Rising awareness of personal wellness, shifting consumer habits and a stronger emphasis on preventive health are propelling the market.
The growing health consciousness, accelerated by the COVID-19 pandemic, has encouraged consumers to prioritise immunity, vitality and holistic wellness.

In addition, the increasing adoption of personalised nutrition, driven by advancements in nutrigenomics and digital health technologies, is reshaping consumer preferences.
The market is witnessing demand for targeted supplements that support gut health, cognitive function, stress management, hormonal balance and overall well-being.
Millennials, in particular, show strong interest in supplements with probiotics, nootropics, adaptogens and herbal extracts.
Moreover, the expanding global fitness movement and the rise in active lifestyles among younger consumers are boosting the demand for clean-label, natural and plant-based supplements.
Companies are focusing on greater transparency throughout the supply chain by strengthening ingredient traceability, ensuring sustainable sourcing and adopting eco-friendly packaging solutions.
However, variations in global regulatory standards for dietary supplements may create compliance challenges for manufacturers.
This evolving regulatory environment also presents a positive opportunity for companies to strengthen product quality, enhance transparency and build greater consumer trust, ultimately supporting long-term market growth.
