Zinplex is a South African supplement range built around zinc, commonly taken for skin — particularly acne — and for immune support. It does not appear in the Medicine Price Registry, which is normal for a supplement, so check your own pack for what it actually contains.
What is Zinplex?
We cannot confirm what your pack of Zinplex contains, and this page will not guess at the formulation.
A search of the South African Medicine Price Registry returns no product under this name. That is unremarkable here: supplements and complementary medicines follow a different regulatory route and generally do not appear in a medicine price registry. Absence there does not mean a product is illegitimate.
What the name indicates is zinc — zin — in a combination product, and Zinplex is marketed in South Africa as a zinc-based range including tablets, syrups and topical products, often aimed at skin and immunity. Read your own label for the zinc form and amount, and for anything else included.
What zinc actually does is well established, and worth knowing regardless of the brand:
- Immune function. Zinc is required by a large number of immune cells and enzymes; deficiency measurably impairs immunity.
- Wound healing and skin integrity.
- Protein and DNA synthesis, and cell division — which is why it matters for growth and for tissues that turn over quickly, such as skin.
- Taste and smell.
- Testosterone and reproductive function.
Zinc deficiency causes poor wound healing, hair loss, diarrhoea, taste disturbance, skin rashes around the mouth and eyes, frequent infections, and impaired growth in children.
On acne specifically, since that is a common reason people reach for it: zinc has genuine but modest evidence. Some trials show improvement in inflammatory acne, though generally less than standard treatments such as topical retinoids, benzoyl peroxide or antibiotics. It is a reasonable adjunct, not a replacement for treatment of moderate or severe acne, which can scar permanently if left.
What is Zinplex commonly used for?
- Acne and problem skin — the most common reason in South Africa.
- Immune support, particularly through winter or during recurrent infections.
- Wound healing, after injury or surgery.
- Zinc deficiency, from poor diet, malabsorption or increased losses.
- Hair and nail health.
- Colds, where zinc lozenges started within 24 hours may modestly shorten duration — though zinc taken as a tablet or syrup, rather than a lozenge dissolved in the mouth, does not show the same effect.
- Children’s growth and appetite, where deficiency is present.
- Diarrhoea in children, where the World Health Organization recommends zinc alongside oral rehydration.
A supplement corrects a shortfall; it does not add benefit beyond that. Zinc is present in meat, shellfish, dairy, legumes, nuts and wholegrains. Deficiency is more likely in vegetarians and vegans — plant sources contain phytates that reduce absorption — and in people with gut conditions, alcohol dependence or poor diets.
Who commonly looks for Zinplex and why
- Teenagers and young adults with acne, or their parents — the largest group.
- People with recurrent colds or infections.
- People with poor wound healing, or recovering from surgery.
- Vegetarians and vegans, at higher risk of deficiency.
- People with hair thinning or brittle nails.
- People with taste or smell changes.
- Parents of children who are small for their age, or have poor appetite.
- People with gut conditions affecting absorption.
- People who were recommended it by a pharmacist or friend and want to know what it does.
What to check on the label before taking Zinplex
- The amount of elemental zinc per dose. This is the figure that matters — “zinc gluconate 50 mg” is not 50 mg of zinc. Reputable labels state elemental content.
- The zinc form. Gluconate, citrate, picolinate and bisglycinate are better absorbed than oxide or sulfate, and gentler on the stomach.
- What else is in it. Zinc products often include vitamin C, vitamin A, selenium or herbal extracts — and vitamin A in particular matters if you are pregnant or already take a multivitamin.
- Whether you already take a multivitamin containing zinc. Totals add up quietly.
- Whether it is a lozenge, if you are taking it for a cold — the format determines whether it works for that purpose.
- The recommended amount and frequency.
- The expiry date and storage.
Adults need only about 8 to 11 mg of elemental zinc daily. Supplements often provide considerably more, which is fine short-term but relevant to the cautions below.
Safety, interactions and when to seek professional advice
Zinc is generally well tolerated at sensible doses. The most common effects are nausea, stomach upset and a metallic taste — much reduced by taking it with food.
The main risk is prolonged high intake, and it has a specific and often-missed consequence:
Zinc and copper compete for the same absorption pathway. Sustained high zinc intake — generally above about 40 mg of elemental zinc daily over months — causes copper deficiency, which produces anaemia that does not respond to iron, low white cell counts, and in some cases irreversible neurological damage including numbness, weakness and unsteadiness. This is a genuine and under-recognised problem in people taking high-dose zinc long term for skin or immunity.
Other points:
- Very high single doses cause vomiting, cramps and diarrhoea.
- Zinc interferes with the absorption of several medicines — separate it by at least two hours from:
- Antibiotics, particularly tetracyclines such as doxycycline and quinolones such as ciprofloxacin. This can cause treatment to fail.
- Iron and calcium supplements, which compete with it.
- Penicillamine and some thyroid medicines.
- Dolutegravir and other HIV medicines, where binding reduces absorption.
Speak to a doctor or pharmacist before taking it if you:
- Take any of the medicines above.
- Have kidney disease.
- Are pregnant or breastfeeding — check the vitamin A content of any combination product.
- Are giving it to a child.
- Already take a multivitamin containing zinc.
- Have anaemia, or are being investigated for it.
- Plan to take it long term at high doses.
See a doctor rather than self-treating if you have:
- Moderate or severe acne, particularly if it is scarring or affecting your confidence. Effective treatments exist, and scarring is preventable but not reversible.
- Persistent poor wound healing.
- Hair loss, which can indicate thyroid disease, iron deficiency or other treatable conditions.
- Recurrent or unusual infections, which warrant assessment.
- Persistent diarrhoea or unintended weight loss.
- Numbness, tingling or unsteadiness — particularly if you have been taking high-dose zinc, given the copper issue above.
- Taste or smell loss that persists.

Frequently asked questions
What are Zinplex tablets used for? It is a zinc-based supplement range, commonly taken for acne and problem skin, and for immune support. Check your pack for the exact formulation.
Why is it not in the medicine registry? Supplements and complementary medicines follow a different regulatory route and generally do not appear there. That does not make them illegitimate.
Does zinc help acne? There is genuine but modest evidence for inflammatory acne — generally less effect than standard treatments. It is a reasonable adjunct, not a replacement.
Does zinc prevent colds? Zinc lozenges started within 24 hours may modestly shorten a cold. Tablets and syrups do not show the same effect, and zinc does not reliably prevent colds.
How much zinc do I need? Adults need about 8 to 11 mg of elemental zinc daily. Check the elemental figure, not the weight of the zinc salt.
Can I take too much? Yes. Sustained intake above about 40 mg daily causes copper deficiency, which can produce anaemia and irreversible nerve damage.
Can I take it with antibiotics? Not at the same time. Zinc binds several antibiotics and can cause treatment to fail — separate them by at least two hours.
Should I take it with food? Yes, generally. It reduces the nausea and metallic taste that zinc commonly causes on an empty stomach.
