How to Take It

Take it anytime

Studied as a twice-daily dose — its effect on bacterial adhesion is short-lived, so one big dose isn't equivalent.

With or without food

On the label

As a dietary supplement, take one serving, 1-2 times daily, mixed with a beverage or into food.

General guidance based on the ingredients, not a substitute for the label or your doctor.

Sources & Scoring

Nutrient data (RDA, UL, and safety thresholds) sourced from the NIH Office of Dietary Supplements and the National Academies Dietary Reference Intakes (DRI).

This is not medical advice. Consult a healthcare provider before making changes to your supplement routine.

The score analyzes what's on the label: ingredient doses vs. studied ranges, chemical forms, evidence levels, and known interactions. It does not verify label accuracy or test for contaminants — for that, look for third-party certifications like USP or NSF.
