AI is creating opportunities for product innovation and consumer engagement in Japan's supplement industry. Platforms driven by AI and automation offer new approaches for consumers to discover and select supplements by utilizing individual-level health data, genetic-level information, and daily habits to create personalized nutrition recommendations. Smart systems combine microbiome data, blood panel data, and activity data to generate a personalized offering of supplements addressing specific health goals, health concerns, and nutritional deficiencies, based on science.
In product development, AI is used to analyze large databases of clinical research studies, ingredient interactions and consumer feedback to identify the most effective combinations of ingredients, predict bioavailability and determine the dosage of each ingredient using data-driven methods to yield maximum health benefits with minimal side effects. By using AI, supplement manufacturers can more effectively formulate supplements specific to the health concerns of Japanese people (e.g., bone health, cognitive health and metabolic health) compared to using trial-and-error methods.
In contrast, artificial intelligence can improve the customer experience. Clever subscriptions, mobile health applications, and interactive platforms provide customers with continuous dietary support and feedback, help improve supplement adherence and monitor health outcomes, and promote personalized recommendations to adapt to changing health conditions. As Japanese consumers, mainly the younger generations, are more accustomed to digital health, acceptance of AI-supported technologies that can integrate with wearables and apps is also increasing. Personalization of health decisions and care will also start to rise. AI-supported consumer markets will close the gap with consumers and help make health outcomes more efficient over time.
Japan's diet supplements market is seeing demand, with preventative health care and functional foods gaining traction. The demand for vitamins and minerals, as well as specialty supplements, is driven by interest in immunity, digestive health, and healthy aging. These factors have contributed to the trend for clean-label, natural, and science-based products and demand for easy-to-take supplements in adults of all ages.
The main drivers of market growth are the aging population of Japan, which drives demand for products related to vitality, joint health, brain health, and chronic disease management. Other drivers include a socially responsible government, the influence of the functional food industry, tailored nutrition, e-commerce, product transparency, and traceability.
