Best Multivitamin UK 2026: 5 Picks and What the Evidence Actually Says

Most multivitamins are sold on a promise they cannot keep. The label implies energy, immunity and general thriving; what the tablet actually does is top up nutrients you might be short of. That is a much smaller claim, and a genuinely useful one if your diet has gaps. It is also worthless if it does not. This guide picks the five multivitamins on Amazon UK that are worth your money, and is honest about the fairly large group of people who should skip the category entirely.

Read this before you buy anything

The evidence on multivitamins in healthy adults is not flattering. The US Preventive Services Task Force reviewed 84 randomised trials and cohort studies and found insufficient evidence that multivitamin supplements prevent cardiovascular disease or cancer, and it actively recommends against beta-carotene and vitamin E for that purpose (USPSTF recommendation). The COSMOS trial, which randomised 21,442 US adults to a daily multivitamin or placebo, found no significant reduction in invasive cancer over a median 3.6 years (COSMOS trial).

So who should bother? People whose diets have real holes. If you skip whole food groups, eat few vegetables, follow a restrictive diet, are on a long calorie deficit, or eat vegan without careful planning, a multivitamin is cheap protection against a shortfall that would otherwise go unnoticed. The NHS's own position is that most people can get what they need from a varied diet, with vitamin D the notable exception (NHS vitamins and minerals).

Vitamin D deserves its own paragraph. UK sunlight between October and March is too weak for your skin to make it, and the NHS advises everyone to consider 10 micrograms a day through autumn and winter. That single recommendation applies to far more people than the rest of the multivitamin category combined, and our best vitamin D supplement guide covers standalone options if your multi falls short.

1. Centrum Advance Multivitamin & Mineral, 180 Tablets: Best Overall

Centrum is the boring answer, and boring is the right answer here. The Advance formula covers just over 20 vitamins and minerals in one tablet a day, including all the B vitamins, vitamin D, calcium, magnesium and iron. It is the most clinically studied multivitamin formula in existence, which is a genuinely meaningful distinction in a category where most products have never been tested at all. The COSMOS trial mentioned above used a Centrum Silver formula.

At around £18 for 180 tablets it works out at roughly 10p a day. It is free from wheat, lactose, nuts and gluten and suitable for vegetarians, though not vegan. The honest criticisms: the nutrient forms are the cheap standard ones rather than the better-absorbed versions, folic acid rather than methylfolate, and the vitamin D dose sits at the low end, so you may still want a separate D supplement over winter. It also contains iron, which most men do not need. For a general-purpose daily multi from a manufacturer with 40 years of formulation behind it, none of that is disqualifying.

2. Nutravita Multivitamin Tablets, 365 Vegan Tablets: Best Value

A full year in one tub for around £20 is about 5p a day, and the formula is not a stripped-back one to get there. You get 26 vitamins and minerals, all eight B vitamins, and 100 percent of the UK nutrient reference value for 21 of them. It is vegan, made in the UK in a GMP-certified facility, and third-party tested for heavy metals and microbiological safety, which is worth more than it sounds in a market where testing is optional.

Nutravita has been going since 2014 and is one of the few Amazon-native supplement brands with genuine scale behind it. The trade-offs are the same as Centrum's: standard nutrient forms, not the premium bioavailable ones. The tablets are also large, and the brand's own advice is to split them if swallowing is difficult, which tells you something. If the cost per day is what decides it for you, nothing else on this list gets close.

3. Inessa Advanced Multivitamin, Methylated, 60 Tablets: Best Premium Formula

This is the one to buy if you have read enough about nutrient forms to care, and it is priced accordingly at around £30 for a two month supply, roughly 50p a day. Everything in it is chosen for absorption rather than cost: folate as active methylfolate (5-MTHF) rather than folic acid, vitamin K as MK-7, and 2000 IU of vitamin D3, which is 50 micrograms and five times the NHS winter recommendation.

It also includes lutein, the carotenoid concentrated in the macula, which almost no mainstream multivitamin bothers with. Doses are set from research rather than from reference values, so several nutrients sit well above the standard 100 percent NRV. That is the point, and it is also the caveat: if you are already taking a vitamin D supplement, a fish oil and a B complex, adding this on top is how you end up over-supplemented. Check the arithmetic across everything you take. Vegan Society registered, made in the UK, and free from gluten, dairy and artificial colours.

4. Nutravita Men's Multivitamins and Minerals, 180 Tablets: Best for Men

Six months for around £20, with 25 vitamins and minerals covering 100 percent NRV for 20 of them, plus 10 micrograms of vitamin D3 and 10mg of zinc. It is vegan, UK-made and GMP-certified, same manufacturing standard as the general formula above.

The pitch is the added maca root and Panax ginseng. Be clear-eyed about this: the botanical extras are the marketing, and the evidence for either at these doses doing much for a healthy man is thin. Buy it for the vitamin and mineral base, which is solid, and treat the herbs as a bonus rather than a reason. One genuine reservation is that this formula contains 14mg of iron. Men without a diagnosed deficiency generally do not need supplemental iron and there is a reasonable argument for avoiding it, so if that concerns you, the Inessa formula is iron-free and the better choice.

5. Vitabiotics Wellwoman Max, 84 Tablets: Best for Women

Vitabiotics is the established British name in this category, more than 50 years old, and Wellwoman is its flagship women's range. Max is the top of that range: a triple pack format combining the core multivitamin with omega-3 fish oil supplying EPA and DHA, plus starflower and evening primrose oil. It runs around £14.50 for 84 tablets, which is a 28 day supply given you take three a day.

The formulation logic makes sense for women who would otherwise buy a multivitamin and a fish oil separately, since bundling them costs less than two products. Zinc and iron support normal cognitive function, and vitamin D, folic acid and selenium support normal immune function, which are the EFSA-permitted claims and roughly the extent of what can honestly be said. Two things to note: it is not vegan or vegetarian because of the fish oil, and three tablets a day is a bigger commitment than one. If you want a simpler single tablet, the Nutravita general formula covers the vitamin side for a fraction of the daily cost.

How to choose

Start with your diet, not the label. If you eat a varied diet with vegetables most days, a multivitamin adds very little. If you do not, it is the cheapest fix available.

Check the vitamin D number. Anything under 10 micrograms leaves you supplementing separately through winter anyway.

Look at the iron. Premenopausal women often benefit. Most men do not, and it is worth actively avoiding.

Nutrient forms matter more than nutrient count. A 26-nutrient formula using folic acid and cheap magnesium oxide is not obviously better than a 20-nutrient formula using methylfolate and citrate. The count is the easiest number to inflate.

Add up everything you take. The realistic risk in this category is stacking. A multivitamin plus a separate D, a zinc and a greens powder can push several nutrients well past sensible.

If you are building a supplement stack around training rather than general health, the things with actual evidence behind them come first. Our guides to creatine, protein powder and omega 3 cover those, and the rest of the nutrition section works through the supplements that do and do not survive scrutiny.
