The global dietary supplements market size was estimated at USD 192.65 billion in 2024 and is projected to reach USD 414.52 billion by 2033, growing at a CAGR of 8.9% from 2025 to 2033. The market growth is primarily driven by rising health consciousness among consumers, evolving lifestyles, and an increased emphasis on preventive healthcare measures.

The COVID-19 pandemic notably accelerated this trend, as individuals became more focused on strengthening immunity, maintaining vitality, and ensuring overall wellness. One of the key factors contributing to the increased consumption of dietary supplements is the widespread prevalence of nutritional deficiencies. Poor dietary habits, busy schedules, and heavy reliance on processed foods have left many individuals unable to meet their daily nutrient requirements through diet alone.

The aging population is another critical driver of market development. Globally, the population over the age of 65 represents a significant target demographic for dietary supplement companies, contributing substantially to overall industry demand. While the adult population aged 25 to 65 accounts for the highest sales, the geriatric segment shows notably higher market penetration, contributing roughly 30% of worldwide dietary supplement sales.

According to the World Health Organization (WHO), more than 2 billion people worldwide suffer from micronutrient deficiencies, including deficiencies in essential nutrients such as iron, vitamin D, and vitamin B12. In India, studies conducted by the Indian Council of Medical Research (ICMR) reveal that over 60% of the population fails to meet daily nutritional requirements, prompting a growing number of individuals to turn to dietary supplements for corrective and preventive health purposes.

Additionally, the rise of personalized nutrition and functional supplements is reshaping consumer preferences. Technological advancements and growing interest in nutrigenomics have driven demand for supplements designed to address specific health outcomes, such as gut health, cognitive function, stress management, and hormonal balance. Reports indicate that more than 30% of millennials prefer supplements tailored to their unique health needs. Ingredients such as probiotics, nootropics, adaptogens (for example, ashwagandha and ginseng), and herbal extracts are gaining significant popularity due to their targeted health benefits.
