Dietrs for the joints: what doctors say

Dietrs for the joints: what doctors say

Section 1: Anatomy and joint physiology: the basis of understanding of the need for dietary supplements

Joints, complex bone joints, are the cornerstone of motor activity. Their structure and function are closely connected, determining the range of movements and stability. Before considering the role of biologically active additives (dietary supplements) in maintaining the health of the joints, it is necessary to deeply understand their anatomical structure and physiological processes.

1.1. Joint components:

• Joint cartilage: This smooth, elastic layer covering the ends of the bones provides slipping and cushioning. It consists mainly of chondrocytes (cartilage cells) and extracellular matrix, rich in type II collagen, proteoglycans (especially aggracan) and water. The cartilage does not contain blood vessels and nerves, so its nutrition is carried out due to the synovial fluid.
• Synovial shell: This membrane lines the inner surface of the joint capsule. It secrees synovial fluid, which lubricates the cartilage, provides its nutrition and removes metabolism products.
• Synovial fluid: A viscous, transparent fluid containing hyaluronic acid, providing its lubricating properties. It also contains nutrients and growth factors necessary to maintain the health of the cartilage.
• The joint capsule: A dense, fibrous shell surrounding the joint and providing its stability. It consists of an outer fibrous layer and inner synovial layer.
• Blues: Durable strips of connective tissue connecting the bones and provide additional stability of the joint.
• Meniski (in the knee joint): The cartilaginous discs located between the femoral and tibia bones, which improve the congruence of the articular surfaces, distribute the load and amortize the blows.
• Joint muscles and tendons: Provide movement in the joint and support its stability.

1.2. Physiological processes in the joint:

• Lubrication: The synovial fluid provides smooth sliding of the joint surfaces, reducing friction and wear of the cartilage.
• Depreciation: The articular cartilage and meniscus (in the knee joint) absorb strokes and distribute the load, preventing bone damage.
• Carthing power: The synovial fluid brings nutrients to chondrocytes necessary to maintain the structure and function of the cartilage.
• Removing waste: The synovial fluid removes metabolism products from cartilage, preventing their accumulation and damage.
• Synthesis and destruction of cartilage: Chondrocytes constantly synthesize and destroy the components of the extracellular matrix cartilage. In a healthy joint, these processes are in equilibrium.

1.3. Factors affecting the health of the joints:

• Age: With age, a natural decrease in the synthesis of collagen and proteoglycans occurs, which leads to thinning and weakening of cartilage.
• Injuries: Damage to the joint, such as ligaments, dislocations and fractures, can lead to the development of osteoarthritis.
• Overweight: The increased load on the joints, especially the knee and hip, contributes to their wear and damage.
• Insufficient physical activity: The lack of movement leads to weakening of the muscles that support the joints and the deterioration of the nutrition of cartilage.
• Excessive physical activity: Repeated movements or intensive training can lead to overload of the joints and their damage.
• Genetic predisposition: Some people have a genetic predisposition to the development of osteoarthritis.
• Inflammatory diseases: Rheumatoid arthritis and other inflammatory diseases can lead to damage to the joints.
• Inal meals: The feed of nutrients necessary for the synthesis of collagen and proteoglycans can adversely affect the health of the cartilage.

Section 2: The main dietary supplements for the joints and the mechanism of their action (from the point of view of evidence -based medicine)

The market for the joints is huge and diverse, offering a wide range of products that promise pain relief, restoration of cartilage and improvement of mobility. However, before proceeding with any additives, it must be understood that their effectiveness and safety are not always confirmed by strict clinical research. It is important to critically evaluate the information and consult a doctor.

2.1. Glucosamine and chondroitin:

• The mechanism of action (theoretical): Glucosamine is a construction block of glycosaminoglycans, which are part of the proteoglycans of cartilage. It is assumed that glucosamine stimulates the synthesis of proteoglycans and hyaluronic acid, thereby contributing to the restoration of cartilage and improving its amortization properties. Chondroitin sulfate is also a cartilage component and is supposed to inhibit enzymes that destroy cartilage and stimulates the synthesis of proteoglycans.
• Evidence base: The results of clinical studies are contradictory. Some studies show a slight improvement in symptoms (pain and mobility) in patients with osteoarthritis, especially the knee joint, while other studies have not revealed a significant difference compared to placebo. Met-analyzes of large studies also demonstrate ambiguous results. Some meta analyzes show a small, but statistically significant improvement, while others find no benefit.
• Important comments: The quality of dietary supplements with glucosamine and chondroitin can vary. It is important to choose products from reliable manufacturers who have undergone independent certification. The effect of taking may not be individual and does not appear immediately (it takes several months).
• Contraindications and side effects: Glucosamine and chondroitin are usually tolerated, but some people can cause side effects, such as nausea, heartburn, diarrhea or constipation. People with allergies to mollusks should avoid taking glucosamine obtained from shells of mollusks. Patients taking anticoagulants (for example, warfarin) should consult a doctor before taking chondroitin, as he can enhance the effect of anticoagulants.

2.2. Hyaluronic acid:

• The mechanism of action (theoretical): Hyaluronic acid is the main component of the synovial fluid, providing its viscosity and lubricating properties. The oral intake of hyaluronic acid can help improve joint lubrication and decrease friction. Injections of hyaluronic acid directly into the joint (intra -articular injections) are used to treat osteoarthritis, especially the knee joint.
• Evidence base: Studies of the oral -rhythmic acid oral acid administration for the treatment of osteoarthritis are limited. Some studies show a slight improvement in symptoms, while others have not revealed a significant difference compared to placebo. Intra -articular injections of hyaluronic acid showed moderate effectiveness in decreasing pain and improving mobility in patients with osteoarthritis of the knee joint. However, the effect of injections is temporary (usually lasts several months).
• Important comments: The quality of hyaluronic acid in dietary supplements can vary. It is important to choose products with high molecular weight of hyaluronic acid, since they are supposed to be better absorbed and have a more pronounced effect.
• Contraindications and side effects: The oral intake of hyaluronic acid is usually well tolerated. Intra -articular injections can cause local reactions, such as pain, edema and redness at the injection site.

2.3. Collagen:

• The mechanism of action (theoretical): Collagen is the main structural protein of cartilage, bones and ligaments. The oral intake of collagen, especially hydrolyzed collagen, can contribute to stimulating the synthesis of collagen in cartilage and improve its strength and elasticity.
• Evidence base: Some studies show that the oral intake of collagen can reduce joint pain and improve mobility in patients with osteoarthritis. However, most studies are small in sample size and need to confirm in larger, well -planned studies. Various types of collagen (for example, type I collagen, type II collagen) can have different effects on the joints.
• Important comments: It is important to choose a hydrolyzed collagen, since it is easier to absorb by the body.
• Contraindications and side effects: Collagen, as a rule, is well tolerated, but in some people side effects can cause side effects, such as nausea, diarrhea or allergic reactions.

2.4. Methyl sulfonylmetatan (MSM):

• The mechanism of action (theoretical): MSM is an organic compound of sulfur, which is present in the human body and plays an important role in the formation of connective tissue. It is assumed that MSM has anti -inflammatory and antioxidant properties that can help reduce pain and inflammation in the joints.
• Evidence base: Some studies show that MSM can reduce pain and improve joint function in patients with osteoarthritis. However, most studies are small in sample size and need to confirm in larger, well -planned studies.
• Important comments: MSM is often combined with glucosamine and chondroitin in dietary supplements for joints.
• Contraindications and side effects: MSM, as a rule, is well tolerated, but some people can cause side effects, such as nausea, diarrhea or headache.

2.5. Curcumin:

• The mechanism of action (theoretical): Kurkumin is an active component of turmeric, with pronounced anti -inflammatory and antioxidant properties. It is assumed that Kurkumin can inhibit inflammatory cytokines and enzymes that destroy cartilage, thereby reducing pain and joint inflammation.
• Evidence base: Some studies show that curcumin can be effective in reducing pain and improving joint function in patients with osteoarthritis. However, the bioavailability of curcumin (the body’s ability to absorb and use it) is low. To improve the bioavailability of curcumin, it is often combined with piperin (black pepper extract) or using liposomal forms of turmeric.
• Important comments: It is important to choose carcumin additives containing pipin or liposomal shape to improve its bioavailability.
• Contraindications and side effects: Kurkumin, as a rule, is well tolerated, but some people can cause side effects, such as nausea, diarrhea or allergic reactions. Kurkumin can interact with some drugs such as anticoagulants.

2.6. Omega-3 fatty acids:

• The mechanism of action (theoretical): Omega-3 fatty acids, such as eicopascentaenic acid (EPK) and dairyxaenic acid (DGC), have anti-inflammatory properties. It is assumed that they can reduce inflammation in the joints and relieve pain in patients with osteoarthritis and rheumatoid arthritis.
• Evidence base: Some studies show that omega-3 fatty acids can reduce joint pain, stiffness and need for non-steroidal anti-inflammatory drugs (NSAIDs) in patients with rheumatoid arthritis. Data on the effectiveness of omega-3 fatty acids with osteoarthritis is less convincing.
• Important comments: It is important to choose the supplements of omega-3 fatty acids containing a sufficient amount of EPC and DGK.
• Contraindications and side effects: Omega-3 fatty acids, as a rule, are well tolerated, but some people can cause side effects, such as nausea, belching or diarrhea. Omega-3 fatty acids can interact with anticoagulants.

2.7. S-adenosylmetionine (SAME):

• The mechanism of action (theoretical): Same is a natural compound that is involved in many biochemical reactions in the body, including cartilage synthesis and inflammation modulation. It is assumed that SAME can reduce pain and improve joint function in patients with osteoarthritis.
• Evidence base: Some studies show that Same can be as effective as NSAIDs in a decrease in pain in osteoarthritis. However, most studies are small in sampling.
• Important comments: Same can interact with some drugs such as antidepressants.
• Contraindications and side effects: Same can cause side effects, such as nausea, diarrhea or headache. Same is not recommended for people with bipolar disorder.

Section 3: The role of dietary supplements in a complex approach to the treatment of joint diseases

It is important to emphasize that dietary supplements for joints are not a replacement for traditional treatment, but rather complement it. A comprehensive approach to the treatment of joint diseases includes:

• Diagnosis: A thorough diagnosis to determine the cause of pain and inflammation in the joints. This may include examination, history of anamnesis, radiography, MRI and laboratory tests.
• Medication: The use of drugs, such as NSAIDs, analgesics, corticosteroids (in some cases) and disease-modifying anti-perise drugs (BMPP) for rheumatoid arthritis.
• Physiotherapy and physiotherapy exercises (exercise therapy): Exercises for strengthening muscles that support joints, improve mobility and reduce pain. Physiotherapeutic procedures, such as ultrasound, electrophoresis and magnetotherapy, can also be useful.
• Life change change: Reducing weight (with overweight), proper nutrition, avoiding joint overload and regular physical activity.
• Auxiliary means: The use of orthosis, bandages and canes to support joints and reduce the load on them.
• Surgical treatment: In severe cases, when conservative methods of treatment are ineffective, surgical intervention, such as joint endoprosthetics, may be required.

Within the framework of the integrated approach, dietary supplements can be used for:

• Relief symptoms: Some dietary supplements, such as glucosamine, chondroitin, MSM and curcumin, can help reduce pain and joint inflammation.
• Maintaining the health of the cartilage: Collagen and hyaluronic acid can contribute to maintaining the structure and function of cartilage.
• Improvements of mobility: Physiotherapy and exercise therapy in combination with dietary supplements can help improve joint mobility.

However, it is important to remember the following moments:

• Individual approach: The choice of dietary supplements should be individual and based on specific needs and characteristics of the patient.
• Consultation with a doctor: Before taking any dietary supplements, it is necessary to consult a doctor in order to make sure their safety and the absence of contraindications.
• Evaluation of effectiveness: It is important to evaluate the effectiveness of the intake of dietary supplements and, if necessary, adjust the dosage or change the drug.
• Do not expect a miracle: Bades are not panacea and cannot completely cure joint diseases. They can only help relieve symptoms and maintain joint health as part of a comprehensive approach to treatment.
• The importance of a balanced diet: Balanced diet, rich in nutrients necessary for joint health, plays an important role.
