Application segmentation dissects the Beverages for Older Adults (45 years +) market by end‑use intent. Hydration (plain, lightly flavored, and electrolyte‑enhanced water) addresses baseline fluid‑balance needs and drives roughly 30 % of total revenue, reflecting the high prevalence of age‑related dehydration risk. Nutritional supplementation comprises protein‑enriched shakes, vitamin‑fortified milks, and mineral‑boosted beverages; this segment contributes about 25 % as consumers prioritize muscle preservation and micronutrient adequacy. Functional health includes drinks formulated for bone‑support (calcium, vitamin D), digestive health (probiotics, fiber), and cognitive wellness (omega‑3, nootropics), accounting for an estimated 20 % of market size due to growing preventive‑health adoption. Therapeutic/Medical drinks—prescribed oral rehydration solutions, low‑glycaemic diabetic beverages, and fortified tube‑feeding liquids—represent roughly 15 % of sales, anchored by clinical reimbursement channels. Finally, Social & leisure (specialty coffees, teas, low‑alcohol cocktails) captures the remaining 10 %, illustrating that even discretionary consumption remains a measurable share of the overall market.
