The benefits of collagen

What is collagen?

Collagen is the most abundant protein in the human body, making up about 30% of total proteins. It plays a vital role in the structure and strength of connective tissues like skin, bones, tendons, ligaments, and blood vessels.

There are different types of collagen, with the main ones being:

  • Type I Collagen: found in skin, tendons, and bones, it provides firmness and strength to tissues.

  • Type II Collagen: specific to cartilage, it supports joint health.

  • Type III Collagen: found in skin, muscles, and blood vessels, it provides suppleness and elasticity.

As we age, collagen production decreases, leading to visible signs of aging and joint discomfort. Fortunately, various solutions exist to support its production and make up for this loss.

The benefits of collagen

1. Improved Skin and Anti-Aging Effects

Collagen helps with normal skin formation by ensuring its firmness, elasticity, and hydration. Its natural decline promotes the appearance of wrinkles and skin sagging. Several studies show that supplementing with collagen peptides visibly improves skin texture and hydration.

2. Joint Support and Pain Reduction

Type II collagen is essential for cartilage, which cushions impacts and maintains joint mobility. Regular intake of collagen hydrolysate can help reduce joint pain and improve joint flexibility, especially for athletes and people with osteoarthritis.

3. Stronger Bones

Bones are largely made up of collagen fibers, which give them their strength. A decrease in collagen can lead to bone weakening and increase the risk of fractures. Studies suggest that consuming collagen supplements could help improve bone density.

4. Improved Hair and Nails

Collagen plays a role in the growth and strength of hair and nails. Regular consumption can reduce nail breakage and make hair thicker and shinier.

Different Forms of Collagen and Their Absorption

Collagen Supplementation

Collagen supplementation is generally recommended in the form of collagen hydrolysate or collagen peptides, which have a low molecular weight and are easily absorbed by the body. Among the most popular sources is marine collagen, derived from fish, which offers excellent bioavailability.

Collagen Creams: Limited Effectiveness

Collagen creams are often promoted for their anti-aging effects. However, collagen is a large molecule that cannot cross the skin barrier and reach the dermis. Therefore, these creams primarily provide surface hydration but do not increase collagen production in the skin.

It is better to use peptide-rich creams that will stimulate the collagen naturally present in your skin.

Collagen Injections

Unlike creams, collagen injections are an effective alternative for filling wrinkles and restoring facial volume. They offer immediate visible results and stimulate natural collagen production.

Factors Influencing Collagen Production

Several factors can either boost or slow down collagen production:

  • Age: Collagen production decreases as you get older.

  • Diet: A sufficient intake of amino acids (glycine, proline) and vitamin C is essential.

  • Sun Exposure: UV rays break down the collagen in your skin.

  • Smoking and Alcohol: These speed up collagen loss.

  • Stress: Excess cortisol harms collagen production.

Conclusion

Collagen is a vital protein for healthy skin, joints, bones, and hair. As its production decreases with age, solutions like marine collagen or collagen peptide supplements can be beneficial. However, collagen creams have limited effectiveness due to the size of their molecules, while injections remain a more effective solution for visible results. To maintain good collagen levels, it's also essential to adopt a healthy lifestyle and a balanced diet.
