How does Zinc work?
Zinc is needed by many enzymes and for making new cells, which is why it matters for wound healing. Very high intakes reduce how much copper the body absorbs.
How to take Zinc
Follow the label or your doctor's advice. UK guidance (NHS) says adults need about 9.5 mg (men) and 7 mg (women) a day, which a varied diet usually provides.
Side effects of Zinc
Zinc at label amounts is usually well tolerated. Taking too much for a long time can cause problems.
Uncommon or mild
- Nausea or an upset stomach, more likely on an empty stomach
Rare but serious: get medical help
- Swelling of the face, lips or throat, or difficulty breathing (an allergic reaction). Get medical help immediately
- Signs of anaemia, such as unusual tiredness or paleness, after long-term high-dose use
Who should be careful
Zinc supplements are best kept to the label amount.
- The NHS says not to take more than 25 mg of zinc supplements a day unless a doctor advises it
- High doses over time reduce copper absorption, which can lead to anaemia and weaker bones
- Check the zinc content of every supplement you take, as many multivitamins also contain it
If someone takes too much
A single extra tablet is unlikely to cause serious problems, but much larger amounts can cause vomiting and stomach pain. If someone has taken a large amount, ask a doctor or pharmacist, or call 112 or go to the nearest hospital if they are unwell.

Common questions
What does zinc do in the body?
It helps make new cells and enzymes, process carbohydrate, fat and protein, and heal wounds. Most people get enough from food. A supplement is only needed where the diet falls short or a doctor advises it.
How much zinc is too much?
The NHS advises not taking more than 25 mg of zinc supplements a day unless a doctor says so. Too much zinc for a long time lowers copper absorption, which can lead to anaemia and weaker bones. Check the pack and any other supplements you take.
