Best multivitamin supplements

Our independent multivitamin reviews reveal the best supplements to buy, who needs them and what to look out for.

We analysed 30 popular multivitamins that are widely available on the high street and online, including tablets, capsules, gummies and sprays.

Each has been rated on the quality and quantity of nutrients it contains, based on the latest available evidence. The products that scored well in our analysis were then lab-tested to confirm they contain what they claim to.

Our thorough, independent research means you can be confident in our recommendations when choosing a supplement. We've found that the most expensive multivitamins aren't necessarily always the best, and some budget options are brilliant value.

Why you can trust our multivitamin reviews

At Which? our reviews are completely independent and unbiased. We buy everything we test, looking at a range of prices and types to accommodate different budgets and needs.

Every food supplement we review is overseen by me, Shefalee Loth – Which?'s lead health and wellbeing researcher and a public health nutritionist. 

I've been scrutinising supplements for Which? for more than 10 years. Along with consultant dietitian Sophie Medlin, I've spent many hours reviewing the available evidence on multivitamins to determine the optimal dosages, and assessing popular products against this rigorous evidence framework.

How we assessed multivitamin supplements 

To find the best multivitamin and mineral supplements we selected a range of popular products sold in-store and online, including big brand and cheaper own-brand multivitamins from pharmacies, health stores and supermarkets.

Our in-house nutritionist and principal food and health research expert Shefalee Loth, along with registered dietitian Sophie Medlin, analysed the ingredients contained in each product, assessing them against set criteria for what multivitamins should ideally contain. 

Our assessment considered three key factors:

• Bioavailability – how easily absorbed a particular form of a nutrient is. Some are more readily absorbed by the body than others, and this may impact how much you actually benefit from them.
• Dose – our experts checked whether the supplement contained the full range of 23 essential nutrients you'd expect. They also looked at whether the dose of each nutrient is at the appropriate level, whether it's enough to prevent deficiency, or whether it's higher than is considered safe when taken regularly.
• Additives – our experts reviewed what else is in the supplement and whether it's necessary. None of the additives used are considered harmful, but some, such as PVA and talc, aren't things that some people would knowingly choose to ingest. In addition, if a product contains lots of bulking agents, additives or fillers, there are potentially fewer of the nutrients or active ingredients than you want. Additives can give an idea of the overall quality of the product, but we found the cheapest products aren't always the worst offenders.

Top-scoring products that are eligible to be Best Buys and Great Values are tested in an independent lab to spot-check that what they contain matches what's on the label, so we can be fully confident in our recommendations.

To qualify as a Best Buy, a multivitamin has to:

• Contain all 23 key nutrients identified by Which? experts as essential for a multivitamin, and 
• At least 10mcg vitamin D.

A Great Value supplement is a high-scoring product that costs less than 20% of the average cost of products in our test. 

What makes a good multivitamin?

Analysing multivitamins was a complex and time-consuming project, but we're confident in our Best Buy and Great Value recommendations. These are multivitamins we're happy you can pick off the shelf without scrutinising the label to check it covers everything you'd expect.

A multivitamin can't make up for a poor diet, but it can help fill in nutrient gaps.  A good multivitamin is one that contains a wide range of key vitamins and minerals in appropriate doses so that it works for most people.

Do you need to take multivitamins?

Most people don't need multivitamins, and it's important to remember that supplements aren't a substitute for a healthy, varied and balanced diet. For instance, a supplement can't provide fibre, polyphenols or other beneficial compounds you get from food. 

But, taking a multivitamin might be beneficial for certain people. For example, if you have an inconsistent, restricted or limited diet, you might be missing certain nutrients. This might be due to an allergy or intolerance, or irregular work patterns that make it hard to eat balanced meals. 

Older people may benefit too, as the ability to absorb nutrients from food decreases with age. A multivitamin may also help those with malabsorption issues (such as people with Coeliac or Crohn's disease). Some medications affect nutrient absorption, as do certain types of surgery on your gastrointestinal tract.

In these cases, and others, a multivitamin can offer you a 'safety net', although it's worth checking with your GP if you're on medication in case of possible interactions or contraindications. 

If you're concerned about a particular nutrient, check the label to make sure the supplement you're choosing contains it and has the correct dose. 

Dietitian Sophie Medlin, who is part of our expert supplement assessment panel, says: 'Multivitamins work in terms of raising your body's levels of the nutrients they contain (although this depends on bioavailability). But if you're expecting them to "fix" a poor diet and unhealthy lifestyle, then no, they don't work.'

Are multivitamins good for you?

Multivitamins can help top up missing nutrients in your diet, but they don't make you healthy or compensate for a poor diet.

There have been many research studies looking into the benefits of taking multivitamins. The findings are a mixed bag.

In June 2024, a study was published in the US where researchers analysed the data of almost 400,000 adults collected over 20 years to see whether multivitamin use affected their risk of death.

The study found that taking multivitamins didn't help people live longer. In fact, those who regularly took multivitamins had a marginally higher risk of dying during the study period.

However, a 2024 study published in The American Journal of Clinical Nutrition found evidence that multivitamins can help reduce cognitive decline. 

And another study published in Nature in March 2026 showed that adults aged around 70 who took a daily multivitamin for two years slowed biological ageing by 2-4 months.

Do doctors recommend multivitamins?

Doctors don't generally recommend multivitamins for healthy adults who eat a varied and balanced diet. 

The exceptions to this are:

• Women who are trying to conceive or who are pregnant. Folic acid and vitamin D are especially important during pregnancy, so you might choose to take individual supplements or take a multivitamin targeted at this group. Pregnant women shouldn't, however, take a general multivitamin because it can be risky to have too much of certain nutrients, such as vitamin A, while pregnant. See NHS advice, including whether you're eligible for free vitamins.
• Children aged six months to five years. Again, choose a multivitamin that is specifically for this age group, which usually contains vitamins A, C and D and comes in drop form. The NHS suggests this for this age group.

Which multivitamins should I take?

Most of the multivitamins we assessed in this project are suitable for adults and children aged 12 and above. 

However, it's important to always read the label to make sure. Check it contains the nutrients that you're concerned about – we were surprised to find some big-brand supplements missing key nutrients. 

For example, iron is an important nutrient and one that many people (especially women) don't get enough of. If you don't eat red meat and are concerned about your iron intake and are opting for a multivitamin, make sure it contains enough iron. 

None of the multivitamins we looked at contained your daily NRV of calcium or magnesium – most have between a quarter and a third of what you need in a day. This is because the daily NRV is relatively high and it's not feasible for manufacturers to include these in one tablet or capsule. If you're especially concerned about calcium or magnesium, you're better off buying a targeted supplement.

If you're choosing a multivitamin as a bit of an 'insurance policy', choose one of our higher scorers, which offer a good range and dose of the necessary nutrients.

Multivitamins are, by their nature, not targeted, and most good choices have a broad range of nutrients in doses that should prevent deficiencies. 

However, we are all different and our diets are different, so one person might need more of one nutrient than another. 

Best multivitamins for men

Men can have higher needs for protein, zinc, magnesium, vitamin D and certain B vitamins.  Zinc and folate are especially important for testosterone and healthy sperm. 

The most recent National Diet and Nutrition Survey, published in June 2025, shows that only 17% of adults meet the five-a-day target for fruit and veg. The Health England Survey published in June 2022 shows that men generally consume lower levels of fruit and veg than women. 

Best multivitamins for women

Calcium and vitamin D are key nutrients as women are at increased risk of osteoporosis in later life. 

Women following plant-based diets can also struggle to get enough vitamin B12 and iodine in their diets. 

If you're menstruating, you will have higher iron needs. Nice estimates that 8% of women in the UK have iron deficiency anaemia, but this figure rises to 12% of premenopausal women and 23% for pregnant women.

When is the best time to take multivitamins?

Supplements have instructions on their labels on how they should be taken – do check these as they will differ and they're important to get the best from the product.

Most multivitamin supplements advise taking them with meals and a drink of water. This is because the fat in your meal will help you absorb the fat-soluble vitamins A, D and E.

Don't take them with tea or coffee – the tannins and caffeine can interfere with the absorption of certain nutrients, including iron and vitamin D. 

Dietitian Sophie Medlin says: 'Some people find that B vitamins, which are in most multivitamins, make them feel mentally energised. If you find this, you might prefer taking them in the morning rather than the evening or bedtime.'

Other than that, the best time to take a supplement is the one that works for you. If it fits into your schedule, you're more likely to remember and it will become habit. 

Who shouldn't take multivitamins?

Over-the-counter multivitamin supplements are relatively low risk and should be safe for most people. However, there are exceptions.

If you're pregnant or trying to conceive, it's important you don't take a general multivitamin but instead choose a targeted pregnancy supplement. Vitamin A is important during pregnancy and is key in developing the baby's eyes, immune system and lungs. However, in high doses (including those found in some supplements), it can cause harm to an unborn baby.  

There are certain nutrients that can interfere with medications, so if you regularly take medicines, you should speak to a doctor, pharmacist or healthcare professional before starting a supplement. For example, vitamin K is important for blood clotting and so can interfere with blood-thinning medications such as warfarin.
