Are dietary supplements safe with collagen: doctors’ opinion
Section 1: Collagen: Fundamentals and role in the body
-
1 What is collagen?
Collagen is the most common protein in the human body and animals. It forms the basis of connective tissue, providing the strength and elasticity of the skin, bones, joints, tendons, ligaments and blood vessels. Collagen can be represented as a frame that supports the structure of the body.
The collagen molecule consists of three polypeptide chains rolled into a spiral. These chains are rich in amino acids by glycine, a prolit and hydroxyproline, which give collagen a unique structure and properties.
-
2 Types of collagen and their functions
There are about 28 different types of collagen, but the most common and studied are the types of I, II, III, IV and V. Each type of collagen performs a certain function in the body:
- Type and: The most common type of collagen. It is found in the skin, bones, tendons, ligaments and teeth. Provides the strength and elasticity of tissues.
- Type II: The main component of cartilage fabric. Is responsible for the depreciation and flexibility of the joints.
- Type III: Contained in the skin, muscles and blood vessels. Supports elasticity and structure of organs.
- Type IV: The main component of basal membranes supporting cells and tissues.
- Type V: Contained in cell membranes and placenta. Plays an important role in the formation of fabrics.
-
3 Collagen synthesis in the body
Collagen synthesis is a complex process that occurs inside the cells called fibroblasts (in the skin, tendons and ligaments), chondrocytes (in cartilage) and osteoblasts (in bones). This process includes several stages:
- Transcription and broadcast: Information about the sequence of collagen amino acids is read from DNA and transferred to RNA. RNA is then used to synthesize polypeptide collagen circuits.
- Hydroxylating: The amino acids Proin and the lysine are hydroxylated using enzymes that depend on vitamin C. This process is important for the stability of the structure of collagen.
- Glycosylation: Sugar molecules (glucose or galactose) join some hydroxylizine molecules.
- The formation of a triple spiral: Three polypeptide chains turn into a characteristic triple collagen spiral.
- Secretion: The Precollagen molecule (collagen predecessor) is secreted from the cage.
- Transformation to collagen: Outside the cage, the prollagen turns into a collagen by delaying the end peptides.
- Sewing: Collagen molecules are sewn together, forming strong collagen fibers.
The synthesis of collagen is influenced by various factors, including age, genetics, nutrition and environmental effects. With age, collagen synthesis slows down, which leads to a decrease in skin elasticity, wrinkles and joint problems.
-
4 Factors affecting the level of collagen
The level of collagen in the body can decrease under the influence of the following factors:
- Age: With age, collagen synthesis naturally slows down.
- Genetics: Some people are genetically predisposed to a more rapid decrease in collagen levels.
- Nutrition: The deficiency of vitamin C, blank, glycine and other nutrients necessary for the synthesis of collagen can lead to a decrease in its level.
- The effect of ultraviolet radiation: Ultraviolet radiation damages collagen fibers in the skin, which leads to photo glass.
- Smoking: Smoking reduces collagen synthesis and worsens the blood supply to the skin.
- Stress: Chronic stress can negatively affect the synthesis of collagen.
- Autoimmune diseases: Some autoimmune diseases can cause collagen destruction.
Section 2: Bades with collagen: types and sources
-
1 Varieties of collagen additives
There are several types of collagen additives on the market, differing in shape, source and processing method:
- Hydrolyzed collagen (collagen peptides): This is the most common form of collagen in addition. Hydroization is the process of splitting collagen molecules into smaller peptides, which facilitates their absorption by the body.
- Non-unauthorized collagen type II (UC-II): This type of collagen retains its natural structure. It is assumed that it works by modulating the immune system and reducing inflammation in the joints.
- Gelatin: This is a processed form of collagen obtained by boiling the connective tissue of animals. Gelatin contains large collagen molecules and can be less easily absorbed than a hydrolyzed collagen.
- Collagen mixtures: Some additives contain a combination of various types of collagen, as well as other ingredients, such as vitamins, minerals and antioxidants.
-
2 Sources of collagen
Collagen for additives is obtained from various sources of animal origin:
- Catual cattle (bullry collagen): The main source of collagen types I and III.
- Pigs (pork collagen): Also the source of collagen types I and III.
- Fish (sea collagen): It mainly contains a collagen type I. It is believed that sea collagen has higher bioavailability than collagen from other sources.
- Chicken (chicken collagen): The main source of collagen type II.
-
3 Output and dosage forms
Collagen additives are available in various forms of release:
- Powder: The most common form. The powder can be added to water, juice, smoothies or other drinks.
