Is Glucosamine Vegetarian?

Caution

Glucosamine is found in the fluid around the joints, in animal bones, bone marrow, shellfish, and fungi. It can also be made in a lab, so if the label does not provide a source, we recommend calling the manufacturer.

Glucosamine and the Vegetarian Diet

Glucosamine is an amino sugar that is a natural component of the joint fluid in the human body. It plays a crucial role in building cartilage and is often used as a supplement to support joint health, especially in individuals with osteoarthritis. While it can be derived from shellfish, glucosamine is also produced synthetically, which can be suitable for vegetarians and those with shellfish allergies. Consumers should verify the source if dietary restrictions are a concern.
