Strategic Drug Licensing Accelerates South Korea Weight‑Management Market Expansion
A surge in obesity and rising demand for effective treatment options underscore the growing need for advanced therapies. For instance, in May 2024, Biocon entered an exclusive licensing and supply agreement with South Korea’s Handok to commercialize synthetic liraglutide, a GLP‑1 peptide injection used for chronic weight management, with Biocon responsible for development and supply and Handok handling regulatory approval and commercialization. With the total addressable market in South Korea estimated at around USD 47 million (IQVIA MAT Q4 2023), this collaboration is poised to significantly elevate market growth by enhancing therapeutic availability and supporting broader adoption across the forecast period.
Major market trends include a rising rate of obesity, scientific innovation, and regulatory approvals.
Science‑Driven Probiotics Boosting Weight Management Market Value in the Region
For instance, in August 2025, AceBiome CEO Myeong Hee Kim revealed that their flagship probiotic strain, Lactobacillus gasseri BNR17, has become the first probiotic approved by South Korea’s Ministry of Food and Drug Safety for reducing body fat. This strain, incorporated into their BNRThin line, has demonstrated measurable reductions in visceral fat and waist circumference in a 12 week randomized, double blind, placebo-controlled study, while also supporting gut health and stable blood glucose levels. As consumer demand grows for evidence-based, multi-functional supplements, this innovation is well-positioned to drive accelerated market growth across the forecast period.
Escalating Obesity Rates Fuel South Korea Weight Loss and Weight Management Market Growth
Rising obesity prevalence and health consciousness are crucial growth drivers. For instance, in March 2024, obesity in South Korea surged to 38.4%, a 1.27-fold increase from 2012, affecting nearly half of men (49.2%) and over a quarter of women (27.8%). Class III obesity also spiked dramatically, especially among young adults, while childhood obesity doubled from 9.7% in 2012 to 19.3% in 2021. These alarming trends are fueling demand for weight‑management diets, supplements, and therapeutic programs, positioning the market for strong expansion in the forecast period.
Weight Loss Supplements to Witness Growth in the Segmentation by Product Type
By product type, the market is segmented into meals, supplements, and beverages, each catering to different consumer needs. Meals, including meal replacements, low-calorie foods, sweeteners, and organic options, hold a significant share due to rising health awareness and busy lifestyles. Weight loss supplements—such as protein, fiber, green tea extracts, and CLA—are gaining traction for their convenience and targeted benefits. Beverages like diet soft drinks, herbal teas, and slimming water appeal to consumers seeking lighter, functional drink options. Overall, the market is driven by increasing obesity concerns, urbanization, and a growing focus on preventive health.
