South America Weight Management Supplement Market Size & Share Analysis - Growth Trends And Forecast (2025 - 2030)

South America Weight Management Supplement Market Trends and Insights

Rising obesity rates and lifestyle-related health issues

The growing prevalence of obesity and related health issues is driving a significant increase in the demand for weight-management supplements across South America. In Brazil, for instance, nearly 48% of the adult population is expected to be obese by 2044, while an additional 27% may be overweight, according to the World Obesity Organization in June 2024^{[1]Source: World Obesity Organization, "Almost Half of Brazilian Adults Will Be Living With Obesity Within 20 Years", worldobesity.org}. This highlights the severity of the health challenges in the region. Similar trends are observed across other South American countries, prompting governments and healthcare professionals to promote preventive measures, including metabolic support through supplements, alongside lifestyle changes like improved diets and increased physical activity. The growing use of GLP-1 medications has also shifted the perception of weight management, making it a more medically manageable issue. This shift has brought weight-management supplements into the mainstream, moving them beyond niche fitness markets and integrating them into broader health and wellness routines.

Rising demand for gluten-free, sugar-free, and low-calorie formulations

The demand for gluten-free, sugar-free, and low-calorie products is significantly influencing the weight-management supplement market in South America. Governments in the region are implementing stricter labeling regulations, such as Chile’s black-octagon warnings and Brazil’s updated ANVISA labeling rules, which require brands to reformulate their products to avoid warning labels that could deter consumers. For instance, Integralmedica’s booster energy drink zero açúcar is an example of how companies are adapting by introducing sugar-free options that meet these regulatory standards. This trend is also driven by increasing health concerns, particularly related to metabolic disorders. In Argentina, for example, 14% of adults were living with diabetes in 2024, according to the International Diabetes Federation, highlighting the growing need for healthier, low-calorie alternatives^{[2]Source: International Diabetes Federation, "Argentina", idf.org}. The increasing use of GLP-1 therapies, which help suppress appetite, has created a demand for nutrient-dense, low-calorie supplements that complement these treatments. 

Increasing health consciousness pushing consumers toward preventive nutrition and metabolism-support supplements

Health awareness is growing rapidly in South America, driving the demand for weight-management supplements. People are increasingly turning to daily supplements as a way to maintain their health and reduce the risk of chronic diseases. This trend is also fueled by concerns over rising healthcare costs, prompting individuals to prioritize preventive measures. In Brazil, this shift is particularly evident, as the country allocates 9.7% of its GDP, approximately USD 135 billion, according to the International Trade Administration in August 2025, to healthcare^{[3]Source: International Trade Administration, "Overview", trade.gov}. Both consumers and the government are emphasizing the importance of reducing long-term health risks. To meet this demand, companies are focusing on scientifically proven ingredients, such as chromium picolinate, which supports insulin regulation, and green coffee extract, known for its role in boosting metabolism. These supplements are increasingly being marketed as essential tools for everyday health management, making them more appealing to a broader audience.

Growing participation in fitness and active lifestyles

The increasing focus on fitness and active lifestyles is becoming a major factor driving the growth of South America’s weight-management supplement market. As of February 2025, 78% of people in major metropolitan areas across South America engage in physical exercise at least once a month as per the Health Club Management^{[4]Source: Health Club Management, "New HFA Research Identifies Growth Opportunities For Fitness In Latin America", healthclubmanagement.co.uk}. This indicates a strong post-pandemic trend toward regular physical activity. This growing interest in fitness is driving demand for supplements such as proteins, amino acids, and performance enhancers, which help individuals maintain muscle mass and enhance their workout results. Gym chains such as SmartFit are playing a significant role in this trend. SmartFit has expanded rapidly and diversified its offerings by acquiring brands like Velocity, a spin-studio chain. These gyms are increasing the visibility of supplements by offering them directly within their facilities, making it easier for consumers to access these products. Investments in fitness infrastructure, such as Bluefit’s stake sale to Mubadala Capital, are further supporting this growth. 

Strong competition from functional foods and fortified beverages

Functional foods and fortified beverages are emerging as strong competitors to South America’s weight-management supplement market. Large food and beverage companies are leveraging their well-established brands, widespread shelf presence, and robust distribution networks to introduce products like protein-enriched yogurts, satiety drinks, and meal-replacement options. These products provide similar benefits to supplements but are presented in more familiar and convenient formats, making them appealing to a broader audience. Consumers are increasingly drawn to these functional foods due to their ease of use and integration into daily diets, leading to a shift in spending away from traditional supplements. This trend is particularly evident in key markets such as Brazil, Chile, and Argentina, where fortified beverages and functional foods are rapidly gaining popularity. As a result, supplement manufacturers are facing increasing challenges in maintaining their market share and must innovate to remain competitive in this evolving landscape.

Growing concerns over product safety, adulteration, and unverified ingredients

Concerns about product safety and adulteration are becoming significant challenges for the South American weight-management supplement market. The widespread availability of unregistered and counterfeit products, especially on online platforms, has led to growing consumer distrust. This issue has prompted regulatory authorities, such as INVIMA in Colombia and ANVISA in Brazil, to strengthen their oversight by issuing warnings and updating regulations to combat illegal sales. However, enforcement remains inconsistent, allowing non-compliant products to continue circulating in the market. Even well-known brands are trying to address these concerns by providing voluntary quality or purity assurances. Despite these efforts, the lack of transparency regarding independent lab testing has left many consumers skeptical about product safety. These ongoing safety issues are not only eroding consumer confidence but also slowing the market's growththe the illegal sale of these products, particularly in countries where regulatory enforcement is weaker.

Geography Analysis

Brazil is the largest market for weight management supplements in South America, contributing 62.87% of the regional revenue in 2024. The country’s widespread use of supplements, increasing interest in sports nutrition, and supportive government policies are the primary reasons for its dominance. Gyms and specialty stores play a crucial role in promoting these products, helping consumers understand their benefits and encouraging regular use. The rapid expansion of e-commerce has made supplements more accessible, even in smaller cities, further boosting Brazil’s leadership in the market. This combination of factors ensures Brazil remains a key player in the region.

Colombia is expected to grow the fastest in the region, with a projected CAGR of 10.35%, driven by clear regulations and a growing focus on fitness. Major cities like Bogotá and Medellín are becoming important hubs where gyms and fitness centers actively educate people about the advantages of supplements, leading to higher adoption rates. The increasing awareness of health and wellness, along with a shift toward healthier lifestyles, is fueling demand for weight management products. Chile is also experiencing steady growth, supported by stringent labeling laws that encourage consumers to opt for healthier options, such as sugar-free and high-protein products, which align with modern wellness trends and consumer preferences.

Peru and Argentina are experiencing slower growth due to a stronger preference for traditional herbal remedies and fewer gym facilities compared to other countries in the region. Limited infrastructure and slower adoption of modern health and fitness trends have also contributed to their moderate market expansion. Smaller markets, such as Uruguay, Paraguay, Bolivia, and Ecuador, are still in the early stages of development but show potential for growth as urbanization and retail modernization continue to advance. Chile often serves as a testing ground for clean-label innovations, which are later introduced to other South American markets as consumer preferences evolve and demand for healthier products increases.
