Did you know that collagen - our body's key structural protein - begins to disappear as soon as we reach the age of 25? While these changes may seem subtle at first, over time we begin to notice their effects: wrinkles, joint pain, loss of skin elasticity. But what exactly happens to our bodies when collagen levels decline? What health risks are involved? And what can we do to counteract these changes?
Collagen plays a key role in maintaining the structure and function of many tissues in our bodies, including skin, joints, bones, blood vessels, muscles and even internal organs. Its deficiency has far-reaching effects, affecting not only our appearance, but also the health of the entire body. Understanding what happens in the body when collagen is deficient can help us take better care of our health and counteract the effects of aging.
Decline in collagen synthesis - what happens after age 25?
An interesting fact that not many people know: starting at age 25, collagen synthesis in our body begins to decline by about 1% per year. As we age, this process accelerates, and around age 40 it decreases even more sharply. Why does this matter? Because collagen is responsible for skin elasticity, bone strength and joint health.
Think of it as the erosion of a building's structure: if collagen acts as “scaffolding” in your body, the gradual loss of this protein causes the foundation to begin to weaken. The skin loses its firmness, wrinkles appear, and regenerative processes slow down. Did you know that it is because of the decline in collagen that wounds take longer to heal and joints become less flexible?
Collagen - what exactly is it and why is it so important?
Collagen is the body's main structural protein, accounting for as much as 30% of the total protein mass. It is the basis of connective tissue, which supports, protects and connects various structures of the body. Without collagen, our skin, bones, joints, muscles and even internal organs would not be able to maintain their integrity.
Collagen acts as a “biological glue” that holds cells in place. It's what makes our skin firm, our bones strong and our joints flexible. It's also found in blood vessels, the cornea of the eye and teeth, providing them with structural support.
Think about it, what happens when collagen starts to become scarce? The skin loses firmness, wrinkles appear, joints begin to ache, and wounds heal more slowly. All these are visible signs that our body is losing its ability to regenerate effectively.
What causes collagen deficiency?
Collagen deficiency is not only due to the aging process. There are many factors that can accelerate the process or further weaken it. Here are the most important of them:
-
Aging
This is the main cause of the decline in collagen synthesis. After the age of 25, the rate of collagen production decreases, and around the age of 40 there is a sharp decline. As we age, the body loses the ability to regenerate and produce new collagen fibers. The effects of this process are visible both externally and internally - from wrinkles to joint problems. -
UV radiation
Ultraviolet (UV) radiation destroys collagen fibers in the skin, leading to faster aging. Sun exposure without sunscreen accelerates collagen degradation, causing wrinkles, discoloration and loss of skin elasticity. -
Smoking
Smoking releases free radicals that damage collagen fibers, leading to faster skin aging and weakened connective tissue. In addition, nicotine restricts blood flow, making it difficult to deliver essential nutrients to the skin and tissues. -
Improper diet
A lack of key nutrients such as vitamin C, zinc, copper and amino acids (glycine, proline), which are essential for collagen production, can lead to a decline in collagen levels. In a diet low in protein, fruits and vegetables, the body does not have enough resources to produce collagen at adequate levels. -
Oxidative stress
Excess free radicals, caused by factors such as air pollution, stress and poor eating habits, cause damage to cells and collagen fibers, which accelerates the aging process and weakens the body's regenerative abilities.
Effects of collagen deficiency - what can happen to your body?
Collagen deficiency has many negative consequences that affect various parts of the body. Consider how a lack of collagen can affect your health?
-
Skin - loss of elasticity and signs of aging
Collagen is a key element for skin health. It is responsible for its firmness, hydration and elasticity. When collagen levels decline, the skin begins to age - wrinkles appear, the skin becomes more flabby and loses its youthful glow. This process is the result of the body's reduced ability to produce new collagen fibers, resulting in a loss of skin integrity.
Reduced collagen also affects slower wound healing, greater susceptibility to injury and a greater risk of scarring. The skin becomes thinner, drier, and stretch marks and cellulite become more visible. -
Joints and bones - pain, stiffness and osteoarthritis
Collagen is crucial for joint and bone health. Articular cartilage, which protects bones from friction, consists mainly of type II collagen. When its levels drop, cartilage becomes thinner, leading to pain, stiffness and an increased risk of joint damage. Collagen deficiency can lead to the development of degenerative diseases such as osteoarthrosis.
In bones, collagen acts as an elastic matrix that gives them strength. Its lack leads to weaker bones, increasing the risk of osteoporosis and fractures, especially in the elderly.

Muscle problems and musculoskeletal ailments
Have you noticed that your muscles are becoming stiff and more prone to injury? Collagen plays a key role in the structure of muscles and tendons, so its deficiency directly affects their function. Lack of sufficient collagen can lead to weakened muscles, making them less resilient and faster to fatigue after exercise.
Collagen deficiency also results in the formation of trigger points - painful areas in the muscles that become tense and cause discomfort. These areas of tension can lead to chronic pain, limiting freedom of movement. What's more, collagen is essential for muscle recovery after intense exercise, so a deficiency delays the recovery process and increases the risk of injury.
Sciatica sufferers may also notice an increase in symptoms. Collagen plays an important role in maintaining the health of intervertebral discs, which cushion spinal movements. A lack of collagen can lead to a weakening of these structures, which increases the risk of sciatic nerve compression pain. -
Blood vessels and heart - a threat to cardiovascular health
Did you know that collagen is also found in the walls of blood vessels? Type III collagen provides elasticity and strength to the vessels, allowing them to function properly. Collagen deficiency weakens blood vessels, increasing the risk of ruptures, aneurysms and other cardiovascular problems.
Reduced collagen in the vessels can lead to atherosclerosis, as blood vessels become stiff and less flexible. This, in turn, increases the risk of heart attack, stroke and other serious health problems. -
Eye and internal organ problems
Collagen also has an important function in the cornea of the eye, maintaining its shape and clarity. Collagen deficiency can lead to vision problems such as corneal degeneration, which threatens your ability to see.
Collagen also provides structural support for internal organs such as the liver, lungs and kidneys. A lack of it weakens these structures, which can lead to organ dysfunction and an increased risk of disease.
Benefits of collagen supplementation - is it worth it?
Collagen supplementation may prove to be a key solution for people who suffer from the effects of collagen deficiency. Many scientific studies confirm that collagen supplementation has widespread health benefits. Here's how collagen supplementation works and what its benefits are:
-
Improving skin elasticity and hydration
Using hydrolyzed collagen can improve skin hydration, increase elasticity and reduce the appearance of wrinkles. Collagen also promotes skin regeneration, which can speed up wound healing and reduce the appearance of scars. Regular supplementation can help keep skin looking young for longer. -
Supporting joint and bone health
Supplementation with collagen, especially type II, helps rebuild joint cartilage and supports bone health. It works particularly well for people suffering from osteoarthrosis, reducing joint pain and improving joint flexibility. Studies show that people taking hydrolyzed collagen can experience significant improvements in mobility and reduced joint pain. -
Cardiovascular protection
Collagen also supports the health of blood vessels, improving their elasticity and strength. This reduces the risk of cardiovascular diseases such as atherosclerosis, heart attack and stroke. -
Strengthening hair and nails
Collagen deficiency can weaken the structure of hair and nails. Supplementation can help strengthen hair, increase hair volume and prevent nail brittleness. Collagen provides the building blocks needed to regenerate cells in these structures, which can improve their health and appearance.
Bottom line - why is collagen the key to health?
Collagen is the foundation for the health of skin, joints, bones, blood vessels, muscles and many other tissues in our bodies. A decline in its production, especially after the age of 25, leads to visible signs of aging and a weakened body. However, there are ways to counteract these changes. Collagen supplementation, proper diet, protecting skin from UV radiation and avoiding harmful habits can help support collagen production and prevent collagen deficiency.
Think about how you take care of your health - maybe it's time to support your body with the right habits and supplementation to help you stay healthy and youthful longer.
