N-Acetylglucosamine
Most joint and beauty supplements pick a lane: collagen for skin, glucosamine for joints. NAG is built around the molecule the body uses for both — N-acetylglucosamine, an amino sugar present in the connective tissue of skin, joints, tendons and the digestive-tract lining. Yotsuba's formulation pairs it with salmon nasal cartilage extract (non-denatured Type II collagen and proteoglycans), MSM, and Reynoutria sachalinensis (Sakhalin knotweed) — a botanical with deep roots in the traditional medicine of Hokkaido's Ainu people.

ONE MOLECULE, TWO SYSTEMS
Most joint and beauty supplements pick a lane: collagen for skin, glucosamine for joints. NAG is built around the molecule the body uses for both — N-acetylglucosamine, the amino sugar it turns into hyaluronan and the glycosaminoglycans of skin, joints, tendons and the gut lining.
UNIQUELY JAPANESE INGREDIENTS
25 mg of salmon nasal cartilage extract — non-denatured Type II collagen with proteoglycans, produced from the hizu of chum salmon by a heat-free extraction pioneered in Hokkaido. 240 mg of Sakhalin knotweed leaf extract, a botanical from the traditional medicine of Hokkaido's Ainu people. 10 mg of MSM, an organic sulphur compound, completes the set.
LAYERED, NOT MEGA-DOSED
The formulation reflects a quietly Japanese philosophy: rather than mega-dosing one ingredient, layer several at sensible doses, choose forms with documented absorption, and design for long, consistent use. Published research on these matrix ingredients reports outcomes over 8 to 24 weeks — this is a product to live with.
MADE IN JAPAN, FULLY TRACEABLE
ISO certified facility, full traceability on the salmon and crustacean raw materials, no artificial colours, no added sugars, and a deliberately short excipient list. Contains crustacean and fish allergens.
