Collagen effectiveness depends on peptide bioavailability and diet

The effectiveness of collagen supplements depends heavily on product quality and formulation rather than just the amount of collagen listed on the label. According to Rocío Lajarín, CEO of Alma Secret and a Doctor of Pharmacy, collagen in its natural state is too large for the body to absorb effectively.

To be useful, collagen must undergo hydrolysis to be converted into peptides. These smaller chains are capable of crossing the intestinal barrier and entering the bloodstream. Lajarín emphasizes that bioavailability—the ability of the body to actually use the substance—is the most critical indicator of success.

Beyond supplements, certain foods can support the body's natural collagen production. Fruits such as avocado, oranges, guava, berries, and mango are noted for being rich in vitamins C and A, zinc, and copper, which are essential for stimulating collagen synthesis and maintaining skin, joint, and bone health.
