What is collagen and what are its benefits? Know all the science says

Collagen is the structural protein that gives our skin its elasticity and also keeps it firm. As a person ages, collagen levels decrease, causing the skin to wrinkle and sag. Under the premise of keeping the skin looking and feeling healthy, many collagen-based products (capsules, drinks, and powder) have gained space in the market. But what does the science say about these supplements?

According to an article by Annals of MedicineThere are 28 types of collagen, each classified according to its amino acid composition. About 90% of the body’s collagen is type 1, found in the skin, tendons, internal organs, and organic parts of bone.

Type 2 is found in cartilage, and type 3 is found in bone marrow and lymphoid tissue. In contrast, Type 4 is found in thin layers that encapsulate most fabrics. Another common collagen is type 5, found in hair and cell surfaces.

What is collagen?

Studies have already highlighted the benefits of collagen for bone and joint health. According to a study published in International OrthopedicsSupplements can help treat symptoms of arthritis, for example. Researchers have highlighted the surgical introduction of collagen into the joints in search of a promising treatment for osteoarthritis, incl.

Scientific Journal Dental Materials Journal It indicates that collagen peptides derived from the skin, bones, and scales of fish help regulate the proliferation of bone growth cells, preventing bones from easily breaking.

However, even scientific studies on collagen show differences: according to an article in the journal Mature supplement use Postmenopausal women with low bone mineral density did not show significant improvements in their bone structure.

However, a study published in Online Biomedical Engineering He says that when collagen is applied to the skin, it can help heal and prevent infections. Researchers published in International Journal of Dermatology A meta-analysis of 19 studies unanimously noted the benefits of collagen supplementation in terms of hydrating the skin and preventing sagging and wrinkles.

However, many people seek collagen because they believe that supplements can prevent hair loss. There is a dearth of studies proving this relationship, and many researchers don’t believe it has any effect.

Is it true that there is no point in eating collagen?

While collagen swears by scientists, the consensus is that there are benefits. The point is that these supplements must go along with a healthy lifestyle. In addition, experts recommend paying attention to which product to use: it needs good absorption of the active ingredients.

Thus, the most recommended is a supplement containing bioactive collagen peptides, able to partially survive the digestion process without decomposition.
