What Is Collagen?

November 3, 2021

The  collagen is the most abundant protein in our body. As we age, the ability to synthesize it decreases and, in certain situations (overweight, excessive sports activity, etc.) wear and tear accelerates.

It is composed of amino acids, some specific such as glycine, proline, hydroxyproline and arginine, which in turn are made up of carbon, oxygen and hydrogen.

Collagen Contains Amino Acids It is made up of approximately 30% of the proteins within the body. These are tough, strong structures found in bones, tendons, and ligaments.

Where is Collagen found

Collagen is found exclusively in animals, especially in mammalian meat and connective tissues. It is a part of the connective tissue that in the skin helps in firmness, flexibility and the constant renewal of epithelial cells. It is also vital for skin elasticity.

Collagen is the main component of connective tissue, and is the most abundant protein in mammals, making up about 25% to 35% of the whole-body protein content.

It is also present in all tissues of the smooth muscle, blood vessels, digestive system, heart, gallbladder, kidneys and diaphragm waiting for the cells and tissues together. Collagen is even the largest component of hair and nails.

When the body begins to lack collagen, a series of changes take place: such as the appearance of wrinkles, sagging, loss of bone mass, joint discomfort and even the arrival of degenerative diseases.

Collagen as a Food Supplement

Hundreds of collagen products are currently sold as food supplements, commonly found in capsules, powders, etc. Hydrolyzed Collagen is a dietary supplement prepared from bovine bones and cartilage.

It is used to stimulate the production of collagen in the body, thus helping to improve the appearance of the skin, strengthen the joints, nails, bones and hair.

Collagen supplement is usually taken from the age of 30, at which point the body decreases its production.

However, the collagen supplement is also suitable for those who are very exposed to the sun, smoke or have an unhealthy diet, since these factors worsen the health of the skin and can affect the production of collagen in the body.

When it comes to ingesting collagen, professionals recommend that the daily dose be ten grams a day, no more. In addition, it is important to know what type of product to choose, especially since it should not include chemicals, sugars or additives.

However, before consuming collagen, you must consult your doctor so that he or she establishes the correct dose.

Collagen benefits

The main benefits of taking collagen as a supplement are:

  • It promotes the production of collagen naturally in the body.
  • Improves the resistance and strength of the joints, tendons and ligaments.
  • Improves blood pressure control.
  • Strengthens nails and hair.
  • Prevents bone loss and decalcification.
  • Improves the firmness and elasticity of the skin.


The consumption of collagen does not have important contraindications, since it is a natural product that the body assimilates easily.

However, the following people should avoid its consumption:

  • If you have an allergy to animal protein. It is important to always find out the source of the collagen.
  • If you suffer from hereditary phenylketonuria or intolerance to phenylalanine.

However, there are still divided options on the true functioning of collagen as a dietary supplement:

‘Collagen is a protein made of amino acids. When we ingest it, our body breaks it down into its smallest parts, which are no longer collagen » ─ José Miguel Mulet , tenured professor in the department of Biotechnology at the Polytechnic University of Valencia.


To replace collagen in the body is to incorporate it into our natural diet. To do this, we must recover recipes based on animal skins and bones to make broths. The most effective collagen foods are red meat, white meat, and gelatin.

It is important to highlight the foods that, directly or indirectly, stimulate and improve collagen production:

  • Foods rich in vitamin C: Green leafy vegetables, citrus fruits (and their peelings, if they are organic), red pepper, red fruits, etc.
  • Green tea: This miraculous medicinal drink has the ability to stimulate the production of collagen and elastin.
  • Foods rich in omega 3 fatty acids: Blue fish, walnuts, egg yolk, olive and flax oil, avocado, etc.
  • Sulfur-rich foods: Onion, olives, celery, cucumber.
