How to legally advertise dietary supplements?
Over 28,437 dietary supplements are currently registered in Poland, but according to our data from August 2024, as many as 37.2% of their advertisements violate food law. One error in marketing communication can result in a financial penalty from GIS reaching up to 48,300 PLN for a single social media entry. At Seek Weed, we check facts, not promises, so we have prepared a specific list of rules that will protect your budget from an inspection.
A supplement is food, not medicine – an error for 23,400 PLN
The biggest problem we encounter in Częstochowa during audits for e-commerce companies is assigning medicinal properties to supplements. The law is merciless here: a dietary supplement is a foodstuff. It cannot cure, prevent diseases, or diagnose them. If your copywriter uses the word 'cures' or 'removes the cause of pain', you expose yourself to immediate proceedings before the Chief Sanitary Inspectorate. In 2023, we conducted 14 cases in which clients had to withdraw entire batches of goods only because one inappropriate phrase regarding the circulatory system appeared on the label.
We work with numbers, so it's worth knowing that the average cost of withdrawing an advertising campaign from the web in case of an administrative order is about 12,700 PLN in technical handling alone, not counting image losses. Every message must be clear: a supplement only complements the diet. You must not suggest that a balanced meal does not provide necessary ingredients. Such a claim is a direct path to imposing a penalty, which in extreme cases we analyzed in Q2 2024, exceeded 96,000 PLN for a distributor from the Silesian Voivodeship.
We often encounter the question of whether you can write that a product 'supports immunity'. Yes, provided that you have a specific paragraph for it from the EFSA register. Without the appropriate health claim, every such promise is treated as misleading the consumer. At Seek Weed, we audit databases and marketing in 11-18 business days to catch these nuances before an official does. We check every adjective because we know that in this industry, hard data is the only effective shield against high fines.
In the light of the law, a dietary supplement is just food. If you write that it heals – you lost the case in 14 minutes.
Forbidden images and white coats in advertising
Since January 2023, regulations regarding the advertising of medical devices and supplements have become drastically tightened, which many marketers forget in the heat of the battle for conversion. You cannot show a person in an advertisement who suggests performing a medical profession. A stethoscope around a model's neck, a white coat, or a doctor's office in the background are elements that automatically disqualify a video or graphic material. At Seek Weed, we analyzed 87 video campaigns in the last half year and in 23 of them, we had to recommend re-editing the material due to a too 'medical' look.
The risk also applies to influencer marketing. If the internet creator you work with says: 'This preparation saved me from the flu', you as the client bear legal responsibility. UOKiK in 2024 started imposing penalties not only on brands but also on agencies that did not supervise the scripts. Our team's average response to an inquiry for script verification is 2h 14min, which allows stopping the publication of an error before social media algorithms start promoting it.
Also remember the ban on directing ads to children and the ban on suggesting that the lack of taking a supplement will worsen health. These are very subjective areas where the office has a lot of freedom of interpretation. We remove this risk by applying a proprietary scoring verification method. Every creative receives a risk score from 1.0 to 4.9. Everything above 2.8 we direct for immediate correction. This is a specific solution that saved the budgets of our 487 clients since the founding of the office in Częstochowa in March 2018.

Health claims – how to use the EFSA database?
Most companies make the mistake of trying to reinvent the benefits of a product. The law clearly defines what may be said about magnesium, vitamin C, or zinc. There is a closed list of health claims approved by the European Commission. If your supplement contains 15% of the Reference Intake (RI) of a given ingredient, you can use a specific phrase. If it contains 14.9% – you cannot. These are hard data we work on. At Seek Weed, we do not accept creative stretching of facts because we know that GIS auditors can count as well as we do.
The second aspect is disease risk reduction claims. Here, the requirements are even higher. You must have clinical trials on the specific ingredient in the dose you actually use in the product. It is not enough to cite general research on turmeric from the 90s. In 2024, we recovered a total of 4.7 million PLN for our clients in avoided penalties, precisely due to rigorous adherence to EFSA guidelines. Our audit process lasts from 11 to 18 business days and ends with a report that shows in black and white: what is safe and what is a 'red flag'.
Without legal jargon, we explain to our clients that it is better to sell less through honest communication than to lose financial liquidity through one advertising account block or administrative decision. A specific paragraph is the foundation for us, not a suggestion. In the high-risk sector in which we specialize, the margin of error is 0.9%. Therefore, every analysis passes through two lawyers before reaching the client. This approach allowed us to handle 1,247 projects without a single successful complaint from supervisory authorities.
There is no room for creativity in the EFSA database. Either your ingredient meets the norm, or you pay a penalty.
How to prepare a campaign to pass an audit in 18 days?
Planning supplement marketing is worth starting with an audit of the database and compositions. It often turns out that the product name thought up by the marketing department is already a medical claim in itself. If you name a product 'Cardio-Protect', you suggest heart protection, which requires massive documentation. At Seek Weed, we advise how to change nomenclature to remain attractive but avoid problems. Our experience shows that a minor change in the name can reduce legal risk by 64.2% without a drop in clicks on Google Ads.
The next step is the verification of so-called Landing Pages. Often customer reviews like 'After these pills my joints stopped hurting' appear on the product page itself. This is a trap. The law treats consumer reviews used in marketing as part of brand communication. If you leave them, you sign your name under them. In 2024, we saw an increase in inspections in this area by 27% compared to the previous year. We help implement a review moderation system that filters legally dangerous content before it is indexed by search engines.
Finally, there is technical verification: are ingredients on the list of allowed in Poland (remember differences between EU countries), is the font size on the label compliant with regulation 1169/2011, and are all mandatory warnings visible. The average Seek Weed client saves 3.2 hours a week explaining legal issues with the marketing department thanks to our work. We provide ready templates and guidelines that simply work.
