Marine collagen

What is marine collagen?

Marine collagen is a protein extracted mainly from the scales and skins of fish such as salmon, tilapia and cod, with a structure similar to that of naturally occurring collagen in humans. As a result, it has a very good bioavailability, up to 50% more effective than other animal collagens. Marine collagen has beneficial effects on various aspects of health, which we will learn about later in this article.

Are marine collagen and fish collagen the same thing?

Many of us may be confused about collagen terminology, especially when terms such as marine and fish collagen come up. In theory, both types of collagen originate from marine sources and are used interchangeably. Both fish collagen and what is generally referred to as marine collagen have been shown to have remarkable benefits for skin health, joint health, and overall body health. Therefore, although the terminology may cause some confusion, both names refer to the same beneficial ingredient of marine origin.

Marine collagen – properties and characteristics

Marine collagen, also known as fish collagen, is a protein with excellent absorption and bioavailability, making it considered the most effective of all collagens derived from animals. Its unique properties are due to the presence of key amino acids such as proline and glycine, which play an important role in many bodily functions. Fish collagen is distinguished by the rarer chemical bonds between fibres compared to bovine or porcine collagen, which translates into higher solubility of this protein. The rare bonds between fibres make fish collagen ideal for its structural function, maintaining the integrity of tissues and organs. It is a key element that not only fills the space between cells, but also imparts hardness, elasticity, stiffness and resilience. Fish collagen mainly contains type I collagen. This type of collagen is present in virtually all areas of the body[1], with the exception of cartilage tissue. Due to fish collagen’s similarity to human collagen, it shows a high level of effectiveness, being a valued ingredient in many food products, dietary supplements and cosmetics.

How does marine collagen work? What are the advantages and disadvantages?

Marine collagen, like any product, despite its many advantages, also has a few drawbacks that are worth mentioning. Let’s explore both the good and the poor features of fish collagen.

Pros:

1. Improves skin condition: fish collagen is an essential building block of the skin, improving firmness, elasticity and hydration. It reduces the appearance of wrinkles and minimises the effects of skin ageing[2].

2. Skin regeneration: collagen has a strong restorative effect, accelerating wound healing and soothing scars[3]. Supplementation supports the regenerative processes of the skin, helping to maintain its healthy state.

3. Effects on hair and nails: fish collagen, as an integral component of keratin, strengthens hair structure. It prevents hair breakage, giving it density, shine and elasticity. It also helps to maintain strong, fracture-resistant nails. Results from a 2017 study on women showed reduced nail brittleness by 42% and increased growth rates by 12% after regular supplementation with fish collagen.

4. Support for joint health: increases the elasticity of the connective tissue in the joints, improving mobility. It also regenerates joint cartilage, which is important for osteoarthritis.

Disadvantages:

1. Potential allergic reactions: people who are allergic to marine-derived ingredients, such as fish, may experience allergic reactions after consuming marine collagen. Therefore, supplementation should be used with caution, especially by those with hypersensitivity to marine products.
2. Possible specific taste and odour: some marine collagen supplements may have a specific taste or odour, which may be a problem for some people. This aspect may affect the acceptance of the product, especially if the consumer has high expectations in terms of taste.
3. Possible specific taste and odour: some marine collagen supplements may have a specific taste or odour, which may be a problem for some people. This aspect may affect the acceptance of the product, especially if the consumer has high expectations in terms of taste.

For whom is marine collagen?

Marine collagen can be beneficial for different groups of people, especially because of its comprehensive health benefits.

Here are some groups of people who may benefit from marine collagen supplementation:

• Skin-caring people: marine collagen is known for its positive effects on skin health. It acts as a natural building block of the skin, improving its firmness, elasticity and hydration. A 2023 scientific study on more than 1,700 patients showed the positive effects of collagen hydrolysate on skin elasticity and hydration[4].
• People with joint problems: fish collagen can support joint, cartilage and ligament health. It is beneficial for those experiencing joint pain, as well as those who want to prevent joint degeneration[5].
• Those wishing to strengthen hair and nails: marine collagen components such as glycine, proline and hydroxyproline are important for hair and nail health. Collagen supplementation can help to increase their strength, elasticity and condition[6].
• Physically active people: people with active lifestyles, especially those involved in intense training, can benefit from the regenerative properties of collagen. It helps to rebuild connective tissue, promoting recovery after intense exercise[7].
• Those concerned about healthy bones: collagen plays an important role in bone health, supporting bone structure and flexibility. People who want to maintain strong and healthy bones, especially in older age, can benefit from marine collagen supplementation.
• People going through the ageing process: as we age, the body’s production of natural collagen decreases, which can lead to a loss of skin firmness, the appearance of wrinkles and joint problems. Supplementation with marine collagen can help to combat the signs of ageing[8].

Is it worth supplementing with marine collagen?

As the main ingredient responsible for the elasticity of the skin, marine collagen is a versatile solution for anyone wishing to maintain a youthful appearance and look and feel good about themselves. Its anti-ageing properties, effect on skin hydration and tissue regeneration make it a valuable part of daily skincare. Further aspects that speak in favour of supplementation are support for joint health, strengthening of hair and nails, as well as anti-ageing effects. The valuable effects on the outward appearance and condition of the body mean that marine collagen supplementation can be a valuable support for those who wish to maintain a healthy and attractive appearance for longer.

In addition, marine collagen is available in several forms, such as:

Collagen powder

Collagen powder is isolated collagen molecules that can be easily added to a variety of drinks or foods. It is colourless and characterised by its versatility of use. Thus, collagen powder can be conveniently consumed according to individual preferences.

Drinking collagen

Drinkable collagen, on the other hand, are ready-made drinks or shots containing dissolved collagen molecules. They are often available in a variety of flavours and formulations, making them easy to consume without preparation.

Marine collagen news summary

From the article, you already know that marine collagen is synonymous with fish collagen, being a valuable source of protein that can provide numerous benefits for skin, joint, hair and nail health. Due to its high bioavailability and similarity to human collagen, it is easily absorbed in the body. Fish collagen supplementation in the form of collagen drink or powder can support skin elasticity, joint regeneration, and improve hair and nail health.
