The Active Ingredient Is: L-Proline

L-Proline is basically an amino acid used by the body as a building block for proteins, including collagen, which helps support connective tissues in the body.

This form is the free amino acid L-Proline, which participates in collagen synthesis and helps contribute to the structural integrity of tissues like skin, cartilage, tendons and ligaments.

What Does L-Proline Really Do?

L-Proline serves as a precursor to hydroxyproline, an essential part of collagen’s triple-helix structure, thereby supporting collagen production and connective tissue health. This means this role aligns with research showing proline supports collagen formation and tissue repair processes, which underpin skin and joint structure.

Scientific research shows that proline contributes to collagen synthesis and tissue maintenance, with broader support for connective tissue health cited by experts at a university in related studies.
