Why supplement?
Picolinate chelate
Picolinic acid is a tryptophan metabolite. Bound to zinc, a common claim is that it uses organic-acid channels. Some absorption studies beat zinc oxide, but that does not guarantee higher blood zinc for everyone. Still read milligrams of elemental zinc.
Immune and skin nutrition
The physiology is still zinc itself: immune enzymes, wound repair, and taste. The chelate ligand is not another vitamin.
How to take it
Check the elemental zinc on the label first.
How oftenUse according to daily need; long-term high doses should be medically monitored.
