What a complete label should establish

  • Serving size and servings per container
  • Every dietary ingredient and its amount per serving
  • Percent Daily Value when applicable
  • Other ingredients, including capsule shell and possible allergens
  • Directions, warnings, distributor and lot details

Why we are withholding a dose table

Public promotional pages and third-party descriptions do not consistently match on ingredient count. Copying a third-party table without confirming that it belongs to the supplied product bottle would be misleading. The uploaded image shows only the front of the bottle.

NIH and FDA considerations

FDA requires a Supplement Facts label for most dietary supplements and does not preapprove their efficacy. If a label lists supplemental niacin, the NIH Office of Dietary Supplements advises that the usual adult tolerable upper intake level is 35 mg per day from supplements unless medically supervised; this is a general benchmark, not a verified statement of the amount in the uploaded bottle.

What to do next

Compare any seller label with the physical product and speak with a clinician before using multi-ingredient supplements, especially alongside medicines. See the ingredient overview.

Medical information: Dietary supplements are not substitutes for diagnosis or treatment. Discuss urinary symptoms or medication interactions with a qualified healthcare professional.
