Protesol D

What is Collagen?

Collagen is a fibrous protein that is found in the skin, bones, muscles, tendons, and ligaments of all mammals. It is the most abundant protein in the human body, and accounts for approximately 30% of all the total protein in our bodies.

Collagen is essential for ensuring the healthy structure and function of the body’s connective tissues. It is responsible for maintaining elasticity and resilience in the skin, hair, nails, bones and muscles. It is also important for healthy joints and cartilage.

As we age, collagen production declines, and this leads to wrinkles, less supple skin, weak bones, and the deterioration of cartilage. To counter this process many people take collagen supplements to improve the health and appearance of their skin, hair, nails, as well as to strengthen their joints.

Juncà Gelatines manufactures Protesol D, this dietary collagen hydrolysate is characterised by its organoleptic neutrality, and extremely high levels of microbiological purity and quality

This product is intended for human consumption, it is obtained from the enzymatic hydrolysis of collagen from skin of animal origin. Its 92% protein content comes in a format that is easy to digest and assimilate by the human body. Protesol D contains 18 amino acids, among which glycine, proline and hydroxyproline account for approximately 50% of its total amino acid content.

The Main Benefits of Collagen


Numerous clinical and pre-clinical studies have confirmed that a daily intake of hydrolysed collagen provides both regenerative and preventative effects on joint cartilage.
This is due to the fact that it naturally stimulates cartilage production at a cellular level.


A daily intake of 10 g of hydrolysed collagen may lead to a significant increase in bone mass, while reducing the risk of bone fractures for osteoporosis sufferers.

Hydrolysed collagen is a highly versatile nutritional supplement that is used in sports drinks, functional drinks, cereal bars and specialised recipes due to its physical qualities. It is also especially useful for dietary preparations and drinks with a high nutritional value.


Natural collagen peptides are an important ingredient in today’s skin care products. This natural, biological cosmetic ingredient is isolated and purified using non-aggressive extraction methods (mild enzymatic degradation). It is dermo-compatible and contaminant-free.

Thanks to its ability to form a film, it contributes to achieving a smoother and softer skin. The protective function of hydrolysed collagen is especially important in shower and bath products: not only does it substantially reduce the skin and mucous membrane irritation caused by conventional anionic surfactants, it also leaves the skin smoother and prevents it from drying out.

Native collagen with a high molecular weight has excellent moisturising properties that facilitate its topical use. This factor, combined with the fact that it is suitable for all skin types, has made it a commonly-used ingredient in creams and lotions. Collagen has been proven to improve skin hydration and texture, while it also limits wrinkle formation and depth.


Hydrolysed collagen supplementation helps makes brittle, dull nails strong and shiny again.

Protein hydrolysates isolated from collagen are a highly-valued ingredient in hair-care products due to their affinity with keratin. Their film-forming ability lends a glossy smoothness to the hair and makes it easier to work with, especially if chemical treatments have been applied beforehand. Proteins have an important protective effect on hair structure in perms and tints.

Adding protein hydrolysates to colouring sprays and dyes helps the hair to absorb colour more evenly, especially with natural dyes, where better absorption and more intense colouration have been observed. In those products applied without final rinsing, protein hydrolysates provide a clearly perceptible natural conditioning effect.
