Starting a Supplement Brand Is Not Like Starting a Clothing Brand

By Lee Smith · Published 29 August 2026

Nobody has ever been hospitalised by a hoodie.

That sounds obvious, and it is, but it is the single most important thing a new supplement founder needs to understand and it is almost never said out loud. Every year we speak to people who have built a gym leisurewear line, a fitness app or a coaching business, done well at it, and decided that supplements are the natural next product. The margins look better. The repeat purchase is built in. The customers are already there.

Then they discover that the rules are not the same, and that nobody warned them, and that by the time they found out they had already taken pre-orders.

Where a supplement brand actually sits

A clothing brand trades in consumer goods. If the product is wrong, the outcome is a refund, a bad review and a lesson learned.

A supplement brand trades somewhere between food and pharmaceuticals. The product is swallowed. It enters someone’s bloodstream. It may interact with medication they are already taking, it may be taken by someone pregnant, and it may be taken by an athlete who will be tested next month and whose career depends on what is in the tub matching what is on the label.

That is a different category of risk, and every regulator in every market treats it that way. In the UK and EU, supplements are legally food, but food carrying tightly controlled claims. In the United States they sit under their own framework with mandatory facility registration and manufacturing standards. In Canada they may require a product licence and a number printed on the label before a single unit can legally be sold. In Australia they are regulated as medicines.

None of those systems care how good your brand is. They care whether you followed the process.

The assumption that causes the most damage

Here is the belief we encounter most often, and it is almost always sincere:

“I have appointed a manufacturer. The manufacturer handles the compliance.”

It is an understandable assumption. You are paying a specialist. The specialist holds the certifications, runs the audits, knows the ingredients. Surely the specialist is carrying the regulatory load.

They are carrying part of it, and it is worth being precise about which part.

Your manufacturer is responsible for what is in the tub. That the formulation is made correctly, that it matches the specification, that the facility operates to recognised manufacturing standards, that ingredients are traceable and tested, that the batch is documented and retained.

You are responsible for everything the tub does in the world. Where it is sold, how it is described, who is told what about it, and whether it is legally permitted to be on sale in the country where your customer clicks buy.

A contract manufacturer sells you a product. It cannot sell you permission to sell it.

What actually sits with the brand owner

This is the list that surprises people. Every item on it belongs to you, in almost every market, under almost every contract manufacturing arrangement in the industry.

Market authorisation. Whether the product needs registering, notifying or licensing before sale, and getting that done. This attaches to selling in a territory, not to where the product was made. Moving manufacture to a different country does not remove it.

Importation. If you are selling into a market you do not manufacture in, you need a legal importer with the right licence, established in that country. Not a freight forwarder. An importer of record who carries statutory duties. This is frequently the longest lead item on the whole project and it is discovered last. If the EU is one of your markets, we go deeper in selling UK-made supplements into the EU.

Labelling. Ingredient declarations, allergens, nutritional information, warnings, language requirements, address of the responsible party. The rules differ by market and the label that is legal in Manchester may be illegal in Montreal.

Claims. What you are allowed to say the product does. This is the one that gets brands into trouble fastest, because it is the fun part of the job. An ingredient study is not a study of your product. A permitted claim in one market is a prohibited medicinal claim in another. And a claim that a product prevents injury, treats a condition or improves a disease state moves you out of the supplement category entirely and into a category you are not licensed to sell in.

Consumer information and education. Dosage guidance, who should not take it, what to do if something goes wrong, and a real route for a customer to contact you. If your product ends up in the hands of someone it was never intended for, the question asked afterwards is what you told them.

Adverse event handling. A process for receiving, recording and reporting reactions. Most new brands have none. Most new brands do not know they need one until they need one.

Product liability insurance. Held by you, not inherited from your manufacturer. Their cover protects them.

That is not a manufacturer passing the buck. It is the structure of the entire industry, and it exists for a reason. You are the one placing the product on the market, you are the one making the promises, and you are the one taking the money. The duty follows the profit.

A composite case

A founder comes to us with a strong concept, a real audience and money to spend. The formulation work goes well. The product tastes good, the format is genuinely differentiated, the branding is sharp. The website goes up. Pre-orders open.

Then the market question is asked properly for the first time, and it turns out the product cannot legally be sold in the founder’s home country in the format ordered without a registration process measured in months. No importer has been appointed. The website carries performance figures taken from ingredient research and presented as results for a product that has not yet been manufactured, and lists an active ingredient that is not in the formula.

None of that is caused by bad faith. It is caused by sequencing. Every one of those items was left until after the product was designed, and several of them needed answering before it was designed.

The recoverable version of that story exists, and we have seen it more often than the other kind. It involves the same founder asking three questions six months earlier.

The three questions to ask before you place an order

One. Which markets am I selling into, and what does each one require before I can sell there? Answer this in writing, per market, before the formulation is finalised. It will shape the format, the ingredient list and the dose, and it drives your minimum order quantity and unit cost.

Two. Who is my importer and my regulatory adviser in each of those markets? You need local people. A UK manufacturer can tell you what is in your product. It cannot give you a reliable read on a foreign regulator’s current position, and any manufacturer who confidently does is guessing.

Three. Can I evidence every word on my label and my website? Not “is it probably fine”. Can you produce the evidence, for your product, if a regulator or a competitor asks for it.

If you can answer those three, you are ahead of a large proportion of brands that reach production.

The point of all this

None of this is an argument against starting a supplement brand. It is a good business, the demand is real and there is room for brands with a genuine point of view. We would not do what we do if we thought otherwise.

It is an argument against starting one on the assumptions that work for apparel. The product is different, the liability is different, and the sequence of work is different. Get the market questions answered first, appoint your local people early, and treat your claims as things you have to prove rather than things you get to write.

Do that, and the manufacturing is the straightforward part, and it is the part we can quote you for.
