Somewhere along the way, magnesium got a PR team and a famous Kardashian-Jenner.
Once simply a mineral you might vaguely remember from a science lesson, it’s now in bedtime drinks, powders, mocktails and very aesthetically pleasing cans.
And, for once, the internet’s obsession isn’t entirely misplaced.
Magnesium is an essential mineral involved in hundreds of processes in the body. So the interesting question isn't whether magnesium matters - it does. It's why we've all suddenly started talking about it.
Magnesium does rather a lot
Sleep might be getting all the attention, but magnesium's day job is considerably bigger.
It contributes to normal energy production, muscle and nervous-system function, electrolyte balance and the maintenance of normal bones and teeth.
And we've been getting it from foods like nuts, seeds, wholegrains and leafy greens long before anyone thought to put it in a pastel can.
In other words, magnesium didn't suddenly become useful when wellness discovered it.
We've needed it all along.
So, what about sleep?
A large part of magnesium's recent glow-up has happened after dark.
Magnesium drinks, powders and “sleepy girl mocktails” have become fixtures of elaborate evening routines.
Apparently just going to bed wasn't enough.
But the magnesium-sleep connection isn't purely a social media invention. Researchers have been investigating it for years.
A 2021 systematic review found that magnesium supplementation was associated with falling asleep faster in older adults with insomnia, although the researchers cautioned that the evidence was limited and low quality.
More recently, a 2026 review of 12 randomised controlled trials found some improvements in certain sleep outcomes, but results varied between studies and the overall evidence remained uncertain.
So there is genuine scientific interest here - just not quite enough to declare magnesium a guaranteed ticket to eight uninterrupted hours.
Promising and proven aren't quite the same thing.
Why is everyone drinking it?
Because wellness loves a ritual.
There's something rather nicer about making an evening drink than there is about thinking about your micronutrient intake.
And magnesium isn't alone. Protein had its moment. Fibre followed. Electrolytes escaped the sports-drink aisle. Creatine is suddenly everywhere.
Now magnesium has entered its main-character era.
The difference is that beneath the trend is a nutrient with genuinely important functions in the body.
Do you need a magnesium supplement?
That depends on you.
Many people can get magnesium through their diet, while others may choose to supplement their intake.
The important bit is knowing what you're taking, how much you're getting and why you're taking it - rather than adding something to your routine simply because the algorithm has decided it's this month's must-have nutrient.
And more isn't automatically better. High supplemental intakes can cause digestive side effects, which isn't quite the relaxing evening wellness experience you had in mind.
Our take
We're rather pleased magnesium is finally getting some attention.
Alyve Magnesium+ combines magnesium glycinate with marine magnesium, providing 300mg of elemental magnesium in two capsules.
No mocktail shaker required.
And if you're not sure which nutrients actually make sense for you, that's rather the point of personalisation.

So yes, magnesium is having a moment. But it doesn't need to be a miracle cure to deserve one.
Enjoy the magnesium mocktail. Eat the almonds. Supplement if it's right for you.
We're just pleased magnesium finally hired a decent publicist.
