Discover the Benefits of Marine Collagen

What is marine collagen?

Marine collagen, also known as fish collagen, is a structural protein obtained mainly from the skin, scales and bones of fish such as cod, salmon or tilapia. It consists mainly of type I collagen, the most abundant type of collagen in the human body, which is responsible for the strength and elasticity of skin, bones, tendons and ligaments.

Why is marine collagen so special?

Compared to other collagen sources such as beef or pork, marine collagen is characterized by its high bioavailability. Thanks to its lower molecular weight, it can be absorbed by the body up to 1.5 times more efficiently. This means that the amino acids it contains, such as glycine, proline and hydroxyproline, enter the bloodstream more quickly and support the body's own collagen production more effectively.

Sustainability and environmental friendliness

Another advantage of marine collagen is its sustainable production. It is produced from by-products of fish processing that would otherwise be considered waste. This not only reduces food waste, but also protects resources and the environment.

The difference between marine collagen and other types of collagen

Origin and composition

Marine collagen, also known as fish collagen, is obtained from the skin, scales and bones of fish such as cod or salmon. It consists mainly of type I collagen, which is responsible for the strength and elasticity of skin, bones and tendons. In comparison, bovine collagen comes from cattle and contains both type I and type III collagen, making it more versatile for supporting skin, joints and muscles.

Bioavailability and absorption

A key advantage of marine collagen is its high bioavailability. Due to its lower molecular weight, it can be absorbed by the body up to 1.5 times more efficiently than collagen from cattle or pigs. This means that the amino acids enter the bloodstream more quickly and support the body's own collagen production more effectively.

Sustainability and environmental friendliness

Marine collagen is made from by-products of fish processing that would otherwise be considered waste. This reduces food waste and conserves resources, making it a more environmentally friendly option compared to collagen from agricultural sources.

Benefits of marine collagen for skin health

Promotion of youthful and radiant skin

As we age, our body's natural collagen production decreases, leading to fine lines, wrinkles and sagging skin. Incorporating marine collagen into your daily diet can increase collagen levels, leading to improved skin elasticity and hydration. Studies have shown that marine collagen can reduce the signs of aging, such as wrinkles and dryness.

Support the production of important skin proteins

Fish collagen supports the production of other important proteins in the skin, such as elastin and fibrillin, which are responsible for maintaining the skin's firmness and suppleness. By stimulating the synthesis of these proteins, marine collagen can help to improve overall skin texture and reduce the appearance of scars and stretch marks.

Benefits of marine collagen for joint health

Support for cartilage regeneration

As we age, the cartilage in our joints begins to break down, which can lead to joint pain, stiffness and reduced mobility. Marine collagen provides essential amino acids such as glycine and proline, which serve as building blocks for the repair and regeneration of cartilage. This helps to maintain the integrity and flexibility of joints and reduce the risk of conditions such as osteoarthritis.

Scientifically proven effect on joint pain

Studies have shown that supplementation with marine collagen can relieve joint pain and improve joint function. In a randomized controlled trial, participants reported a significant reduction in knee pain during physical activity after taking specific collagen peptides for 12 weeks. The researchers found that the reduction in pain was confirmed both subjectively by the participants and objectively by medical examinations.

Improvement of joint function in active adults

Marine collagen can be particularly beneficial for athletes and active people. A study with young, physically active adults showed that the daily intake of 5 g of specific collagen peptides over 12 weeks led to a significant reduction in exercise-induced knee pain. The participants reported improved joint function and less discomfort during exercise.

How fish collagen can improve the health of hair and nails

Promotion of healthy hair growth

Fish collagen is rich in amino acids such as proline and glycine, which are essential for the production of keratin - the main component of our hair. By providing these building blocks, marine collagen helps to strengthen hair follicles, promote hair growth and improve the overall structure of the hair. In one study, women with thinning hair reported a 32% increase in hair volume and a 39% reduction in hair loss after taking marine collagen for six months.

Strengthening brittle nails

Our nails consist mainly of keratin, the production of which is supported by the amino acids in collagen. Regular intake of marine collagen can strengthen nail structure, reduce brittleness and promote growth. A clinical study showed that participants experienced a 42% decrease in nail breakage and a 24% increase in nail growth rate after 24 weeks of daily intake of collagen peptides.

Improvement of the general appearance

In addition to structural strengthening, the moisturizing properties of marine collagen help hair appear shinier and nails smoother. This leads to an overall healthier and more well-groomed appearance.

Scientific studies on marine collagen

Amino acid profile and collagen synthesis

Marine collagen is rich in essential amino acids such as glycine, proline and hydroxyproline, which play a central role in collagen synthesis. These amino acids promote the production of new collagen fibers, which helps to improve skin structure, joint health and general body functions.

Clinical studies and health benefits

Numerous studies have investigated the positive effects of marine collagen on various aspects of health:

✅ Skin health: A randomized, placebo-controlled study showed that the daily intake of 10 g of hydrolyzed fish collagen over 12 weeks led to a significant reduction in facial wrinkles and an improvement in skin elasticity, hydration and firmness.

✅ Joint function: Studies suggest that marine collagen peptides promote the regeneration of cartilage tissue and have anti-inflammatory properties, which may help to relieve joint pain and improve mobility.

✅ Hair and nail health: Regular intake of marine collagen has been associated with an improvement in hair thickness and density and a reduction in nail brittleness.

Bioavailability and absorption

An outstanding advantage of marine collagen is its high bioavailability. Due to its lower molecular weight, it is efficiently absorbed and utilized by the body. Hydrolyzed marine collagen achieves an absorption rate of up to 90%, making it an effective supplement for supporting skin and joint health.

How to incorporate marine collagen into your everyday life
