Collagen is a protein found in our skin and joints. Its production by our bodies naturally decreases with age, so it's advisable to take it as a dietary supplement. Its structural role in the body is enhanced when the collagen consumed is of marine origin and hydrolyzed, as this guarantees the internal production of type I and II collagen and optimizes its absorption. Magnesium works synergistically with this protein, boosting its beneficial effects by contributing to the normal functioning of the nervous system and muscles, and helping to reduce tiredness and fatigue.
