Collagen's key properties stem from its role as the body's main structural protein. It provides skin elasticity, joint function, and bone density. This article discusses its fundamental importance for health.
What is collagen and what is its structure?
Collagen is the most important protein in the human body, constituting approximately 30% of all proteins. It serves as a building block of connective tissue, which holds organs and tissues together . Its unique structure resembles a triple helix—three polypeptide chains twisted around each other. This structure gives it extraordinary tensile strength. Each chain is composed of amino acids, primarily glycine, proline, and hydroxyproline. These amino acids give collagen its specific properties and enable the formation of stable, strong fibers.
The main types of collagen and their distribution
Nearly 30 types of collagen have been identified in the human body, but several of them are crucial.
-
Type I collagen is the most common, making up 90% of the total. It forms the skin, bones, tendons, and ligaments, giving them their hardness.
-
Type II is the main component of joint cartilage, where it forms a network of fibers responsible for shock absorption and smooth movements.
-
Type III collagen often occurs with type I. It is crucial for the elasticity of the skin, blood vessels, and internal organs, creating a delicate framework for them.
Key properties of collagen and the body's health
The fundamental properties of collagen are related to its ability to form structures that serve as scaffolding for cells. It helps organs maintain their shape. This protein is also essential in the wound healing process. When tissue is damaged, fibroblasts produce collagen to create new tissue that fills the gap. Its presence in blood vessel walls provides them with elasticity and strength, which is crucial for proper blood circulation and maintaining adequate blood pressure.
The influence of collagen on the condition of the skin, hair and nails
Collagen is often called the protein of youth because it is responsible for the skin's density, firmness, and hydration. In the dermis, it forms a dense mesh that supports the epidermis. With age, collagen production declines, and existing fibers degrade, leading to wrinkle formation. This protein is also an important structural component of hair and nails. By providing amino acids for keratin production, it influences their structure. Adequate collagen levels make hair stronger and nails less brittle.
How does collagen affect the musculoskeletal system?
Collagen is also fundamental to the musculoskeletal system. It is the main component of joint cartilage, which covers the surfaces of bones in joints. It keeps the cartilage smooth and elastic, reducing friction and enabling movement. A deficiency in this protein leads to cartilage abrasion, which can cause pain and stiffness. Collagen is also a crucial component of bones, where it forms the matrix on which minerals are deposited. It gives bones elasticity, protecting them from fractures and increasing their resistance to stress.
The role of collagen in digestive health
Collagen-rich connective tissue also builds the intestinal wall, creating a protective barrier. The amino acids contained in collagen, especially glycine and glutamine, play a role in maintaining the integrity of the intestinal epithelium . By strengthening the connections between cells, they can contribute to the tightness of the intestinal barrier. This limits the penetration of unwanted substances from the gastrointestinal tract into the bloodstream. The proper structure of this barrier is crucial for maintaining the balance of the intestinal microbiota and the functioning of the body's immune system. It is worth noting, however, that few studies have suggested a positive effect of collagen on intestinal health, and this topic is still not widely discussed among scientists.
Collagen deficiency – causes and visible effects
Collagen production naturally declines after the age of 25, and this process accelerates during menopause. External factors also contribute to collagen loss: excessive sun exposure, smoking, a diet high in sugar, and a deficiency in vitamin C, which is essential for its synthesis. The effects of deficiency are immediately apparent: skin thins, wrinkles appear, and hair and nails become brittle. A thorough understanding of the properties of collagen facilitates understanding these processes.
How to replenish collagen levels in the body?
Collagen levels can be supported through diet, such as bone broths. However, the amount of protein supplied this way may be insufficient. Therefore, supplements are gaining popularity. The most effective form is hydrolysates, or highly absorbable collagen peptides. Understanding the properties of collagen helps in choosing a supplement. Beef products, valued for their amino acid profile, dominate the market. By choosing a supplement such aseatyx hydrolyzed bovine collagen , you provide your body with ready-made peptides for synthesis.
Potential Benefits of Collagen Supplementation
Regularly taking collagen supplements can provide a range of health benefits. Improved skin hydration, elasticity, and fine lines are observed. Physically active individuals and the elderly may experience reduced joint pain and improved mobility. Supplementation can also support bone health by affecting bone density. When analyzing the properties of collagen, it's important to remember that effects vary from person to person and depend on diet, regular use, and lifestyle.
Are there any contraindications to the use of collagen?
Collagen supplements are considered safe and well-tolerated. Rare side effects are limited to mild gastrointestinal discomfort. The main contraindication is an allergy to the protein source. People allergic to fish should avoid marine collagen, and those allergic to beef should avoid bovine collagen. Always choose products from reputable manufacturers who offer high-quality products, such as eatyx 's liquid bovine collagen , which facilitates daily use.
