Nowhere on the page are the milligram amounts for the eight ingredients. There are still ways to ask.
Start with the product page and the Ingredients page for a label image. If none is shown, use the contact page to email the seller. The refund and order pages are unlikely to have amounts, but they carry terms worth reading.
Be wary of third-party sites that quote numbers without a source, since they may be wrong or outdated.
Request the Supplement Facts panel, the per-gummy amounts, the serving size, the gummies per bottle and the extract ratios for the botanicals. State that you want them before you order. Keep the message and any reply, and weigh the answer, or the lack of one, in your decision.
