Hydrolyzed collagen: benefits, effectiveness, and tips for choosing

Hydrolyzed collagen is now established as an essential dietary supplement for all those who wish to improve the health of their skin, joints, hair, and nails. 

Thanks to its low molecular weight, it offers exceptional bioavailability, which means it is rapidly absorbed and efficiently used by the body.

Derived from an enzymatic process called hydrolysis, this "predigested" collagen is scientifically recognized for its multiple benefits. It provides a natural solution to preserve skin youthfulness, strengthen joint strength, and support the overall vitality of connective tissues.

What is hydrolysis?

Collagen is a major structural protein, representing about 30% of the total proteins in the body. It ensures the cohesion, strength, and elasticity of tissues such as skin, bones, tendons, ligaments, hair, and nails.

Hydrolyzed collagen, also called collagen peptides, results from a process called enzymatic hydrolysis. This technique involves cutting long collagen chains into smaller peptides, which are much more easily absorbed by the body.

How does the hydrolysis process work?

Hydrolysis is carried out by specific enzymes that break the peptide bonds of native collagen, thereby reducing its average molecular weight to around 2,000 Da (Daltons). This reduced size allows the peptides to be more rapidly absorbed by the intestine and to circulate in the body to act directly at the target tissues.

Differences between native and hydrolyzed

Native collagen, in its raw form, is a large molecule that is difficult to digest and poorly absorbed. In contrast, hydrolyzed collagen comes in the form of short peptides, highly digestible and scientifically validated for their effects on the skin, joints, and hair.

Type I, II, and III Collagen: What Are the Differences?

Collagen comes in several types, each having a specific function:

• Type I: the most abundant, present in the skin, bones, tendons. It is responsible for firmness, density, and skin strength.

• Type II: located in the cartilage, it plays a central role in joint health.

• Type III: present in blood vessels, muscles, and organs, often in synergy with type I, it contributes to tissue elasticity.

Hydrolyzed type I collagen is the most used in nutricosmetics for its effects on the skin, hair, and nails, while type II is targeted for joint comfort.

Marine collagen, bovine, porcine... which one to choose?

The choice of source depends on your goals and preferences:

• Hydrolyzed marine collagen: extracted from fish skin or bones, it offers excellent bioavailability and a structure close to human collagen. It is the ideal choice for skin beauty.

• Bovine collagen: derived from beef cartilage, it is rich in type I and III. Recommended for joints and skin.

• Porcine collagen: composition similar to human collagen, often used in mixed formulas.

For optimal effectiveness and high tolerance, hydrolyzed marine collagen remains the premium reference. Discover which collagen to choose.

Focus on hydrolyzed marine collagen

The hydrolyzed marine collagen comes from fish sourced sustainably and is processed by gentle enzymatic hydrolysis. It is rich in specific amino acids such as glycine, proline, and hydroxyproline, essential for endogenous collagen synthesis.

✔️ Its clinically proven benefits :

• Improvement of firmness and elasticity of the skin,

• Reduction of wrinkles and fine lines,

• Strengthening of nails and hair durability,

• Support for joint flexibility.

Improvement of elasticity and firmness

Hydrolyzed collagen stimulates the natural production of new collagen and elastin fibers, two key components of the dermal structure. This stimulation helps to firm the skin, preserve its suppleness, and maintain a youthful and toned appearance. Thanks to its high bioavailability, hydrolyzed collagen works deeply, where the skin needs it most.

Reduction of wrinkles and skin aging

The natural aging process causes a progressive decrease in collagen levels in the dermis, which promotes the appearance of winkles, fine lines, and skin sagging. Hydrolyzed collagen promotes cellular regeneration and increases the density of the dermal matrix, thereby helping to smooth existing wrinkles and slow down skin aging.

Effect on hydration and cellular regeneration

By strengthening the skin barrier and increasing the skin's ability to retain water, hydrolyzed collagen contributes to better hydration. It also plays a key role in epidermal cell regeneration, which promotes healthier, more radiant skin that is more resistant to external aggressions.

Stimulation of keratin and hair growth

Hydrolyzed collagen provides key amino acids — glycine, proline, and hydroxyproline — necessary for keratin synthesis, the main protein of hair. It thus supports denser hair growth, improves natural shine, and reduces breakage.

For more information, see our article on the benefits of collagen for hair.

Nail strengthening and breakage reduction

Hydrolyzed collagen provides the amino acids necessary for the growth and strength of nails, thereby reducing the risk of breakage and fragility.

The role of collagen in overall beauty ✨

Beyond the skin, hair, and nails, hydrolyzed collagen contributes to the overall balance of the body. It promotes detoxification, supports blood circulation, and can even improve muscle tone. Beautiful skin starts with a strong and healthy internal structure.

Support for cartilage and connective tissues

Collagen is a key component of articular cartilage. By providing the peptides necessary for its regeneration, hydrolyzed collagen helps to strengthen joint structures, improve flexibility, and limit wear related to age or physical activity.

For more information, see our blog on collagen and joints.

Pain reduction and improved mobility

Thanks to its indirect anti-inflammatory action and its role in tissue repair, hydrolyzed collagen helps to relieve joint pain, especially in cases of osteoarthritis, and to restore better daily mobility.

Bone regeneration and prevention of osteoarthritis

In synergy with calcium, vitamin D, and vitamin C, hydrolyzed collagen stimulates the activity of osteoblasts (cells responsible for bone formation) and preserves bone mineral density, thus contributing to preventing osteoporosis and the progression of osteoarthritis.

Quality, traceability and origin

A good collagen starts with a quality raw material, sourced from sustainable, traceable, and ideally marine sources. Hydrolyzed marine collagen, derived from wild fish, is now recognized as the purest and best absorbed form.

Molecular weight, bioavailability, and absorption

The low molecular weight of collagen peptides (ideally < 2,000 Da) is a key factor for optimal intestinal absorption. The smaller the peptides, the more quickly they are available to nourish the skin, joints, bones, and hair.

Purity criteria and absence of additives

Choose non-GMO, free from controversial additives, no added sugars formulas, and ideally clinically tested. At D-LAB NUTRICOSMETICS, collagen-based products meet these demanding standards for visible and lasting results.

Available formats: powder, capsules, liquid...

Hydrolyzed collagen is available in several formats:

• Capsules / tablets: convenient for a hassle-free routine;

• Liquid shots: rapid absorption, portable format;

• Powders: to be diluted in drinks or recipes for a pleasure cure.

Dosage and ideal time for intake

For optimal effectiveness, it is recommended to consume between 2 and 10g of hydrolyzed collagen per day, on an empty stomach in the morning or in the evening before bed. A minimum 3-month course is generally necessary to see visible results on the skin or joints.
