Food Supplement Advertising Rules in Turkey

Introduction

Food supplements are one of the fastest-growing product categories in Turkey. Vitamins, minerals, collagen products, omega-3 oils, probiotics, herbal extracts, protein powders, amino acids, magnesium products, vitamin D products, multivitamins and similar supplements are widely sold through pharmacies, e-commerce platforms, social media accounts, marketplaces, wellness stores and influencer campaigns. As consumer interest in health, immunity, energy, beauty, sleep, digestion and general well-being increases, advertising in this sector becomes more competitive and more legally sensitive.

The subject of food supplement advertising rules in Turkey is therefore extremely important for manufacturers, importers, distributors, pharmacies, e-commerce sellers, marketplaces, advertising agencies, influencers and foreign brands targeting Turkish consumers. Food supplements may be legally sold as food products, but they cannot be advertised as medicines. This distinction is the core principle of Turkish food supplement advertising law.

The Turkish Ministry of Agriculture and Forestry explains that food supplements are products used to support normal nutrition. They may contain nutrients such as vitamins, minerals, protein, fiber, fatty acids and amino acids, as well as concentrated or extracted forms of plant, animal or bioactive substances. They may be offered in different forms such as capsules, tablets, pastilles, powders, liquid ampoules and dropper bottles. The Ministry also clearly states that food supplements are not medicines and are not used to treat diseases; they are designed to support normal nutrition.

This distinction directly affects advertising. A food supplement advertisement must not create the impression that the product diagnoses, treats, prevents or cures disease. It must not imply that the supplement replaces normal nutrition. It must not mislead consumers through exaggerated health claims, doctor endorsements, fake testimonials, hidden influencer sponsorships, disease-related keywords or misleading e-commerce product descriptions.

In 2026, food supplement advertising became even more clearly regulated within Turkish advertising law. The Ministry of Trade announced that amendments to the Regulation on Commercial Advertising and Unfair Commercial Practices introduced new rules for supplement advertisements. According to the Ministry, food supplements may not be advertised in a way that creates the impression that they replace foods consumed as part of normal nutrition. The Ministry also stated that comparative advertising for these products may be possible except for matters falling within the scope of health claims.

This article explains the legal framework of food supplement advertising in Turkey, the prohibition of misleading health claims, normal nutrition replacement risks, e-commerce and social media advertising, influencer marketing, comparative advertising, consumer reviews, scientific substantiation, Advertising Board sanctions and practical compliance steps for businesses.

What Are Food Supplements Under Turkish Law?

Food supplements are legally treated as food products in Turkey. They are not medicines, medical devices or healthcare services. They are intended to support normal nutrition and are generally offered in measured daily intake forms. This classification is highly important because a product’s legal category determines which advertising claims may be used.

According to the Ministry of Agriculture and Forestry, food supplements are evaluated as food under Law No. 5996 in Turkey and are produced and supervised in accordance with the relevant legislation. The Ministry also explains that food supplements support normal nutrition and do not treat diseases.

In practice, this means that a supplement containing vitamin C, vitamin D, zinc, magnesium, collagen, probiotics or plant extracts cannot be promoted as a medicine merely because consumers associate the ingredient with health. A brand cannot say that the product “prevents flu,” “treats joint disease,” “cures acne,” “eliminates anxiety,” “repairs the immune system,” “treats infertility,” or “replaces medical treatment,” unless such statements are expressly permitted under the relevant health claim framework, which is generally restrictive.

The correct legal approach is to distinguish between lawful product information and unlawful medical implication. A supplement label or advertisement may provide legally permitted information about ingredients, form, daily serving, recommended use and authorized claims. However, the advertisement must not cross into disease treatment, prevention or cure language.

Legal Framework of Food Supplement Advertising in Turkey

Food supplement advertising in Turkey is governed by several layers of law. The first layer is Law No. 6502 on the Protection of Consumers, which regulates commercial advertisements and unfair commercial practices. Under this framework, advertisements must be accurate, honest, transparent and not misleading.

The second layer is the Regulation on Commercial Advertising and Unfair Commercial Practices. This regulation sets out rules on misleading advertisements, hidden advertising, unfair commercial practices, comparative advertising, discount claims, testimonials, social media advertising and other commercial communication issues.

The third layer is sector-specific food and health claim legislation. Food supplements are subject to rules concerning food labeling, consumer information, permitted health claims and supplement-specific requirements. The Advertising Board’s decisions often refer to the Gıda ve Takviye Edici Gıdalarda Sağlık Beyanı Kullanımı Hakkında Yönetmelik, the Sağlık Beyanı Denetimi Hakkında Yönetmelik, the Türk Gıda Kodeksi Gıda Etiketleme ve Tüketicileri Bilgilendirme Yönetmeliği, the Türk Gıda Kodeksi Takviye Edici Gıdalar Tebliği, Law No. 5996 and Law No. 6502 when assessing supplement advertisements.

The fourth layer is enforcement by the Advertising Board, known in Turkish as the Reklam Kurulu. The Advertising Board operates under the Ministry of Trade and supervises commercial advertisements and unfair commercial practices. It may examine advertisements published through television, websites, social media, e-commerce platforms, marketplace listings, brochures, influencer posts and other media.

The Ministry of Trade’s consumer guidance states that advertisements must comply with the principles determined by the Advertising Board, must be accurate and honest, and must not mislead consumers, exploit their lack of knowledge or experience, endanger public health or exploit patients, elderly persons, children or persons with disabilities. The same guidance expressly states that advertisements for foods and food supplements must also comply with sector-specific advertising and promotion rules.

Food Supplements Are Not Medicines

The most important advertising rule is that food supplements must not be presented as medicines. This rule should guide every advertisement, product description, social media post, marketplace listing and influencer script.

A food supplement advertisement should not suggest that the product diagnoses, treats, prevents or cures a disease. Statements such as “protects against viruses,” “prevents flu,” “treats depression,” “cures eczema,” “eliminates joint inflammation,” “helps cancer treatment,” “prevents heart disease,” “treats infertility,” or “works like medication” are highly risky. Even if the product contains ingredients known to support normal bodily functions, the advertisement must remain within legally permitted boundaries.

The Ministry of Agriculture and Forestry’s consumer-facing explanation is very clear: food supplements are not medicines and are not used for the treatment of diseases. This simple sentence should be treated as a compliance principle for every marketing campaign.

The risk is not limited to direct medical words. Visuals may also create a medical impression. For example, white coats, stethoscopes, hospital settings, doctor-like actors, pharmacy consultation scenes, patient recovery stories, before-and-after disease images or references to medical treatment may cause consumers to perceive a supplement as a therapeutic product. Such presentations may be misleading even if the written text avoids the word “cure.”

Prohibition of Health Claims Outside Permitted Scope

Health claims are the most legally sensitive part of supplement advertising. A health claim is any statement or implication suggesting a relationship between a supplement, ingredient or nutrient and health. Examples include claims about immunity, digestion, sleep, bones, joints, skin, hair, energy, fertility, stress, heart health, cholesterol, blood sugar, metabolism or mental performance.

Under Turkish practice, health claims used for food supplements must remain within the permitted legal framework. The Advertising Board’s 2026 bulletin provides concrete examples. In one supplement-related case, the Board noted that the relevant health claim guide lists permitted health claims for certain nutrients, substances, foods or food categories, and that the examined brochure went beyond the permitted health claims. The Board found violations of several provisions, including the health claim regulation, food labeling rules, supplement communiqué provisions, Law No. 5996, the Commercial Advertising Regulation and Law No. 6502.

This is significant because advertisers often believe that “soft” wellness statements are safe. However, even expressions such as “this winter take care of yourself and your family,” “a productive and good sleep is what you need,” or visual scenes involving illness-like symptoms may be treated as health claims depending on context. In one Advertising Board assessment concerning supplement promotions on Instagram and YouTube, the Board referred to the opinion of the Turkish Medicines and Medical Devices Agency and concluded that the overall advertisement contained health claims and went beyond permitted health claims.

Therefore, advertisers should not evaluate supplement claims only word by word. The entire advertisement must be examined as a whole: text, visuals, music, symptoms shown, characters, product timing, influencer language, hashtags, comments, captions and the landing page.

Normal Nutrition Replacement Claims Are Prohibited

A specific 2026 rule concerns normal nutrition replacement. The Ministry of Trade announced that food supplements may not be advertised in a way that creates the impression that they replace foods consumed as part of normal nutrition.

This rule is essential because food supplements are designed to support normal nutrition, not replace it. A supplement advertisement should not imply that the consumer does not need a balanced diet, real food, regular meals or healthy lifestyle habits. It should not suggest that one capsule, sachet or powder provides everything the body needs.

Risky examples include:

“Replaces your daily nutrition.”
“Everything your body needs in one tablet.”
“No need for a balanced diet.”
“Use this instead of breakfast.”
“Your complete daily food alternative.”
“Nutrition in a capsule.”
“Forget meals, take this supplement.”

Even softer statements may be risky if the overall impression suggests replacement. For example, “for those who cannot eat properly, this product solves all nutritional needs” may create a misleading impression. A lawful advertisement should make it clear that the product supports normal nutrition and should be used in accordance with recommended daily intake.

Misleading Supplement Advertising

Misleading advertising is one of the most common legal risks in the supplement sector. Supplement advertisements may mislead consumers through direct false claims, exaggerated benefits, hidden conditions, unauthorized health claims, scientific-looking but unsupported statements, fake consumer reviews or influencer testimonials.

Common risky expressions include:

“Clinically proven result.”
“Guaranteed immunity.”
“Prevents illness.”
“Doctor recommended.”
“Permanent solution.”
“No side effects.”
“100% effective.”
“Natural treatment.”
“Alternative to medicine.”
“Protects your family from seasonal diseases.”
“Cures digestive problems.”
“Fast weight loss without diet.”

A supplement advertisement may also be misleading if it uses general consumer fear. For example, during flu season, a brand may imply that consumers need the supplement to protect themselves from illness. During exam periods, a product may imply that it increases intelligence or academic success. During pregnancy-related marketing, a product may imply medical necessity without proper basis. Such messaging may exploit consumer concerns and create legal risk.

The Advertising Board’s health-related enforcement shows that the Board closely examines supplement advertisements. In its 342nd meeting, the Board focused on food supplements and health claims as a main agenda item. It reviewed 185 files, found 157 unlawful and imposed suspension sanctions with administrative fines totaling 24,016,573 TL. Health-related advertisements, especially food supplements, foods, cosmetics and healthcare services, were specifically stated to be under careful review.

E-Commerce Advertising Rules for Food Supplements

E-commerce is one of the highest-risk channels for supplement advertising in Turkey. Supplements are sold on online marketplaces, pharmacy websites, wellness stores, brand websites, mobile applications and social commerce platforms. Product pages often include product names, ingredient descriptions, consumer reviews, Q&A sections, seller replies, promotional banners, sponsored rankings, search tags and campaign labels.

Each of these areas may create advertising responsibility. A seller may avoid explicit medical claims in the main product description but use disease-related words in the Q&A section. A consumer review may say “this cured my illness,” and the seller may pin or highlight it. A product tag may include “flu,” “anxiety,” “joint pain,” or “hormone balance.” A marketplace advertisement may show a symptom-based search result. All of these practices can create health claim risk.

The Advertising Board’s 369th meeting is particularly important for e-commerce. The Ministry of Trade announced that misleading health claims were frequently made by sellers in electronic marketplace question-and-answer areas. The Board examined disease-treatment expressions concerning vinegar products and imposed administrative sanctions on nine companies.

This example demonstrates that informal marketplace content is not outside advertising law. Sellers and platforms should monitor product descriptions, Q&A answers, consumer comments used promotionally, search keywords and sponsored content. If a statement influences consumers and promotes the product, it may be assessed as advertising.

Social Media and Influencer Advertising for Supplements

Food supplements are frequently promoted by influencers, wellness coaches, athletes, diet content creators, beauty influencers, parenting accounts and lifestyle bloggers. These campaigns may include discount codes, unboxing videos, “daily routine” posts, before-and-after stories, personal testimonials and product recommendations.

Influencer advertising creates two major risks. The first is hidden advertising. If an influencer receives payment, free products, discount codes, commission, event participation or another commercial benefit, the advertising nature of the content must be clearly disclosed. The Ministry of Trade’s guidance states that hidden advertising is prohibited in all communication media.

The second risk is unauthorized health claims. An influencer cannot lawfully say what the brand itself could not say. Statements such as “this supplement stopped me from getting sick,” “this product balanced my hormones,” “this made my child’s immunity stronger,” “this cured my bloating,” or “this helped my depression” may create serious legal risk.

The Advertising Board’s 2026 bulletin includes a social media example involving a supplement product where Instagram content directed consumers to a product while using health-related expressions and failing to include clear advertising or collaboration disclosure. The Board evaluated the content as going beyond permitted health claims and as hidden advertising because consumers were not informed that the content was advertising.

Brands should therefore provide influencers with legally approved scripts. Influencer agreements should prohibit disease claims, treatment claims, guaranteed results, doctor references and fake personal experience statements. The agreement should also require visible advertising disclosure, pre-publication approval, screenshot archiving and immediate correction or removal if a post violates the rules.

Comparative Advertising for Food Supplements

The 2026 amendments introduced an important clarification: food supplements may be subject to comparative advertising, except for matters that fall within the scope of health claims.

This means that a supplement brand may, in principle, compare objective non-health matters such as price, package quantity, dosage form, number of capsules, flavor options, delivery time, packaging type or service features, provided that the comparison is not misleading and complies with general comparative advertising rules. However, comparisons involving health effects are highly restricted.

For example, the following may be risky:

“More effective for immunity than Brand X.”
“Works faster for joint pain.”
“Better for sleep than other supplements.”
“Stronger protection against flu.”
“More powerful hormone balance effect.”
“Best supplement for anxiety.”

These statements compare health-related effects and may fall within prohibited or unauthorized health claim territory. By contrast, a carefully drafted comparison such as “contains 60 capsules per package” or “offered in sachet and capsule forms” may be safer if accurate and not misleading.

Even permitted comparative advertising must be objective, verifiable and fair. It should not denigrate competitors, create confusion, use unsupported superiority claims or mislead consumers by comparing products under different conditions.

Scientific Claims and Evidence

Supplement advertisements often use scientific language. Expressions such as “clinically tested,” “scientifically proven,” “laboratory approved,” “research-backed,” “contains active ingredients,” “high bioavailability,” “expert formula” and “approved by science” may strongly influence consumers. These statements are risky unless properly supported and legally permitted.

The Advertising Board has repeatedly emphasized that claims must not go beyond the permitted health claim framework. In the 2026 bulletin, the Board referred to cases where claims were considered outside permitted health statements, and one assessment stated that where relevant authority approval had not been obtained for the claims used, their scientific accuracy could not be treated as proven and the claims were misleading.

Evidence should be specific to the claim. A study about an ingredient does not automatically prove the effect of the finished product. A study conducted at a different dosage may not support the advertised daily serving. A study involving adults may not support claims directed at children. A general article about vitamin benefits may not justify a brand-specific claim.

Businesses should maintain a claim substantiation file for each product. This file should include permitted claim basis, product composition, label approvals, scientific references, legal review, internal approval records and screenshots of all advertisements. If the Advertising Board requests information, the advertiser should be able to respond quickly.

Doctor, Pharmacist and Expert Endorsements

Doctor, pharmacist, dentist, veterinarian and health institution references are especially sensitive in supplement advertising. Consumers tend to trust health professionals, and such references may create the impression that a product has medical approval or therapeutic effect.

The Ministry of Trade’s consumer advertising guidance states that testimonial advertisements may not include images, statements or references suggesting that doctors, dentists, veterinarians, pharmacists or health institutions make health claims about a product or service.

This means that supplement brands should avoid using white coats, doctor-like actors, pharmacy consultation visuals, medical clinic settings or expert statements in a way that suggests unauthorized health endorsement. Academic titles must also be used carefully because they may create a scientific authority impression.

A supplement advertisement may mention factual, legally required or permitted information, but it should not create the impression that medical professionals recommend the product as treatment or disease prevention.

Weight Loss, Beauty and Immunity Claims

Certain supplement categories create recurring advertising risks.

Weight loss supplements are risky because consumers seeking rapid weight loss may be vulnerable. Claims such as “lose weight without diet,” “burns fat while sleeping,” “detox effect,” “fast slimming,” or “permanent weight loss” may be misleading and unauthorized.

Beauty supplements, especially collagen, biotin, hyaluronic acid and skin-related products, are often advertised with claims about wrinkles, hair loss, skin elasticity and anti-aging. These claims should not be exaggerated or presented as guaranteed results. Before-and-after visuals, filters, AI-edited images and influencer testimonials must be reviewed carefully.

Immunity supplements are especially sensitive during seasonal illness periods. Even if a permitted nutrient claim exists, the advertisement must not imply disease prevention. Visuals showing sneezing, illness, hospital-like scenes or family protection themes may create a broader health claim than intended.

Sleep, stress and mood supplements may also create risk. Claims about anxiety, depression, insomnia, hormonal balance or mental health may quickly enter disease-related territory.

Consumer Reviews and Testimonials

Consumer reviews are powerful in supplement sales. A product with many positive reviews may appear more trustworthy than formal advertising. However, reviews may create legal risk if they contain disease-treatment claims and are used promotionally.

If a consumer writes “this product cured my anxiety,” “my child stopped getting sick,” “my joint pain disappeared,” or “this treated my hormonal problem,” the seller should not highlight, pin, reproduce or use that review in advertising. Once a business uses a consumer statement for promotional purposes, it may become part of the advertisement.

The 2026 amendments also introduced new criteria for consumer reviews. The Ministry of Trade announced that consumer reviews obtained from platforms where purchase verification is not possible may not be published, and where reviews are categorized under product, service, delivery, seller or provider headings, all reviews must be shown clearly and accessibly in the same area.

Supplement sellers should therefore establish review moderation policies. The purpose should not be to hide negative reviews, but to prevent unlawful health claims from being used as promotional content.

Discount Advertising and Supplement Campaigns

Food supplements are often sold through aggressive discount campaigns. “Buy one get one free,” “immune support campaign,” “winter protection bundle,” “family pack,” “limited-time health package,” and “doctor’s choice discount” are common examples. Such campaigns must comply with discount advertising rules and health claim restrictions.

A price discount may be lawful, but the campaign wording must not imply medical necessity or disease prevention. For example, “winter immunity protection package” may be riskier than “winter campaign on selected supplement products,” depending on the context.

If a discount claim is used, the previous price, campaign period and conditions should be accurate and clear. If an influencer shares a discount code, the content must disclose the advertising relationship and explain material conditions such as expiration date, minimum basket amount and product exclusions.

Advertising to Children and Parents

Supplements for children require special care. Parents may be highly sensitive to claims about immunity, growth, appetite, intelligence, school performance, sleep or development. Advertising should not exploit parental anxiety.

Risky claims include:

“Essential for your child’s intelligence.”
“Protects your child from illness.”
“Children using this supplement perform better at school.”
“Prevents seasonal infections.”
“Guarantees healthy growth.”
“Every child needs this.”

Even if a product is suitable for children under food legislation, the advertisement must remain within permitted claims and should not create fear, guilt or medical necessity.

The 2026 amendments also prohibit targeted advertising directed at children through profiling based on personal data. This is relevant for supplement ads shown through apps, video platforms, social media and games.

AI-Generated Supplement Advertising

Artificial intelligence is increasingly used in supplement advertising. Brands may create AI-generated models, synthetic doctors, virtual influencers, AI-written product descriptions, fake testimonials or before-and-after visuals. These practices can create serious legal risk.

If AI-generated content creates the impression of real consumer experience, medical endorsement or product effect, it may mislead consumers. A virtual person should not say “this supplement improved my health” if the experience is fictional. AI-generated before-and-after visuals should not exaggerate body, skin, hair or weight-related results.

The same rules apply regardless of production method. If an AI-generated advertisement contains unauthorized health claims or hidden sponsorship, it may be unlawful. Technology does not reduce the advertiser’s responsibility.

Advertising Board Enforcement and Sanctions

The Advertising Board actively enforces food supplement advertising rules. The Board may order suspension of unlawful advertisements, correction, administrative fines and, in online cases, access blocking measures. The Ministry of Trade explains that the Board may examine misleading or unlawful advertisements upon applications by consumers, institutions and competitors, and may also initiate ex officio examinations.

Food supplement enforcement is not theoretical. The Advertising Board’s 342nd meeting focused on food supplements and health claims. The Board found 157 of 185 files unlawful and imposed significant administrative fines. It also stated that advertisements containing health claims for food supplements, foods, cosmetics and healthcare services were being closely monitored.

For 2026, administrative fines for misleading advertisements and unfair commercial practices may range from 99,339 TL to 39,916,524 TL, depending on factors such as the advertising medium, unfairness of the violation, benefit obtained, harm caused, fault and the violator’s economic situation.

In addition to monetary sanctions, the commercial harm may be substantial. A campaign may be stopped, social media content may be removed, marketplace listings may be affected, influencer relationships may be disrupted, and the brand may suffer reputational damage.

Practical Compliance Checklist for Food Supplement Advertisements

Before publishing a food supplement advertisement in Turkey, businesses should ask the following questions:

Is the product clearly presented as a food supplement, not as a medicine?

Does the advertisement avoid disease treatment, prevention or cure claims?

Does the advertisement avoid suggesting that the supplement replaces normal nutrition?

Are all health-related statements within the permitted claim framework?

Are claims supported by reliable documents and legal review?

Does the advertisement avoid doctor, pharmacist, clinic or medical endorsement impressions?

Are influencer posts clearly disclosed as advertising?

Do influencers avoid personal disease-treatment stories?

Are e-commerce Q&A sections, product descriptions, reviews and tags monitored?

Are consumer reviews verified and not used to promote unlawful health claims?

Are discount claims accurate and not linked to disease fear?

Are comparative claims limited to non-health matters unless legally permitted?

Are children and parents protected from manipulative messaging?

Are AI-generated visuals, characters or testimonials reviewed?

Are screenshots, approvals, evidence and publication records preserved?

This checklist should be applied before publication. In food supplement advertising, later correction may reduce harm but may not eliminate liability.

Best Practices for Businesses

A strong compliance system should begin with claim control. Businesses should create an approved claim library for each supplement product. Marketing teams, agencies and influencers should be instructed to use only approved claims.

Every advertisement should be reviewed as a whole. A caption may be legally acceptable alone, but the image, video, music, comments and landing page may create a health claim when combined. Social media stories and reels should be archived because they may disappear after publication but still be subject to complaints.

Brands should train influencers and sales teams. Many violations occur because influencers, customer service representatives or marketplace sellers use informal health language. Training should include prohibited words, permitted claims, disclosure obligations and examples of risky statements.

E-commerce monitoring is essential. Sellers should check product titles, descriptions, search keywords, Q&A sections and consumer reviews. Marketplaces should create systems to prevent disease-related supplement claims from being published.

Conclusion

Food supplement advertising rules in Turkey are strict because these products directly affect consumer health perceptions. Food supplements are not medicines; they are food products intended to support normal nutrition. They must not be advertised as treating, preventing or curing diseases, and they must not be presented as replacing normal foods consumed as part of a balanced diet.

The 2026 amendments clarified two important points: food supplements cannot be advertised in a way that creates the impression that they replace normal nutrition, and comparative advertising may be possible except for matters falling within the scope of health claims.

For businesses operating in Turkey or targeting Turkish consumers, supplement advertising should be treated as a high-risk legal compliance area. The Advertising Board closely monitors health claims, e-commerce content, social media promotions and misleading supplement advertisements. Enforcement decisions show that unauthorized health claims, hidden influencer advertising and marketplace Q&A statements may lead to sanctions.

The safest strategy is clear: advertise food supplements as supplements, not as medicines. Use only permitted and substantiated claims. Avoid disease language. Do not exploit consumer fear. Do not imply replacement of normal nutrition. Make influencer sponsorships transparent. Monitor e-commerce content carefully. Keep evidence before publication.

A compliant food supplement advertising strategy protects consumers, reduces regulatory risk and strengthens brand credibility. In the Turkish market, lawful supplement advertising is not only about avoiding fines; it is about building consumer trust through accurate, responsible and transparent communication.
