Who’s this for?
If you’ve tried every sleep remedy under the sun - from gummies to magnesium, sleep apps to herbal teas... and still wake up tired, this is for you.
It’s for you if:
- You struggle to fall asleep or stay asleep through the night
- You want a natural solution that works with your body, not against it
- You’re tired of feeling groggy, foggy, or wired at 2am
- You’re done with synthetic pills, dependency, or quick fixes that don’t last
- You just want to feel like yourself again - rested, clear, and in control
This isn’t another generic sleep aid.
It’s for people who feel like they’ve tried it all - and are ready for something that actually works.
Ingredients & Science
Earth’s Secret Sleep Complex blends five clinically researched ingredients that work synergistically to promote restful, natural sleep - without next-day grogginess.
Affron® Saffron (28 mg):
Backed by 6+ human clinical trials, Affron® has been shown to improve sleep quality, reduce time to fall asleep, and support mood balance in just 2 weeks.
Passionflower Extract:
Traditionally used for calming the nervous system, modern studies show Passionflower supports GABA activity - promoting deeper sleep and reduced restlessness.
Tart Cherry Extract:
A natural source of melatonin, Tart Cherry helps regulate your body’s sleep-wake cycle and improve sleep efficiency and duration.
Lavender & Chamomile (Apigenin-Rich):
Shown to reduce heart rate and anxiety, helps to support faster relaxation and improved sleep latency (time to fall asleep).
💡 All ingredients are third-party tested, non-GMO, and free from synthetic fillers

Claim My FREE GiftsQuestions? We’ve Got Answers.
When will I notice a difference?
Everyone’s different. Some customers notice a change in their first week; for others it builds over a few weeks.
The studies on affron® saffron ran for 28 days, so we recommend taking Sleep every night for at least a month to give it a fair chance.
Will I feel groggy in the morning?
Sleep contains no synthetic melatonin and no sleeping tablets. It’s made with five plant ingredients, and customers often tell us they wake up feeling clear.
Can I stop taking it whenever I like?
Yes. There’s no synthetic melatonin or sleeping tablets in Sleep, so there’s nothing to wean off. You can stop whenever you like.
What’s in it?
Five plant ingredients: affron® saffron, Montmorency tart cherry, organic passionflower, organic lavender and organic chamomile.
Every capsule is vegan, third-party tested and made in the UK, with no synthetic fillers.
Who can take Sleep?
Sleep is for adults aged 18 and over. It isn’t recommended during pregnancy or breastfeeding.
If you take any medication or have a medical condition, check with your GP or pharmacist before you start.
Can I take it with magnesium or other supplements?
Yes, you can take Sleep alongside magnesium. If you take other supplements or any medication, check with your GP or pharmacist first.
How long does a pouch last?
Each pouch holds 60 vegan capsules. At two capsules an hour before bed, that’s 30 nights.
Why do you recommend a subscription?
Sleep works best taken every single night, and it builds the longer you take it. Running out halfway through the month breaks that rhythm, and a subscription means your next pouch arrives before you need it.
Subscribers also save 25% on every order and get free milestone gifts. You can skip, pause, edit or cancel any time.
Do you offer a guarantee?
Yes. Every order, bundles included, is covered by our 60-night money-back guarantee. Take Sleep for 60 nights, and if you’re not sleeping better, email us at hello@earthsecret.com and we’ll refund you.
Do you ship outside the UK and Ireland?
Yes, we ship worldwide from our Northern Ireland warehouse. UK orders usually arrive within 2 working days of dispatch, Ireland within 2–3 and the EU within 3–5.
Further afield it can take a little longer because of customs, and every order is fully tracked.
