Collagen is the most abundant protein in the human body, which plays a key role in maintaining the structure of the skin, bones, joints, muscles and connective tissue. As the body's basic building block, collagen provides elasticity and firmness to tissues, while aiding in cell regeneration and slowing down the aging process.
Collagen loss naturally occurs with age, which can affect skin elasticity, joint mobility and bone strength. Ingesting collagen through a nutrient-rich diet or supplements can help maintain the body's health and vitality.
What is collagen and why is it important for the body?
Collagen is the most abundant protein in the human body, making up 30% of total proteins and providing structure, strength and flexibility to tissues. It is considered a building block because it is present in the skin, bones, joints, muscles, tendons and ligaments, but also in internal organs such as the heart and intestines.
This protein plays a key role in maintaining the structure of the skin, maintaining its firmness and elasticity. In bones and joints, collagen acts as a shock absorber, allowing mobility and reducing the risk of injury. Also, connective tissues - such as tendons and ligaments - retain their firmness and flexibility thanks to collagen. Without collagen, the body would not be able to function in the way we are used to, as it plays a central role in connecting and supporting all tissues.
With age, the body's collagen production declines, leading to visible changes such as wrinkles, weaker skin, joint pain and reduced mobility. That's why maintaining collagen levels is key to health and vitality.
How does collagen affect skin health and elasticity?
Collagen is the main protein responsible for the youthful appearance of the skin. It supports the dermis, the middle layer of the skin, where it acts as a natural support and helps the skin maintain elasticity and firmness. Also, collagen contributes to the hydration of the skin, because it binds water in the tissues, providing a smooth and hydrated surface.
With aging, the body naturally reduces collagen production, which leads to loss of skin elasticity, wrinkles and sagging tissue. Factors such as sun exposure, smoking and stress can further accelerate the loss of collagen, making the skin more vulnerable to external influences. A lack of collagen not only affects aesthetics, but can also lead to slower skin recovery after injuries.
Taking collagen through diet or supplements can help restore its presence in the skin, improving its appearance and health. Collagen supplements stimulate the natural production of this protein, while at the same time supporting cell regeneration and reducing the visibility of signs of aging.

Collagen in joints and bones - the key to mobility
Collagen is necessary for the health of joints, as it is the main component of cartilage - tissue that cushions movements and prevents friction between bones. Its presence ensures the flexibility of the joints and reduces the risk of injuries such as sprains or cartilage damage. With age, a decrease in collagen levels leads to thinning of the cartilage, which can result in joint pain and swelling osteoarthritis.
Collagen also plays a key role in maintaining bone strength. It makes up about 90% of the organic part of bones and helps in their regeneration and resistance. A drop in collagen levels can weaken bone structure and increase the risk of osteoporosis, a condition characterized by increased bone fragility. Collagen supplements can help strengthen bones and joints, improving overall mobility and quality of life, especially in the elderly.
How does collagen loss affect the body?
Collagen production in the body naturally begins to decline after the age of 25, and this process is further accelerated by factors such as stress, unhealthy diet, smoking and excessive exposure to UV radiation. This decline affects various aspects of the body's health and aesthetics.
The lack of collagen is first noticed on the skin - it becomes thinner, loses elasticity and wrinkles appear. Hair becomes brittle and tends to fall out, while nails become weaker. In the joints, a lack of collagen leads to pain, stiffness and an increased risk of injury, while bones lose density, which increases the risk of fractures. Also, the reduction of collagen can lead to weaker muscle regeneration and a general decline in the body's vitality.
Natural sources of collagen - what to eat to increase intake?
Foods rich in collagen can significantly contribute to maintaining health and a youthful appearance. Some of the best natural sources include:
- Chicken bones and skin: Rich in type II collagen, ideal for joints.
- Fish: Fish skin in particular contains collagen that is easily digestible and absorbable.
- Eggs: Egg whites are rich in proline, an amino acid essential for collagen synthesis.
Proper preparation of these foods can further increase collagen intake. For example, cooking chicken or beef bones in water for a long time creates a collagen-rich broth (known as broth). This broth is not only rich in collagen, but also other nutrients like minerals and amino acids that support bone and joint health.
Adding natural sources of collagen to your daily diet is an easy way to support your body and keep it healthy and vital.
Is it safe to take collagen as a dietary supplement?
Collagen supplements are considered safe for most people. Since they are made from natural sources such as beef, fish or pig collagen, they rarely cause allergic reactions. Collagen is usually hydrolyzed (turned into collagen peptides), making it easily digestible and suitable for absorption.
The recommended daily intake of collagen varies, but is usually within the range between 2.5 g and 10 g per day, depending on the purpose of use – for skin, joints or muscles. When choosing supplements, it is important to pay attention to the quality of the product. Look for those that contain hydrolyzed peptides, come from verified sources and have additional benefits like vitamin C, which promotes collagen synthesis. Also, avoid products with unnecessary additives and artificial flavors.
It is always advisable to consult a doctor before introducing new supplements, especially if you have health problems or are taking medication.
What types of collagen are there and how to choose them?
Collagen consists of several types, but three are the most important for the human body:
- Type I: The most common type of collagen in the body, responsible for the health of the skin, bones and ligaments. It is ideal for people who want to improve the appearance of their skin and reduce wrinkles.
- Type II: Present in cartilage, this type is crucial for joint health. Recommended for people who suffer from joint pain or want to improve mobility.
- Type III: Often found with type I, it helps maintain skin elasticity and blood vessel health.
When choosing supplements, it is important to choose one that suits your needs. If you want better skin and hair, focus on type I. For joint health, choose products with type II collagen, while a combination of types I and III provides comprehensive support.
Collagen for hair and nails - does it really help?
Collagen plays a significant role in strengthening hair and nails. As a building protein, it provides the amino acids necessary for the production of keratin, the main protein that makes up hair and nails. Also, collagen improves circulation in the scalp, which promotes the growth of stronger and thicker hair.
Studies have shown that regular intake of collagen can reduce the brittleness of nails and accelerate their growth. In addition, collagen can help reduce hair loss and improve its texture, making it softer and shinier.
For best results, it is recommended to combine collagen supplements with a balanced diet rich in vitamins and minerals, as well as adequate hydration and care. Collagen can be your ally in achieving healthy and well-groomed hair and nails, but it's important to have realistic expectations - results come gradually and require continuity.
How is collagen used in skin care?
Collagen is key to the structure and elasticity of the skin, so collagen-based products, such as creams, serums and masks, are popular in the face care routine. These products often contain hydrolyzed collagen, which is used to hydrate the skin and improve its appearance. Topical collagen helps to restore the surface layers of the skin, making it smoother and firmer.
Although collagen-based creams and serums are useful for immediate results, their effectiveness in deeper skin regeneration is limited. Collagen is present in the surface layer of the skin, but as collagen in the body naturally decreases with age, topical products cannot directly contribute to the production of collagen in the connective tissue and dermis.
In contrast, oral intake of collagen showed more profound effects. Collagen powder, when ingested, is broken down in our body into peptides and amino acids that stimulate the natural production of collagen and the regeneration of skin and nails. Studies have shown that oral collagen for the skin can reduce wrinkles, improve hydration and increase skin elasticity, while topical products provide support for the skin's surface layer.
Collagen powder - how to use it and what results to expect?
Collagen powder is a practical and effective way to increase protein intake in the body, especially collagen types I and III, which are crucial for skin, bones and connective tissues. This hydrolyzed form of collagen is easily absorbed, so its effectiveness in tissue and skin regeneration is high. Collagen is used to reduce the risk of injury and speed up recovery, especially in active individuals.
One of the main advantages of collagen powder is its ease of use. Can be added to:
- Smoothies: Combine collagen with fruits and vegetables for a refreshing and nutritious meal.
- Coffee: Adding collagen to your morning coffee is a practical way to start the day with an extra protein boost.
- Broths and soups: Traditional soups, prepared by cooking chicken and other animal bones, are a natural source of collagen and can easily be enriched with additional collagen powder.
Collagen is important for skin, joint and bone health, and regular use of collagen powder can reduce the risk of injury and contribute to long-term tissue and skin regeneration. Adding this supplement to the diet provides support not only for the appearance of the skin but also for overall health, because collagen in our body naturally decreases with age. By using collagen powder, it is possible to slow down the aging process and maintain tissue and organism vitality.
