A Mineral That Travels With an Amino Acid
Zinc is a small atom with a big job list, but on its own it is a poor traveller. In a plant-rich meal, phytate from grains and beans can hold on to zinc and carry it straight through the gut. Animal nutritionists in the American Midwest knew this problem well, because livestock eat corn and soy every day. In the early 1970s a Minnesota chemist, Dr. Mahmoud Abdel-Monem, tried a different idea: instead of feeding zinc as a bare mineral salt, pair each zinc atom with one molecule of methionine, an essential amino acid the body already knows how to take in. His one-to-one zinc methionine complex was patented in 1976.1
The real test came on the farm feed itself. In a 1992 study, researchers fed young chicks three kinds of diets and compared zinc methionine with ordinary zinc sulfate. On a simple, low-fiber diet the two were close. On a typical corn and soybean diet, full of plant phytate, the zinc from zinc methionine was used about twice as well.2 The richer the plate in plants, the more the amino-acid partner seemed to matter.

Dr. Mahmoud Abdel-Monem of Zinpro Corporation, Minnesota, files and wins U.S. Patent 3,941,818, "1:1 Zinc methionine complexes," written for both animal and human nutrition.1
|
| 1992 |
A chick study in the Journal of Animal Science rates zinc methionine at 117% to 206% of zinc sulfate, depending on how much plant fiber and phytate is in the feed.2
|
| 1994 |
A second Zinpro patent, U.S. 5,278,329, covers complexes made with L-methionine only, the natural form found in food protein, instead of the mixed DL form.3
|
| Later |
InterHealth Nutraceuticals of Benicia, California, brings the L-form complex to people as L-OptiZinc®. The brand is now part of Lonza.4
|
| Today |
Every AlchePharma tablet carries 20 mg of zinc from L-OptiZinc®: one tablet, once a day, with a meal. |
What the Research Looked At
|
ANIMAL STUDY · 1992
Plant-rich diets
In chicks on a corn and soybean diet, zinc methionine was rated at 206% of zinc sulfate. On a low-fiber diet the gap was much smaller (117%).2
|
HUMAN DATA · MANUFACTURER
Absorbed and retained
The ingredient maker reports that, in people, L-OptiZinc® was absorbed better than zinc sulfate and zinc polyascorbate, and raised blood zinc more than zinc oxide over 12 hours.4†

WHY ZINC MATTERS
An everyday essential
Zinc helps hundreds of enzymes work, supports normal immune function and healthy skin, and is part of copper-zinc superoxide dismutase, one of the body's own antioxidant enzymes.5†

The Extra Care in Every Tablet
The patented form, not the cheapest one. Many zinc products use a plain mineral salt such as zinc oxide, because it is inexpensive. We chose L-OptiZinc®, the patented complex made with L-methionine only, so the zinc in your tablet arrives already paired with an amino acid.
A sensible amount. 20 mg in one tablet covers the daily value with room to spare, without the 50 mg megadoses some brands sell. One tablet a day keeps it simple.
A short, clean label. No sugar, salt, dairy, yeast, wheat, gluten, corn, soy, preservatives, artificial colors or flavors, and a 250-tablet size that lasts more than eight months.
| ✅ GLUTEN-FREE |
✅ NO SUGAR · SALT · DAIRY |

✅ NO PRESERVATIVES OR ARTIFICIAL COLORS |
SUGGESTED USE
Serving size: 1 tablet
As a dietary supplement, adults take one (1) tablet daily with meals, or as directed by a health care professional. Store in a cool, dry place and away from direct light.

⚠️ BEFORE YOU USE
Talk with your healthcare provider before use if you are pregnant or nursing, take any medication, or have a medical condition. The upper limit for adults is 40 mg of zinc a day from all sources, so count any other zinc you take, such as a multivitamin or lozenges.5 Keep out of reach of children.
