Collagen: an extensive comparison of popular dietary supplements for beauty and health
1. Fundamentals of collagen: structure, types and role in the body
Collagen is a fibrillar protein, which is the main structural component of connective tissue in the human body and animals. It provides strength, elasticity and support of the skin, bones, cartilage, tendons, ligaments, blood vessels and other organs. In fact, collagen is about 30% of the total mass of protein in our body.
1.1. Collagen structure:
The collagen molecule has a characteristic triple spiral structure consisting of three polypeptide chains, each of which contains about 1000 amino acid residues. These chains are rich in glycine, proline and hydroxyproline (or hydroxylizine). A unique sequence of amino acids and triple spiral configuration give collagen exceptional tensile strength.
1.2. Types of collagen:
There are at least 28 different types of collagen, each of which has a unique structure and functions. However, the most common and studied types are:
- Type and: The most common type of collagen is about 90% of the total collagen in the body. Contained in the skin, bones, tendons, ligaments, teeth and other tissues. It provides the strength and elasticity of these structures. Loss of type I collagen with age is the main cause of wrinkles and a decrease in skin elasticity.
- Type II: The main component of cartilage, especially hyaline cartilage, which covers the articular surfaces of the bones. It provides resistance to compression and depreciation in the joints. Type collagen degeneration plays an important role in the development of osteoarthritis.
- Type III: Contained in the skin, vessels and internal organs. He plays an important role in maintaining the elasticity and strength of these tissues. Often found with a type I collagen.
- Type IV: The main component of basal membranes, thin layers of connective tissue supporting cells and organs. It provides structural support and filtering.
- Type V: Contained in the cornea of the eye, skin, hair and placenta. He plays a role in the formation of collagen fibrils of other types.
1.3. The role of collagen in the body:
Collagen functions are diverse and important for maintaining health and youth:
- Skin support: Collagen provides elasticity, elasticity and moisture of the skin. It prevents the formation of wrinkles, promotes wound healing and reduces the manifestation of cellulite.
- Joint health: Collagen is the main component of cartilage, ensuring its strength and depreciation. It helps reduce joint pain, improve their mobility and prevent the development of osteoarthritis.
- Bone strength: Collagen forms the basis of bone tissue, ensuring its strength and flexibility. It helps prevent osteoporosis and reduce the risk of fractures.
- Hair and nail health: Collagen strengthens the hair and nails, making it more durable and resistant to damage. It also contributes to the growth of hair and nails.
- Muscle support: Collagen is part of the connective tissue surrounding muscle fibers. It helps to restore muscles after training and prevents injuries.
- Vascular health: Collagen strengthens the walls of blood vessels, supporting their elasticity and preventing the formation of atherosclerotic plaques.
- Wound healing: Collagen plays an important role in the healing process of wounds, stimulating the formation of new tissue and closing the defect.
1.4. Factors affecting the synthesis of collagen:
With age, the synthesis of collagen in the body decreases, which leads to a deterioration in the condition of the skin, joints and other tissues. The synthesis of collagen is influenced by various factors, including:
- Age: With age, the activity of cells responsible for the synthesis of collagen (fibroblasts) is reduced.
- Genetics: A genetic predisposition can affect the rate of collagen synthesis and a predisposition to certain diseases associated with collagen deficiency.
- Ultraviolet radiation: UV radiation damages collagen fibers and reduces collagen synthesis.
- Smoking: Smoking reduces collagen synthesis and worsens the blood supply to the skin.
- Inal meals: The lack of nutrients necessary for the synthesis of collagen, such as vitamin C, Proilin and glycine, can lead to its deficiency.
- Chronic stress: Chronic stress can reduce collagen synthesis.
- Some diseases: Some diseases, such as autoimmune diseases and genetic disorders, can affect collagen synthesis.
2. Types of collagen additives: sources and forms
Collagen additives are becoming more and more popular due to their potential benefits for the health of the skin, joints and other tissues. The market presents various types of collagen additives that differ in sources and forms.
2.1. Collagen sources:
- Bovine collagen: Received from cow skin, bones and cartilage. Contains mainly collagen I and III. It is one of the most common and affordable sources of collagen.
- Marine Collagen: Received from leather, bones and scales of fish. It contains mainly type I collagen. Sea collagen is often considered more bioavailable than bullish collagen, as it has a smaller size of molecules. It can also be preferable for people who avoid the use of animal products.
- Porcine collagen: Get from pork skin and bones. Contains mainly collagen I and III. It is similar in composition to a bullish collagen, but can be less popular due to religious or dietary restrictions.
- Chicken collagen (Chicken collagen): Get it from chicken cartilage. It contains mainly type II collagen. It is mainly used to maintain joint health.
- Plant «collagen» (Vegan Collagen Boosters): In fact, they do not contain collagen, since collagen is a protein of animal origin. Instead, they contain ingredients that stimulate collagen synthesis in the body, such as vitamin C, amino acids and other nutrients. The effectiveness of these additives can be lower than that of additives containing animal collagen.
2.2. Forms of collagen additives:
- Collagen peptides (Hydrolyzed Collagen): Collagen, split into smaller fragments (peptides) through hydrolysis. This makes it more easily digestible and bioavailable for the body. Collagen peptides are the most common form of collagen additives.
- Gelatin (gelatin): Partially hydrolyzed collagen. It has a larger size of molecules than collagen peptides, and can be less easily digestible. Gelatin is usually used in the food industry, for example, for the preparation of jelly and marmalade.
- Non-unauthorized type II collagen (UC-II): A specially processed type II collagen, which retains its triple spiral structure. It is assumed that it has an immunomodulating effect and can reduce inflammation in the joints.
- Capsules and tablets: A convenient form for admission, but may contain less collagen than powder.
- Powder: You can mix with water, juice, smoothie or other drinks. It usually contains a higher concentration of collagen than capsules and tablets.
- Liquid additives: They contain collagen in liquid form, often with the addition of other ingredients, such as vitamins and minerals.
- Bars and drinks: Collagen is added to ready -made bars and drinks. The content of collagen in these products can be different.

- Take collagen regularly: To achieve the best results, take collagen regularly for several months.
- Combine the reception of collagen with a healthy lifestyle: To improve the condition of the skin, joints and other fabrics, combine the reception of collagen with a healthy lifestyle, including a balanced diet, regular physical exercises and sufficient sleep.
9. Alternative ways to maintain collagen synthesis:
In addition to taking collagen additives, there are alternative ways to maintain collagen synthesis in the body:
- Balanced nutrition: Use foods rich in nutrients necessary for collagen synthesis, such as vitamin C, Praise, glycine and copper. Such products include citrus fruits, berries, green leafy vegetables, meat, fish, eggs and nuts.
- Colligen products: Include in your diet products containing collagen, such as bone broth, poultry skin and fish with bones.
- Sun protection: Avoid excessive exposure to ultraviolet radiation, which damages collagen fibers. Use a high SPF sunscreen and wear protective clothes.
- Refusal of smoking: Smoking reduces collagen synthesis and worsens the blood supply to the skin. Refusal of smoking will help preserve collagen in the skin and other tissues.
- Stress management: Chronic stress can reduce collagen synthesis. Practice relaxation techniques such as yoga, meditation or breathing exercises to reduce stress levels.
10. The future of collagen research:
Collagen studies continue to develop. In the future, the following achievements can be expected:
- Development of new types of collagen additives: Research is aimed at developing new types of collagen additives, which will be more effective and bio -access.
- Studying the influence of collagen on various diseases: Studies continue to study the effect of collagen on various diseases, such as osteoporosis, osteoarthritis, cardiovascular diseases and skin diseases.
- Development of new methods of stimulation of collagen synthesis: Studies are aimed at developing new methods of stimulating collagen synthesis in the body, such as genetic therapy and stem cells.
- Individualization of collagen therapy: In the future, one can expect individualization of collagen therapy, taking into account the genetic characteristics and needs of each person.
11. Special considerations: collagen for vegetarians and vegans.
As mentioned earlier, a real collagen is a protein of animal origin and, therefore, is not suitable for vegetarians and vegan. Nevertheless, there are strategies and products aimed at stimulating their own production of collagen in the body.
-
«Collagen booster» for vegans: These products contain a combination of vitamins, minerals and amino acids necessary for the synthesis of collagen. Key ingredients include:
- Vitamin C: Critically important for the formation of collagen. It can be found in citrus fruits, berries, kiwi and Bulgarian pepper.
- Proline: The amino acid necessary for the stability of the collagen structure. Contained in asparagus, mushrooms and legumes.
- Glycine: Another key amino acid. Contained in sesame seeds, spinach and pumpkin.
- Lysine: An important amino acid involved in the formation of transverse ties in collagen. Contained in legumes, lentils and cinema.
- Silicon: A mineral that helps strengthen bones and connective tissue, indirectly maintaining collagen synthesis. Contained in oats, cucumbers and green leafy vegetables.
- Zinc: It is important for protein synthesis and wound healing. Contained in nuts, seeds and whole grains.
-
Diet support: Vegetarians and vegans should focus on the consumption of various products rich in the above nutrients. Adding superfluid products, such as spirulina (a rich source of amino acids) and Asai berries (rich in antioxidants), can also be useful.
-
Plant alternatives gelatin: Gelatin, which is a partially hydrolyzed collagen, is often used as a thickener. Vegans can use alternatives such as agar-agar (from seaweed), carragan (also from seaweed) and pectin (from fruits).
-
Evaluation of the effectiveness of «boosters»: It is important to understand that the effectiveness of plant «collagen booster» can vary depending on the individual characteristics of the body and observing a balanced diet. Some studies show that they can be useful for maintaining the health of the skin and joints, but additional studies are needed to confirm their effectiveness compared to additives containing animal collagen.
