Why a global hub for nutrition professionals
Nutrition is one of the few health professions that crosses borders every day. A dietitian trained in Manila may work in Dubai, a supplement formulated in New Jersey may be made in Guangdong and sold in Melbourne, and a weight-management clinic in Toronto may follow guidance written in Geneva. Yet the information people need to make good decisions is scattered across regulators, associations, statistics offices and trade-show websites in a dozen languages.
DieticiansWorldwide.com brings it together. The Global Hub has a profile for each of 24 countries: who registers dietitians, whether the title is protected, which association represents the profession, how supplements are regulated, what workforce numbers are published, the strengths of each market and the openings it offers. The industry outlook sizes the four markets that carry the profession, the jobs outlook shows where work is growing, the supplier directory maps manufacturers, wholesalers and retailers country by country, and the events calendar lists the congresses and trade shows worth travelling for.
Who this site is for
- Registered dietitians and nutritionists who want to understand practice rules in another country, compare pay and demand, or plan a move. Start with how to become a dietitian and the country pages.
- Weight-management professionals, including clinicians, coaches and programme operators working alongside the new generation of obesity medicines. Our weight management guide explains where nutrition care fits.
- Supplement brands, contract manufacturers, ingredient suppliers, wholesalers and retailers who sell across borders and need a quick map of the rules and the buyers. See dietary supplements worldwide and the supplier directory.
- Associations at regional, national and international level that want their members, events and continuing education to reach a global audience. The associations page lists the bodies that shape the field.
- Employers and recruiters looking for qualified people, and people looking for nutrition help who want a professional they can trust. You can find a dietitian on our member directory.
How we handle numbers
Health and industry statistics are easy to repeat and hard to check. Our rule is simple: a number appears on this site only if we have read it on the publisher's own page, and it carries a numbered citation that links straight to that page. Where a country, regulator or association does not publish a figure, the page says "not published" rather than filling the gap with an estimate. Market forecasts come from named research publishers and are labelled as forecasts; different publishers use different methods, so we show their numbers side by side rather than blending them. You can see every source in one place on our sources page.
That discipline matters for you as a reader and for the profession. Dietitians are trained to evaluate evidence, and a hub built for them should meet the same standard.
What the numbers say
The demand side is large and still growing. The World Health Organization reports that 2.6 billion adults, 45% of all adults, were living with overweight in 2024, and 940 million of them with obesity[1]. The International Diabetes Federation counts 589 million adults aged 20 to 79 with diabetes and projects 853 million by 2050[2]. Every one of those people benefits from skilled nutrition care.
The supply side is growing too. 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]. The weight-management market was valued at US$190.6 billion in 2025, with a forecast of US$562.2 billion by 2033[8]. The wider wellness economy reached US$6.8 trillion in 2024[5].
And the workforce is expanding to meet it. The International Confederation of Dietetic Associations brings together 50 national associations representing 200,000 dietitian-nutritionists[3]. In the United States, the Bureau of Labor Statistics projects 8% job growth for dietitians and nutritionists between 2025 and 2035, much faster than the average for all occupations[6].
