Expiration date: 2027.3 #Kero List [Proteoglycan] When cartilage is dehydrated, "proteoglycan" and "type II collagen" make up about 90% of it. You may often hear about "glucosamine" and "chondroitin," but they are actually only components that make up part of "proteoglycan." Unlike those components, "proteoglycan," which is the main component of cartilage itself, is a cartilage component with excellent elasticity and water retention due to its characteristic shape and water-collecting properties. [Type II Collagen] The most abundant component of cartilage, excluding water, is "type II collagen." It serves as the foundation component that supports cartilage and also retains nutrients. Based on various research results, "Kitaguni no Megumi" contains proteoglycan and type II collagen in an optimal balance. [Abundant Support Ingredients in Addition to Cartilage Components] In addition to "proteoglycan" and "type II collagen," "Kitaguni no Megumi" also contains "hyaluronic acid," which is one of the cartilage components, and chicken extract containing "imidazole dipeptide," which is attracting attention as a muscle component. Imidazole dipeptide is a muscle component found in animals, and is abundant in the base of migratory birds' wings, supporting daily health.
