    Glucosamine is a natural compound found in cartilage– the hard tissue that cushions joints.

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

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


    Research on glucosamine use for particular conditions reveals:.

    Osteoarthritis. Oral use of glucosamine sulfate might supply some pain relief for people with osteoarthritis of the knee. Some research study shows that it might also help slow knee joint degeneration connected with osteoarthritis. More studies are needed to figure out the benefits of glucosamine sulfate supplements for osteoarthritis of the hip, spinal column or hand.

    Rheumatoid arthritis. Early research recommends that oral use of glucosamine hydrochloride might reduce pain related to rheumatoid arthritis. Nevertheless, researchers didn’t see an enhancement in inflammation or the variety of unpleasant or inflamed joints.

    When considering glucosamine, read item labels carefully to make sure you select the appropriate kind. There’s less clinical evidence to support making use of N-acetyl glucosamine in dealing with osteoarthritis, and more research study is required to confirm its benefits. (1 ).


    The body uses glucosamine to build and fix cartilage. Cartilage is a versatile, hard, rubbery connective tissue that secures the bones in the joints. It offers padding and avoids the bones from rubbing together. As individuals age, their cartilage can become less versatile and begin to break down. This can result in pain, inflammation, and tissue damage, which, for instance, occurs in osteoarthritis.

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

    Glucosamine occurs naturally in the body, however levels fall as individuals grow older. In time, the reduction could contribute to joint degeneration. (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 concentrated in connective tissues of the 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 dose of glucosamine sulfate, and is rapidly incorporated into articular cartilage. Glucosamine can be found in numerous kinds, including sulfate, hydrochloride, N-acetyl-glucosamine, or chlorohydrate salt, and as a dextrorotatory isomer. There is some conflict over which form is most reliable. Pooled findings from research studies utilizing a particular business glucosamine sulfate product called Dona recommend that this formula lowers osteoarthritis discomfort, whereas other formulas do not.11 Another research study carried out in China provides some evidence that glucosamine hydrochloride and glucosamine sulfate are equally efficient.

    The sulfate salt of glucosamine types one half of the disaccharide subunit of keratan sulfate, which reduces in clients with osteoarthritis. Hyaluronic acid (found in articular cartilage and synovial fluid) is composed of repeating dimeric systems 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 against degradative processes within the body through transformed gene expression. The specific system of action for the possible impact of glucosamine is unidentified. (3 ).


    In alternative medicine, supporters declare that glucosamine may aid with the following illness:.

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

    Glucosamine has been extensively studied with undetermined outcomes. It may offer health benefits consisting of a decrease in pain, although a 2018 review released in the journal Orthopedics suggests the benefits may be due to 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, particularly in the knee. In spite of some really positive findings, there likewise a lot of evidence opposing these claims.

    An early report released in the Cochrane Database of Organized Evaluations concluded that some preparations of glucosamine may decrease pain and enhance operating in individuals with known osteoarthritis. The research study analyzed 20 randomized regulated research studies involving an overall of 2,570 adults.

    One of the largest glucosamine research studies, sponsored by the National Institutes of Health (NIH), questioned these results. Called the Glucosamine/Chondroitin Arthritis Intervention Trial (GAIT), the two-year research study compared the effectiveness of glucosamine and chondroitin in 662 individuals with knee osteoarthritis and concluded that neither revealed any advantage in easing knee discomfort. Subsequent studies have provided no clearer evidence of any advantages. However, some researchers still contend that glucosamine not only assists alleviate arthritis discomfort however also avoids cartilage loss.

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

    More research study 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 discomfort than a placebo, ibuprofen showed superior to glucosamine.

    Low Pain In The Back

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

    Inadequate Evidence to Rate Efficiency for …

However this item doesn’t appear to assist joint tightness or function. Other early research shows that taking 1500 mg of glucosamine sulfate daily for 28 days does not lower knee discomfort in professional athletes following a knee injury. Nevertheless, it does appear to enhance knee motion.

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

    Jaw pain (Temporomandibular disorder). Some research study shows that taking glucosamine sulfate works about in addition to the nonsteroidal anti-inflammatory drug (NSAID) ibuprofen (Motrin, Advil, etc) For alleviating jaw discomfort. In some individuals, discomfort relief appears to continue for approximately 90 days after glucosamine sulfate is discontinued. Nevertheless, research study recommends that when 1200 mg of glucosamine sulfate is taken by mouth daily for 6 months, jaw pain and the capability to open the jaw are not enhanced.

    The study managed for diet plan, exercise, cigarette smoking, illness history and other attributes.

    ” This is excellent news for individuals who take these supplements,” stated the senior author, Lu Qi, a professor of epidemiology at Tulane University. But prior to advising its use, he added, “we really require additional information from population studies and even more, more solid information from medical trials.”.

    The specific factor for the link is not known, but the researchers recommend that glucosamine might decrease swelling by lowering blood levels of C reactive protein, a sign of inflammation, or by simulating the result of a low-carbohydrate diet, which some studies have recommended is associated with a lower risk of heart disease.

    The scientists note that effectiveness of glucosamine in patients with osteoarthritis and joint pain continues to be discussed. (7 ).
