The Type dimension of Plant-based Protein Bars segmentation distinguishes products by their primary botanical protein source. Soy‑based bars dominate the segment, accounting for roughly 40 % of total volume, driven by established processing infrastructure and high protein density. Pea‑based formulations have captured about 30 % of the market, reflecting consumer preference for non‑GM, allergen‑friendly options and superior amino‑acid profiles. Rice‑based bars, contributing near 15 %, serve niche markets focused on hypoallergenic claims, while Mixed‑legume blends—combining pea, lentil, and chickpea—represent the remaining 15 % and are positioned for functional differentiation through balanced micronutrient content. Each type influences overall market size by shaping supply‑chain dynamics, pricing power, and regulatory compliance, thereby informing strategic investment across sourcing, R&D, and distribution channels within the plant‑based protein sector.
