Overview
Zinc in a methionine sulfate complex is what this Source Naturals tablet delivers. It is an uncoated, unflavored tablet for adults, sold in a small bottle, with a long list of things it leaves out.
The reason to choose it is the clean free-from profile: no artificial colors or flavors, no preservatives, no yeast, and no common allergens such as dairy, egg, soy or wheat. The limitation is that the zinc amount per tablet is not listed in the data, so check the label before you plan a daily dose.
Who it's for
Adults who want zinc on its own and need a tablet free of dairy, egg, soy, wheat, yeast and artificial additives. Anyone after a broad vitamin blend, or who needs the dose confirmed up front, should look elsewhere.
Pros and cons
- Zinc methionine sulfate complex
- Free of common allergens
- No artificial colors or flavors
- Vegetarian and gluten free
- Zinc amount per tablet not listed
- Single mineral only
- Uncoated tablet may be harder to swallow
Performance notes
A zinc methionine complex binds the mineral to an amino acid, which is the idea behind the OptiZinc name. How much zinc you take depends on the tablet strength, which the page does not state. The tablet is uncoated, so it has no film to ease swallowing.
