Qualitative and quantitative insights were obtained by interviewing supply-side and demand-side stakeholders during the primary research process. Supply-side sources comprised CEOs, VPs of Product Development, R&D chiefs, regulatory affairs managers, and commercial directors from functional food manufacturers, ingredient suppliers (probiotic cultures, herbal extracts, vitamins), dairy companies, and nutraceutical OEMs. Registered dietitians, nutritionists, category managers from supermarket chains, procurement leads from specialty health stores, medical directors from wellness clinics, and e-commerce platform category chiefs comprised demand-side sources. Market segmentation was verified, new product launch timelines were confirmed, and consumer purchasing patterns, clean-label preferences, pricing strategies, and distribution channel dynamics were gathered through primary research.

Global market valuation was derived through revenue mapping and consumption volume analysis. The methodology included:
• The identification of over 50 key manufacturers in North America, Europe, Asia-Pacific, and Latin America
• Product mapping across herbs & spices, nuts & seeds, fruits & vegetables, dairy-based products, probiotics & prebiotics, and superfood categories
• Analysis of reported and modeled annual revenues specific to immunity-boosting product portfolios
• Coverage of manufacturers representing 75-80% of global market share in 2024
• Extrapolation using bottom-up (consumption volume × ASP by country/region) and top-down (manufacturer revenue validation) approaches to derive segment-specific valuations
• Cross-validation with retail audit data from NielsenIQ, IRI, and Euromonitor International for store-based and non-store-based distribution channels
