A chemical found in the body, glucosamine is a supplement sold in various forms, including glucosamine hydrochloride and glucosamine sulfate. But what exactly does glucosamine do, and how can it benefit you? Keep reading to find out how! 

What Is It?

Glucosamine is a naturally occurring sugar in the connective tissues and synovial fluid used to cushion the joints in human and animal bones. There are two types of glucosamine: sulfate and hydrochloride. Glucosamine hydrochloride differs from glucosamine sulfate because it is more concentrated and contains less sodium per dose. 

As an amino sugar, glucosamine is the biochemical precursor of nitrogen-containing sugars. It acts as a joint supplement to treat conditions caused by inflammation that target the cartilage and joints, like osteoarthritis. 

Side Effects & Risks

There are possible side effects and risks associated with glucosamine supplementation. 

Many of these potential risks and side effects are not dangerous, but it is important to consult your doctor before beginning supplementation. Individuals with diabetes should not take glucosamine as it can have a hypoglycemic effect, though there is a low risk in those with type 2 diabetes. 

Glucosamine Side Effects & Risks:

  • Nausea
  • Heartburn
  • Diarrhea
  • Epigastric pain 
  • Constipation 
  • Bloating 

Uses

As a widely used supplement for the joints, many uses of glucosamine are related to inflammation, cartilage, and the joints. 

Glucosamine and chondroitin, which is often sourced from shark cartilage, are often joined together in supplements for believed benefits such as preventing cartilage breakdown. No studies are back on whether these provide more benefits when sourced together in supplements. 

Glucosamine Uses:

  • Osteoarthritis 
  • Rheumatoid arthritis
  • Multiple sclerosis 
  • Joint pain 

Benefits

Many in vitro and in vivo studies demonstrated evidence of exactly how glucosamine helps joint tissues in osteoarthritis patients.

Glucosamine reduces joint pain and is extremely important for promoting joint health. Many athletes, especially runners, like to take glucosamine supplements. The reason is glucosamine’s cartilage breakdown prevention and impact on reducing joint inflammation and pain.
