As featured in
- The Independent
Featured in The Independent’s round-up of the best sleep supplements for a full night’s rest.
1. It’s built for both the 3am wake-up, and the bedtime one
Most sleep aids are designed to knock you out at 11pm. That’s rarely the problem. The problem is 3am: wide awake, counting how many hours are left before the alarm.
Sleep is built around affron® saffron, the world’s first patented saffron extract, clinically studied for sleep quality.
The research
24% better sleep quality in a 120-person trial of affron® saffron.
Lopresti AL et al., 2021. Phytotherapy Research. PMID: 34438361.
2. There’s no synthetic melatonin in it
Turn over a melatonin tub and read the back. You’ll find one hormone, plus sweeteners and flavourings. Melatonin helps you drop off. It does nothing for 3am.
Sleep uses Montmorency tart cherry, a natural food source of melatonin, alongside four botanicals.
The research
Tart cherry raised natural melatonin levels by 17% in 7 days.
Howatson G et al., 2012. European Journal of Nutrition. PMID: 22038497.
3. You wake up clear, not groggy
Two capsules an hour before bed. There’s no sedative in it, so there’s nothing to sleep off at 7am.
Customers keep telling us the same thing: they notice the mornings before they notice the nights.
★★★★★

My sleep experiment
What Happened to My Sleep When I Tracked It With WHOOP
7 nights on a WHOOP tracker
This is data from a WHOOP, a biometric sleep tracker. The left shows sleep before taking Earth’s Secret Sleep. The right shows sleep after 7 nights. Same person. Same device. Same routine.
Before Sleep
5 hours 23 minutes of sleep. REM and deep sleep made up just 20% of the night, not enough for the body and brain to properly recover.
After 7 nights
9 hours 26 minutes of sleep. REM and deep sleep rose to 48% of the night, with less time awake and fewer disruptions.
What it means for you
One person, one tracker, not a clinical trial. But deep and REM sleep are the stages where your body and brain actually recover. Without enough of them, you can spend eight hours in bed and still wake up exhausted.
- Longer Total Sleep Time
- More Deep & REM Sleep
- Less Time Awake at Night
- Fewer Sleep Disruptions
★★★★★
“As a sleep expert, I’ve seen countless sleep solutions. Earth’s Secret’s approach with affron® Saffron is backed by real science, and a truly exceptional product. I have been recommending it to my clients.”
Why it costs what it costs
Why most brands avoid saffron
Saffron is one of the most expensive botanical ingredients in the world, and one of the most effective.
That’s why most sleep supplements are built around cheaper ones.
So how is Sleep from £1.27 a night?
- We sell direct, so there’s no retail markup.
- We don’t pay for celebrity endorsements.
- The money goes in the capsule.
