About this supplement
What Is Glucosamine + Chondroitin?
Glucosamine is an amino sugar: a glucose molecule with an amino group in place of one hydroxyl. The kind in this tablet is made from shellfish shells. The chondroitin sulfate beside it is drawn from bovine cartilage, which is the tissue it belongs to in the first place.
How It Works in the Body
Cartilage is mostly water, held in a mesh of collagen and proteoglycans. A proteoglycan is a protein core with long sugar chains, called glycosaminoglycans, bristling off it.
Chondroitin sulfate is one of those chains. Its sulfate groups carry a dense negative charge, and like charges push each other apart. That repulsion pulls water into the matrix, and it is what lets cartilage take a load. Glucosamine is the amino sugar the body starts from when it builds those chains.
What It Supports
- Cartilage matrix: Chondroitin sulfate is a native building block of cartilage, not a stand-in for one.
- Joint cushioning: Charged sugar chains hold water in the matrix, which is where cartilage gets its spring.
- Building blocks: Glucosamine is the starting material for glycosaminoglycans and hyaluronan.
- Joint structure: Both nutrients support normal joint structure and mobility.
Who It May Suit
Adults who are on their feet all day, or who run, lift or kneel for a living. It is not vegetarian or vegan on two counts: the chondroitin comes from cattle and the glucosamine from shellfish.
Good To Know
A serving is two tablets, and carries 1,500 mg of glucosamine sulfate and 1,200 mg of chondroitin sodium sulfate per serving. The glucosamine is made from crab, shrimp, lobster and crayfish shells. Talk with your healthcare provider before use if you have a shellfish allergy, take warfarin, or are pregnant.

FAQ
Common questions
What is this supplement?
Two of the materials cartilage is built from, in one tablet. Glucosamine is an amino sugar the body uses to make the long sugar chains of connective tissue. Chondroitin sulfate is one of those finished chains, drawn here from bovine cartilage, where it occurs naturally.
How do glucosamine and chondroitin work in the body?
Cartilage holds water inside a mesh of collagen and proteoglycans. Chondroitin sulfate is the charged sugar chain that pulls that water in and keeps it there, which is what lets cartilage take compression. Glucosamine is the amino sugar those chains are assembled from, so the pair covers both the finished part and the raw material.
What makes this combination different?
The forms and the amounts. The glucosamine is delivered as a glucosamine potassium sulfate complex rather than the more common sodium one, and the chondroitin is a sodium salt from bovine cartilage. A serving is two tablets and carries 1,500 mg of glucosamine sulfate and 1,200 mg of chondroitin sodium sulfate per serving.
Who is it for?
Adults who ask a lot of their knees, hips and hands, through sport, through work, or through years of walking on hard floors. It suits people who would rather take the two together than buy them separately. It does not suit vegetarian or vegan eating, and it is not for anyone avoiding shellfish.
What should I know before taking it?
The glucosamine here is made from shellfish, so talk with your healthcare provider before use if you have a shellfish allergy. Mention it too if you take warfarin, which glucosamine has been linked to interacting with, or if you are pregnant or nursing. The chondroitin is a sodium salt and carries sodium with it.
