Taking breaks from magnesium glycinate
You can take magnesium glycinate for months at the dose on the label without cycling off, and most everyday nutrients work the same way. Cycling is a real practice for a short list of compounds, and a mineral your body holds in bone and tissue is not on that list.
What magnesium cycling is actually for
Cycling makes sense when a compound builds up in a way that needs managing, or when tolerance to an effect develops and a break restores it. Those are specific situations, and they get applied far too broadly.
Magnesium is not one of them. Your body regulates how much it keeps, and what it does not need leaves. Stopping for 2 weeks to reset something that does not accumulate is a pause with no mechanism behind it.
What a real review looks like
Every 3 months, sit down for 5 minutes with the bottles on the counter. For each one, ask whether it still earns its place. That is the whole review, and it is worth more than any cycling protocol.
I do mine on the first Sunday of the quarter. Three bottles in front of me, one note on my phone, and a decision per bottle. It has removed 2 things over the past year, both of which I had been taking out of habit rather than intent.
Dose, serving, and running cost
Magnesium glycinate is bound to the amino acid glycine, which is why it is usually described as gentle. Two capsules per serving is common, and 120 capsules gives 60 days. At $22 a bottle that is about $0.37 a day, which is the number I compare whenever I think about switching forms.
The panel figure is elemental magnesium. Two grams of a magnesium compound delivers considerably less than 2 grams of the mineral itself, and shoppers who compare the big front-of-bottle number across two different forms are comparing two different things without knowing it.

What happens if you stop
Usually nothing dramatic. Levels drift back toward wherever your food puts them, which for most people is somewhere in the middle. That is a useful thing to know, because it means the decision to stop is low stakes and you can make it on whether the product is doing its job.
What I would not do is stop and start on a whim every 3 weeks. A pause that short tells you nothing, and it turns a simple routine into a series of experiments with no record of any of them.
Take it for months, run a 5 minute review each quarter, and keep the note. That's the whole protocol, and it beats a cycle you invented because a forum said so.
How long I've been on it
Twenty-two months, one bottle at a time, no break longer than a forgotten weekend.
The only thing that ever changed was the form, twice, and both times I noted it in the same place with the same 4 fields. Nothing about that requires a cycling calendar, and a cycling calendar wouldn't have told me anything the note didn't.

If you're looking for a reason to stop, use the quarterly review instead of a rule you read somewhere. It's 5 minutes and it gives you an actual answer.
One thing I check at the review is whether the bottle is being finished on schedule. A 120 capsule bottle at 2 capsules a day should last 60 days. If it's lasting 90, I'm skipping it, and a product I skip half the time isn't doing much of anything regardless of the dose on the panel.
That single check has been more useful to me than any protocol about cycling on and off.
