It isn't known if this is effective in preventing ARMD and caution must be exercised when taking large doses. Too much of anything, even if it is good, has the ability to cause harm. Zinc is another element found throughout our bodies and is most heavily concentrated in the eye, especially in the retina and macula. It acts as a catalyst in over a 100 enzymatic and chemical reactions which are vital to the retina. Consequently, researchers have been experimenting with zinc supplements to discourage ARMD's progression.
Studies concerning the effectiveness of vitamin and zinc therapies are currently inconclusive.
Even if research proves these therapies to be effective in hindering ARMD, caution should be exercised in taking therapeutic doses. However, there are several multiple vitamins commercially available for ARMD patients.
