The directions
One gummy, one glass, one window before a meal
The whole routine fits in a sentence. This page prints that sentence, takes it apart, and says which parts are fixed and which are left to you.
A drawing, marking the 8 oz glass named inside the serving.
One gummy, once
The instruction is a single gummy a day. Not two, and nothing larger to begin with.
An 8 oz glass of water
The glass is named inside the instruction rather than added after it, which puts it in the serving.
Twenty to thirty minutes before a meal
For best results the product asks for that window ahead of eating. It is a band of ten minutes, not a single instant.
The same hour each day
A once-daily format asks for regular spacing and nothing else, so the practical move is to hang it on a meal that does not move.
Reading the instruction closely
The wording is short enough to quote whole: take one (1) gummy daily with an 8 oz. glass of water, and for best results take 20-30 minutes before a meal. Three things are fixed in that sentence and one is not.
Fixed: the amount is one gummy, the liquid is 8 oz of water, and the frequency is daily. Not fixed: which meal. The product asks for a window ahead of a meal without naming one, so the meal is yours to pick.
Picking the meal
The practical test is which meal happens at roughly the same time every day. For most people that is dinner rather than lunch, because lunch moves around. Once the meal is chosen, the half hour before it becomes the slot, and the habit sits on something that already happens.
If a day gets missed
Take the next one at the usual time. The instruction is one gummy daily, and nothing in it invites doubling up to make a missed day good.
How long to give it
The seller's own answer sits in the guarantee: it asks for at least 30 days of use before a refund is requested, which is the clearest signal available about the span the product is judged over.
Questions
About taking it
Can I take two in a day?
The instruction is one gummy daily. It does not describe a larger amount, so there is no published basis for taking two.
Does it have to be water?
Water at 8 oz is what the instruction names. It does not mention any alternative, so nothing else is suggested here.
What if I forget until after I have eaten?
The 20 to 30 minute window is described as the way to get the best results, not as a requirement. The instruction publishes no advice about taking it late, so none is invented.
Morning or evening?
Neither is specified. What is specified is the window before a meal, so the choice follows whichever meal in your day is the most regular.
How long before I should expect anything?
No timeframe is published. The nearest published figure is the 30 days of use the seller asks for before a refund request.
