What you're actually getting
Magnesium glycinate is the form that actually gets absorbed properly, not the cheap magnesium oxide you find stuffed into most budget supps. The "3-in-1" label suggests a blend, likely combining glycinate with one or two other forms for different absorption rates. Whether that layered approach makes a real difference day-to-day is debatable, honestly. But the base ingredient is solid.
At 90 capsules for under a fiver, the price is hard to argue with. My first thought when I see this kind of deal is: what corners are being cut? With supplements, that usually means fillers, low active dose, or a vague proprietary blend with no real transparency. Worth checking the label closely before you commit.
Who this is actually for
If you're someone who wakes up at 3am with calf cramps, or you've noticed your sleep is lighter than it used to be, magnesium glycinate is one of the more sensible things to try. It's also a reasonable shout for anyone who trains regularly and isn't eating a huge variety of whole foods. That's a lot of people, to be fair.
It is not, however, a fix-all. I've seen people chuck magnesium at anxiety, hormones, energy levels, basically the full list. Sometimes it helps at the margins. Sometimes you're just paying for expensive urine.
The honest reservation
No brand name on this one. No listed manufacturer I can immediately verify. Community heat on HotUKDeals is a decent signal that the price is sharp, but it doesn't tell you much about what's inside the capsule. If you're already on a trusted magnesium and it's working, probably not worth switching for the saving.
