The global health and wellness industry has witnessed significant transformation in recent years, and the dietary supplements market has emerged as one of its fastest-growing segments. Increasing health awareness, rising prevalence of lifestyle-related diseases, and a growing focus on preventive healthcare are driving strong demand for dietary supplements across the United States and other major economies.
Dietary supplements include vitamins, minerals, proteins, amino acids, herbal extracts, and other nutritional ingredients designed to support overall health and wellness. These products are widely used to fill nutritional gaps, improve immunity, enhance fitness performance, and support long-term well-being.
The U.S. dietary supplements market size was valued at USD 67.09 billion in 2024, growing at a CAGR of 7.9% from 2025 to 2034.
What Is the Dietary Supplements Market?
The dietary supplements market refers to the global industry involved in the production, distribution, and consumption of nutritional products intended to supplement the regular diet. These products are available in various forms such as tablets, capsules, powders, gummies, and liquids.
Dietary supplements are used for multiple health purposes, including immunity support, bone health, digestive health, energy enhancement, and weight management. In recent years, they have also become an essential part of preventive healthcare routines, especially in developed markets like the United States.
