The own-label multivitamin is the least fashionable product on a British pharmacy shelf and, in our assessment, the one whose label most often survives close reading. That is not a compliment to the category so much as an observation about what the alternative is charging for.

We are reviewing own-brand multivitamins as a class, against the framework that governs what any of them may say.

What the label has to tell you

The second row is the one that does the work. Because UK labels must express content as a percentage of the nutrient reference value, comparison between two products is arithmetic rather than judgement — a rare situation on any supplement shelf, and the reason this particular category can be assessed honestly.

The case for own-label

The formulations are usually unremarkable in the best sense. A standard multivitamin covering the common vitamins and minerals at or around NRV levels is what most own-label products are, and it is what the category is for. There is little scope for a premium brand to improve on “approximately the reference value of each”.

The claims are usually correctly made. In our reading of these labels, own-label products tend to carry the authorised claim wording, at nutrient levels that meet the conditions of use, without the front-of-pack theatre that surrounds branded equivalents. The register is being used as intended.

Price. The gap between own-label and branded equivalents at similar nutrient levels is frequently large, and nothing on the branded label explains it in nutrient terms.

Availability and consistency. Widely stocked, reliably reformulated to the same specification, and easy to compare because they all report against the same reference values.

The honest limitations

A multivitamin is a broad answer to an unasked question. For most people eating a varied diet, there is no specific reason to take one, and no UK public-health advice recommends the general population do so — unlike vitamin D, which is a separate and better-founded case. This is the largest caveat and it applies to the whole category, own-label included.

Nutrient form varies and is not always disclosed prominently. Different mineral salts differ in absorption, and a percentage of NRV does not capture that. This is where a premium product can occasionally justify itself, and where it usually does not bother to explain that it has.

Interactions between nutrients in a single tablet are real — certain minerals compete for absorption — and no multivitamin label addresses this.

“Not exceeding the stated dose” matters more than it sounds, particularly where someone is taking a multivitamin alongside individual supplements containing the same nutrients. Fat-soluble vitamins in particular accumulate.

None of this is a substitute for a clinician. Anyone with a diagnosed deficiency, a health condition, or a prescription should not be resolving it from a supermarket aisle.

Food supplements are regulated as food in Great Britain, not as medicines. They are not intended to diagnose, treat, cure or prevent any disease and are not a substitute for a varied diet.

Pros and cons

Verdict

Our conclusion is a slightly awkward one for a supplements publication. Own-label multivitamins are good products, correctly labelled, sensibly formulated and fairly priced, and if you have decided to take a multivitamin they are very likely the right thing to buy. We would simply note that the decision to take one is the part nobody has justified to you, and that a plain vitamin D supplement has a public-health case behind it that a multivitamin does not.
