As an essential mineral for life, zinc plays a key role in many important physiological functions as well as providing important immune support.
Liquid Zinc Assay contains liquid zinc as zinc sulfate. This product is made using purified water - not filtered or tap water which may contain impurities that could potentially distort a zinc taste test.
To use Liquid Zinc Assay as a supplement, take 1 teaspoon in water or juice daily or as directed by a health professional. To use as a zinc test: hold 1 teaspoon in the mouth for 15 seconds. If an immediate perception of taste occurs, the person may have an adequate zinc status. If a lack of taste or delay in taste perception occurs, it may indicate a zinc deficiency. Liquid Zinc Assay may be swallowed after testing. Our liquid zinc is made using 100% purified water, not filtered or tap water which may contain impurities.
