Glucosamine is a natural compound discovered in cartilage– the difficult tissue that cushions joints.

In supplement kind, glucosamine is gathered from shells of shellfish or made in a laboratory. There are numerous types of glucosamine, including glucosamine sulfate, glucosamine hydrochloride and N-acetyl glucosamine. These supplements aren’t thought about interchangeable.

Individuals utilize glucosamine sulfate orally to treat an agonizing condition triggered by swelling, breakdown and eventual loss of cartilage (osteoarthritis).


Research on glucosamine usage for particular conditions reveals:.

Osteoarthritis. Oral use of glucosamine sulfate may supply some discomfort relief for people with osteoarthritis of the knee. Some research study reveals that it might also assist slow knee joint degeneration associated with osteoarthritis. More studies are required to figure out the advantages of glucosamine sulfate supplements for osteoarthritis of the hip, spinal column or hand.

Rheumatoid arthritis. Early research study recommends that oral use of glucosamine hydrochloride might decrease pain related to rheumatoid arthritis. However, scientists didn’t see an improvement in inflammation or the number of painful or inflamed joints.

When thinking about glucosamine, read item labels thoroughly to ensure you choose the appropriate kind. There’s less medical evidence to support making use of N-acetyl glucosamine in dealing with osteoarthritis, and more research is needed to confirm its benefits. (1 ).


The body utilizes glucosamine to develop and fix cartilage. Cartilage is a flexible, hard, rubbery connective tissue that protects the bones in the joints. It offers padding and prevents the bones from rubbing together. As individuals age, their cartilage can become less flexible and begin to break down. This can result in pain, inflammation, and tissue damage, which, for instance, happens in osteoarthritis.

There is some proof that glucosamine may slow this process and advantage cartilage health.

Glucosamine takes place naturally in the body, however levels fall as individuals grow older. In time, the decrease could contribute to joint deterioration. (2 ).


Glucosamine (2-amino-2-deoxy-β-d-glucopyranose) is an endogenous aminomonosaccharide synthesized from glucose and utilized for biosynthesis of glycoproteins and glycosaminoglycans. Glucosamine is present in almost all human tissues, extremely focused in connective tissues of the human body, and discovered at highest concentrations in the cartilage. In human beings, about 90 percent of glucosamine is soaked up when administered as an oral dosage of glucosamine sulfate, and is quickly included into articular cartilage. Glucosamine can be found in many kinds, consisting of sulfate, hydrochloride, N-acetyl-glucosamine, or chlorohydrate salt, and as a dextrorotatory isomer. There is some dispute over which form is most effective. Pooled findings from research studies utilizing a specific business glucosamine sulfate product called Dona recommend that this solution lowers osteoarthritis pain, whereas other formulas do not.11 Another research study carried out in China offers some evidence that glucosamine hydrochloride and glucosamine sulfate are equally reliable.

The sulfate salt of glucosamine kinds one half of the disaccharide subunit of keratan sulfate, which decreases in clients with osteoarthritis. Hyaluronic acid (discovered in articular cartilage and synovial fluid) is made up of repeating dimeric units of glucuronic acid and N-acetylglucosamine. Possible systems of action for the chondroprotective impact of glucosamine consist of direct stimulation of chondrocytes, incorporation of sulfur into cartilage, and defense versus degradative procedures within the body through modified gene expression. The exact system of action for the possible impact of glucosamine is unknown. (3 ).


In alternative medicine, proponents declare that glucosamine might help with the following health problems:.

  • Diabetes
  • High cholesterol
  • Swelling
  • Inflammatory bowel illness (such as ulcerative colitis)
  • Osteoarthritis
  • Rheumatoid arthritis
  • Temporomandibular joint disorder
  • Health Advantages

Glucosamine has actually been widely studied with undetermined results. It may provide health benefits consisting of a decrease in pain, although a 2018 review released in the journal Orthopedics suggests the advantages might be because of a placebo result.

Here’s a look at some of the crucial research studies and their findings:.


Glucosamine might be of advantage in the treatment of osteoarthritis, especially in the knee. In spite of some very positive findings, there also a great deal of proof opposing these claims.

An early report released in the Cochrane Database of Methodical Reviews concluded that some preparations of glucosamine may minimize pain and improve operating in people with known osteoarthritis. The research study evaluated 20 randomized controlled research studies involving an overall of 2,570 grownups.

Among the biggest glucosamine studies, sponsored by the National Institutes of Health (NIH), questioned these results. Called the Glucosamine/Chondroitin Arthritis Intervention Trial (GAIT), the two-year study compared the efficiency of glucosamine and chondroitin in 662 people with knee osteoarthritis and concluded that neither showed any benefit in easing knee discomfort. Subsequent studies have actually provided no clearer evidence of any advantages. However, some researchers still compete that glucosamine not only helps reduce arthritis pain but also avoids cartilage loss.

According to a six-year study published in Arthritis Care & & Research, cartilage loss appeared to be slowed in grownups with knee osteoarthritis who had taken glucosamine and chondroitin for up to 6 years. The benefits appeared to be higher the longer the supplements are taken.

More research is needed to make sense of these contradictions.


Glucosamine is possibly effective for temporomandibular joint (TMJ) osteoarthritis, according to a little research study released in the Journal of Reseach in Pharmacy Practice. The trial involved 60 adults with TMJ who were provided either glucosamine, ibuprofen, or a placebo for 90 days. Although glucosamine and ibuprofen were both more reliable in relieving pain than a placebo, ibuprofen proved superior to glucosamine.

Low Neck And Back Pain

Glucosamine may not benefit individuals with persistent lower neck and back pain and degenerative back osteoarthritis, according to a 2010 study in the Journal of the American Medical Association. The six-month trial, involving 250 individuals with both conditions, concluded that glucosamine was no much better than the placebo in supplying arthritis discomfort relief. (4 ).

Inadequate Evidence to Rate Effectiveness for …

Joint pain caused by drugs that lower estrogen levels. Early research study suggests that taking a mix of glucosamine sulfate and chondroitin sulfate in 2 or three divided doses daily for 24 weeks minimizes discomfort in females taking drugs that lower estrogen levels for early stage breast cancer.

Unpleasant bladder syndrome (Interstitial cystitis). Early research study suggests that taking a particular product containing glucosamine sulfate, sodium hyaluronate, chondroitin sulfate, quercetin, and rutin (cystoprotek, Tischon Corporation, Westbury, NY) 4 times daily for 12 months reduces signs of uncomfortable bladder syndrome.

Joint pain. Research study shows that taking a specific item consisting of glucosamine sulfate, methylsufonlylmethane, white willow bark extract, ginger root concentrate, Indian frankincense extract, turmeric root extract, cayenne, and hyaluronic acid (Instaflex Joint Assistance, Direct Digital, Charlotte, NC) in three divided doses daily for 8 weeks minimizes joint discomfort. However this item does not seem to assist joint tightness or function.

Knee discomfort. Some research study shows that taking a particular product containing glucosamine sulfate, methylsufonlylmethane, white willow bark extract, ginger root concentrate, Indian frankincense extract, turmeric root extract, cayenne, and hyaluronic acid (Instaflex Joint Assistance, Direct Digital, Charlotte, NC) in three divided dosages daily for 8 weeks decreases joint pain in individuals with knee discomfort. However this product doesn’t seem to help joint stiffness or function. Other early research shows that taking 1500 mg of glucosamine sulfate daily for 28 days does not minimize knee discomfort in professional athletes following a knee injury. Nevertheless, it does seem to enhance knee motion.

Multiple sclerosis. Early research reveals that taking 1000 mg of glucosamine sulfate by mouth daily for 6 months might lower the regression of several sclerosis.

Jaw pain (Temporomandibular disorder). Some research study shows that taking glucosamine sulfate works about along with the nonsteroidal anti-inflammatory drug (NSAID) ibuprofen (Motrin, Advil, and so on) For alleviating jaw pain. In some people, discomfort relief appears to continue for as much as 90 days after glucosamine sulfate is ceased. However, research study suggests that when 1200 mg of glucosamine sulfate is taken by mouth daily for 6 months, jaw pain and the ability to open the jaw are not improved.

Who Should Take Glucosamine/Chondroitin Sulfate?

Numerous patients who suffer from osteoarthritis may take advantage of the positive results of taking this supplement. The uncomfortable symptoms of osteoarthritis might appear when cartilage becomes worn, and exposed bones begin to rub together. Traditional medicine does not yet have a tested treatment to stop or slow the development of osteoarthritis. Standard medical treatment includes drug therapy to manage the pain connected with osteoarthritis.

Duration of treatment has actually not yet been determined.

Reported enhancement (e.g. Decrease in painful symptoms) varies from three weeks to as much as eight weeks.

Some research studies have revealed continued enhancement of symptoms after oral consumption was stopped.

Usually, if there is no discomfort decrease after two months, there is long shot of improvement.

Patients must keep a diary of their symptoms when treatment begins to better judge any modifications in pain level or joint motion, and this information needs to be shared with their doctor. (6 ).

Glucosamine Connected to Heart Advantages

Glucosamine, the dietary supplement widely utilized for arthritic pain, may lower the threat for heart disease, researchers report.

Researchers looked at 466,039 British men and women, ages 40 to 69, who were free of heart disease at the start of the research study. Participants completed comprehensive health questionnaires that consisted of details on using dietary supplements. Nearly 90,000 of them, or 19 percent, reported routine use of glucosamine. The research study, in BMJ, tracked the participants’ health for approximately seven years.

Compared with those who did not utilize the supplement, glucosamine users had an 18 percent lower risk of coronary heart disease, and a 15 percent lower risk of any cardiovascular event. There was a weak association with a decreased risk for stroke.

The research study managed for diet plan, physical activity, smoking, illness history and other qualities.

” This is great news for people who take these supplements,” stated the senior author, Lu Qi, a teacher of public health at Tulane University. But before suggesting its usage, he added, “we actually require extra data from population studies and even more, more solid information from clinical trials.”.

The precise factor for the link is not known, however the scientists suggest that glucosamine might minimize swelling by reducing blood levels of C reactive protein, an indication of inflammation, or by mimicking the result of a low-carbohydrate diet plan, which some research studies have recommended is related to a lower danger of heart disease.

The scientists keep in mind that effectiveness of glucosamine in clients with osteoarthritis and joint discomfort continues to be debated. (7 ).

Natural Sources of Glucosamine

Glucosamine is a natural compound discovered in healthy cartilage– the tough tissue that cushions joints– and especially in the fluid around the joints.

For dietary supplements, glucosamine is harvested from the shells of shellfish (like shrimp, lobster and crab) or made artificially in a laboratory.

There are no healthy food sources of glucosamine besides shellfish shells, per the Mayo Center. But, there are numerous supplements offered. You will often see glucosamine offered in mix with chondroitin sulfate in a supplement kind. (8 ).


The Arthritis Foundation notes an advised dosage of 500 milligrams to 3 grams of glucosamine and chondroitin a day in divided dosages for a minimum of a month.


Think it or not, as specified above there are no health food sources for glucosamine. Whereas many glucosamine supplements are sourced from shells of shellfish (crabs, lobster, shrimp, and so on), there isn’t a list of veggies, fruits, or protein alternatives you can take down on your next grocery list. This is probably another reason that glucosamine supplements are the 2nd most popular dietary supplement taken. In addition, this is why it’s so important to supplement glucosamine in the first place.
