The Supplement Facts panel is the single most useful document for judging a supplement, and the page does not show it.
Write briefly: you are considering an order and would like an image of the Supplement Facts panel, the amount of each of the eight ingredients per gummy, the serving size and the number of gummies per bottle. Ask which serving the 60, 90 and 180 day supply periods assume.
Specific questions are harder to answer with a generic reply.
A full answer with numbers gives you something to check against the label and against safe upper limits, such as 40 mg a day of zinc and 4,000 IU of vitamin D for adults. A partial answer tells you what level of transparency to expect. Keep the reply with your order records either way.
