Joint support ingredients

Browse Japanese ingredients by the functional benefit they deliver — brightening, antioxidant, gut health, sleep quality, etc. This page lists 2 ingredients tagged with the Joint support ingredient function, helping formulators and brand planners shortlist candidates by use case rather than by category alone. Examples include Marine Collagen and Salmon Nasal Cartilage-Derived Proteoglycan.

Function claims permitted on a finished product depend on the target market and regulatory pathway (cosmetic, quasi-drug, FFC, Tokuho, dietary supplement). The function tag here is an editorial summary of the ingredient's documented or traditional benefit, not an approved claim. Always verify claim wording against your target-market rules.
