Switching from garlic oil macerate to garlic powder takes about 1 day, not a taper, but the dose almost never carries across. A macerate is measured by the oil weight it was steeped in, while a dried powder is measured by allicin potential in micrograms, and those 2 numbers live on different scales entirely.
Why the two garlic labels cannot be read the same way
Garlic oil macerate is made by soaking sliced garlic in a fixed vegetable oil and then standardising the finished oil, so the label figure, often 1000 mg or 5000 mg, describes the oil matrix around the garlic rather than the garlic itself. Dried garlic powder is standardised differently. A typical 1000 mg tablet is described by its allicin potential, commonly 5000 mcg to 10000 mcg, and that number reflects how much allicin the powder can generate when it contacts moisture in the gut.
You have 2 different units describing 2 different things. One is a delivery vehicle, the other is a chemical yield.
Macerates also carry the oil into the stomach, which slows emptying and often makes them the gentler of the two on the lower oesophagus, a point that matters once you've been taking it for years and notice the difference on a switch. Dried powder tablets are usually enteric coated for exactly that reason, which changes where in the tract they dissolve.
What to check before you swap
Look at the allicin potential line on the new product, not the milligram weight. If your old macerate was described as 1000 mg and the new powder as 1000 mg, you've compared nothing. Find the allicin figure, keep it between 5000 mcg and 10000 mcg per tablet, and you're in the range most dried garlic products are designed around.

Start with 1 tablet with your largest meal for 7 days, then move to 2 if you want the higher end. Food does real work here, and it's not a suggestion. A 500 mg powder tablet taken with 10 g of dietary fat from a meal behaves very differently from the same tablet swallowed on an empty stomach at 7 am.
There's a constraint worth naming. If you're on blood thinning medication, or have surgery scheduled within 2 weeks, garlic is one of the supplements you should clear with a clinician before starting or switching rather than after. That's true of both forms, and the switch does not change it.
What the first month of switching should look like
Week 1 is 1 tablet daily with food. Week 2 is the same, held steady. From week 3 you can step to 2 tablets if you're going to, and week 4 is the earliest point at which comparing one form against the other tells you anything at all. Judging a switch at day 3 is the most common mistake, and it usually produces a conclusion that has nothing to do with the product.
The oil carries roughly 2.5 times the fat per serving of a comparable powder tablet, which is why some people find the macerate easier on an empty stomach and the powder easier to schedule. Neither is better. They suit different routines.

Track 2 things during that month: whether you get the repeating taste or reflux you had with the oil, and whether the tablet schedule is one you keep without thinking about it. Those 2 answers decide the switch, not any dramatic change you were hoping for in 5 days.
No taper is needed. Finish the macerate one day, start the powder the next, and let the month do the work.
Frequently asked questions
Do I need to taper?Show answerHide answer
No taper is needed. Finish one and start the other the following day.
Will the dose match?Show answerHide answer
Check the nutrient line, since a different form usually changes the serving count.
How long before I can judge the change?Show answerHide answer
Give it a month of steady use before comparing anything.
