Chondroitin and glucosamine: a detailed review of dietary supplements for joint health

I. Fundamentals of chondroitin and glucosamine:

A. What is chondroitin?

  1. Definition: chondroitin sulfate is glycosaminoglican (GAG), a complex molecule consisting of repeating sugars. This is a natural component of cartilage, fabrics that amortizes the joints and allows them to move smoothly.

  2. Chemical structure: chondroitin sulfate consists of a chain of alternating sugars, n-acetylgalactosamine and glucuronic acid. These sugars are sulfate, which gives the molecule a negative charge. This sulfation plays an important role in its biological activity. There are various types of chondroitin sulfate, designated by letters (for example, chondroitin sulfate a, c, d, e), each of which has slightly different structures and properties.

  3. Functions in the body:

    a. Support for cartilage: chondroitin helps to keep water in cartilage, ensuring its elasticity and compression resistance. It also supports the synthesis of new cartilage components, such as collagen and other Gaga.

    B. Inhibition of enzymes that destroy cartilage: chondroitin can suppress the activity of enzymes, such as matrix metal proproteinase (MMP), which are involved in the destruction of cartilage tissue in osteoarthritis.

    C. Anti -inflammatory effect: chondroitin has moderate anti -inflammatory properties that can help reduce pain and joint inflammation. The mechanism of this action includes inhibiting pro -inflammatory cytokines.

  4. Chondroitin sources:

    a. Animal sources: chondroitin is usually obtained from the cartilage of cattle, pigs and sharks. Differences in sources can affect the quality and composition of chondroitin sulfate. Particular attention should be paid to the ethics and sustainability of sources, especially in the case of sharks.

    B. Synthetic sources: synthetic methods for the production of chondroitin are also developed, which avoids the use of animal sources. This is becoming more and more important for consumers who care about ethics and vegetarians.

B. What is glucosamine?

  1. Determination: glucosamine is an aminosahar, which is naturally produced in the body. It is a key component of glycosaminoglycans and hyaluronic acid, which are necessary for the construction and maintenance of cartilage tissue and synovial fluid (joint lubrication).

  2. Chemical structure: glucosamine is a modified glucose molecule, in which one of the hydroxyl groups is replaced by an amino group. Usually it is found in the form of two salts: glucosamine sulfate and hydrochloride glucosamine.

  3. Functions in the body:

    a. Synthesis of cartilage and synovial fluid: glucosamine is a building block for the synthesis of gags and hyaluronic acid. This is necessary to maintain a healthy structure of cartilage and ensure sufficient lubrication of the joints.

    B. Support for the metabolism of the cartilage: glucosamine can stimulate chondrocytes (cartilage cells) to the production of new components of cartilage tissue.

    C. Anti -inflammatory effect: glucosamine, like chondroitin, has some anti -inflammatory effect, albeit less pronounced.

  4. Sources of glucosamine:

    a. Rakoma shells: the most common source of glucosamine is crustacean shells such as shrimp, crabs and lobsters. This source can cause allergic reactions in people with allergies to seafood.

    B. Corn fermentation: an alternative source of glucosamine – cornation of corn. This method is suitable for vegetarians and people with allergies for seafood. It also allows you to control the quality and purity of the product.

    C. Synthetic glucosamine: synthetic glucosamine is also available, but it is less common than glucosamine obtained from crustaceans or corn.

C. The combination of chondroitin and glucosamine:

  1. Synergic effect: it is believed that the combination of chondroitin and glucosamine can have a synergistic effect, that is, their joint effect is more effective than each of them separately.

  2. The mechanism of action: glucosamine provides building blocks to restore cartilage, and chondroitin helps to protect the existing cartilage and reduce inflammation. Together they can help improve joint health.

  3. Confirming studies: Some studies show that the combination of chondroitin and glucosamine can be more effective in reducing pain and improving joint function than each of these components separately. However, research results are often contradictory.

II. The use of chondroitin and glucosamine:

A. Main indications:

  1. Osteoarthritis: The most common indication for the use of chondroitin and glucosamine is osteoarthritis, chronic degenerative joint disease, characterized by the destruction of cartilage.

  2. Other joint diseases: chondroitin and glucosamine can be used to alleviate the symptoms of other joint diseases, such as rheumatoid arthritis (as an auxiliary agent, but not the main treatment), as well as in joint injuries to accelerate recovery.

  3. Prevention: some people take chondroitin and glucosamine as a preventive measure to maintain joint health, especially athletes and people subject to high joint loads.

B. Clinical research:

  1. Research results: The results of clinical studies of chondroitin and glucosamine in osteoarthritis are ambiguous. Some studies show a significant improvement in symptoms, while others do not reveal a significant difference compared to placebo.

  2. Large studies (Gait, Moves): a major study by Gait (Glucosamine/Chondroitin Arthritis International Trial) showed that a combination of glucose and chondroitin can be effective for the subgroup of patients with moderate and severe knee pain. The study of MOves (MultICentre Osteoarthritis International Study) compared chondroitin sulfate with Diclofenac (NSAID) and found that chondroitin sulfate was not inferior to diclofenaca in a decrease in pain in ostearthritis of the knee joint.

  3. Met-analyzes: meta analyzes that combine the results of several studies also give conflicting results. Some meta-analyzes maintain the effectiveness of chondroitin and glucosamine, while others question it. It is important to consider the methodology and quality of research included in meta analysis.

  4. Factors affecting the results:

    a. The severity of the disease: the effectiveness of chondroitin and glucosamine may depend on the severity of osteoarthritis. They can be more effective in the early stages of the disease.

    B. Individual features: a reaction to chondroitin and glucosamine can vary in different people. Genetic factors and lifestyle can play a role.

    C. Product quality: The quality and composition of dietary supplements can vary significantly, which affects their effectiveness. It is important to choose products from reliable manufacturers who have undergone independent testing.

C. Recommendations for use:

  1. Dosage: The recommended dose of glucoseam is usually 1,500 mg per day, and chondroitin – 1200 mg per day. These doses are often divided into several techniques during the day.

  2. Duration of administration: to assess the effectiveness of chondroitin and glucoseamine, several months of administration are usually required. It is recommended to take them within 2-3 months to evaluate if there is an improvement in symptoms.

  3. How to take: dietary supplements with chondroitin and glucosamine are taken inside, drinking enough water.

  4. Combination with other treatment methods: chondroitin and glucosamine can be used in combination with other methods of treatment of osteoarthritis, such as physiotherapy, physiotherapy exercises, painkillers and anti -inflammatory drugs.

D. Contraindications and side effects:

  1. Contraindications:

    a. Allergies: seafood allergies (for glucosamine obtained from crustaceans).

    B. Pregnancy and breastfeeding: there is not enough data on the safety of the use of chondroitin and glucosamine during pregnancy and breastfeeding.

    C. Children’s age: It is not recommended to use in children without consulting a doctor.

    D. Blood coagulation disorders: chondroitin can affect blood coagulation, so it should be used with caution to people with coagulation disorders or taking anticoagulants.

  2. Side effects:

    a. Light side effects: the most common side effects of chondroitin and glucosamine are disorders of the gastrointestinal tract, such as nausea, diarrhea, constipation and bloating.

    B. Rare side effects: allergic reactions, headaches and skin rashes can rarely occur.

  3. Interaction with drugs: chondroitin can enhance the effect of anticoagulants such as warfarin. Caution must be observed while taking these drugs and control blood coagulation. Glucosamine can affect blood sugar, so people with diabetes should control the sugar level more carefully.
