Assessing zinc status can be difficult, as most of the body’s zinc stores are in the bones. Hair analysis, levels in sweat, blood serum or white blood cells all require considerable (and costly) laboratory work.
Zinc Taste Test provides a quick and reliable clinical test for the assessment of zinc status.
Studies have demonstrated this test to be reliable and reproducible. It provides patients with a simple and inexpensive screening method for determining the need for zinc. By using the oral Zinc Taste Test to determine the need for zinc, and retesting after 30 days of supplementation, one can not only determine zinc requirements, but also monitor the patient to be sure they are properly absorbing their zinc.
Numerous research studies have found that sub-optimal levels of zinc are very common at all ages, especially in the elderly. An Australian study found that 85% of women and 65% of men do not receive the RDA for zinc in their diets.
Responses to tasting 10 mL of the solution are:
Category 1 – No specific taste or other sensation is noticed, even after the solution has been kept in the mouth for about ten seconds.
Category 2 – No immediate taste is noted, but after a few seconds a slight taste variously described as dry-mineral, furry, or sweet develops.
Category 3 – A definite, though not strongly unpleasant taste is noted almost immediately and tends to intensify with time.
Category 4 – A strong and unpleasant taste is noted immediately. Category 1 is the poorest zinc status, while category 4 is optimal. If the taste response is in category 1 or 2, a zinc deficiency is likely. Metagenics Zinc Drink can then be used for direct supplementation until category 3 or 4 taste is noted.
