Quote: "Glucosamine is a polysaccharide that is found naturally in cartilaginous joint tissues, bones, skin, ligaments, and nails"

Why not just eat natural sources like cartilage, bone broth, skin etc ?

Interestingly most sources I could find on the web say categorically that “No natural food sources of glucosamine exist”, while the the supplement is made from sea shells. All resources related to canine health on the other hand mention cartilage, bone marrow and beef trachea as rich in glucosamine... someone is being dishonest there.

Natural source means made by plants.

This so much. Absorption rate could vary quite a bit and it’s nearly impossible to research and find a good source these days due to insane number of supplement manufacturers in the market (I partly blame Amazon for this).

Glucosamine tablets are made from natural sources, usually seafood (e.g. shells of shrimp, lobsters, and crabs).

I’ve heard that in japan (or at least parts of it) they eat shrimp whole, and it’s kind of amusing when visitors bite off the tails.

Also the little “bones” from certain fish I expect do the same.

There's even snacks that are just the fried fish bones. http://seriouseats.com/2011/03/the-nasty-bits-fried-fish-bon...
