Description
1 study reviewed
In plain English

Taking 2.5 grams of low-molecular-weight collagen peptides daily for six weeks does not cause adverse events in healthy women aged 30 to 65.

See the scientific wording

A daily dose of 2.5 grams of low-molecular-weight collagen peptides is well tolerated and causes no adverse events in healthy women aged 30–65 over a six-week period, suggesting a favorable short-term safety profile for this specific formulation.

Why this might work

Small collagen fragments are absorbed through the gut wall into the bloodstream, travel through the body, and do not trigger harmful reactions in healthy women. The body processes these fragments without causing inflammation, organ stress, or cellular damage.
