In South Korea, dietitians are licensed nationally after an exam, and clinical dietitians hold an additional certificate. The health functional food market reached KRW 5.45 trillion in 2024, with domestic production of KRW 4.01 trillion, according to Ministry of Food and Drug Safety data. Functional ingredients must be listed or individually approved by the MFDS.
How the profession is regulated
Dietitians in South Korea hold a national licence issued by the Ministry of Health and Welfare after graduating in food and nutrition and passing the national dietitian examination. A further qualification, the clinical dietitian certificate, is required for clinical nutrition roles in hospitals, with additional training and an examination. Sports dietitian and other specialist certifications are offered by professional bodies.
The Korean Dietetic Association is the professional association. It supports continuing education, specialist certification and advocacy, and works with government on school meals, hospital nutrition and community programmes.
Where Korean dietitians work
School meals are a defining feature. Korean schools provide free lunches, and the law requires school dietitians, many of whom are nutrition teachers who also deliver nutrition education. Large institutional food services in companies, hospitals, the military and care homes must employ dietitians too. In hospitals, clinical dietitians manage nutrition assessment, therapeutic diets and nutrition support teams, and the national health insurance system reimburses some nutrition support activities. Public health centres run nutrition programmes for mothers and infants, older adults and people with chronic disease.
Strengths of the Korean market
- A large, data-rich functional food sector. The health functional food market reached KRW 5.45 trillion in 2024, with domestic production of KRW 4.01 trillion and exports of about KRW 380 billion, according to MFDS figures published by the Korea Health Supplements Association[1].
- Iconic categories. Red ginseng, led by Korea Ginseng Corp. and its CheongKwanJang brand, probiotics, omega-3s, vitamins and eye-health products dominate.
- Advanced manufacturing. Contract manufacturers such as Kolmar BNH supply domestic and international brands.
- Food and bio-ingredient giants. CJ CheilJedang and others produce amino acids, probiotics and specialty ingredients for world markets.
- K-health export appeal. Korean beauty and health brands ride the popularity of Korean culture across Asia and beyond.
Opportunities
For practitioners
An ageing population, rising rates of diabetes and obesity, and a growing focus on community care are increasing demand for clinical and community dietitians. Hospitals are expanding nutrition support teams. The industry hires dietitians for product development, regulatory affairs and consumer education. For foreign dietitians, the national licence and Korean language are prerequisites for clinical practice.
For companies
Korean consumers buy health functional foods through home shopping television, online platforms, pharmacies, department stores and direct-selling networks. Gifting is an important driver, with sales peaking around major holidays. Competition is intense and the domestic market is mature, so Korean brands look abroad, especially to China, Southeast Asia and the United States.
How supplements are regulated
The Health Functional Foods Act, administered by the Ministry of Food and Drug Safety, defines health functional foods as foods made with functional ingredients that support health. Functional ingredients follow two routes: notified (generally listed) ingredients, such as many vitamins, minerals, red ginseng and some probiotics, with set specifications and claims; and individually approved ingredients, which need an MFDS review of safety and efficacy before use. Products carry the health functional food mark, and manufacturers, importers and sellers need business registration. Advertising is reviewed before publication by an industry self-regulatory body. The system is stricter than in the United States and closer in spirit to Japan's.

Public health priorities
National health plans target obesity, diabetes, high blood pressure and sodium intake. Korean diets are traditionally rich in vegetables and fermented foods but high in sodium, so salt reduction is a long-standing priority. The Korea National Health and Nutrition Examination Survey, run by the Korea Disease Control and Prevention Agency, provides detailed national data on diet and health. Free school meals and nutrition education aim to build healthy habits early.
Practical notes
For internationally trained dietitians
Foreign-trained dietitians would need their qualifications recognised to sit the Korean national examination, which is in Korean. Most foreign nutrition professionals in Korea work in research, international schools or industry.
For companies entering Korea
Check whether each functional ingredient is notified or requires individual approval, register as an importer, label in Korean with the health functional food mark, and submit advertising for pre-review. Korean distributors and online platforms are the usual route. Korean buyers attend Asian trade shows such as Vitafoods Asia and Hi & Fi Asia-China; see the events calendar.

How South Korea fits the global picture
Worldwide, 2.6 billion adults were living with overweight in 2024, and 940 million of them with obesity[2]. Diabetes affects 589 million adults aged 20 to 79[3]. The global dietary supplements market was valued at US$209.5 billion in 2025 and is forecast to reach US$431.7 billion by 2033[4]. Those three numbers frame demand for dietitians and nutrition products in every country on the Global Hub.
