Part 1: Glucosamine and Chondroitin – the basis of healthy joints
1.1 What is glucosamine?
Glucosamine is an aminosaccharide naturally produced in the human body. It is a key component of cartilage, which provides depreciation and flexibility of the joints. Glucosamine serves as a building block for glycosaminoglycans (GAG), which, in turn, make up the main structure of the cartilage.
1.1.1 glucosamine mechanism:
- GAG synthesis stimulation: Glucosamine provides the body with the necessary “raw materials” for the production of GAG, thereby maintaining the renewal and restoration of cartilage.
- Reducing inflammation: Glucosamine has anti -inflammatory properties, helping to reduce pain and edema in the joints. It inhibits enzymes involved in inflammatory processes, such as cyclooxygenase-2 (COO-2).
- Carriage protection from destruction: Glucosamine helps to strengthen the cartilage and protects it from degradation caused by enzymes, such as matrix metal proproteinase (MMP).
1.1.2 Glucosamine forms:
There are various forms of glucosamine used in dietary supplements:
- Glucosamine sulfate: The most studied form of glucosamine, which demonstrated effectiveness in clinical trials. It is believed that a sulfate group plays an important role in the metabolism of cartilage.
- Glucosamine hydrochloride: It has a higher concentration of glucosamine per gram compared to sulfate, but its effectiveness is less proven. Some studies show that it can be less effective than glucosamine sulfate.
- N-acetylhlucosamine: The precursor of hyaluronic acid, an important component of the synovial fluid that lubricates the joints. It can be useful for maintaining the health of the skin and intestines.
1.2 What is chondroitin?
Chondroitin Sulfate is another important component of cartilage, belonging to the class of glycosaminoglycans. It provides the cartilage of elasticity and the ability to retain water, which is necessary for depreciation and joint protection.
1.2.1 The mechanism of action of chondroitin:
- Holding water in cartilage: Chondroitin is a hygroscopic substance, that is, it has the ability to attract and hold water. This provides the cartilage with the necessary hydration and elasticity.
- Stimulation of the synthesis of cartilage tissue: Chondroitin, like glucosamine, stimulates the synthesis of Gag and collagen, the main components of the cartilage.
- Inhibition of enzymes that destroy the cartilage: Chondroitin inhibits the activity of enzymes, such as MMP, which destroy cartilage tissue in osteoarthritis and other degenerative joint diseases.
- Anti -inflammatory action: Chondroitin has anti -inflammatory properties, reducing pain and edema in the joints.
1.2.2 sources of chondroitin:
Chondroitin sulfate in dietary supplements is usually obtained from cartilage animals such as cattle, pigs and sharks. It is important to choose dietary supplements with chondroitin from reliable manufacturers to guarantee the quality and safety of the product.
1.3 Synergetic effect of glucosamine and chondroitin:
The combination of glucosamine and chondroitin is often used in dietary supplements for joints, since it is believed that they have a synergistic effect, enhancing the effect of each other. Glucosamine provides the body with building carts for cartilage, and chondroitin helps to retain water and protects the cartilage from destruction. Clinical studies, although with conflicting results, show that a combination of glucosamine and chondroitin can be more effective than each of these components separately, especially with moderate and strong osteoarthritis.
1.4 Dosage and application:
The recommended dosage of glucosamine is usually 1,500 mg per day, and chondroitin – 1200 mg per day. These doses are usually divided into several techniques during the day. The duration of admission can vary, but it is usually recommended to take dietary supplements with glucosamine and chondroitin for several months to evaluate their effectiveness. It is important to consult a doctor or other qualified specialist in the field of health care before starting to take any dietary supplements, especially if you have any existing diseases or you take any medicine.
1.5 side effects and contraindications:
Glucosamine and chondroitin are usually well tolerated, but in some cases side effects can occur, such as:
- Gastrointestinal disorders: Nausea, diarrhea, constipation, bloating.
- Allergic reactions: Skin rash, itching, urticaria.
- Headache.
Contraindications to the use of glucosamine and chondroitin:
- Seafood allergies (for glucosamine obtained from crustaceans).
- Pregnancy and breastfeeding.
- Reception of anticoagulants (care is necessary).
- Diabetes mellitus (blood sugar is required).

- People with joint injuries: Glucosamine and chondroitin can help accelerate recovery after joint injuries, such as ligaments and dislocations.
Part 5: Alternative methods of treating joint pain
In addition to the dietary supplements with glucosamine and chondroitin, there are other methods of treating joint pain:
- Physiotherapy: Physiotherapy can help strengthen the muscles around the joints, improve their mobility and reduce pain.
- Exercise: Regular exercises, such as walking, swimming and cycling, can help improve joint health and reduce pain.
- Weight loss: Weight reduction can reduce the load on the joints and reduce the pain.
- Anesthetic drugs: Anesthetic drugs, such as paracetamol and ibuprofen, can help reduce joint pain.
- Nonsteroidal anti -inflammatory drugs (NSAIDs): NSAIDs, such as Diclofenac and Narksen, can help reduce pain and inflammation in the joints.
- Corticosteroids: Corticosteroids can be used to reduce inflammation in the joints, but they have a number of side effects and should not be used for a long time.
- Hyaluronic acid injections: Injections of hyaluronic acid can help lubricate the joints and reduce the pain.
- Surgical intervention: In some cases, surgical intervention may be required to treat joint pain, for example, joint endoprosthetics.
Part 6: The importance of consulting a doctor
Before starting to take any dietary supplements with glucosamine and chondroitin or use other methods of treating joint pain, it is important to consult a doctor. The doctor can help determine the cause of pain in the joints and prescribe the most suitable treatment. He can also evaluate your individual risks and advantages from taking dietary supplements and other treatment methods. Self -medication can be dangerous and lead to undesirable consequences.

8.2 Recommendations for use for athletes:
Athletes are recommended to take glucosamine and chondroitin for preventive purposes, especially when classes in sports with a high load on joints, such as running, jumping, heavy athletics and martial arts. The dosage for athletes can be the same as for people with osteoarthritis: 1,500 mg of glucosamine and 1200 mg of chondroitin per day, divided into several tricks. It is important to consult a doctor or sports nutritionist in order to determine the optimal dosage and duration of the reception.
Part 9: Studies of glucosamine and chondroitin – a modern look
The effectiveness of glucosamine and chondroitin for the treatment of osteoarthritis is the subject of numerous studies. The research results are contradictory, and some studies show that these additives are no more effective than placebo. However, other studies show that glucosamine and chondroitin can help reduce pain and improve joint mobility, especially with moderate and strong osteoarthritis.
9.1 Key research:
- GAIT (Glucosamine/Chondroitin Arthritis Intervention Trial): A major study conducted by the US National Institute of Health showed that glucosamine and chondroitin are no more effective than placebo, for treating joint pain in osteoarthritis. However, in the subgroup of patients with moderate and strong osteoarthritis, a combination of glucosamine and chondroitin was more effective than a placebo.
