The benefits of collagen

Collagen plays a key role in the normal functioning of our body. Collagen has many benefits. However, its production decreases with age. What should we think about collagen peptide supplements? What is their usefulness according to current scientific data ?

What is the collagen molecule?

Collagen is the most abundant protein in our body, accounting for approximately 30% to 35% of total protein. It is an important component for maintaining the structure of many tissues. Present in the skin, bones, tendons, ligaments and cartilage, collagen is essential for maintaining the structure, resilience and integrity of these tissues.

The unique structure of collagen is characterised by a triple helix. This is a configuration of three polypeptide chains wound around each other. This particular configuration is what gives collagen its exceptional strength and elasticity properties. Each chain is rich in glycine, proline, and hydroxyproline, three amino acids that play a crucial role in the stability and formation of the triple helix.

What is collagen used for? What are its benefits for the body?

Collagen is a vital protein that plays several key roles in maintaining the health and structure of the body's connective tissues. Here are its main roles:

• Benefits of collagen for joints and muscles: Collagen is one of the main essential components of joints and bones, ensuring tissue cohesion and elasticity. Its loss can cause discomfort. Similarly, through its protein content, it helps maintain muscle mass.
• Benefits of collagen for the skin: Collagen plays an essential role in skin firmness and elasticity. As we age, natural collagen production decreases, which can lead to a loss of firmness and the appearance of wrinkles and fine lines. Collagen supplementation, particularly in the form of hydrolysate, can help improve these signs of skin ageing by strengthening the skin's structure.
• Benefits of collagen for hair: Some studies suggest that collagen supplementation may improve the overall appearance of hair. As collagen is present in the connective tissue of the scalp, it may help to strengthen hair follicles and prevent hair breakage.

What happens with age?

As we age, natural collagen production slows down, leading to a decrease in connective tissue density. This manifests itself in signs of skin ageing (the appearance of wrinkles) and reduced mobility. This reduction can affect overall quality of life, hence the importance of supporting collagen production through a varied and balanced diet and healthy lifestyle.

What are the specific effects of marine collagen?

Marine collagen, often extracted from fish skin and scales, is known for its good assimilation, thanks to its hydrolysed form. Hydrolysed collagen is a form of collagen that has been broken down into smaller peptides. This hydrolysis is achieved through an enzymatic process that breaks down long protein chains into shorter segments. Thanks to its smaller size, hydrolysed collagen is more easily absorbed by the body than non-hydrolysed collagen.

Studies suggest that marine collagen may play a role in maintaining the appearance of the skin and in joint and muscle comfort. However, the effects of collagen-based dietary supplements can vary considerably from one person to another, depending on age, gender, skin type, lifestyle, and even genetics.

Where can collagen be found? In what types of products?

Collagen is mainly synthesised by our bodies, but it is also available in various foods and products:

• Meat and fish: Collagen is found in abundance in animal connective tissue. Red meat, chicken and fish are particularly rich sources, especially the less tender parts and cuts that contain bones, skin and cartilage. For example, chicken wings and thighs, as well as pig's trotters, are particularly rich in collagen.
• Meat broths: Preparing a broth by slowly simmering animal bones, skin and cartilage extracts collagen, which is transformed into gelatin that can be easily absorbed by our bodies. Homemade bone broths are excellent sources of natural collagen.

It is important to note that there is no such thing as natural vegan collagen. However, certain plant-based products can support the body's production of collagen. Vitamin C is essential for its synthesis.

What is the natural food richest in collagen?

Bone broth, prepared by simmering bones and cartilage for a long time, is an exceptional source of natural collagen. This type of preparation extracts collagen from connective tissue, transforming it into a more easily assimilable form.

Dietary supplements: is it useful to take collagen?

Collagen-based dietary supplements have become very popular, particularly for their potential effects on skin and joint health. Generally considered a concentrated source of active ingredients, collagen supplements can bring about noticeable improvements in skin firmness and elasticity, contributing to a more youthful appearance. Collagen is an essential component for joints.

Incorporating collagen supplements into your diet can be a useful strategy, but it should never replace the basics of a varied and balanced diet, rich in essential vitamins and minerals. It is also important to remember that dietary supplements are not medicines and should not be used as such.

Before starting a collagen supplement regimen, it is recommended to consult a healthcare professional. This is particularly important for individuals taking long-term medications, as there may be interactions or contraindications.

While collagen supplementation may offer certain health benefits in adulthood, a balanced and well-informed approach is essential. Combining supplements with a healthy diet and an active lifestyle (daily physical activity) is the best way to maximise the potential benefits for health and well-being.
