Over the last two decades, the use of dietary supplements (DS) has grown steadily worldwide, becoming an integral part of preventive healthcare and modern wellness practices. This growth was further accelerated during the COVID-19 pandemic, when concerns over immunity, vaccine shortages, and risks of inflammation drove many people to seek supplements as a complementary approach to protection and recovery.
The dietary supplements market is experiencing strong momentum worldwide. Globally, it is projected to grow from USD 197.8 billion in 2024 to nearly USD 357.6 billion by 2033, advancing at a compound annual growth rate (CAGR) of 6.8%. This growth reflects the increasing demand for a broad range of products, spanning vitamins, minerals, herbal extracts, amino acids, probiotics, fatty acids, and proteins, delivered through tablets, capsules, powders, liquids, and newer consumer-friendly formats.
In India, the market outlook is even more dynamic. Recent estimates suggest that the Indian dietary supplements market will expand from INR 178.6 billion in 2024 to approximately INR 557.7 billion by 2033, at a CAGR of 12.82%. Rising health awareness, urbanization, and a growing focus on preventive healthcare are driving this surge. Like global trends, Indian consumers are embracing a wide mix of supplement types and formats, making them a regular part of daily health routines.
With changing lifestyles, aging populations, and a stronger emphasis on wellness, dietary supplements are steadily shifting from being “optional add-ons” to becoming everyday essentials. People are increasingly turning to these products not only to bridge nutritional gaps but also to boost immunity, support healthy aging, enhance physical performance, and promote overall well-being.

How to Select the Best Dietary Supplements for Yourself
If you’re considering taking a supplement, start by clarifying your purpose. What health issues are you aiming to prevent, improve, or address? With so much information available about global supplements, it can be overwhelming, but following a few key steps can help you make a confident decision.
Consult a professional: Talk to a doctor or registered dietitian to evaluate your needs and determine if supplementation is suitable for you.
Safety and effectiveness: Choose a trustworthy brand known for producing safe supplements. The National Institute of Health’s Office of Global Dietary Supplements provides fact sheets on many supplements, including safety information.
Dosage: Find out the recommended and safe dosage. The Mayo Clinic offers a searchable supplement database that rates effectiveness for various health conditions, discusses safety concerns, and provides dosage guidelines for both adults and children.
Third-party verification: Opt for products labeled as “standardized” from manufacturers involved in programs like the US Pharmacopeia’s Dietary Supplement Verified Program, Banned Substances Control Group, or those bearing NSF International or Informed Choice safety marks. Unlike food or prescription drugs, supplements aren’t regulated as strictly. While manufacturers must follow certain rules, they aren’t required to prove safety or effectiveness or get approval before selling.
A third-party certification seal indicates that a supplement meets specific manufacturing standards, including consistency, cleanliness, and absence of harmful contaminants such as toxins, pesticides, and heavy metals.
With numerous supplement brands and products available, quality is crucial. Always read ingredient lists, warnings, and claims on the label, and conduct independent research. Using these guidelines and consulting with a healthcare professional can help you choose supplements more safely and wisely, supporting your health and well-being.
In conclusion, the global dietary supplements industry is evolving rapidly in size and complexity, with consumer demand fueling innovation across categories and formats. This growth is matched by sophisticated global standards and regulatory frameworks that ensure combined supplements are safe, effective, and trustworthy.
