What is collagen and what benefits does it have for general health and skin?
Posted by Ivatherm
In recent years, interest in the role and benefits of amino acids has become more complex and intense. From collagen food supplements to adopting a protein-rich diet and using dermo-cosmetic products containing collagen peptides, there is a growing need to stimulate its natural production and supplement any deficiencies.
In this article, you will learn what collagen is, what types exist and what functions it has in the body, what causes its levels to decrease, how you can prevent or treat deficiencies, and what risks may arise from excessive consumption.

What is collagen
Collagen is a solid, insoluble, and fibrous substance and also the most abundant protein in the human body – one third of all proteins. In most types of collagen, its molecules form long fibers that act as support structures and anchor cells to each other. Collagen dictates the strength and elasticity of the skin.
As you age, endogenous collagen production decreases, but it is still extremely important for the health of bones, joints, and skin. That's why collagen as a food supplement and cosmetic ingredient becomes a necessity.
Collagen can be of two types, depending on its source:
Natural collagen (endogenous) – produced by the body, plays an essential role in maintaining the health of skin, joints, bones, muscles, and other tissues
Exogenous collagen (synthetic) – comes from external sources, such as food supplements, injections, or cosmetic products
Types of collagen and their role
There are at least 16 different types of collagen. The most important of these account for over 90% of the total collagen in the human body:
Type I collagen – long, dense fibers that provide structure to skin, bones, tendons, fibrous cartilage, connective tissues, and teeth
Type II collagen – less compact fibers, found in elastic cartilage that cushions joints
Type III collagen – supports the structure of muscles, organs, and arteries
Type IV collagen – found in the epidermal layers and contributes to the filtration function of substances
Functions and benefits of collagen for the body
Collagen performs a wide variety of functions in the body. It supports overall health and plays an important role in many systems and tissues:
Collagen and the skeletal and articular systems
Lubricates joints – along with hyaluronic acid, ensures the viscous texture of synovial fluid
Contributes to cartilage repair
Reduces inflammation in the joints and alleviates pain
Has a preventive role for rheumatoid arthritis, osteoarthritis, arthrosis, osteoporosis, or gout
Supports cellular regeneration in ligaments, tendons, and joints
Ensures motor skills, mobility, and flexibility of the body
Supports optimal mineralization of the skeletal system, including teeth
Collagen and the muscular system
Collagen peptides contribute to post-effort muscle recovery, supporting the regeneration of overstressed fibers and their hydration.
Collagen and the respiratory system
Collagen is present in lung tissues and membranes. It acts in synergy with elastin to ensure lung elasticity and optimal function.
Collagen and the circulatory system
Naturally occurring collagen in the circulatory system strengthens blood vessels and supports cell regeneration, while also supporting their elasticity.
Collagen and the gastrointestinal system
This protein helps balance secretions and stomach acid, preventing dehydration and stimulating digestion. Collagen supports the regeneration of cells in the intestinal wall and aids in the process of fat metabolism.
Other benefits of collagen
Maintaining ocular health – collagen hydrates and lubricates the cornea and tones the eyeball
Tissue repair – enables cellular regeneration
Counteracting the harmful effects of external factors – healing and regenerating functions for skin, hair, and nails
Maintaining skin health and beauty – ensures skin elasticity and has a preventive role for wrinkles, cellulite, and stretch marks
Collagen for the face: effects and benefits
Collagen is a major component of the skin. It plays a role in making it more resistant, ensuring its elasticity, and hydrating it. Because endogenous collagen production decreases with age, the skin tends to become drier, less firm, and lose its hydration, allowing wrinkles to form.
Collagen peptides and supplements containing them can slow down the aging process, reducing the appearance of wrinkles and hydrating the skin. At the same time, exogenous collagen can also stimulate the production of endogenous collagen.
Collagen Elastin is the first beauty food supplement launched by Ivatherm, which visibly reduces wrinkles in 28 days. Part of the IvaRG range, it contains marine collagen and elastin peptides, L-lysine, natural vitamin C from Acerola, and zinc. The peptides are rapidly absorbed into the bloodstream, directly reaching target tissues and stimulating fibroblasts in the skin to produce collagen fibers.
The most important factor leading to a decrease in endogenous collagen production is aging. This occurs as a result of the natural aging process of cells and tissues, and hormonal changes associated with menopause and andropause have a negative impact. After the age of 20, endogenous collagen decreases, on average, by approximately 1% each year.
Exposure to ultraviolet radiation
There is a proven link between the decline in natural collagen production and sun exposure. UV radiation has a negative impact on endogenous collagen through several mechanisms, including causing changes in the DNA of collagen-producing cells.
Smoking
Smoking has often been associated with premature aging. By reducing the amount of oxygen supplied to tissues, this habit hinders cellular regeneration, and the chemicals contained in cigarettes contribute to increased oxidative stress.
Inflammation-stimulating diet
Sugar, in particular, can be considered collagen's primary enemy. It can lead to the fragmentation of this protein, weakening the foundation of the epidermis and dermis, causing premature skin aging. A diet high in sugars, simple carbohydrates, and processed meats can activate the immune system and stimulate inflammation.
Stress
Stress can have inflammatory effects and contribute to a decrease in natural collagen production. Stress causes disproportionate hormonal surges of cortisol – and when the body's resources are used to combat stress, endogenous collagen production decreases significantly.
Genetic factors
Genetic inheritance is crucial for determining how much collagen your own body can produce. It is advisable to focus on addressing the factors you can influence, such as diet and lifestyle.
How to treat collagen deficiencies and stimulate its natural production
There are countless ways to increase collagen levels. From taking food supplements to incorporating ingredients that contain collagen or stimulate its production into your diet:
Hyaluronic acid
Hyaluronic acid is an important compound for collagen that is part of the skin. It is found in foods rich in amino acids, such as legumes and root vegetables.
Vitamin C
Vitamin C cannot be produced by the body and is absorbed strictly through diet. It is found in large quantities in citrus fruits and leafy green vegetables and plays an important role in protecting the skin's natural barrier, as well as in stimulating collagen production.
Ivatherm Anti-Wrinkle Cream contains vitamins C, A, and E, which act against free radicals and prevent premature skin aging.
Aloe vera
Aloe vera extract has soothing properties for the skin. Administered as a food supplement, this extract can double the amount of hyaluronic acid and collagen produced by the body. It stimulates cell regeneration both when administered externally and when ingested.
Ginseng
Ginseng has the property of increasing the amount of collagen in the blood, has anti-inflammatory action, and antioxidant properties. It can be consumed in the form of tea, tinctures, or food supplements.
Antioxidants
Antioxidants are substances that help the body protect itself against free radicals. Antioxidants that help rejuvenate the skin are found in green tea, berries, pomegranates, coffee extracts, cinnamon, and essential oils.
Retinol
Retinol is part of a type of antioxidants used to stimulate endogenous collagen production. It contributes to the longevity of collagen fibers and inhibits enzymes that could destroy them.
Coenzyme Q10
A study involving the administration of a combination of coenzyme Q10 and marine collagen concluded that this mix offers benefits: improved dermal density, visible reduction of wrinkles around the eyes, and improved skin texture.
Ivatherm Anti-Wrinkle and Anti-Dark Circles Eye Contour Cream contains amino acids that prevent the degradation of collagen and elastin fibers, reduce inflammation, and improve blood microcirculation in the delicate area around the eyes.
Red light therapy
Red light therapy is a fast and safe way to stimulate collagen production in the skin. It is a non-invasive method that has no side effects and can even be performed at home.
Protecting the skin from environmental factors
It is important to protect the skin from ultraviolet radiation and prevent sunburn. One solution is to maintain skin hygiene – gentle cleansing and daily exfoliation. Applying effective sun protection creams and lotions can prevent collagen loss.
Food sources rich in collagen
Egg white
Citrus fruits
Berries
Red and yellow vegetables
Garlic
White tea
Leafy green vegetables
Cashew nuts
Beans, peas, chickpeas, lentils, and soy

Collagen: contraindications and adverse effects of abuse
Collagen food supplements are generally well-tolerated. In very rare cases, there may be adverse reactions to their administration.
Most often, these supplements contain ingredients with allergenic potential, such as fish, seafood, or eggs. People who suffer from allergies to these foods should avoid ingesting them, including in the form of food supplements.
Another possible adverse effect is nausea and bloating. Furthermore, collagen supplements can cause heartburn or a false sense of satiety.
