Garlic powder is usually given 4 to 8 weeks before you decide whether it's worth keeping, taken once a day with food at the dose printed on the label. Anything shorter than a month and you're mostly watching your own expectations. Anything longer than two months without a fixed reference point and you'll never be able to tell. The window matters more than the dose for a routine like this one.
How long does garlic powder take to work on a daily routine
Set the start date in a notebook, because memory is a poor instrument here. Take it at the same meal each day, since a 500 mg capsule on an empty stomach and the same capsule after dinner aren't really the same experiment. Most people running a 90 day supply will know by week 6 whether they want to reorder, which leaves you a month of slack before the bottle runs out.
Nothing about a dried allium powder happens quickly. It isn't a painkiller and it isn't a sedative, so there's no onset you can feel in an hour.
Pick one thing to track and write it down
General wellbeing is too slippery to judge. Choose one measure you care about, note it on day one at a fixed time of day, and check it again at week 4 and week 8. A single number recorded the same way each time beats a vague impression of feeling better, because impressions bend toward whatever you already hope is true.

Write the 8 week mark on the bottle with a marker. When you reach it you'll have several weeks of notes and a clear decision to make, rather than a half empty container and no idea whether it helped.
What to do if you notice nothing at all
Don't double the dose. Scale only within the range the label allows, and if you're already at the top of that range, the honest answer is that this product may not be the one for you. Some people respond to a standardised 1000 mg concentrate and get nothing from a plain 500 mg powder, and that's a formulation difference rather than a dosing failure.
Taking more than the label suggests doesn't buy you a faster result, and it doesn't shorten the 4 to 8 week window either. The trial length is set by what you can reasonably observe, not by how much you swallow. Keep the 500 mg capsule at 500 mg and let the calendar do its work.
The limits of a self run trial
One person, one bottle and one month is a weak study, and no amount of careful note taking fixes that. Your sleep, your meals and the season all move at the same time, so a good week in March might have nothing to do with the capsule. Treat the 8 week window as a way to decide whether a daily habit is worth its $0.14 a day, not as proof that the product changed anything. If you take prescription medication, or you're pregnant, talk to a clinician before you start rather than after.

Buy the 90 count only if you're genuinely ready to run the full window. A 30 count trial is cheaper to abandon, and abandoning a two week test tells you almost nothing. You can always reorder at week 6 once you've seen your own notes. The 90 count usually works out near $0.11 a day against $0.16 for the small bottle, which is worth having only if you'll actually finish it.
