Zinc is an essential mineral in our body that plays a key role in physiological function and immune support.  Liquid Zinc Assay contains zinc in the form of zinc sulfate.  This product can be utilized as a zinc supplement for individuals who have a zinc deficiency.  In addition, because Liquid Zinc Assay is made using purified water (not filtered or tap water, which can contain impurities that could distort a zinc taste test) it can be used for a zinc taste test.

As a supplement:  Take 1 teaspoon (5 mL) in water or juice‚ 2 times daily or as recommended by your healthcare provider.
