Which is the best supplement company in the UK?

Best is a due diligence question, not a popularity one: the five documents that exist for every lawful UK supplement company, and what each one shows

Which is the best supplement company in the UK is a question that gets answered with brand names and should be answered with documents, because a company is a legal entity with a public record and a brand is a word on a tub, and the thing a buyer actually wants to know, whether the company behind the tub is answerable, competent and honest, is written down in five places that anyone can read. This is how a buyer's solicitor or an investor would approach a supplement company, as a due diligence file, and the file is short because the UK requires every food business to leave the same five traces. Document one is the Companies House record, free and public: the date of incorporation, which separates a company trading for a decade from one incorporated last spring; the officers, who are the people answerable; whether the accounts are filed on time, which is the simplest test of whether a company is run properly; and the history of name and address changes, since a company that has changed its name twice has usually had a reason. Document two is the food business registration with the local authority, which every business selling food, supplements included, must hold from 28 days before it begins trading, after which inspection and a hygiene rating follow; it is searchable, and a supplement company that is not registered is trading unlawfully before anything else is asked. Document three is on the label: the food business operator line, which the labelling regulations require, naming the company and address legally answerable for the tub, and which decides who a buyer, a trading standards officer or a court writes to. A label with no UK address, or with only a web address, has failed document three before it is opened.

Document four is the certificate of analysis for the batch in the buyer's hand, obtained by one message quoting the batch number on the tub, and it is the only document in the file that describes the product rather than the company: the laboratory, the analytes tested, the results against limits, and a batch number that matches. A company that sends it within a working day has a quality system that produces it as a matter of routine; a company that sends a generic certificate for another batch, or a paragraph instead, has shown that it does not. The certificate should test for the risk that matters to the product, heavy metals for a mineral or a mushroom, identity and purity for an amino acid or creatine, banned substances under a recognised programme for anything a tested athlete takes, because a certificate for the wrong analyte is a document without a purpose. Document five is the listing and the label read against the authorised claims register: each claim either appears on the register in substantially the words used or it does not, and a company making claims that are not there has told the buyer two things, that it is willing to break the labelling law in public and that its view of the evidence is not the regulator's. Five documents, all free, assembled in under half an hour, and a company that passes all five has shown everything about itself that a buyer can verify, which is more than any ranking shows.

The three meanings of best the question hides and why none of them is in the file, the file applied to a cupboard, the worked example's file opened, and the honest answer

The question hides three meanings of best, and the file measures none of them, which is the point. Biggest: the company with the largest sales, the widest distribution and the heaviest advertising, which is what most answers to the question actually report, and which measures the marketing budget and the retail relationships rather than anything in the five documents; a large company can have an incomplete file and a small one a complete one, and size changes the consequences of a failure rather than its likelihood. Oldest: the company trading longest, which Companies House shows and which is worth something, since a decade of filed accounts is a decade of being answerable, but which does not fill documents four and five, because an old company can test nothing and claim anything. Most trusted: the company whose name is repeated most, which is reputation, and reputation divides into the pile that can be checked, which is the five documents, and the pile that can only be repeated, which is everything else; a buyer who trusts a company because others do has outsourced the file to people who did not open it either. None of the three protects a buyer, because none of them is a document, and the buyer's protection is entirely in the five.

Applied to a cupboard, the file sorts tubs quickly. For each company on the shelf: the Companies House search takes a minute and returns incorporation, officers and filing history; the local authority registration search takes another; the label is read for the operator line in seconds; one message goes out quoting the batch number; and the claims are checked against the register while waiting for the reply. A company that completes the file is one a buyer can continue with; a company that fails document three or five has failed in public on the label itself, and a company that fails document four has failed the only test of the product. The worked example's file is opened here, because a method that runs only on the shelf is a sales pitch: {FL} is sold by a UK company on the public record with its accounts filed; the label carries a UK address and the food business operator line; the tub is UK made under GMP and BRC; the batch certificate for lead, mercury, arsenic and cadmium, the four metals that matter for a mineral, is sent on request for the batch number quoted; and the label carries four authorised magnesium claims and no others, with 1500mg magnesium bisglycinate stated as 300mg elemental at 80% NRV, 180 capsules for £19.99 at 22p a day. The file is complete, and the reader is invited to run it rather than take the paragraph's word, since the paragraph is the house describing the house and the documents are not. The honest answer to which is the best supplement company in the UK is therefore not a name: it is the company whose five documents are complete for the product being bought, which a buyer establishes in half an hour for nothing, and which no ranking, however long, can establish for them.

What to check on the label

Questions people also ask

What is the best supplement company in the UK?

The one whose due diligence file is complete for the product being bought, since a company is a legal entity with a public record rather than a word on a tub: a Companies House record with accounts filed and no history of name changes, a food business registration with its local authority, a food business operator line with a UK address on the label, a certificate of analysis sent for the batch number on the tub, and claims that appear on the authorised register; a company passing all five has shown everything a buyer can verify, and no ranking of brand names shows any of it.

How do I check if a supplement company is legitimate in the UK?

Five free checks: search Companies House for the company named on the label and read its incorporation date, officers and filing history; check that it is registered as a food business with its local authority, which every food seller must be from 28 days before trading; read the label for the food business operator line and a UK address; message the company quoting the batch number on your tub and ask for the certificate of analysis; and read each claim on the listing against the authorised health claims register; a company failing the label or the claims has failed in public, and one failing the certificate has failed the only test of the product.

Does bigger mean better for supplement companies?

No; size measures sales, distribution and advertising spend, none of which appears in the five documents a buyer can verify, and a large company can have an incomplete file while a small one has a complete one; size changes the consequences of a failure, since a recall at scale is a bigger event, rather than its likelihood, and the protection a buyer has is entirely in the documents, the public record, the registration, the operator line, the batch certificate and the lawful claims, whatever the size of the company producing them.

What should a supplement company's certificate of analysis show?

The laboratory that ran it, the batch number matching the one on the tub, the analytes tested with results against stated limits, and a date; the analytes should match the risk of the product, heavy metals, lead, mercury, arsenic and cadmium, for a mineral or a mushroom extract, identity and purity for creatine or an amino acid, and banned substances under a recognised programme for anything a tested athlete takes; a generic certificate for another batch, or a paragraph about quality in place of a document, is a failure of the fourth document.

Is a British supplement company better than an overseas one?

Not by nationality; a UK company is easier to hold answerable, since Companies House, the local authority registration and the operator line all sit within reach of a buyer and of trading standards, and UK made means a facility under UK food law, but the file is what matters rather than the flag, and an overseas company that completes the equivalent documents and prints a UK responsible address on its label has met the same standard; British Supplements as a search term describes a preference for the first, and the preference is only useful if the file is opened.
