You lie down. Your body is tired. But your brain won’t switch off. Or you fall asleep easily enough — and then find yourself wide awake at 3am for no obvious reason. Or you sleep a full eight hours and still wake up exhausted.
If any of that sounds familiar, you’re not alone. Sleep problems affect around a third of UK adults. And while most people blame stress, screens, or a busy mind — the underlying cause is often something far more fixable.
Why Most Sleep Advice Misses the Point
The standard advice — no screens before bed, keep your room cool, stick to a routine — is all reasonable. But it treats sleep as a behavioural problem when, for many people, it’s actually a nutritional one.
Your body needs specific nutrients to produce the hormones and neurotransmitters that govern sleep. When those nutrients are missing — which they often are in UK adults — the sleep process breaks down, no matter how good your bedtime routine is.
Here are the three most commonly deficient.
1. Magnesium Glycinate
Magnesium activates the parasympathetic nervous system — the part responsible for rest and recovery. Without enough of it, your nervous system struggles to downregulate in the evening, leaving you wired even when you’re tired.
It also plays a direct role in regulating melatonin (your sleep hormone) and GABA (the neurotransmitter responsible for calming neural activity). Magnesium Glycinate is the most bioavailable form — absorbed well, gentle on the stomach, and notably more effective for sleep than cheaper forms like magnesium oxide.
Most people notice a difference within 7–10 days.
2. Ashwagandha KSM-66
High cortisol in the evening is one of the most common — and most overlooked — reasons for poor sleep. Cortisol is your alertness hormone. When it stays elevated into the evening, your body simply can’t wind down properly.
Ashwagandha — particularly the KSM-66 extract, which is the most clinically studied form — directly lowers cortisol levels. Multiple clinical trials have shown it reduces both the time it takes to fall asleep and the number of night wakings, while improving subjective sleep quality and morning alertness.
It’s particularly effective for people whose poor sleep is driven by stress, anxiety, or an overactive mind.
3. Zinc
Zinc is less talked about in the context of sleep, but the research is clear: it plays a key role in melatonin synthesis and the regulation of NREM sleep (the deep, physically restorative phase). Deficiency is common, especially in people who sweat regularly through exercise — zinc is lost through sweat and not always adequately replaced through diet.
Low zinc is also linked to more frequent night wakings and reduced overall sleep duration.
The Evening Routine That Actually Works
These three nutrients work best taken together in the evening, around an hour before bed. Magnesium Glycinate relaxes the muscles and nervous system. Ashwagandha brings cortisol down. Zinc supports melatonin production. Together, they address the three most common nutritional causes of poor sleep.
No prescriptions. No dependency. Just the foundation your body needs to do what it was designed to do.
