Here's something most people don't know about magnesium: taking it isn't enough. The form matters – and most supplements don't tell you that.
Magnesium is involved in over 300 biochemical processes in the body. Sleep regulation, stress response, cognitive function, muscle recovery – it has a hand in all of them. But different forms of magnesium behave differently in the body. Some calm the nervous system. Some cross the blood-brain barrier. Some fuel the cellular machinery behind physical performance. Use the wrong one for what you're trying to fix, and you're leaving most of the benefit on the table.
Most supplements give you one form – usually magnesium citrate or oxide, chosen because it's cheap – and call it done. But that's not a solution... that's just a shortcut.
Magnesium for Sleep: Tired Shouldn't Mean Wired
We’ve all been there: you're exhausted before you even get into bed, but the moment your head hits the pillow, your brain runs a full audit of everything that happened this week. An hour later? Still awake, still tired, still wired.
That gap between exhaustion and actual sleep is a nervous system problem. And magnesium is one of the most powerful tools for closing it.
Magnesium bisglycinate – one of the most bioavailable forms – has been found to significantly reduce insomnia severity scores compared to placebo over four weeks [REF] A wider systematic review found that magnesium supplementation increased melatonin production, reduced cortisol levels at night, and meaningfully improved sleep onset [REF]
The mechanism is straightforward: magnesium bisglycinate activates GABA receptors – the brain's natural off-switch – while magnesium taurate calms the specific kind of mental noise that keeps you alert when you're supposed to be winding down. They're not sedatives – they restore the physiological conditions your body needs to sleep the way it's designed to.
SLEEP combines both forms with valerian root, glycine, apigenin, and Montmorency cherry – a blend built around one outcome: getting you to sleep, keeping you there, and making sure you wake up restored.

Magnesium for Stress: Less Cortisol, More Control
Stress isn't just a feeling.
It has a measurable biological signature – tight muscles, elevated heart rate, a jaw you didn't realise you were clenching. And at the centre of it is cortisol: the hormone your body floods your system with under pressure.
What most people don't know is that magnesium and cortisol are directly linked. Stress depletes magnesium. And low magnesium makes stress worse. Magnesium supplementation has been shown to measurably reduce cortisol excretion [REF] – and the relationship runs both ways: magnesium deficiency amplifies susceptibility to stress, while chronic stress accelerates magnesium loss. You can't resolve one without addressing the other.
Magnesium taurate is well-suited here. Taurine acts as a natural brake on the nervous system – working alongside magnesium to interrupt the stress cycle at the source, not mask the feeling of it. The result? A calmer baseline.
CHILL pairs this with L-theanine, lemon balm, rhodiola, and phosphatidylserine – compounds with well-documented effects on stress resilience, working through the same system from multiple directions.
