Dietary dietary supplements: comparison of compositions and efficiency
Section 1: Introduction to Chondroprotectors and their role in maintaining joint health
1.1. Joint cartilage: structure and functions. The articular cartilage, also known as hyaline cartilage, is a specialized connective tissue covering the articular surfaces of the bones. Its main function is to ensure smooth gling of bones relative to each other during movement, minimizing friction and shockproofing. Structurally cartilage consists of chondrocytes (cartilage cells), extracellular matrix, which includes collagen, proteoglycans (aggrakan) and water. Collagen provides tensile strength, and proteoglycans are responsible for the elasticity and ability of cartilage to hold water, which is critically important for its amortizing properties. Cartilage does not have blood vessels and nerves, therefore, chondrocytes are powered by diffusion from synovial fluid. This determines the slow regeneration of cartilage and its susceptibility to degenerative changes.
1.2. Degenerative joint diseases: osteoarthritis and others. Degenerative joint diseases, such as osteoarthritis (OA), are characterized by progressive destruction of the joint cartilage and changes in the subchondral bone (bone under cartilage). OA is the most common joint disease and the main cause of pain and disability in the elderly. Risk factors for the development of OA include age, genetic predisposition, joint injuries, obesity, repeated loads and some diseases, such as rheumatoid arthritis. Other degenerative diseases of the joints include chondroxation (softening of the cartilage), aseptic necrosis of the femoral head and other rare conditions. The pathogenesis of the OA includes a complex cascade of biochemical and mechanical events, leading to an imbalance between the synthesis and the destruction of cartilage components.
1.3. The role of chondroprotectors in the slowdown of the progression of joint diseases. Chondroprotectors are a group of substances that are supposed to have the ability to protect and restore articular cartilage, slowing down the progression of degenerative joint diseases. They include glucosamine, chondroitin sulfate, hyaluronic acid, methyl sulfonylomethane (MSM) and other compounds. The mechanisms of action of chondroprotectors are diverse and include stimulation of the synthesis of cartilaginous matrix (collagen and proteoglycans), inhibiting enzymes that destroy cartilage (matrix metal -propriets), a decrease in inflammation in the joint, improvement of cartilage hydration and stimulation of synthesis of synovial fluid. It is important to note that the effectiveness of chondroprotectors in the slowdown of the progression of joint diseases is the subject of active scientific research, and the research results are contradictory.
1.4. DOUDITION DEMPLE (biologically active additives) and their regulation. Biologically active additives (dietary supplements) are products designed to supplement the diet. They can contain vitamins, minerals, herbs, amino acids and other substances. Bades are not drugs and are not intended for the treatment, prevention or diagnosis of diseases. Bad regulation varies in different countries. In the United States, dietary supplements are regulated as food, and not as medicines, which means that FDA (management for sanitary supervision of the quality of food and medicines) does not require preliminary approval of dietary supplements before selling them. In Europe, the regulation of dietary supplements is more strict, and many countries require registration of dietary supplements before selling them. In Russia, the regulation of dietary supplements is carried out by Rospotrebnadzor. It is important to note that the quality and safety of dietary supplements can vary depending on the manufacturer, and consumers should carefully choose dietary supplements by buying them from reliable suppliers and paying attention to the composition and certification.
Section 2: The main components of dietary supplements for the joints and their action mechanisms
2.1. Glucosamine: forms, absorption and effect on chondrocytes. Glucosamine is aminosaccharide, which is a natural component of articular cartilage and synovial fluid. It plays a key role in the synthesis of glycosaminoglycans (GAG), the main building blocks of cartilage matrix. In dietary supplements, glucosamine is usually represented in two forms: glucosamine sulfate and glucosamine hydrochloride. Glucosamine sulfate is usually considered more effective than glucosamine hydrochloride, since it contains a sulfate group that is necessary for the synthesis of the Gag. The absorption of glucosamine after oral administration varies depending on the shape and individual characteristics of the body. Glucosamine sulfate, as a rule, is better absorbed than glucosamine hydrochloride. After absorption, glucosamine is transported to the articular cartilage, where it stimulates chondrocytes to the synthesis of collagen and proteoglycans, suppresses enzymes that destroy cartilage (matrix metal propriets) and reduces inflammation.
2.2. Chondroitin sulfate: varieties, bioavailability and anti -inflammatory properties. Chondroitin sulfate is glycosaminoglican, which is an important component of articular cartilage. It provides elasticity and elasticity of cartilage, holding water in the matrix. In dietary supplements, chondroitin sulfate is usually obtained from cartilage sharks, cattle or pigs. There are various varieties of chondroitin sulfate that differ in molecular weight and degree of sulfate. Chondroitin sulfate with lower molecular weight, as a rule, is better absorbed. The bioavailability of chondroitin sulfate after oral administration is relatively low, usually about 10-15%. Chondroitin sulfate has anti-inflammatory properties, suppressing the synthesis of pro-inflammatory cytokines and enzymes, such as cyclooxygenase-2 (COO-2) and induced No-syntase (Inos). It can also stimulate the synthesis of hyaluronic acid, which is an important component of synovial fluid.
2.3. MSM (methyl sulfonylmetatan): mechanisms of action and influence on pain and inflammation. Methyl sulfonylmetatan (MSM) is an organic compound of sulfur, which is naturally found in plants, animals and humans. MSM has antioxidant and anti -inflammatory properties. It is believed that MSM has a positive effect on the health of the joints, reducing pain and inflammation. MSM action mechanisms include the suppression of the synthesis of pro-inflammatory cytokines, such as Interlayykin-6 (IL-6) and the Alpha tumor necrosis factor (TNF-α), inhibiting the Activation of NF-X (Kappa-Bi nuclear factor), which plays a key role in the inflammatory process, and an increase in the level of glutathione, an important antioxidant. MSM can also improve the flexibility and mobility of the joints, reducing stiffness.
2.4. Hyaluronic acid: role in synovial fluid and the possibilities of oral use. Hyaluronic acid (Civil Code) is glycosaminoglican, which is the main component of the synovial fluid filling the joint cavity. The Civil Code provides lubrication of the joint surfaces, shockpacking of strokes and nutrition of cartilage. The viscosity and elasticity of the synovial fluid depend on the concentration and molecular weight of the Civil Code. In degenerative joint diseases, the concentration and molecular weight of the Civil Code in the synovial fluid are reduced, which leads to a deterioration in its properties. Civil Code can be introduced directly into the joint cavity in the form of injections to restore the viscosity of the synovial fluid and reduce pain. The oral use of the Civil Code can also be useful, although the bioavailability of the oral Civil Code is relatively low. It is believed that the oral Civil Code can stimulate the synthesis of the endogenous Civil Code in the joints and have an anti -inflammatory effect.
2.5. Collagen: types of collagen and their role in the structure of the articular cartilage. Peptides of collagen. Collagen is the main structural protein that forms the basis of connective tissues, including joint cartilage, bones, ligaments and tendons. There are many types of collagen, but the most important joints of the joints are collagen type II, type I collagen and type III collagen. Type II collagen is the main component of the articular cartilage, ensuring its tensile strength and stress resistance. Type I collagen is the main component of bones, ligaments and tendons. Type III collagen is also present in the joint cartilage and is involved in the process of its regeneration. Collagen peptides are short fragments of collagen obtained by hydrolysis (splitting) of collagen fibers. Collagen peptides have high bioavailability and can stimulate the synthesis of endogenous collagen in the joints, improving the structure and function of cartilage.
2.6. Vitamins and minerals: vitamin D, vitamin C, manganese, copper, zinc and their effect on joint health. Vitamins and minerals play an important role in maintaining joint health. Vitamin D is necessary to maintain the health of bones and muscles, as well as to regulate the immune system. Vitamin D deficiency can increase the risk of osteoarthritis and other joint diseases. Vitamin C is a powerful antioxidant that protects the articular cartilage from damage by free radicals. It is also necessary for collagen synthesis. Manganese, copper and zinc are trace elements that are involved in the synthesis of collagen and other components of the cartilage matrix. The deficiency of these trace elements can worsen the health of the joints.
2.7. Plant extracts: Boswellia, turmeric, ginger and their anti -inflammatory properties. Plant extracts, such as Boswellium, turmeric and ginger, have anti -inflammatory properties and can be useful to reduce pain and inflammation in the joints. Boswellia contains bosvelic acids that inhibit the 5-lipoxygenase enzyme, which is involved in the synthesis of leukotrienes, pro-inflammatory mediators. Turmeric contains turmeric, which has powerful antioxidant and anti -inflammatory properties. Kurkumin inhibits the activation of NF-κB and suppresses the synthesis of pro-inflammatory cytokines. Ginger contains ginerols that have anti -inflammatory and analgesic properties.
