I can also tell you that a combination of EPA GLA, chondroitin, MSM, cod liver oil, ginger oil, and nettle leaf extract may also be just as effective as glucosamine, only not as cost effective. In many cases these have been able to slow and eventually eliminate disease. In fact, glucosamine seems to slow the progression of osteoarthritis, which no other drug claims, says Richy. Another problem that can arise is the onset of type II diabetes from the increased insulin resistance, which has been shown in several studies over the years (11, 12, 13, 14, 15, 16, 17). Out of these four, however, only the sulphate and hydrochloride (HCL) versions are recommended. Opin, (1980), 7, 104, A Drovanti - Vigevano General Hospital, Italy; A. If you're unsure of what this means for the long run, let me explain insulin resistance to you. "It seems to be safe, and it may help in terms of symptoms." Res. This is nothing new, but it means that cutting becomes extremely hard. A. Bignamini - Institute of Biological Chemistry, University of Pavia, Italy; A. L. Rovati - Rotta Research Laboratorium, Milano, Italy; Clinical Therapeutics/Vol. And let us not forget that glucosamine has been shown on several occasions to assist in the up-regulation of leptin levels (22, 23, 24, 25, 26). In other words, glucosamine strengthens your body’s natural repair mechanisms. Copyright © 2019-2029 All Rights Reserved. image caption Does glucosamine help joint pain? Still, taking the supplements and anti-inflammatory drugs at lower doses was more effective at reducing pain than placebo or anti-inflammatory drugs alone, Richy says. "There's been a lot of controversy about this medication," Kwoh tells WebMD. WebMD does not provide medical advice, diagnosis or treatment. Chondrocytes have two methods in which to make GAGs. In turn, this would cause proteoglycan synthesis to also cease. Endocrinology. In the first method, a glucose molecule will be phosphorylised (have a phosphate group added) and will then undergo epimerization reactions (basically changing the configuration of the compound). These, along with chondrocytes and collagen, make up cartilage. There may be as many as 10,000 of these chains on a single proteoglycan molecule – thus we have a super water retainer as these chains make sure all these molecules are away from each other and cannot clump together. J Clin Endocrinol Metab. of Orthopedics-Evangelisches Waldkrankenhaus (Berlin, Germany); Institute for Numerical Statistics GmbH (Koln, Germany); Dept. In addition, the supplements are reported to provide pain relief and greater joint flexibility. 10 (1993). These are what are known as matrixes within the cartilage and this is where the fluid flows. Osteoarthritis is when cartilage becomes worn and exposed bones can rub together. A study does exist showing positive effects from NAG (10), but in general, it is probably best to avoid this type of glucosamine as far as cost-benefit goes. Glucosamine might affect the way your body handles sugar, especially if you have diabetes or other blood sugar problems, such as insulin resistance or impaired glucose tolerance. There are many ways this can happen but it is bad because it overworks the pancreas, causes more insulin to be secreted, and raises the average blood glucose level. More insulin secretion may be anabolic, but it is also very fat storing. When the glucosamine enters the chondrocyte, a phosphorylation reaction occurs forming glucosamine-6-phosphate and from here continues the natural synthesis reactions. If the manufacturer wishes to make glucosamine sulphate, they simply add a sulphur group. and Opinion (1980), 7, 110, G. Crolle, M.D. More information. Ingestion of Glucosamine has been shown to actually stimulate GAG and PG production (1). Over an extended period of time of continuous 'wear and tear' so to speak, you may very well develop osteoarthritis. Glucosamine significantly improved joint space narrowing. Smart Grocery Shopping When You Have Diabetes, Surprising Things You Didn't Know About Dogs and Cats, Coronavirus in Context: Interviews With Experts. Glucosamine is made naturally in the body. This is because when glucosamine is available for chondrocytes, they are able to produce connective tissue faster because they can skip three chemical reactions, needing only a phosphorylation reaction to make glucosamine-6-phosphate. Many people take these supplements, he admits. But the supplements, which are not FDA approved, continue to be controversial. The more Glucosamine at hand means your body has a better chance of decreasing or eliminating pain caused by insufficient lubricants and poor shock absorption. Thus, insulin is only worth taking intravenously. This then provides the chondrocytes with the raw materials necessary (sugar and amino acids) to stimulate the synthesis of GAGs and PGs. Both supplements significantly reduced symptoms such as pain, stiffness, physical functioning, and joint mobility from the two compounds. The glucosamine … the sulphur is basically a 'filler'. It is where more insulin than normal is required to reduce blood glucose (insulin transports nutrients into cells). 2000 Jun;141(6):1999-2002. Res. So, as you can see, chondrocytes are responsible for the synthesis, maintenance, and regeneration of cartilage. 3. Endocrinology. Glucosamine sulfate and chondroitin sulfate are components of natural joint cartilage. Overall safety of glucosamine and chondroitin "can be considered excellent," writes Richy. Instead of being absorbed relatively intact, the intestinal bacteria digest it rapidly and other tissues of the gastrointestinal tract absorb it before it can reach cartilage. Also, when supplementary glucosamine is taken, fibrotic articular tissues begin to heal, improving the potential diffusion of glucose and amino acids through joint capsules and synovial membranes. Chondroitin, glucosamine, and MSM is a combination medicine that has been used in alternative medicine as a possibly effective aid in treating osteoarthritis, muscle damage caused by exercise, and other inflammatory joint disorders. J Clin Endocrinol Metab 2001 May;86(5):2099-2103. What Does It Do? Zhang P, Klenk ES, Lazzaro MA, Williams LB, Considine RV. B. Giustinian', 1st Medical Division, Venice, Italy Curr. of Clinical Pharmacology, Rotta Research Laboratorium, Monza, Italy; Osteoarthritis and Cartilage (1994) 2, 61-69 - The Osteoarthritis Research Society. In a new study, researchers analyze data from 15 studies of these compounds. McClain DA, Alexander T, Cooksey RC, Considine RV. Richy and his colleagues carefully selected only the most reliable studies -- "the best available evidence," he tells WebMD. Symptom improvement began about two weeks after starting the supplements. Firstly, healthy cartilage needs three things: water for lubrication and nourishment, proteoglycans to attract and hold the water, and collagen to keep the proteoglycans in place. This is because when glucosamine is available for chondrocytes, they are able to produce connective tissue faster because they can skip three chemical reactions, needing only a phosphorylation reaction to make glucosamine-6-phosphate. If you're confused as to where this has come from, it's because glucosamine has a dark side. How does Glucosamine and Chondroitin Work: By: Richard Stenlake, Compounding Chemist Article used with permission.Richard Stenlake is a registered pharmacist who owns the largest compounding pharmacy in Australia. Another interesting trait of glucosamine is that unlike other amino sugars, it can be digested and still keep it's primary properties and isn't metabolised like other compounds are. Besides being a building block for the synthesis of proteoglycans, its mere presence acts as a stimulus to the cells that produce proteoglycans. Considine RV, Cooksey RC, Williams LB, Fawcett RL, Zhang P, Ambrosius WT, Whitfield RM, Jones R, Inman M, Huse J, McClain DA. Find out which glucosamine products people are buying. The chemical is the precursor to a substance called … Osteoarthritis Cartilage 1998 May;6 Suppl A:6-13 Protective effect of exogenous chondroitin 4,6-sulfate in the acute degradation of articular cartilage in the rabbit. Glucosamine can slow down the progression of osteoarthritis. The studies in Richy's analysis all focused on osteoarthritis of the knee. These are substances we already consume and are produced in small amounts in our bodies and as such have no known side effects. The N-acetyl-glucosamine (NAG) version yields 81% pure glucosamine. 2001 Oct;142(10):4414-9. Glucosamine and chondroitin occur naturally in the body and are required for the biosynthesis of proteoglycan. Your body is able to manufacture glucosamine on its own, which means it's not an essential nutrient. This can get extremely painful and can even affect the joints of bones throughout the spine, which can also become very dangerous for nerves. The two glucosamines are actually identical in their effects, but the Hydrochloride version is more cost effective as it is a richer source of Glucosamine. © 2005 - 2019 WebMD LLC. This also makes glucose the preferred choice of fuel over stored body fat. Chondoiton Sulfate is a long chain molecule with a negative charge attached to it.
