Macro drivers include global aging (daily vitamin usage jumps to 58% among 60+ cohorts), personalization tech (AI-driven micro-nutrient panels), and tightening USP & EU GMP standards that are forcing SME exits and M&A. North America retains the largest revenue share (38%), while Asia-Pacific is the fastest-growing region (7.4% CAGR) on surging e-commerce, growing middle-class disposable income, and government anemia- and malnutrition-elimination programs. Competitive intensity is rising as pharma majors (Pfizer, Bayer), consumer-health giants (Reckitt, Unilever), and DTC start-ups bid for shelf space, pushing innovation toward clean-label, sugar-free, and clinically-substantiated SKUs.
