The Sustained Effects of Bioactive Collagen Peptides on Skin Health: A Randomized, Double-Blind, Placebo-Controlled Clinical Study.

ABSTRACT:

Introduction

Collagen is a fundamental component of the skin's extracellular matrix, yet its low oral bioavailability raises questions about its efficacy in improving skin health. Bioactive collagen peptides (BCP), as hydrolyzed forms of collagen, offer enhanced absorption and functionality. However, evidence regarding their sustained effects and the impact of molecular weight distribution is still limited.

Aim

To evaluate the long-term effects of BCP supplementation on skin hydration, elasticity, and dermal structure, and to explore the relationship between molecular properties of BCP and skin outcomes.

Methods

A randomized, double-blind, placebo-controlled trial was conducted involving 77 healthy female participants aged. Subjects received either 5000 mg/day of BCP
