Glucosamine and the Vegan Diet
Glucosamine is a naturally occurring compound found in the fluid around joints, as well as in animal bones, bone marrow, shellfish, and certain fungi. It is commonly used as a dietary supplement to support joint health, particularly in the treatment of osteoarthritis. While many glucosamine supplements are derived from shellfish, it can also be synthetically produced in a laboratory. This makes it important for vegans and those with shellfish allergies to verify the source of glucosamine in their supplements.
