I’m sure this is not the first time you hear the word collagen. A friend or a relative already use it or you’ve just seen in at the pharmacy or at the supermarket, but what is collagen for?

Collagen is an essential protein for our body since it makes up to 25% of the total of our protein mass. It’s the main component of our bones and skin, and is also one of the building block of our joints, tendons, hair and muscles. We’re talking about one of the fundamental elements for a normal function of our body.

Its main role is providing strength and flexibility to our body which allows us to stand and move, for that matter.


Our body produces collagen naturally. However, after hitting 30 and especially after turning 40 our body gradually starts losing its ability to generate it by itself. One of the consequences of not producing collagen is related to ageing, but not only on the outside, it also happens at the inner level:

  • Difficulty to move
  • Joint swelling
  • Losing skin firmness
  • Appearance of wrinkles
  • Hair loss


Through our diet we can increase collagen synthesis. Foods rich in vitamin C, silicon and sulfur boost the synthesis of collagen so their ingestion is always beneficial. This list includes foods that support collagen synthesis:

  • Foods rich in vitamin C: red pepper, citrus fruits, green leaf vegetable, red berries…
  • Foods rich in sulfur: cucumber, garlic, onion, olives, celery
  • Foods rich in silicon: oats, banana, raisins, carrots, spinach

However, in some cases, including these foods in our diet does not guarantee collagen synthesis so a collagen based supplement becomes necessary.


An efficient way to slowing down the decrease of this structural component and to avoid later health conditions is taking a collagen supplement. Especially after hitting 40.

Generally, 10g per day is normally recommended. The most widely known is hydrolyzed collagen.

They may be made from two different sources:

  • From mammals: bovine
  • From the sea: derivatives of fish and seaweeds

In the market are available supplements focused on specific goals:

  • Joint health maintenance
  • Improvement of joint injury symptoms (sports)
  • Beauty
