Part 1: Vitamin C: Fundamentals and biological role

1. What is vitamin C (ascorbic acid)?

Vitamin C, also known as ascorbic acid, is a water -soluble vitamin necessary for the normal functioning of the human body. It belongs to the group of organic compounds and plays a key role in many biochemical processes. The human body is not able to independently synthesize vitamin C, so it should come from outside, through food or additives. Vitamin C is a powerful antioxidant that protects the cells from damage to free radicals. It is also involved in the synthesis of collagen, strengthening the immune system and improving iron absorption.

2. Chemical structure and properties.

Vitamin C has a chemical formula C6H8O6. Its molecule contains six carbon atoms, eight hydrogen atoms and six oxygen atoms. Ascorbic acid exists in two main forms: l-acscorbic acid (restored form) and dehydroacorbic acid (oxidized form). Both forms have vitamin activity, but l-acscorbic acid is a more active and predominant form in the body. Vitamin C is acid, so its aqueous solutions have a sour taste. It easily oxidizes in the air, especially in an alkaline environment. Vitamin C is also sensitive to high temperatures and light, which can lead to its destruction during cooking products.

3. Sources of vitamin C: food and supplements.

The best source of vitamin C is food, especially fruits and vegetables. The richest sources include:

• Citrus: Oranges, lemons, grapefruit, lime.
• Berries: Strawberries, blueberries, raspberries, cranberries, currants.
• Vegetables: Bulgarian pepper (especially red and yellow), broccoli, Brussels cabbage, cauliflower, spinach, tomatoes.
• Other fruits: Kiwi, mango, papaya, guava.

Some products are enriched with vitamin C, for example, juices and flakes for breakfast.

Vitamin C additives are available in various forms:

• Ascorbic acid: The most common and affordable form.
• Sodium Ascorbat: buffering form, which gently affects the stomach.
• Calcium ascorbate: Another buffering form containing calcium.
• Liposomal vitamin C: It is enclosed in liposomes, which improves its assimilation.
• Vitamin C complexes with bioflavonoids: Bioflavonoids enhance vitamin C.

4. The recommended daily dose and factors affecting the need.

The recommended daily dose (RSD) of vitamin C varies depending on age, gender and health. For adults, RSD is about 75 mg for women and 90 mg for men. During pregnancy and breastfeeding, the need for vitamin C increases. Smoking also increases the need for vitamin C, since cigarette smoke contains free radicals that deplete vitamin C reserves in the body. Some diseases, such as infections, inflammatory diseases and injuries, can also increase the need for vitamin C.

5. The mechanisms of absorption and metabolism of vitamin C.

Vitamin C is absorbed in the small intestine. Highness occurs using two main mechanisms: active transport and passive diffusion. Active transport is the main mechanism for low concentrations of vitamin C in the intestines. It is carried out using sodium-dependent conveyor vitamin C (SVCT1). At high concentrations of vitamin C in the intestines, passive diffusion prevails. The absorption of vitamin C decreases with an increase in the dose. After absorption, vitamin C enters the bloodstream and is distributed through all tissues of the body. It accumulates in the greatest concentrations in the adrenal glands, brain and immune cells. Vitamin C is metabolized in the liver and excreted from the body in the urine.

6. The role of vitamin C as a powerful antioxidant.

Vitamin C is one of the most important antioxidants in the body. Antioxidants protect the cells from damage by free radicals. Free radicals are unstable molecules that can damage DNA, proteins and lipids, which leads to cellular aging and the development of various diseases, including cardiovascular diseases, cancer and arthritis. Vitamin C neutralizes free radicals, giving them its electrons, thereby stabilizing them and preventing cell damage. It also helps to restore other antioxidants, such as vitamin E.

7. Participation in collagen synthesis: key value for connective tissue.

Vitamin C plays an important role in the synthesis of collagen. Collagen is the main structural protein of connective tissue, which provides the strength and elasticity of the skin, bones, cartilage, tendons and blood vessels. Vitamin C is necessary for the work of enzymes that are involved in hydroxylating the proline and lysine, two amino acids that are necessary for the formation of a stable triple collagen spiral. Vitamin C deficiency leads to a violation of collagen synthesis, which can cause mourn, a disease characterized by weakness of connective tissue, bleeding gums and slow healing of wounds.

8. Vitamin C and immunity: strengthening the body’s body.

Vitamin C plays an important role in strengthening the immune system. It supports the function of various immune cells, including leukocytes, neutrophils and lymphocytes. Vitamin C stimulates the production of interferon, protein, which has antiviral activity. It also improves phagocytosis, a process in which immune cells absorb and destroy pathogens. Vitamin C deficiency weakens the immune system and increases susceptibility to infections.

9. Other important functions of vitamin C in the body.

In addition to antioxidant protection, collagen synthesis and immunity strengthening, vitamin C performs other important functions in the body:

• Iron assimilation: Vitamin C improves the absorption of a non -meter iron, which is found in plant products.
• Synthesis neurotransmitted: Vitamin C is necessary for the synthesis of some neurotransmitters, such as norepinephrine and dopamine, which play an important role in the brain.
• Protection against cardiovascular diseases: Vitamin C helps reduce blood cholesterol and prevents blood clots, which reduces the risk of developing cardiovascular diseases.
• Cancer Protection: Vitamin C has antioxidant properties that can help protect the cells from DNA damage, which reduces the risk of cancer.

10. Vitamin C deficiency: symptoms and consequences.

Vitamin C deficiency, also known as mourn, is a serious disease that occurs with a prolonged deficiency of vitamin C in the diet. Symptoms of sorrow include:

• Weakness and fatigue.
• Bleeding gums and teeth loss.
• Slow wound healing.
• Pain in the joints and muscles.
• Mild bleeding.
• Anemia.
• Weakening of the immune system.

In severe cases, mourn can lead to death. Vitamin C deficiency is more often found in people who adhere to a strict diet, abuse alcohol or smoke.

Part 2: Vitamin C and joints: Scientific data

1. Joint inflammation: the role of oxidative stress.

Joint inflammation is a common problem that can be caused by various factors, including autoimmune diseases (for example, rheumatoid arthritis), injuries, infections and age -related changes (for example, osteoarthritis). Inflammation is characterized by redness, edema, pain and restriction of joint mobility. Oxidative stress plays an important role in the development and progression of joint inflammation. Oxidative stress occurs when the balance between the formation of free radicals and antioxidant protection is disturbed in the body. Free radicals damage the joints of the joints, including cartilage cells (chondrocytes), which leads to inflammation and destruction of cartilage.

2. Vitamin C as an antioxidant: neutralization of free radicals in the joints.

Vitamin C, being a powerful antioxidant, is able to neutralize free radicals in the joints, thereby reducing oxidative stress and reducing inflammation. It protects chondrocytes from damage by free radicals, preventing their death and stimulating their regeneration. Vitamin C also helps to restore other antioxidants, such as vitamin E, which also play an important role in protecting the joints. Studies have shown that in people with inflammatory joint diseases, such as rheumatoid arthritis, a deficiency of vitamin C is often observed. An increase in vitamin C consumption can help reduce the level of inflammation and relieve symptoms of the disease.

3. The effect of vitamin C on the synthesis of collagen in cartilage.

As mentioned earlier, vitamin C is necessary for the synthesis of collagen, the main structural protein of cartilage tissue. The cartilage provides depreciation and smoothness of the joints. With osteoarthritis and other degenerative diseases of the joints, cartilage is destroyed, which leads to pain and limiting mobility. Vitamin C stimulates collagen synthesis with chondrocytes, thereby contributing to the restoration and maintenance of the integrity of cartilage. It also improves the quality of collagen, making it more durable and resistant to destruction.

4. Studies on the effect of vitamin C on osteoarthritis (osteoarthrosis).

Osteoarthritis is the most common joint disease characterized by cartilage degeneration. Studies show that vitamin C can play a role in the prevention and slowdown of osteoarthritis progression. Some studies have shown that people with high consumption of vitamin C have a lower risk of developing the osteoarthritis of the knee joint. Other studies have shown that taking vitamin C additives can help reduce pain and improve joint function in people with osteoarthritis. However, additional studies are needed to confirm these results and determine the optimal dose of vitamin C for the treatment of osteoarthritis.

5. Vitamin C and rheumatoid arthritis: relief of symptoms and slowdown in progression.

Rheumatoid arthritis is an autoimmune disease that causes joint inflammation and destruction of cartilage and bones. Studies have shown that vitamin C can help alleviate the symptoms of rheumatoid arthritis and slow down the progression of the disease. Vitamin C has anti-inflammatory properties and can help reduce the level of inflammatory markers in the blood, such as C-reactive protein (CRB) and the factor of Alpha tumor necrosis (FI-α). It also protects the joints from damage to free radicals and stimulates collagen synthesis. Some studies have shown that taking vitamin C additives can help reduce the pain, stiffness and swelling of the joints in people with rheumatoid arthritis.

6. Vitamin C and gout: decrease in uric acid level.

Gout is an inflammatory joint disease caused by the deposition of uric acid crystals in the joints. Vitamin C can help reduce the level of uric acid in the blood, thereby reducing the risk of gout developing and facilitating its symptoms. Studies have shown that vitamin C increases the excretion of uric acid in urine. It also has anti -inflammatory properties that can help reduce the pain and edema of the joints during gout attacks.

7. Vitamin C and other inflammatory joint diseases.

In addition to osteoarthritis, rheumatoid arthritis and gout, vitamin C can be useful for other inflammatory joint diseases, such as psoriatic arthritis, ankylosing spondylitis and reactive arthritis. These diseases are characterized by inflammation of the joints and tissue damage. Vitamin C, due to its antioxidant and anti -inflammatory properties, can help reduce inflammation, relieve symptoms and slow down the progression of these diseases.

8. Clinical trials and meta analyzes: confirmation of vitamin C efficiency for the joints.

Numerous clinical trials and meta analyzes were carried out to study the effect of vitamin C on the health of the joints. Some meta-analyzes have shown that taking vitamin C additives can help reduce pain and improve joint function in people with osteoarthritis. Other meta-analyzes showed that vitamin C can help reduce the level of inflammatory markers in the blood of people with rheumatoid arthritis. However, the results of the studies are often contradictory, and additional large -scale clinical trials are needed to confirm the effectiveness of vitamin C for the treatment of joint diseases and determine the optimal doses and duration of administration.

9. The influence of vitamin C on the prevention of the destruction of the cartilage.

Vitamin C plays an important role in preventing the destruction of cartilage. It protects chondrocytes from damage to free radicals and stimulates the synthesis of collagen, the main structural protein of cartilage tissue. It also inhibits the activity of enzymes that destroy the cartilage, such as metal proproteinase (MMP). Studies have shown that in people with high consumption of vitamin C the risk of cartilage destruction below.

10. Vitamin C and recovery after joint injuries.

Vitamin C can help accelerate recovery after joint injuries, such as ligaments, dislocations and fractures. It stimulates the synthesis of collagen, which is necessary to restore damaged tissues. It also has anti -inflammatory properties that can help reduce pain and edema after injury. Some studies have shown that taking vitamin C additives can help improve healing of bone fractures.

• Gout: To reduce the level of uric acid with gout, it may take up to 1,500 mg of vitamin C per day.

It is important to consult a doctor or nutritionist in order to determine the optimal dosage of vitamin C for your individual needs.

5. Vitamin C and collagen: the synergistic effect of joint health.

Vitamin C and collagen work synergistic to maintain joint health. Collagen is the main structural protein of cartilage, and vitamin C is necessary for its synthesis. Reception of collagen additives in combination with vitamin C can enhance the effect of cartilage restoration and reduce joint pain.

6. Vitamin C and glucosamine/chondroitin: complex support of cartilage.

Glucosamine and chondroitin are popular additives to maintain joint health. Glucosamine is a building block of cartilage, and chondroitin helps to retain water in cartilage. The combination of vitamin C with glucosamine and chondroitin can provide comprehensive support for cartilage tissue, contributing to its restoration and reduction of inflammation.

7. Vitamin C and other antioxidants: increased joint protection.

The combination of vitamin C with other antioxidants, such as vitamin E, selenium and coenzyme Q10, can enhance joint protection from damage by free radicals. These antioxidants work synergetically, neutralizing various types of free radicals and protecting the cells from oxidative stress.

8. Vitamin C and physical exercises: optimizing the restoration and joint protection.

Exercise is important to maintain joint health, but they can also lead to the formation of free radicals. The intake of vitamin C Before and after training can help protect the joints from damage to free radicals and accelerate the restoration after load.

9. Vitamin C and lifestyle: factors that affect the need and effectiveness.

Several lifestyle factors can affect the need and effectiveness of vitamin C:

• Smoking: Smoking increases the need for vitamin C, since cigarette smoke contains free radicals that deplete vitamin C reserves in the body.
• Alcohol: Alcohol abuse can violate the absorption of vitamin C.
• Stress: Chronic stress can increase the need for vitamin C.
• Diseases: Some diseases, such as infections, inflammatory diseases and injuries, can increase the need for vitamin C.

10. Possible side effects and contraindications when taking vitamin C.

Taking vitamin C in moderate doses is usually safe. However, high doses of vitamin C (more than 2000 mg per day) can cause side effects, such as:

• Diarrhea.
• Nausea.
• Stomach ache.
• Heartburn.
• Stones in the kidneys (at predisposed people).

Vitamin C can interact with some drugs such as anticoagulants and aspirin. People with kidney diseases or hemochromatosis should consult a doctor before taking the additives of vitamin C. Vitamin C can also affect the results of some laboratory tests.
