Collagen in dietary supplements: what you need to know when buying

Section 1: What is collagen and why is it important?

Collagen is the most common protein in the human body, which is about 30% of its total protein mass. It is the main structural component of connective tissue, which plays a key role in maintaining the structure and functions of various organs and systems, including skin, bones, cartilage, tendons, ligaments, blood vessels and even the cornea of the eye. Collagen provides the strength, elasticity and elasticity of these tissues, allowing them to withstand the loads and maintain their shape.

1.1 The role of collagen in the body:

Collagen performs many important functions:

Structural support: It forms a frame for cells and tissues, providing their support and stability. In the skin, collagen is responsible for its elasticity and smoothness, preventing the formation of wrinkles. In the bones, he gives them strength and resistance to fractures. In cartilage, it provides depreciation and flexibility of the joints.
Wound healing: Collagen plays an important role in the healing process of wounds, stimulating the formation of new tissue and contributing to the closure of defects. He also participates in the formation of scars.
Transport of substances: Collagen is involved in the transport of nutrients and oxygen to cells, ensuring their normal functioning.
Organs protection: It protects the internal organs from damage, forming a dense shell around them.
Joint function: Collagen is the main component of cartilage, ensuring its strength and elasticity. It prevents friction between bones and contributes to the normal functioning of the joints.
Skin health: Collagen supports the elasticity and elasticity of the skin, preventing the formation of wrinkles and maintaining its youth. It also helps to moisturize the skin and improve its texture.
Hair and nail health: Collagen strengthens the hair and nails, making it more durable and resistant to damage. It also stimulates the growth of hair and nails.

1.2 Types of collagen:

There are at least 28 different types of collagen, each of which performs certain functions in the body. However, the following types are the most common and important:

Type and: The most common type of collagen, which is about 90% of the total collagen in the body. It is found in the skin, bones, tendons, ligaments, teeth and other tissues. He is responsible for the strength and elasticity of these tissues.
Type II: The main type of collagen, which is contained in cartilage. It provides depreciation and flexibility of the joints.
Type III: Contained in the skin, vessels and internal organs. He is responsible for the elasticity of these tissues and is involved in the healing process of wounds.
Type IV: Contained in basal membranes, which are thin layers of tissue separating epithelial cells from connective tissue. It supports the structure of basal membranes and participates in the filtering of substances.
Type V: Contained in the hair, placenta and other fabrics. Its function is not sufficiently studied.

1.3 Factors affecting the synthesis of collagen:

With age, as well as under the influence of various factors, the synthesis of collagen in the body decreases. This leads to a deterioration in the condition of the skin, bones, joints and other tissues. The main factors affecting the synthesis of collagen:

Age: With age, collagen synthesis naturally decreases, starting from about 25-30 years.
Ultraviolet radiation: The effect of sunlight destroys collagen in the skin, leading to its aging and the formation of wrinkles.
Smoking: Smoking worsens the blood supply to the skin and reduces the synthesis of collagen, accelerating its aging.
Inal meals: The lack of vitamin C, amino acids and other nutrients necessary for the synthesis of collagen can lead to its deficiency.
Stress: Chronic stress can negatively affect the synthesis of collagen.
Hormonal changes: Hormonal changes, such as menopause in women, can lead to a decrease in collagen synthesis.
Diseases: Some diseases, such as autoimmune diseases and diseases of the connective tissue, can affect the synthesis of collagen.

Section 2: Collagen in dietary supplements: types and forms

In connection with a decrease in the natural synthesis of collagen, many people resort to receiving collagen in the form of biologically active additives (dietary supplements). On the market there are many different types and forms of collagen, which differ in source, method of processing and efficiency.

2.1 Collagen sources:

The main sources of collagen for dietary supplements are:

Animal collagen: They are obtained from leather, bones and cartilage of cattle (bullish collagen), pigs (pork collagen) and poultry (chicken collagen). The animal collagen contains all the main types of collagen, including the type I, II and III. It is relatively inexpensive and widely available.
Sea collagen (fish collagen): Received from leather, bones and scales of fish. Sea collagen contains mainly type I collagen, which is considered the most easily absorbed by the body. It is more expensive than animal collagen, but has a higher bioavailability and lower risk of allergic reactions.
Plant collagen: Strictly speaking, plants do not produce collagen. However, there are plant components that stimulate the production of collagen in the body, such as vitamin C, the amino acids of the PROLIN and the Lizin, as well as the extracts of some plants, such as the Asian centella. The dietary supplements containing these components are often called “plant collagen.”

2.2 Collagen forms:

Collagen in dietary supplements is represented in various forms:

Hydrolyzed collagen (collagen peptides): This is the most common form of collagen in dietary supplements. Hydrolysis is the process of splitting large collagen molecules into smaller peptides, which are easier to absorb by the body. The hydrolyzed collagen dissolves well in water and has no smell and taste.
Non-unauthorized collagen (UC-II): This is a collagen that was not subjected to heat treatment or hydrolysis. It retains its three -dimensional structure and is considered more effective for maintaining joint health. UC-II is usually obtained from chicken cartilage and contains type II collagen.
Gelatin: This is a product of partial hydrolysis of collagen. Gelatin is a protein that has geling properties. It can be used to prepare desserts, jelly and other dishes. The gelatin contains all the amino acids necessary for the synthesis of collagen, but its digestibility is lower than that of a hydrolyzed collagen.
Powder: Collagen in powder form is usually a hydrolyzed collagen. It can be added to drinks, smoothies or yogurt.
Capsules and tablets: Collagen in capsules and tablets is convenient to take and dose. Usually they contain a hydrolyzed collagen or UC-II.
Liquid collagen: Collagen in liquid form usually contains hydrolyzed collagen and additional ingredients, such as vitamins, minerals and antioxidants.

2.3 Comparison of various forms of collagen:

Collagen shape	Advantages	Flaws	Bioavailability	Application
Hydrolyzed collagen	It is easily absorbed, well dissolved, does not have smell and taste, contains a wide range of amino acids, suitable for improving the condition of the skin, hair, nails and joints.	Less effective for maintaining joint health than UC-II.	High	To improve the condition of the skin, hair, nails, bones and joints, to maintain the health of connective tissue.
Non-unauthorized collagen (UC-II)	Effective for maintaining joint health, reduces pain and inflammation, improves joint mobility.	It is less effective for improving the condition of the skin, hair and nails, it contains only the type II collagen, more expensive than hydrolyzed collagen.	Average	To maintain joint health, to reduce pain and inflammation in arthritis and other joint diseases, to improve joint mobility.
Gelatin	A cheap and affordable source of collagen contains all the necessary amino acids, can be used for cooking.	Digestibility is lower than that of a hydrolyzed collagen can have a specific taste and smell.	Low	To maintain the health of connective tissue, to improve the condition of the skin, hair and nails, for cooking.

Section 6: Collagen in dietary supplements: myths and reality

There are many myths and errors associated with the reception of collagen in the form of dietary supplements. It is important to understand what is true and what is fiction.

6.1 Myth: Rollen from dietary supplements is directly built into the skin and joints.

Reality: The collagen from dietary supplements is broken down in the digestive system into amino acids and peptides, which are then used by the body to synthesize its own collagen. It does not directly integrate into the skin and joints. However, studies have shown that the intake of collagen in the form of dietary supplements can stimulate the synthesis of collagen in the body, leading to an improvement in the condition of the skin, joints and other tissues.

6.2 myth: all types of collagen are equally effective.

Reality: Various types of collagen perform different functions in the body. Type I collagen is most useful for skin, hair and nails, type II for joints, type III – for blood vessels and internal organs. In addition, the form of collagen (hydrolyzed, UC-II, gelatin) also affects its effectiveness.

6.3 Myth: Collagen is a miraculous remedy for all diseases.

Reality: Collagen is not a panacea. It can help improve the condition of the skin, joints and bones, but cannot cure all diseases. Collagen should be considered as an addition to a healthy lifestyle, including a balanced diet, regular physical exercises and sufficient sleep.

6.4 Myth: Collagen is useless if you do not take it with vitamin C.

Reality: Vitamin C is necessary for the synthesis of collagen in the body. However, if your diet contains enough vitamin C, then the additional technique of vitamin C along with the collagen is not mandatory.

6.5 Myth: Collagen is addictive.

Reality: Collagen is not addictive. This is a natural protein that is contained in the human body.

6.6 Myth: Collagen intake can lead to side effects.

Reality: Collagen is usually well tolerated, but in some cases side effects can occur, such as stomach disorder or allergic reactions. However, these side effects are rare and usually pass on their own.

6.7 Myth: Collagen is an expensive dummy.

Reality: A high -quality collagen from a reliable manufacturer can be quite expensive. However, if you choose the correct type and shape of the collagen, observe the recommended dosage and lead a healthy lifestyle, then taking collagen can bring tangible benefits for the health of the skin, joints and bones.
