In plain English

Taking 10 grams of hydrolyzed collagen peptides daily for 8 weeks in healthy women aged 35 to 60 resulted in mostly mild side effects like nausea or constipation, with no serious side effects reported.

See the scientific wording

Hydrolyzed collagen peptide supplementation at 10g/day for 8 weeks is well tolerated in healthy adult females aged 35–60, with 74.4% of reported adverse events being mild (e.g., nausea, constipation) and no serious adverse events observed, supporting its safety profile for short-term use.

Why this might work

When hydrolyzed collagen peptides are swallowed, they pass through the gut into the blood, travel through the body, and are broken down by the liver and kidneys. The body processes these peptides without triggering harmful reactions, and any minor digestive discomfort comes from temporary changes in gut movement or fluid balance.
