How to Take It
Take it anytime
Take it between meals, away from food.
On an empty stomach
On the label
Take 1 tablet 1 or 2 times per day with meals or as directed by your qualified healthcare professional.
Labels usually say “with food” because it's gentler on the stomach, not because it absorbs better. Fasted absorbs more — start there, and switch to a light meal if it bothers you.
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.
