Macushield capsules of Douglas Laboratories

Provide a multi-vitamin and mineral formulation with

Several key nutrients, including vitamin A, betacarotene,

Bilberry extract, L-taurine, L-glutathione,

And zinc, that are important in maintaining normal eye


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 photoreceptor activity.

Macushield capsules may be a useful dietary

Supplement for those who wish to increase their

Intake of nutrients that may improve the functioning

Of their vision.
