The Inuit don’t see bone disease because their diet is probably high in K2 from the fatty meat and liver of marine mammals.

Osteocalcin helps bind calcium to the bone matrix, ensuring the bones get the calcium they need for strength.nostr:nevent1qqs2tqxqsjaza5y6d3njsumkva56gn60edcn0p42h9xxuatufdxjlxspz3mhxue69uhkummnw3ezummcw3ezuer9wcgn2pyh
