What you're actually getting
Magnesium glycinate is the form that most people in the supplement world will tell you to go for. It absorbs better than the cheap oxide version you find in most supermarket pills, and it's generally kinder on the stomach. The "3-in-1 complex" label suggests there's more than one magnesium compound in here, which can help cover different absorption pathways. Sensible formulation, not a gimmick.
Personally, I started taking magnesium glycinate a couple of years back after a run of genuinely awful sleep, the kind where you wake up at 3am and your brain immediately starts rehearsing every awkward conversation from 2014. Made a noticeable difference. Not dramatic, but real.
Who this is actually for
Look, if you're already sleeping fine, eating well, not particularly stressed, you probably don't need this. But if you're someone who exercises regularly, drinks coffee like it's a food group, or just feels chronically a bit flat, magnesium is one of the few supplements with decent evidence behind it.
At under five quid for 90 capsules, the price is hard to fault. That's a solid three-month supply if you're taking one daily.
Honest reservation: there's no listed brand here, which means quality control is a bit of an unknown. I'd check the label for third-party testing if you can see it before buying. Not a dealbreaker at this price, but worth being aware of.
The bottom line
Not half bad for the money. If you've been meaning to try magnesium and kept putting it off because decent versions are usually pricey, this is a reasonable entry point. Just don't expect miracles overnight.
