It is a fair question to ask before spending money, and it deserves a straight answer rather than a sales pitch.
The short version: most people who take a daily multivitamin have a sensible reason to. Here is how to work out whether you are one of them.
What a multivitamin is actually for
UK health advice is that a varied and balanced diet supplies the vitamins and minerals most people need. That is true, and it is also a description of an ideal week rather than a real one.
Real weeks involve shift work, appetite, budget, travel, illness, kids, and the fortnight where you ate whatever was quickest. A multivitamin is not a replacement for food and no honest seller will tell you it is. What it is, is a floor — a consistent daily baseline underneath a diet that varies like everybody's does.
That is a modest claim, and it is the true one. It is also why multivitamins are the most widely taken supplement in Britain.
Who benefits most
Anyone eating a restricted diet
If you have cut out a food group — vegan, vegetarian, dairy-free, low-FODMAP, or simply eating less than you used to — you have removed the foods that supplied certain nutrients. Vitamin B12 is the clearest case: it occurs almost exclusively in animal foods, and a plant-based diet needs a supplemented source.
Older adults
Appetite tends to fall with age while requirements do not, and B12 absorption becomes less efficient. Both point the same way, and this is one of the strongest cases in the category.
Anyone whose eating is genuinely erratic
Shift workers, carers, people in the middle of something difficult. If your meals are unpredictable, a daily capsule is a sensible piece of insurance — and it takes ten seconds.
People who want the iron and vitamin C pairing
Vitamin C increases iron absorption, and plant iron is harder for the body to take up than iron from meat. A multivitamin containing both puts them in the same capsule, which is a genuinely practical piece of formulation.
Who might want something else instead
A multivitamin is broad by design. If you have one specific thing you want to address, a product built around it will usually do that job better — and we would rather point you at the right pot than sell you the wrong one.
And if you have a diagnosed deficiency, follow what your GP recommends. That will normally be something higher-dose and specific.
The two things to take alongside it
These are the exceptions where UK guidance is unusually direct, and where a general multivitamin is not the whole answer.
Vitamin D, October to March
UK government advice is that everyone should consider taking 10µg of vitamin D daily between October and March, because British sunlight in those months is not strong enough for the skin to make it.
Most multivitamins carry a fraction of 10µg — ours provides 2.5µg, at 50% NRV. So over winter, a dedicated vitamin D alongside your multivitamin is the sensible combination. We do not make one, and I would rather tell you that than have you assume you were covered.
Folic acid, if you might become pregnant
UK advice is 400µg of folic acid daily from before conception until twelve weeks. A pregnancy-specific supplement is the right product for that job, for the folate level and because general multivitamins can contain preformed vitamin A, which UK guidance says to avoid in pregnancy.
If the answer is yes, choose well
The useful test is not how many nutrients are listed but how many are present at a level that counts — we have written about why seventeen can beat fifty, and our buyer's guide compares the formats.
Ours is The One: seventeen vitamins and minerals, every one at 25% NRV or above, nine at a full 100%. Eight of them contribute to the normal function of the immune system. Eight contribute to the reduction of tiredness and fatigue. Nothing in the capsule is there just to lengthen the label.
120 capsules — up to four months at one a day — at £24.99, made in the UK and Halal certified. Suitable for vegetarians, not vegans.
This is general information, not medical advice. If you think you may be deficient in something, speak to your GP. Always read the label. Food supplements are not a substitute for a varied and balanced diet and a healthy lifestyle.
