1) What is zinc (and what does it do)?

Zinc is an essential mineral — meaning your body needs it, but you can’t make it yourself. You have to get it from food (and sometimes supplements).

It’s involved in lots of everyday “maintenance” work inside the body, including:

• Normal immune function (one reason zinc shows up in so many winter routines)
• Skin support and wound healing (your body uses zinc for repair processes)
• Normal growth and development (especially important in childhood and during pregnancy)
• Taste and smell (zinc is linked with how well these senses work)

The main point: zinc isn’t a “quick fix” nutrient — it’s a “foundations” nutrient. If your foundations are solid, everything else tends to work better.

2) How much zinc do you need in the UK?

In the UK, the recommended daily amount is:

• Men (19+): 9.5mg per day
• Women (19+): 7mg per day

Most people can reach this through food — especially if they eat a mix of protein foods (like meat, fish, dairy, legumes) plus nuts/seeds.

What about upper limits?

With zinc, “just in case” high dosing is where people can get into trouble. In the UK, general guidance is to avoid taking more than 25mg of zinc per day from supplements unless a healthcare professional recommends it.

Why the caution? Higher zinc intakes can cause side effects like nausea and stomach upset — and if taken for weeks at higher doses, zinc can interfere with copper absorption (which can create new problems while you’re trying to solve another one).

3) Low zinc: who’s at higher risk (and what can it look like)?

True zinc deficiency isn’t something you want to self-diagnose from a blog — symptoms can overlap with many other issues. But it’s still useful to know when zinc intake can be lower than expected.

People who may want to pay closer attention

• People eating mostly plant-based diets (zinc is present in plant foods, but it can be less absorbable depending on the diet)
• People with gut issues that reduce absorption (or after certain surgeries)
• People who rarely eat high-zinc foods (for example: very low-protein diets)

What low zinc can look like (broadly)

Low zinc can affect many systems in the body. Depending on the person, it may be linked with things like changes in taste/smell or slower wound healing. But those signs can have many causes — so if something feels “off” and it’s persistent, it’s worth speaking to a clinician and considering basic tests rather than guessing.

Good news: if your diet is a bit inconsistent (very common), you can usually improve your zinc intake with a few smart food choices and a simple supplement routine — without mega-dosing.

4) Best food sources of zinc (UK-friendly)

Before thinking “supplement”, it helps to know where zinc naturally shows up in food. For many people, improving zinc intake is as simple as adding one or two reliable zinc foods a few times a week.

Higher-zinc foods (easy wins)

• Meat (beef, lamb, pork) and poultry
• Seafood (especially shellfish)
• Dairy (cheese, milk, yogurt)
• Eggs

Good zinc options if you eat mostly plant-based

Plant foods can contain zinc too, but absorption can be lower depending on the overall diet. That doesn’t mean plant-based diets can’t work — it just means you may need a bit more planning.

• Beans and lentils (great “foundation” food overall)
• Chickpeas and hummus
• Nuts and seeds (pumpkin seeds are a common go-to)
• Wholegrains (oats, wholemeal bread, brown rice)

Simple “zinc meals” you can repeat

• Breakfast: Greek yogurt + mixed seeds + fruit
• Lunch: chicken or tuna salad bowl + wholegrain carbs
• Dinner: chilli con carne / lentil chilli + rice + veg
• Snack: cheese + fruit, or hummus + wholegrain crackers

5) Zinc supplements: how to choose (and how to take it without feeling sick)

Zinc supplements can be useful when your diet is inconsistent, your intake is likely low, or you want a simple routine you can keep. The key is picking a sensible dose and taking it in a way that fits your day (and your stomach).

Step 1: Choose a sensible dose (avoid “more is better”)

Many zinc products look “strong” on the label. That doesn’t mean you need the strongest option. In general, it’s smart to stay within UK guidance and avoid high-dose zinc for long periods unless you’ve been advised by a clinician.

• If you already take a multivitamin: check how much zinc is in it before adding another zinc product.
• If your zinc product is close to the upper guidance: treat it as a targeted, time-limited routine (then review).
• If you’re unsure: a pharmacist can quickly sanity-check your stack.

Step 2: Don’t overthink the “type” of zinc

You’ll see different zinc forms (such as citrate, gluconate, picolinate, etc.). For most people, the bigger difference is: what dose you take, how consistently you take it, and whether it agrees with your stomach. If one type feels rough, switching form or taking it with food often solves the issue.

Best time to take zinc (for most people)

The “best” time is the time you’ll actually repeat. That said, zinc has a reputation for causing nausea when taken on an empty stomach — so most people do better taking it with a meal or a decent snack.

• If you’ve felt nausea before: take zinc with your main meal (not just a coffee or a small biscuit).
• If you already take supplements at lunch: lunch is a great anchor meal because you’re less likely to forget than at night.
• If evenings suit you better: dinner is fine — consistency beats the “perfect” timing.

How to avoid the common “zinc nausea” problem

• Take it with food (proper meal or solid snack).
• Avoid taking zinc on an empty stomach first thing if you’re sensitive.
• Start smaller (or take it every other day initially) and build up if needed.
• If nausea continues: try moving the timing or switching zinc form; if it’s still unpleasant, stop and reassess.

Spacing: what not to take at the exact same time

Zinc doesn’t have to be complicated — but there are a few “don’t pile everything into one minute” situations that are worth knowing. (Always follow the leaflet for any prescription medicine.)

• Antibiotics (important): zinc can reduce absorption of some antibiotics if taken together. If you’re on antibiotics, follow the medicine guidance and consider separating zinc by a few hours.
• Other minerals: some people prefer spacing zinc away from iron, calcium, or magnesium for comfort and to reduce “competition”. If your stomach feels fine taking them together, it’s not always an issue — but spacing can be a simple fix if you’re getting nausea.
• Fibre supplements: if you take Psyllium Husk + Probiotics, many people take fibre at a different time from minerals, simply to keep digestion comfortable. Always take fibre with water.

How long should you take zinc for?

If you’re taking zinc as a “support during a hectic season”, it’s sensible to treat it like a short programme: run it consistently for a few weeks, then review. If you’re tempted to take higher-dose zinc for months, that’s the moment to pause and check you’re not creating imbalance (especially with copper).

6) Common zinc mistakes (and easy fixes)

Zinc is simple — until it isn’t. The good news: most problems come from a few predictable habits. Fix the habit, and zinc usually becomes “easy”.

Mistake #1: Taking zinc on an empty stomach

This is the most common reason people quit zinc after a few days. If it makes you feel sick, anchor it to food (lunch or dinner).

Mistake #2: Accidental stacking (multivitamin + zinc + “beauty” formula)

People often forget zinc shows up in multiple products. Before stacking, do a 30-second label check: add up your daily zinc across everything. If you’re already close to the upper guidance, consider choosing one zinc source rather than three.

Mistake #3: Taking high-dose zinc for a long time

Higher zinc intakes aren’t automatically better. Long-term, high-dose routines can contribute to copper absorption issues. If you’re using zinc consistently for months, it’s smart to discuss it with a clinician (or keep the dose conservative).

Mistake #4: Taking zinc at the same time as certain antibiotics

If you’re on antibiotics, the medicine leaflet matters more than a blog. Zinc can reduce absorption of some antibiotics if taken together. If you want to keep zinc in your routine, separate timing and follow your pharmacist/GP’s advice.

Mistake #5: Expecting zinc to “fix” everything quickly

Zinc supports normal body processes — it doesn’t usually create a dramatic overnight change. A better approach: keep zinc as part of the foundations (sleep, food, hydration), then reassess after a few weeks.

7) FAQs (People Also Ask)

Quick, practical answers to the most common zinc questions. Keep in mind: this is general information, not medical advice. If you’re pregnant/breastfeeding, have a medical condition, or take prescription medicines, ask a pharmacist/GP before starting supplements.

How much zinc do I need per day in the UK?

UK guidance is 9.5mg/day for men and 7mg/day for women. Most people can reach this through a varied diet. If you take a supplement, avoid “mega dosing” as a default — high strength isn’t always better.

Is it safe to take zinc every day?

For many people, daily zinc is fine if the dose is sensible and you’re not stacking multiple zinc products. UK advice says do not take more than 25mg a day from zinc supplements unless a doctor advises it. If you’re taking zinc daily for months, keep the dose conservative and review whether you still need it.

What’s the best time to take zinc?

The best time is the time you’ll actually repeat. For most people, with lunch or dinner is ideal because it’s easier to remember and tends to be gentler on the stomach.

Why does zinc make me feel sick?

Zinc can cause nausea or an upset stomach, especially if you take it on an empty stomach. The simplest fix is to take it with a proper meal (not just coffee). If it still bothers you, reduce the amount (within label guidance), change timing, or stop and reassess.

Can I take zinc with vitamin C?

Many people pair them. The main thing is avoiding accidental stacking across multiple products. If you’re already using a multivitamin or a hair/skin formula that includes zinc, check totals before adding a separate zinc supplement.

Can I take zinc with magnesium, iron, or calcium?

Some people take minerals together with no issues, but others find it easier on digestion to space them out. If you feel nausea, try taking zinc at a different meal from other minerals and see if it improves.

Does zinc interfere with antibiotics?

Zinc can reduce absorption of some antibiotics (including tetracyclines) if taken at the same time. If you’re on antibiotics, follow the medicine leaflet and ask your pharmacist about spacing. A common approach is separating doses by a few hours.

Can too much zinc cause problems long-term?

Yes. Regular high-dose zinc (especially above sensible daily use for long periods) can contribute to issues like stomach upset and may interfere with copper absorption. If you’re using higher-strength zinc long-term, it’s worth a quick check with a clinician.

Should I take zinc if I think I’m deficient?

If you suspect deficiency, it’s better to speak to a clinician rather than guessing — symptoms can overlap with many other issues. A food-first approach plus a sensible supplement routine can be helpful, but persistent symptoms deserve proper assessment.

8) Who should check with a GP or pharmacist first?

If any of the points below apply, it’s smart to get personalised advice before starting zinc (or increasing the dose). A quick check can prevent interactions and avoids accidental overdoing it.

• Pregnant or breastfeeding (needs vary; get tailored advice)
• Taking antibiotics (zinc can reduce absorption of certain antibiotics if taken together)
• Taking prescription medicines regularly (your pharmacist can check interactions fast)
• Kidney disease or significant chronic health conditions
• Gut conditions or malabsorption (dose and form may matter more)
• Already taking multiple supplements (to avoid stacking zinc across products)
• Planning to take higher-strength zinc for months (long-term use is where imbalance risk rises)

9) Where Vita London products fit (optional, simple)

If you want zinc as part of a routine you can keep, here are a few straightforward options — without turning this into a sales pitch. Always check labels if you stack products.

• Everyday combo: Vitamin C & Zinc — a simple one-a-day option that suits many people’s “anchor meal” routine.
• Beauty-support formula (includes zinc): Hair, Skin & Nails. If you use this, you may not need an additional zinc product on top.
• General cover for busy weeks: A–Z Multivitamin. Useful if your diet is inconsistent — just avoid doubling nutrients with separate high-dose products.

10) Bottom line

Zinc is a “foundations” mineral: it supports normal everyday processes (including immune and skin function), but it’s not a magic switch. For most people, the best approach is simple: get zinc from food where you can, use a sensible supplement dose if needed, take it with a meal to avoid nausea, and avoid long-term high-dose routines unless you’ve been advised by a professional.
