Our sleep and calm supplements are for UK adults who lie awake at 2am, wake up wired, or just can't switch off after a long day. This is the range we point people to when broken sleep, racing thoughts, or low-grade stress are getting in the way of how they want to feel. Magnesium, ashwagandha, L-theanine, and our own LSC Sleep Complex. Nothing flashy, nothing trendy. Just the formulas our customers actually come back for.
What's different here is what we've left out. No melatonin-style marketing theatre, no fairy-dust doses, no cheap magnesium oxide hiding in a fancy label. Mark hand-picks every brand and our in-house range uses functional doses in forms your body actually absorbs. Free UK shipping over £75. Have a browse and pick the one closest to your situation.

Why most sleep supplements don't work
Most sleep products on the high street fail for one of three reasons. The dose is too low to do anything, the form is the cheapest the manufacturer could get away with (magnesium oxide is the classic offender, poorly absorbed and rough on the gut), or the bottle is padded out with fillers around a tiny sprinkle of the active ingredient. After 30+ years on the shop floor we've seen them all.
The formulas in this range are picked the other way round. We start with what actually helps people sleep better and reduces day-to-day tension, then look for clean-label products at functional doses. Magnesium contributes to normal muscle function and the reduction of tiredness and fatigue. That's the standard we hold the range to.
Who this range is for
Shift workers, light sleepers, and anyone whose brain won't shut up at bedtime. Midlife customers in their 40s, 50s, and 60s noticing that sleep is shallower or shorter than it used to be. Active people training hard during the day who need better recovery overnight. Anyone going through a stretch of higher stress at work or home who wants steady, daily support rather than a knock-out pill.
How to choose
Start with the goal. If muscles feel tight, restless legs are a problem, or you wake up sore, a quality magnesium glycinate is the usual first step. If your head is the issue, racing thoughts at lights-out, ashwagandha and L-theanine sit closer to that lane. If sleep is broken across the night rather than slow to start, our Sleep Complex pairs supportive nutrients in one capsule so you're not juggling four bottles.
Pair it with a sensible routine. Caffeine cut-off by early afternoon, screens down 30 minutes before bed, and a consistent lights-out time will do more for you than any capsule on its own. We won't pretend otherwise.
How to take it
Most products in this range are taken 30 to 60 minutes before bed with a small amount of food or water. Ashwagandha can also be taken in the morning if you're using it more for daytime calm than sleep. Speak to your GP first if you're pregnant, breastfeeding, or on prescription medication. For deeper personalisation our LSC Bloods and Beyond service uses venous blood testing so you're working from real numbers, not guesses.
What's in this range
Magnesium in absorbable forms, our own LSC Sleep Complex, L-theanine for daytime calm without drowsiness, and ashwagandha for stress resilience. Browse the full Sleep category for product-type filtering, or move sideways into the Stress & Mood range if calm during the day is the bigger issue. The whole in-house line lives on the LSC Supplements page.
