No serious side effects have been reported in large, well-conducted studies of people taking glucosamine, chondroitin, or both for up to 3 years.
Because glucosamine products might be derived from the shells of shellfish, there is concern that the supplement could cause an allergic reaction in people with shellfish allergies. Glucosamine might worsen asthma. There's some concern that glucosamine might raise eye pressure.
Glucosamine can cause some mild side effects including bloating, nausea, diarrhea, and constipation. When applied to the skin: N-acetyl glucosamine is possibly safe when used for up to 10 weeks. When given as an enema (rectally): N-acetyl glucosamine is possibly safe when used in doses of 3-4 grams daily.
Glucosamine should be used with caution in patients with renal impairment; side effects and renal function should be monitored. It is advisable to avoid glucosamine for patients with severe renal impairment and those on dialysis until more data are available.
Glucosamine has been implicated in isolated case reports in causing clinically apparent liver injury, but the role of glucosamine as opposed to other herbal components or contaminants has not been shown, and liver injury due to glucosamine or chondroitin must be very rare if it occurs at all.
The best time to take your glucosamine supplement is… the same time each day, no matter what time that is. With most glucosamine supplements, it is suggested by some experts that you take it with your meals to support digestive health.
Conclusion. In summary, collagen and glucosamine are both essential compounds for maintaining healthy joints, bones, and skin. While collagen provides structural support to the body's connective tissues, glucosamine plays a crucial role in the formation of healthy cartilage.
Glucosamine is extracted from a substance in shellfish. The effects of these supplements on a growing child or developing baby are not yet known. For that reason, glucosamine and chondroitin are not recommended for children, women who are pregnant, women who are nursing, and women who could become pregnant.
Chondroitin is believed to enhance the shock-absorbing properties of collagen and block enzymes that break down cartilage. Like glucosamine, this supplement is thought to help cartilage retain water, keep joints lubricated, and possibly reverse cartilage loss.
Glucosamine and chondroitin are two of the most commonly used supplements for arthritis. They're components of cartilage—the substance that cushions the joints. Research on these supplements has been mixed, in part because studies have used varying designs and supplement types.
Glucosamine and chondroitin protect cells called chondrocytes, which help maintain cartilage structure. In theory, these supplements have the potential to slow cartilage deterioration in the joints, and to reduce pain in the process.
Although glucosamine is unlikely to raise cholesterol levels in most people and is generally considered safe, keep in mind that, in some people, it can cause an allergic reaction, increase eye pressure, and have an anti-coagulant effect.
THE ROLE OF GLUCOSAMINE SULFATE
Glucosamine supposedly plays a part in the repair and maintenance of joint cartilage, stimulating cartilage cells to produce GAGs and proteoglycans.
Glucosamine and chondroitin are non-vitamin, non-mineral supplements which have anti-inflammatory properties. These supplements are typically used for joint pain and osteoarthritis, and are commonly taken as either glucosamine alone or as glucosamine plus chondroitin.
Dietary Sources
There are no major food sources of glucosamine, so you must get it from supplements. Most supplements are made from chitin, the hard outer shells of shrimp, lobsters, and crabs. Other forms of glucosamine are available for people who are allergic to shellfish.
Turmeric can also preserve joint cartilage in the long term. A study involving 160 people with knee osteoarthritis found that turmeric was significantly better than placebo in reducing pain, stiffness and improving joint function.
Collagen is a nutritional supplement made from animal or fish materials. It's rich in amino acids that play an important role in the building of joint cartilage and it may have anti-inflammatory effects.
Glucosamine and chondroitin are supplements that may address joint pain and inflammation caused by arthritis and osteoarthritis. They may cause insomnia as well as headaches that lead to further sleeplessness.
Reported improvement (e.g. reduction in painful symptoms) varies from three weeks to as much as eight weeks. Some studies have shown continued improvement of symptoms after oral intake was stopped. Generally, if there is no pain reduction after two months, there is little chance of improvement.
Interactions between your drugs
No interactions were found between Glucosamine & Chondroitin with MSM and multivitamin with minerals. However, this does not necessarily mean no interactions exist. Always consult your healthcare provider.
Because glucosamine doesn't contain purines, it isn't likely to increase uric acid levels or aggravate gout symptoms. Likewise, there's no clinical evidence that glucosamine helps prevent or treat gout either.
Glucosamine is then phosphorylated to glucosamine-6 phosphate by tissue hexokinases. (4) Several animal and in vitro studies have shown that high doses of glucosamine can induce insulin resistance and raise plasma level of glucose.
At the end of the study, the researchers found that glucosamine significantly reduced stomach bloat and tended to reduce constipation and hard stools. Glucosamine and constipation proved a pairing in the study for providing relief of numerous gut issues.
