OptiZinc and higher potency L-OptiZinc are unique, patented forms of methionine-bound zinc, an essential trace mineral required for numerous vital cell functions, including growth and development, reproduction, digestion, and for proper brain, nerve, vision and immune function. As an antioxidant (similar to vitamins E, C, and beta-carotene), OptiZinc and L-OptiZinc neutralize harmful free radicals, which may cause cell death and damage in the body.*

Zinc is an essential trace mineral involved in numerous enzyme systems the body needs to keep healthy and fit. OptiZinc and L-OptiZinc are patented 1:1 complexes of zinc and methionine, the amino acid best absorbed by the body. Studies show that OptiZinc and L-OptiZinc are absorbed better, retained longer and are more effective than other zinc supplements tested.

Research shows that a high-fiber meal can inhibit zinc absorption to under 3% of the amount consumed. A 1992 study showed that OptiZinc actually resists dietary fiber and phytate, and increases zinc absorption better than ordinary zinc supplements tested. In addition, unlike other zinc supplements, OptiZinc will not adversely affect copper absorption.

OptiZinc and L-OptiZinc are the only premium zinc supplements FDA-approved safe for human nutrition. Some zinc binding ligands, such as picolinic acid, have been shown to remove iron from cells and cause anemia, or increase lead absorption. OptiZinc and L-OptiZinc will not remove iron from cells or cause anemia. In fact, a 1991 study showed that a combination of zinc and methionine actually inhibits lead absorption and reduces lead levels in the blood.

OptiZinc is InterHealth's original methionine-bound zinc ingredient introduced in 1991. Standardized to 20% zinc, regular OptiZinc consists of zinc bound to the "DL" form of methionine (written as dl-methionine). L-OptiZinc, also standardized to 20% zinc, consists of zinc bound to the natural and more bioavailable "L" form of methionine (written as l-methionine). Studies show that both forms are highly bioavailable and potent antioxidants, but that L-OptiZinc is the most potent form of all.

The recommended adult daily dosage is 15 milligrams (elemental zinc as OptiZinc or L-OptiZinc) for both men and women; 18 milligrams for pregnant women; 7-8 milligrams for children 12 and under, taken with a meal. For additional information on dosing, follow manufacturer's recommended use printed on the label and/or talk to your healthcare professional.

High doses of zinc have been known to interfere with copper absorption and, when taken on an empty stomach, have been known to cause stomach upset. OptiZinc and L-OptiZinc do not interfere with copper absorption.

OptiZinc and L-OptiZinc are nutritional ingredients available in a wide variety of dietary supplements and nutraceutical food and beverage products. Most products can be found at your local health food store; otherwise you can order directly from the manufacturer. Look for the OptiZinc or L-OptiZinc logo on the label to be sure you're getting genuine bioavailable OptiZinc. Click to search for finished products that contain L-OptiZinc®: Search for Products
