Nutrition industry growth today and over the next ten years

The four markets that carry the profession

Dietitians and nutritionists work at the meeting point of health care and consumer spending, so the industry around them has more than one engine. We track four:

• Dietary supplements: vitamins, minerals, botanicals, proteins, probiotics, omega-3s and specialty ingredients sold to consumers through pharmacies, health stores, gyms, practitioners and online.
• Weight management: meal replacements, programmes, digital coaching, clinic services and, increasingly, the nutrition care that surrounds prescription obesity medicines.
• Clinical (medical) nutrition: oral nutrition supplements, enteral and parenteral feeds, infant and paediatric formulas for medical use and foods for special medical purposes, prescribed or recommended in hospitals, care homes and the community.
• The wellness economy: the wider spend on healthy eating, physical activity, mental wellness, personal care and preventive health that frames how people buy nutrition.

Dietary supplements: a market heading past US$400 billion

Two research publishers that update their models regularly put the global dietary supplements market at a little over US$200 billion in 2025. Grand View Research values it at US$209.5 billion in 2025 and forecasts growth from US$228.2 billion in 2026 to US$431.7 billion by 2033, a compound annual growth rate of 9.5%^[1]. Precedence Research puts 2025 at US$203.42 billion and forecasts US$430.39 billion by 2035, growth of 7.78% a year^[2]. The two forecasts use different end years and methods, so the honest reading is that both expect the market to roughly double over the next decade.

Consumer behaviour supports that view. The Council for Responsible Nutrition's 2024 survey of 3,194 US adults found that three-quarters of Americans take dietary supplements^[3]. Use is high and stable, and the growth comes from specialty products: gut health, healthy ageing, sports and active nutrition, women's health, sleep and stress, and supplements designed to support people taking GLP-1 medicines.

Country markets show the same pattern. In France, the supplements trade body Synadiet reports a market of €2.9 billion, served by 400 companies employing 16,000 people^[4]. Italy's industry association Integratori & Salute estimates annual sales of €4.5 billion^[5]. In Australia, Complementary Medicines Australia sizes the complementary medicines supply chain at A$6.3 billion in 2025, rising to A$7.44 billion by 2030^[6]. South Korea's health functional food market reached KRW 5.45 trillion in 2024 according to Ministry of Food and Drug Safety data published by the Korea Health Supplements Association^[7].

What drives supplement growth

1. Ageing populations. Bone, joint, eye, heart and cognitive health products grow with every additional older adult, particularly in Japan, Western Europe, South Korea and China.
2. Self-care and prevention. People increasingly manage their own health between appointments, and supplements are the most accessible tool.
3. E-commerce and direct-to-consumer brands. Online channels lower the cost of launching a brand and make cross-border sales routine.
4. Science-led premium products. Clinically studied ingredients, practitioner-only ranges and personalised nutrition command higher prices.
5. Emerging-market middle classes. India, Southeast Asia, the Gulf and Latin America add millions of first-time buyers each year.

The risks that come with growth

Fast growth attracts weak products and bold claims. Regulators respond: Japan tightened its Foods with Function Claims system after the 2024 recall of red yeast rice (beni-koji) supplements, and enforcement on unapproved health claims is rising in the EU, the UK, Australia and the Gulf. For brands, the lesson is that compliance and evidence are now competitive advantages. For dietitians, it is an opening: practices, retailers and manufacturers all need people who can read a study and translate it into an honest label or recommendation. Our supplements guide explains how the rules differ by country.

Weight management: medicine has changed the market

The weight-management market was valued at US$190.6 billion in 2025 by Grand View Research, which forecasts growth from US$221.7 billion in 2026 to US$562.2 billion by 2033, a compound annual growth rate of 14.2%^[8]. That is the fastest growth of the four markets we track, and the reason is clear: medical treatment for obesity has arrived at scale.

IQVIA reports that, as of the second quarter of 2025, 11 million unique patients in the United States were using a GLP-1 medicine across all indications. Before 2022, only 1.8% of patients diagnosed with obesity had started anti-obesity treatment^[9]. IQVIA also found that in the first quarter of 2025, 29% of patients with four additional conditions filled a GLP-1 prescription within six months of diagnosis^[10].

This does not shrink the role of nutrition. It moves it. People on these medicines eat much less, so the quality of what they do eat matters more: adequate protein to protect muscle, enough fibre and fluid to manage gastrointestinal side effects, and a plan for when treatment stops. The Global Wellness Institute notes that the weight-loss services market contracted by 1.1% in 2024 as GLP-1 use boomed^[11]. Traditional diet programmes are under pressure; services that combine medication with nutrition and behaviour support are growing. Read more in our weight management guide.

Clinical nutrition: the hospital and community engine

Global Market Insights estimated the clinical nutrition market at US$58.6 billion in 2024 and forecasts growth from US$63.7 billion in 2025 to US$161.2 billion in 2034, a compound annual growth rate of 10.9%^[12]. Clinical nutrition includes oral nutrition supplements for people at risk of malnutrition, tube feeding, parenteral nutrition and specialised formulas for conditions such as kidney disease, diabetes and cancer.

Demand comes from older populations, more people living with chronic disease and better screening for malnutrition in hospitals and care homes. This is the market most closely tied to dietitians' clinical work: they screen, prescribe, monitor and adjust nutrition support every day. Large players include Nestlé Health Science, Danone Nutricia, Abbott Nutrition and Fresenius Kabi, with strong regional manufacturers in Asia and Europe. The European Society for Clinical Nutrition and Metabolism (ESPEN) and the American Society for Parenteral and Enteral Nutrition publish the guidelines that shape practice.

The wellness economy: the context for everything else

The Global Wellness Institute measured the global wellness economy at US$6.8 trillion in 2024, growth of 7.9% on 2023, and forecasts US$9.8 trillion by 2029, growth of 7.6% a year^[11]. Healthy eating, nutrition and weight loss is one of the institute's largest mature sectors, and it grew at roughly 5% a year from 2019 to 2024^[11].

Wellness spending sets consumer expectations. People who pay for fitness apps, sleep trackers and functional foods expect nutrition advice that is personal, digital and convenient. Dietitians who offer telehealth, app-based monitoring and group programmes are better placed to meet that demand than those who only see patients in person.

The health burden behind the demand

Markets grow because needs grow. The World Health Organization reports that in 2024, 45% of adults, 2.6 billion people, were living with overweight, and 940 million adults, 16% of all adults, were living with obesity. Overweight also affected 35 million children under five and 400 million children and adolescents aged 5 to 19^[13]. The WHO counts 830 million people living with diabetes, up from 200 million in 1990^[14]. The International Diabetes Federation reports 589 million adults aged 20 to 79 with diabetes in 2024, projects 853 million by 2050, and notes that global diabetes-related health spending passed US$1 trillion for the first time in 2024^[15].

National figures show how much this varies. WHO's Global Health Observatory estimates adult obesity in 2022 at 39.5% in Saudi Arabia, 36.1% in Mexico, 31.8% in the United Arab Emirates, 31.1% in South Africa, 28.2% in Brazil and 7.2% in India^[16]. High-prevalence countries need clinical capacity; lower-prevalence, fast-growing countries such as India need prevention at very large scale.

What the next ten years mean for dietitians

Put the four markets together and the direction is clear. The work available to qualified nutrition professionals is widening in five ways:

1. Clinical roles grow with ageing and chronic disease. Hospitals, renal units, oncology centres, long-term care and home care all need more dietitians. In the United States, employment is projected to grow 8% between 2025 and 2035, with about 5,700 openings a year^[17]. See the jobs outlook.
2. Medical weight management needs nutrition specialists. Every GLP-1 prescription creates a need for protein, fibre, hydration and maintenance planning.
3. Industry hires evidence experts. Supplement, clinical nutrition and food companies employ dietitians in regulatory affairs, medical and scientific affairs, product development, education and sales.
4. Digital care keeps expanding. Telehealth, app-based coaching and remote monitoring open roles that are not tied to one city.
5. Global mobility is rising. Countries with workforce gaps recruit internationally trained dietitians through defined registration routes. Each country page explains the route.

What the next ten years mean for companies

For brands, manufacturers, wholesalers and retailers the opportunities are equally clear, but so are the obligations:

• Evidence wins. Products backed by human studies, honest dosing and clear labels earn practitioner recommendations, which drive repeat sales.
• Compliance is market access. Each country has its own notification, registration or licensing route. Building that knowledge in-house, or hiring dietitians and regulatory specialists who have it, shortens time to market.
• Practitioner channels grow. Practitioner-only ranges and partnerships with clinics and dietitians are among the fastest-growing routes to market in Australia, the UK and North America.
• Emerging markets reward patience. India, Southeast Asia, the Gulf and Latin America are large and growing, but registration, distribution and pricing need local partners. Our supplier directory and events calendar are good places to start.

Reading market forecasts critically

Market research forecasts are useful, but they are models, not measurements. Before you rely on one, check four things: what the publisher includes in the market (for example, whether sports nutrition or functional foods are counted), the base year, the forecast period, and whether the figure is retail value or manufacturer revenue. Two forecasts for the same market can differ by tens of billions of dollars for those reasons alone. That is why we show figures from more than one publisher where we can, label each with its source and year, and never average them.
