COLLAGEN, an essential protein for our health, mobility and appearance 

Collagen

It is the most abundant and extended protein in our body.

This highly resistant and flexible molecule forms the structure of all tissues in the body, which provide protection and allow us to stand up and move.

It constitutes 70% of the cartilages’ dry weight, 20% of the bones, 85% of the tendons, 70% of the ligaments, 75% of skin and 6% of muscles, besides being the main component of the connective tissue, which covers and protects all our internal vital organs.

Collagen molecule

Causes that contribute to collagen loss
Over the years, the collagen in our body is lost and deteriorates naturally and progressively. From the age of 30 the first signs of ageing appear on the skin and, later, joint pain due to wear and tear, and loss of bone mass and decalcification, among others.
Age
Intense physical exercise has a high impact on muscles and joints, therefore, the loss and deterioration of collagen in these tissues increases. Likewise, injuries, frequent with the intensive practice of sport or exercise, weaken the collagenous tissues of muscles, joints and/or bones.
Sports or physical exercise
The decrease in hormone levels associated with menopause causes accelerated degradation and loss of collagen.
Menopause
Trauma can cause collagen fibres in the joints, muscles, and bones to break, so they can break down prematurely.
Traumatism
Being overweight produces an overload in the lower joints, which accelerates the wear of their collagen, so they deteriorate early, causing joint pain.
Overweight
Main consequences of collagen loss
Joint pain
Mass loss and bone decalcification producing fractures
Skin ageing
Muscle fatigue and pain
Physical ageing is mainly due to the loss and degradation of our collagen,

As time goes by, our collagen production is reduced and it gets deteriorated. From the age of 25 years old, we lose every year about 1.5% of this protein. Besides, intense physical exercise, as well as menopause or overweight, speeds up this process.

Hydrolysed collagen (bioactive collagen peptides)

Collagen is, exclusively, an animal protein. Found in animal tissues (native collagen), it is a very long and complex molecule, which cannot be used as a nutrient because our digestive system cannot digest it and, therefore, it cannot take advantage of it.

Collagen needs to become digestible and assimilable. For that, it is necessary to go through two processes:

Gelatinisation: Unroll of the triple-helix collagen molecule. This process, in which gelatine is obtained, usually takes place by chemical processes (alkali or powerful acids). However, for the manufacture of COLPROPUR D®, we only apply a physical treatment (heat).

Hydrolysis: Fragmentation of long collagen polypeptide chains (gelatine) in peptides (short chains) using enzymes like the ones in the human digestive system.

HYDROLYSED COLLAGEN is the result of this process. It is formed by bioactive collagen peptides, smaller molecules easier to be absorbed by our digestive system and, therefore, used as nutrients for our body.

Accurate scientific studies endorse that taking 10 grams of HYDROLYSED COLLAGEN daily, which is very assimilable, effectively reduces our collagen loss, delaying the ageing symptoms, helping prevent and treat illnesses related to this loss. HYDROLYSED COLLAGEN is the easiest and most effective way of supplementing our diet with assimilable collagen, it is a healthy life habit, essential after turning 40.
