Myth: collagen supplements improve the condition of the skin and joints.

Collagen is an important

protein

, which provides strength and elasticity of the skin, blood vessels ligaments, tendons, and cartilage; bone tissue is built on the collagen matrix. However, collagen production decreases with age - after 20 years, we lose

about 1.5%

of collagen every year. Companies that produce various cosmetics and dietary supplements, it seems, this fact is only at hand. So, among the dietary supplements, which most often

are bought by

Russians, “vitamin complexes with collagen” are especially popular.

Theoretically, it makes sense to take collagen supplements to make up for the body’s natural losses, but in practice it’s completely different. The collagen from the capsules must be broken down into its constituent parts during digestion, enter the bloodstream, and then somehow and in some form end up in the skin. Yes, according to a few experiments on mice, collagen (taken orally) eventually got into the skin of animals, but in studies in humans it was not possible to track this effect.

There are studies that show: collagen supplements, unlike placebo, improve skin elasticity and hydration. Nevertheless, scientists are not in a hurry with conclusions.

Little data, they cover only a short period - people taking the supplements were monitored for several months. At the same time, the conflict of interests was not taken into account: part of the research was funded or managed by companies that sold collagen-containing products. In general, more extensive and independent research is needed to assess long-term prospects. Dermatologists have no reason to recommend collagen supplements to their patients to prolong skin youth.

In this case, doctors recommend taking into account the information that we, humanity, know about the aging mechanisms.

For example, the fact that ultraviolet rays stimulate collagen loss - yes, this is another call to use sunscreen. Or the fact that to maintain healthy skin it is important to eat well (read: varied) and give up cigarettes.
