Zinc is one of the most important everyday minerals, and a popular supplement for South Africans focused on immunity and skin. This guide explains the forms and how to choose. It is general information, not medical advice.
What zinc does
Zinc contributes to the normal function of the immune system, to healthy skin, hair and nails, and to normal cognitive function and fertility. The body doesn’t store zinc well, so a steady intake matters — and many diets fall a little short.
The main forms
- Zinc picolinate — a well-absorbed chelated form, a popular all-rounder.
- Zinc glycinate (bisglycinate) — gentle on the stomach and highly bioavailable.
- Zinc gluconate — widely available and affordable, common in immune products.
- Zinc complex — often paired with vitamin C or copper for balance.
How to choose
- Absorption: picolinate and glycinate are favoured chelated forms.
- Tolerance: take zinc with food if it upsets your stomach.
- Balance: long-term high-dose zinc is often paired with a little copper.
