Bad for joints with chondroitin and glucosamine: Efficiency

Section 1: Anatomy and joint physiology: the key to understanding

Understanding the structure and functioning of the joints is necessary to assess the effectiveness of dietary supplements with chondroitin and glucosamine. Joints are complex structures that ensure the movement and depreciation of the load.

1.1. Joint components:

Joint cartilage: Smooth, elastic fabric covering the ends of the bones in the joint. It consists mainly of chondrocytes (cartilage cells) and intercellular substance (matrix). Role: provides gluing bones relative to each other, reduces friction and absorbs strokes. The cartilage has no blood vessels, so the nutrition occurs due to the synovial fluid.
Synovial fluid: A viscous fluid filling the joint cavity. Contains hyaluronic acid that provides lubrication and nutrition of cartilage. Role: reduces friction, nourishes cartilage, removes metabolic products.
The joint capsule: A dense, fibrous shell surrounding the joint. Holds the articular surfaces together and contains ligaments. Role: ensures the stability of the joint, limits movement.
Blues: Durable, elastic stripes of connective tissue connecting bones to each other. Role: strengthen the joint, prevent excessive movements.
Joint muscles: The muscles surrounding the joint provide its movement. Role: Provide movement, stabilize the joint.

1.2. Carthing power mechanisms:

Synovial fluid diffusion: The main method of nutrition of cartilage, especially for deep layers. Nutrients and oxygen come from synovial fluid by diffusion through the matrix cartilage.
Load and decompression: In case of load on the joint, the synovial fluid is squeezed out of the cartilage, and with decompression – it is absorbed back, providing an influx of nutrients. Therefore, movement and moderate physical activity are important for the health of cartilage.
Subchondral bone: Bone located directly under the cartilage. A little nutrition of cartilage can occur through it, especially in the area of damage.

1.3. Age -related changes and degenerative processes:

With age and under the influence of various factors (injuries, overweight, genetic predisposition), degenerative changes in the joints occur:

Reducing the synthesis of matrix cartilage: Chondrocytes lose the ability to produce a sufficient amount of collagen and proteoglycans, the main components of the cartoon of cartilage.
Degradation of Matrix cartilage: Enzymes, such as matrix metal -propriets (MMP), begin to destroy the matrix cartilage, leading to its thinning and loss of elasticity.
Cutting violation: The production of synovial fluid is reduced, its quality worsens, which leads to a violation of the cartilage.
Changes in the subchondral bone: Sklerosis of the subchondral bone develops, which disrupts its depreciation properties and worsens the nutrition of cartilage.
Osteofite education: Bone growths (osteophytes) are formed along the edges of the articular surfaces, which limit movement and cause pain.

These changes lead to the development of osteoarthritis (OA), the most common joint disease.

Section 2: Chondroitin and Glucosamine: What is it?

Chondroitin and glucosamine are natural compounds that are important components of cartilage.

2.1. Glucosamine:

Chemical structure: Aminosaccharide, a derivative of glucose.
Function in the body: It is the precursor of glycosaminoglycans (GAG), which, in turn, are part of proteoglycans – the main components of the cartoon of cartilage. It stimulates the synthesis of GAG and hyaluronic acid.
Sources: It is produced by the body. In dietary supplements, crustaceans are obtained from the shell (shrimp, crabs, lobsters) or synthetically (glucosamine hydrochloride).
Forms: Glucosamine sulfate, glucosamine hydrochloride, n-acetylhlucosamine.
- Glucosamine sulfate: The most studied form is often used in clinical studies. It is believed that a sulfate group plays a role in the metabolism of cartilage.
- Glucosamine hydrochloride: Less studied form. It can be more bio -access, but research is contradictory.
- N-acetylhlucosamine: The precursor of hyaluronic acid, an important component of the synovial fluid.

2.2. Chondroitin:

Chemical structure: Sulfate glycosaminoglican (GAG). It consists of repeated units of glucuronic acid and n-acetylgalactosamine.
Function in the body: It is part of the proteoglycans of the matrix cartilage. It attracts water into cartilage, ensuring its elasticity and depreciation properties. Inhibits enzymes that destroy cartilage (MMP).
Sources: It is produced by the body. In the dietary supplements, cattle, pigs or sharks are obtained from cartilage fabric.
Forms: Chondroitin sulfate a, chondroitin sulfate C. can vary in molecular weight and degree of sulfate.

2.3. Action mechanisms:

It is believed that chondroitin and glucosamine have the following effect on the joints:

Chondroprotective action: They protect the cartilage from destruction, stimulate the synthesis of the components of the cartoon of cartilage (collagen and proteoglycans).
Anti -inflammatory action: Reduce inflammation in the joint, reduce the activity of inflammatory mediators (cytokines).
Analgesic action: Reduce the pain in the joint, possibly by reducing inflammation and improving the joint function.
Improving joint lubrication: Glucosamine can contribute to the production of hyaluronic acid, which is the main component of synovial fluid.

2.4. Combined action:

It is assumed that the combined use of chondroitin and glucosamine has a synergistic effect, that is, enhances the effect of each other. Chondroitin and glucosamine affect different aspects of cartilage metabolism, so their joint use can be more effective than the use of each substance separately.

Section 3: Clinical Studies: evidence of effectiveness

The effectiveness of chondroitin and glucosamine in the treatment of osteoarthritis is the subject of numerous clinical studies, the results of which are ambiguous.

3.1. Key clinical research:

GAIT (Glucosamine/Chondroitin Arthritis Intervention Trial): A large multicenter study conducted in the United States. Compared the effectiveness of glucosamine, chondroitin, their combinations and placebo in the treatment of knee -based osteoarthrosis. Results: The combination of glucosamine and chondroitin showed a significant improvement in pain symptoms only in the subgroup of patients with moderate and severe pain.
MOVES (Multicenter Osteoarthritis interVEntion Study): A European study that compared the effectiveness of chondroitin sulfate and celloxib (NSAIDs) in the treatment of knee -control osteoarthritis. Results: Chondroitin Sulfate showed comparable efficiency with a celloxibe in reducing pain and improving the function of the joint.
LEGS (Long-term Evaluation of Glucosamine Sulfate): A long -term study that evaluated the effect of glucosamine sulfate on the progression of osteoarthrosis of the knee joint. Results: Glucosamine Sulfate slows down the narrowing of the joint gap compared to the placebo, which indicates a possible structural-modifying effect.
Numerous Meta-Analyses: Numerous meta analyzes (associations of the results of several studies) give conflicting results. Some meta-analyzes show that chondroitin and glucosamine can be effective in reducing pain and improving the joint function, while others do not confirm this effectiveness.

3.2. Factors affecting research results:

Differences in the results of clinical research can be associated with several factors:

Differences in research design: Differences in the criteria for the inclusion of patients, dosages of drugs, duration of treatment, methods for evaluating the results.
Differences as products: The content of chondroitin and glucosamine in dietary supplements can vary, and can also be pollution by other substances.
Individual characteristics of patients: Age, severity of osteoarthritis, concomitant diseases, genetic predisposition.
Using different forms: The use of various forms of glucosamine (sulfate, hydrochloride) and chondroitin (various degrees of sulfate and molecular weight) can affect the results.
Placebo effect: A significant effect of placebo in studies of osteoarthritis.

3.3. Conclusions from clinical research:

Evidence of the effectiveness of chondroitin and glucosamine in the treatment of osteoarthritis is ambiguous.
Some studies show that they can be effective in reducing pain and improving joint function, especially in patients with moderate and severe pain.
Glucosamine sulfate can have a structural-modifying effect, slowing the progression of osteoarthrosis.
Further research with a more stringent design and standardized products to confirm the effectiveness of chondroitin and glucosamine is needed.
