What it is

Polyphenols are a broad class of plant compounds, not a single standardized supplement ingredient or guaranteed digestive outcome.

How to read the research

Look for human studies that match the actual preparation, amount, duration and outcome you care about. Mechanistic or animal research can generate hypotheses but should not be presented as proof of a consumer benefit.

Safety questions

Natural origin does not guarantee safety. Consider dose, duration, allergies, health conditions and medicine interactions.
