Zinc taste tests are commonly used by complementary and alternative practitioners, pharmacies and in medical practices and research to determine zinc status and deficiency. However, despite this common use, evidence for the reliability and accuracy of this test for determining zinc status is lacking.
It is the position of the Holistic Performance Institute that unless further research can demonstrate accuracy and reliability of zinc taste testing, the use of this test in clinical practice should be avoided due to the potential to misdiagnose zinc deficiency and the risk of zinc overload.
