★★★★★Verified review · Mushroom Cacao
“It calms and quiets me so well that I fall asleep within minutes.”
The problem
Eight hours in bed. Still tired?
Time in bed is not sleep. Depending on your tracker, the score drops when you sleep too little, wake in the night, or your body is still stressed while you sleep.
7–9 h
a night is what the National Sleep Foundation’s expert panel recommends for adults aged 18 to 64 (7–8 h from 65). Hours in bed are not hours asleep.
Hirshkowitz et al., 2015 · Sleep HealthMost sleep scores are built from how long you sleep, how often you wake and how settled your body is overnight. The evening moves all three: what you drink, what you look at, and how fast you wind down.

The Deep Sleep System
The last hours of the evening shape the night.
Three moments, three jobs. Reishi is the base, every evening. The cacao replaces the last tea or glass of wine. The gummies are for lights down.
02 · The last cup
Mushroom Cacao
Peruvian cacao with 500 mg Reishi, 250 mg valerian and 100 mg magnesium a scoop. Magnesium contributes to normal psychological function.
1 scoop in hot milk, about two hours before bed
03 · Lights down
Calm Reishi Gummies
500 mg Reishi, 100 mg GABA and 60 mg saffron in two lemon-lime gummies. No sugar, no melatonin.
2 gummies, phone out of the room
Food supplements, not medicines. The Mushroom Cacao contains valerian: not during pregnancy or breastfeeding, not under 18, and not with sedative medication.
The research
Saffron · in the Calm Reishi Gummies
GABA · in the Calm Reishi Gummies
Reishi · the core of the routine
Why these three. The human trials.
Studies in people, against a placebo. None of them tested our exact products or doses, so each one says what the trial used, and what ours contains.
Poor-sleep scores fell by a quarter.
Saffron
Before15.75
After11.74 (−25%)
Placebo
Before14.74
After13.46 (−9%)
Insomnia Severity Index, lower is better. Lopresti et al. 2020, Journal of Clinical Sleep Medicine: 55 adults with self-reported poor sleep, 28 mg a day of a saffron extract (affron) for 28 days, double-blind, against placebo. Funded by the extract’s maker. Read the paper
Across the placebo-controlled trials, sleep-quality scores were about 2 points better with saffron (Lian et al. 2022, Sleep Medicine, a meta-analysis). Read it
Ours: 60 mg of saffron extract in two gummies.
Asleep sooner, measured in a sleep lab.
GABA
Before13.4 min
After5.7 min
Placebo

After15.2 min
Minutes to fall asleep, measured overnight. Byun et al. 2018, Journal of Clinical Neurology: 40 adults with insomnia symptoms, 300 mg a day of GABA from fermented rice germ for 4 weeks, double-blind, against placebo. Questionnaire scores did not differ from placebo. Funded by the GABA supplier. Read the paper
Ours: 100 mg of GABA in two gummies.
Sleep disturbance fell 25%.
Reishi

Sleep-disturbance score (0–100), lower is better. Zhao et al. 2012, Evidence-Based Complementary and Alternative Medicine: 48 women with fatigue during breast-cancer treatment, 3 g a day of Reishi spore powder for 4 weeks, against placebo. Sleep was a secondary measure; blinding was not reported. Read the paper
Ours: 1 g a day of a 10:1 fruiting-body extract, a different form.
In the lab. In rats given Reishi extract, total sleep and non-REM sleep got longer, while deep (slow-wave) sleep and REM did not change. The effect came with a rise in TNF-α, a signal the body uses to regulate sleep, and blocking TNF-α in the brain weakened it (Cui et al. 2012).
No study has tested this exact routine. So we put it to a simpler test: your own sleep score, five nights, or your money back.

Questions
Before you start
How does the money-back promise work?
Save your sleep score the morning after a normal night, before your first dose (night 0), and again after the fifth night. If it has not risen by at least 15%, reply to your order email with both screenshots within 14 days of delivery and we refund everything you paid, delivery included. You keep the product. It covers the £10 start and the Deep Sleep System.
What do I get for £10?
A month of Reishi: 60 capsules (two after dinner), or a 30 g pouch of powder (two scoops in a warm drink). Plus the Deep Sleep Guide and the 5-night log, which you can download now. UK delivery is £4.95.
I don’t have a tracker. Can I still try it?
Yes. The 5-night log has a simple 1–10 morning rating for how rested you feel. The money-back promise is measured on a tracker’s sleep score, so without one the 60-day returns policy applies instead.
Which trackers count?
Any that gives a nightly sleep score: Garmin, Apple Watch (through the Health app or a sleep app), Oura, WHOOP, Fitbit, Samsung, Withings, Polar and others. Compare the same tracker with itself.
Is there melatonin in it?
No. None of the three contains melatonin, and none has added caffeine (the cacao carries only the trace cocoa naturally has, about 3–4 mg a cup; a mug of coffee has about 100 mg). Reishi is a mushroom extract; the gummies add GABA and saffron, the cacao adds valerian and magnesium.
Will it make me drowsy?
Reishi and the gummies are not sedatives. The Mushroom Cacao contains valerian, which can make some people drowsy: drink it about two hours before bed, and do not drive afterwards. See how you feel on night one.
When will it arrive?
UK orders are packed within one to two working days and usually arrive three to five working days after you order, with a tracking link by email. Start the 5 nights whenever suits you within 14 days of delivery.
What happens after the first month?
Nothing, unless you choose. Reishi capsules are £30 a month (powder £20), or 20% less on Subscribe & Save, which you can pause or cancel any time.
Why is it only £10?
It is a first order for new customers, one per customer. Reishi capsules are normally £30. We would rather you test it on your own tracker than read about it.
Can I take all three together?
Yes, that is the system: two Reishi capsules (1,000 mg) after dinner, one scoop of cacao (500 mg Reishi) and two gummies (500 mg Reishi). Each stays within its own label’s daily serving. The gummies contain polyols, which in large amounts can have a laxative effect.
Is this a subscription?
No. It is one order. Nothing renews and there is nothing to cancel.
What is in the Deep Sleep System?
A month of Reishi (60 capsules or 30 g powder), a 180 g pouch of Mushroom Cacao (30 cups) and a jar of Calm Reishi Gummies. Today £49.50 with capsules or £44.50 with powder, half the usual price.
Who should not take it?
Not for under-18s, or during pregnancy or breastfeeding. If you take medication, ask your doctor first. The cacao contains valerian, so not with sedative medication.
Five nights. £10.
A month of Reishi, the guide and the log. +15% on your sleep score in five nights, or your money back, delivery included.
