinc
that are important in maintaining normal eye function.
Macushield™ capsules may be a useful
dietary supplement for those who wish to increase their intake of
nutrients that may support the healthy functioning of their vision.
More than any other tissue in the body,
the ocular lens and retina are continually exposed to oxygen and
intense light radiation. Both light and oxygen can create free radicals
that play havoc with membrane lipids of visual cells. Experts believe
that the uncontrolled generation of free radicals in the eyes can
ultimately lead to macular degeneration and cataracts. Therefore,
ocular tissue relies on a strong antioxidant defense system to protect
them from free radical damage.
Extracts of bilberry and Ginkgo
biloba, green tea, rutin, quercetin, and hesperidin are a rich source
of flavonoids that provide potent antioxidant defense in retinal visual
cells and help maintain healthy vascularization in ocular tissue.
Glutathione and selenium are essential components for healthy activity
of the antioxidant enzyme glutathione peroxidase which is abundant in
healthy eyes. Glutathione peroxidase levels, however, decline with
advancing age, and an adequate dietary supply of glutathione, its
precursor N-acetyl-L-cysteine, and selenium may help maintain healthy
levels of this important enzyme.
Beta-carotene serves at least
two purposes for the eyes. It is a valuable precursor for vitamin A
which functions in the retinal cells as a light receptor. Betacarotene,
as well as other carotenoids in Macushield™, such as lutein and
lycopene, are also important antioxidants in the lens and retina. Zinc
is not only essential for normal visual signal transduction in the
retina, but also is part of many of the enzymes involved in vitamin A
dependent light reactions in retinal cells.
Moreover, Zinc, as
well as Copper and Manganese, are essential cofactors of superoxide
dismutase, an antioxidant enzyme that removes potentially dangerous
superoxide radicals in the visual cells, the lens, and other tissues.
Taurine, the most abundant free amino acid in ocular tissue, is thought
to help stabilize neural membranes in retinal cells and modulate
