Fish collagen (fish skin & scale), also known as marine collagen, is essentially the superhero of collagens sourced from animals. So what exactly makes fish collagen, a Type I collagen, such a natural gem? To put it simply, it beats other collagens in both bioavailability and absorption thanks to it having the smallest particle size and lowest molecular weight out of all other collagen types. Being incredibly beneficial to the health of your skin (your bodys largest organ) and bones, the glycine- and proline-rich collagen found in fish will impress you as you read more about it!
