The global wellness industry has reached a staggering $2.7 trillion, according to the latest research from McKinsey & Company, highlighting a dramatic transformation in how consumers approach health, longevity, fitness, and personal well-being. What was once largely associated with gym memberships, nutritional supplements, and occasional spa treatments has evolved into an enormous global marketplace influencing everything from food and beauty to artificial intelligence, medical diagnostics, and travel.

The findings come from McKinsey’s fifth Future of Wellness research report, which surveyed more than 10,000 consumers across the United States, United Kingdom, Germany, and China. As explored in this Thailand Wellness News report, the research reveals that wellness is increasingly becoming a defining part of personal identity, with consumers demanding more effective products, personalized services, and credible scientific evidence before spending their money.
A $700 Billion American Market Drives Global Expansion
The United States alone accounts for more than $700 billion in wellness spending, with the market expanding approximately 5 to 10 percent annually. This extraordinary growth is attracting substantial investment from major corporations, private equity firms, and consumer brands seeking opportunities in health-related products and services.
McKinsey reports that the six largest transactions involving health and wellness businesses since 2021 were announced or completed in 2025 or later, representing nearly $89 billion in combined deal value.
The industry’s influence is equally apparent in everyday retail. During the first nine months of 2026, approximately 33 percent of newly launched American consumer packaged goods carried wellness-related claims, compared with just 24 percent in 2021.
Among rapidly expanding consumer brands achieving annual growth above 20 percent, 53 percent positioned health and wellness at the center of their offerings.
Wellness Becomes a Powerful Part of Personal Identity
One of the research’s most striking discoveries concerns the growing importance consumers attach to maintaining their health.
Two-thirds of American respondents reported prioritizing wellness more than they did the previous year. Across generations, health and wellness ranked second only to family among important life priorities, surpassing professional achievement and friendships.
More than one-third of American consumers now consider wellness fundamental to their identity.
Although Generation Z and millennials remain particularly influential, older generations are becoming increasingly active participants.
Among baby boomers, the proportion prioritizing wellness increased by 11 percentage points to 49 percent. Their spending now extends across hydration products, home exercise equipment, skin care, and other categories traditionally marketed toward younger consumers.
The research also identified growing interest in optimizing physical performance and extending healthy lifespans.
Approximately 30 percent of American respondents wanted to operate at their physical and mental peak, while more than 40 percent expressed willingness to make substantial efforts to live longer.
Artificial Intelligence Gains Users but Faces Trust Problems
Artificial intelligence is rapidly becoming an important source of wellness information, although widespread adoption has not translated into unquestioning trust.
More than half of surveyed consumers reported using AI for wellness-related purposes, including meal planning, product comparisons, interpreting health information, and obtaining lifestyle recommendations.
Among highly engaged American wellness consumers classified as maximalist optimizers, AI adoption reached 84 percent.
However, 40 percent of American respondents expressed concern that AI-generated health recommendations could be inaccurate.
Human expertise continues to dominate purchasing decisions. Recommendations from friends and family influenced 35 percent of American consumers, while healthcare practitioners influenced 30 percent. AI chatbots influenced only 8 percent.
Interestingly, just 14 percent of AI users reported skipping a doctor’s appointment because of chatbot advice.
These findings suggest that AI’s strongest potential lies in helping consumers understand complicated health information rather than replacing qualified healthcare professionals.
Weight-Loss Medications Reshape Nutrition and Fitness
The growing popularity of glucagon-like peptide-1 medications, commonly called GLP-1 drugs, is creating commercial opportunities far beyond pharmaceutical sales.
These medications are influencing dietary habits, exercise routines, nutritional supplementation, and beauty-related spending.
Among surveyed GLP-1 users, 35 percent reported increasing protein consumption, 19 percent incorporated additional supplements, and 18 percent began strength training.
Such behavioral changes are encouraging food manufacturers, fitness businesses, and wellness providers to develop products addressing muscle maintenance, nutritional requirements, and changing consumer preferences.
Meanwhile, wearable technologies continue expanding their influence.
Approximately 29 percent of American consumers use wellness-focused wearable devices, while as many as half of wearable users purchase premium services, including additional biomarker testing and personalized health insights.
Recovery, Biohacking and Diagnostics Attract Growing Attention
Recovery practices are emerging as another significant wellness category.
Cold plunges, contrast therapy, saunas, and communal recovery experiences increasingly appeal to consumers seeking physical restoration alongside social interaction.
In Germany, 34 percent of respondents had tried or were using saunas and bathhouses, compared with 18 percent in the United States.
Biohacking is also moving beyond specialist communities.
McKinsey found that 18 percent of surveyed consumers actively practiced biohacking, increasing to 28 percent among Generation Z respondents.
Popular approaches include tracking biological measurements, experimenting with supplements, and deliberately increasing consumption of protein, creatine, or fiber.
However, the scientific evidence supporting individual biohacking practices varies considerably, making appropriate guidance and realistic expectations essential.
Consumer diagnostics represent another expanding opportunity. More than half of respondents who purchased at-home testing, advanced imaging, or biomarker services during the preceding year intended to increase their spending.
Significant Opportunities for Thailand’s Wellness Industry
Although Thailand was not included among the four surveyed markets, McKinsey’s findings carry important implications for the country’s expanding wellness economy.
Thailand’s established strengths in medical tourism, traditional therapies, spa services, hospitality, and preventive healthcare provide potential opportunities to serve increasingly sophisticated international wellness travelers.
Hotels and wellness resorts could benefit from combining relaxation experiences with professionally supervised recovery programs, nutritional services, fitness activities, and evidence-based preventive healthcare.
Medical facilities and diagnostic providers may also find opportunities among travelers interested in personalized health assessments and longer-term wellness planning.
However, translating global consumer trends into successful Thai offerings will require attention to medical credibility, transparent pricing, qualified practitioners, and measurable benefits.
The research does not establish Thailand-specific market growth figures or predict how much of the global wellness economy the country could capture.
Scientific Credibility Will Determine Tomorrow’s Winners
Despite enormous commercial expansion, significant consumer needs remain unmet.
Approximately 40 percent of surveyed consumers globally believed existing wellness offerings fell short in areas including longevity, mental health, and mobility.
McKinsey emphasizes that companies must prioritize demonstrable effectiveness, transparent communication, personalized experiences, and trustworthy professional guidance.
Consumers increasingly evaluate whether products genuinely improve their health rather than simply accepting fashionable claims.
The findings ultimately reveal an industry entering a more demanding phase, where scientific credibility could become as commercially important as branding and convenience. For Thailand and other established wellness destinations, the opportunity is substantial, but sustained success will depend on delivering credible health benefits rather than relying on promotional promises. As wellness becomes embedded in everyday lifestyles, businesses capable of combining innovation, accessibility, and genuine effectiveness will be best positioned to benefit from this extraordinary global transformation.
