What is zinc?

Zinc is an essential trace mineral involved in immune function, wound healing, taste and smell, skin health and countless enzyme reactions. Your body has no large store of it, so a steady dietary supply matters.

Why it matters

Zinc supports immunity and repair, and a shortfall can show up as slower healing, changes in taste or more frequent infections. It is a useful nutrient marker, particularly for people with limited dietary variety or higher needs.

What your results can mean

Lower than optimal

A low zinc can relate to diet, gut absorption or increased demand, and can affect immunity and healing. It is generally addressable with dietary change or supplementation under guidance.

Within the healthy range

A zinc in range supports immune and enzyme function. As with other minerals, blood levels are one part of the picture and are read alongside your symptoms.

Reference ranges in Australia

Zinc is reported in micromoles per litre (µmol/L), with laboratory-specific reference ranges, and can be affected by recent meals and the time of the draw. Read your result against your own report.

Test your zinc with Precursor

Zinc is best read alongside your other nutrient markers. At Precursor it is measured as part of Full Advanced Bloods, a single clinician-reviewed blood draw covering your vitamins, minerals and other markers together, giving you and your clinician a broad baseline to understand and track.
