Zinc Serum Zinc
A mineral your immune system, skin and sense of taste depend on.
Also printed asZn
What it measures
A mineral used by immune cells, skin, taste buds and testosterone production.
A shortfall shows up as slow wound healing, frequent infections and a dulled sense of taste.
Why it matters for how long you stay well
Diets built mainly on polished rice and wheat run short of it, and the phytate in whole grains and dal blocks some of what is there, so intake and absorption both matter.
How it shows up in daily life
Running low can dull your sense of taste, slow wound healing, thin your hair and leave you catching more infections.
High and low readings
When it reads high
Usually supplements.
When it reads low
Common on vegetarian diets, where phytates block absorption.
What moves it
Daily life
- meat, seafood, nuts, seeds and dairy
- phytate in grains and dal, which blocks absorption
- soaking and fermenting, which frees more of it
- alcohol
