See the scientific wording

Daily consumption of 5.0 grams of either standard or fermented collagen peptides is well-tolerated and safe for healthy adults over a three-month duration, with clinical monitoring revealing no adverse events, significant alterations in body composition, or meaningful changes in baseline skin hydration and oil levels. This safety profile supports the short-term use of collagen peptide supplements for cosmetic skin benefits without systemic health risks or interference with normal skin barrier function.

What the research says

1 study
  1. Study: Effect of Reducing Pigmentation by Collagen Peptide Intake: A Randomized, Double-Blind, Placebo-Controlled Study

    The study explicitly monitored for adverse events and measured physiological parameters including body weight, BMI, and skin hydration/oil content. The absence of reported side effects and lack of significant changes in these baseline metrics confirm the short-term safety and non-disruptive nature of the supplement.
