Comparison of dietary supplements with collagen: which is better to buy?
Part 1: Collagen – the basis of the health of the skin, joints and bones
1.1. What is collagen and its role in the body:
Collagen is the most common protein in the human body, which is about 30% of the total mass of proteins. It is the main structural component of connective tissue, which provides its strength and elasticity. Collagen forms fibers that play the role of a kind of frame, supporting organs and tissues, as well as ensuring their flexibility and resistance to mechanical influences.
The main functions of collagen:
- Structural support: Collagen forms the structure of the skin, bones, cartilage, tendons, ligaments, blood vessels and other organs. It provides their integrity and resistance to deformation.
- Elasticity and elasticity of the skin: Collagen fibers give the skin elasticity and elasticity, preventing the formation of wrinkles and sagging.
- Joint health: Collagen is the main component of cartilage, which covers the surface of the joints and provides their smooth sliding. It helps to reduce friction and prevents the wear of cartilage.
- Bone strength: Collagen is part of bone tissue, ensuring its flexibility and resistance to fractures.
- Hair and nail health: Collagen helps strengthen hair and nails, making them more durable and shiny.
- Vascular function: Collagen forms the walls of blood vessels, ensuring their strength and elasticity.
1.2. Types of collagen and their features:
There are many types of collagen, but the most common are the following:
- Type and: The most common type of collagen, which is about 90% of the total collagen in the body. It is located in the skin, bones, tendons, ligaments, teeth and other tissues. It provides the strength and elasticity of these tissues.
- Type II: The main type of collagen contained in cartilage. It provides depreciation and joint protection from wear.
- Type III: Contained in the skin, vessels and internal organs. It contributes to the elasticity and regeneration of tissues.
- Type IV: It is part of basal membranes that support cells and tissues.
- Type V: Contained in the hair, placenta and other fabrics.
Different types of collagen have a different structure and functions, so it is important to choose a dietary supplement with a collagen containing types necessary to solve specific problems. For example, to improve the condition of the skin, it is recommended to choose dietary supplements with a collagen type I and III, and to support joint health – with a collagen type II.
1.3. Factors affecting the production of collagen:
With age, the production of collagen in the body naturally decreases. This leads to a deterioration in the condition of the skin, joints and bones. However, in addition to age, other factors affect the production of collagen:
- Age: With age, the production of collagen decreases, starting from about 25-30 years. This leads to wrinkles, sagging of the skin, joint pain and other age -related changes.
- Ultraviolet radiation: Solar radiation destroys collagen fibers in the skin, accelerating the aging process.
- Inal meals: The lack of vitamins and minerals necessary for the synthesis of collagen can lead to a decrease in its production. Vitamin C, copper, zinc and silicon are especially important.
- Smoking: Smoking worsens the blood supply to the skin and other tissues, which leads to a decrease in collagen production.
- Stress: Chronic stress can negatively affect the production of collagen.
- Hormonal changes: Hormonal changes, for example, during menopause, can lead to a decrease in collagen production.
- Lack of sleep: Insufficient sleep can affect the general state of health and, as a result, the production of collagen.
1.4. Signs of collagen deficiency:
Signs of collagen deficiency can appear differently, depending on the degree of deficiency and individual characteristics of the body. The most common features:
- Wrinkles and sagging of the skin: Reducing the elasticity and elasticity of the skin, the appearance of wrinkles, sagging of the skin on the face, neck and other areas of the body.
- Joint pain: Pain and stiffness in the joints, especially after physical activity or prolonged stay in one position.
- Weakening of bones: Reducing bone density, increased risk of fractures.
- Problems with hair and nails: Breeding and dry hair, slow growth, stratification of nails.
- Digestive problems: Disruption of the gastrointestinal tract, constipation, leaky intestine syndrome.
- Slow wound healing: Slow healing of wounds and cuts.
- Cellulite: Increased visibility of cellulite.
1.5. Collagen in food:
Collagen is found in animal products, such as:
- Meat: Especially a lot of collagen in beef, pork and chicken.
- Fish: Fish, especially leather and bones, contains collagen.
- Broths: The broths cooked on the bones contain gelatin, which is a hydrolyzed collagen.
- Gelatin: Gelatin is a pure collagen obtained from bones and animal skin.
Despite the fact that collagen is found in food, its absorption may be difficult. Therefore, in some cases, it is recommended to take dietary supplements with collagen.
Part 2: Types of collagen dietary supplements and their characteristics
2.1. Hydrolyzed collagen:
The hydrolyzed collagen, also known as collagen peptides, is the most common form of collagen in dietary supplements. It is a collagen that was split into smaller fragments – peptides. This facilitates its absorption by the body.
Advantages of hydrolyzed collagen:
- High bioavailability: Easily absorbed by the body.
- A variety of output forms: Available in various forms, such as powders, capsules, tablets and liquids.
- Universality: Suitable for solving various problems associated with collagen deficiency.
2.2. Non-unauthorized collagen type II (UC-II):
A non-reinvented collagen type II (UC-II) is a collagen that was not treated with high temperatures or acids. It retains its natural three -dimensional structure. It is believed that UC-II can affect the immune system, reducing inflammation in the joints and contributing to their restoration.
Advantages UC-II:
- Specialized action: Effective for maintaining joint health.
- Small dosages: Less dosage is required compared to a hydrolyzed collagen.
2.3. Sea collagen:
Sea collagen is obtained from leather and bones of fish. It is considered one of the cleanest and easily digestible types of collagen. Sea collagen is rich in amino acids necessary for the synthesis of collagen in the body.
Advantages of sea collagen:
- High bioavailability: Easily absorbed by the body.
- Hypoallergeny: Suitable for people with allergies to other sources of collagen (for example, beef or pork).
- Wealth with amino acids: Contains the necessary amino acids for collagen synthesis.
2.4. Plant “collagen”:
Strictly speaking, plant collagen does not exist. Collagen is a protein that is found only in animal tissues. However, some plant extracts contain substances that can stimulate collagen production in the body. Such substances include:
- Vitamin C: It is necessary for the synthesis of collagen.
- Silicon: Participates in the formation of collagen fibers.
- Proline and Lysine: Amino acids necessary for the synthesis of collagen.
Plant “collagen” can be useful for maintaining the health of the skin and joints, but they are not a direct source of collagen.
2.5. Forms of the release of collagen dietary supplements:
Collagen dietary supplements are available in various forms:
- Powder: Collagen powder can be dissolved in water, juice or other drinks. This is a convenient form for those who want to control the dosage.
- Capsules and tablets: Capsules and collagen tablets are convenient for reception on the road or at work.
- Liquid: Liquid collagen is easily absorbed by the body.
- Chewing tablets and marmalade: Convenient and pleasant shape for children and adults.
- Creams and serums: Collagen in cosmetics can improve the condition of the skin, but its penetration into the deep layers of the skin is limited.
The choice of release form depends on individual preferences and ease of use.
