ストレス緩和

Browse Japanese ingredients by the functional benefit they deliver — brightening, antioxidant, gut health, sleep quality, etc. This page lists 4 ingredients tagged with the ストレス緩和 ingredient function, helping formulators and brand planners shortlist candidates by use case rather than by category alone. Examples include Gamma-Aminobutyric Acid (GABA), Japanese Jujube, Japanese Reishi Mushroom, and L-Theanine.

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.
