Hydrolyzed collagen: benefits, effectiveness, and tips for choosing

Hydrolyzed collagen has become an essential dietary supplement for anyone looking 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 quickly absorbed and effectively utilized 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, accounting for 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 known as collagen peptides, results from a process called enzymatic hydrolysis. This technique involves cutting long collagen chains into smaller peptides, which are much more easily assimilated 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 quickly absorbed by the intestine and to circulate in the body to act directly at the level of 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 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 resistance.

• Type II : localized 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, bovine, porcine collagen… 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 similar 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.

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

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

Focus on hydrolyzed marine form

The hydrolyzed marine collagen comes from sustainably sourced fish and is treated by gentle enzymatic hydrolysis. It is rich in specific amino acids such as glycine, proline, and hydroxyproline, which are 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 nail and hair strength,

• 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 gradual decline in collagen levels in the dermis, which promotes the appearance of wrinkles, fine lines, and skin laxity. Hydrolyzed collagen promotes cell 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 an essential role in the regeneration of epidermal cells, which promotes a healthier, more radiant, and more resilient skin against external aggressions.

Keratin stimulation and hair growth

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

Nail strengthening and breakage reduction

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

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 of cartilage and connective tissues

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

Reduction of pain and improvement of mobility

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

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 most easily absorbed form.

Molecular weight, bioavailability and assimilation

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 formulas non-GMO, without controversial additives, without added sugars, 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...

• Liquid shots: quick absorption, portable format;

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

Dosage and ideal time for taking

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.
