    Published: Mon, Apr 27

I’d lie in bed for hours, completely exhausted but unable to fall asleep. I was restless, my mind wouldn't stop, and honestly I'd start to dread the evening because I knew this cycle would repeat itself. 

 

The next day, I’d wake up feeling drained, running on empty, trying to keep it together, just a person trying to get through.

 

That’s when I came across this special, patented saffron called Affron® Saffron. It’s been tested and backed by 21 different human studies. Within the first night, I slept 9 hours & and sleep was something that just came naturally, I didn't dread going to bed every again. 

 

So, like any supplement founder would, I used my own experience and created the worlds first saffron formula with other sleep-inducing ingredients to create the Sleep Complex. 

 

Here's what the science says - and why it works.

5 REASONS YOU CAN'T SLEEP - AND WHAT AFFRON® SAFFRON DOES ABOUT IT:

1. Your brain can't switch off at bedtime. Affron® Saffron is the only natural ingredient with 21 clinical trials proving it can fix this.

If your mind never stops at night, this could be a serotonin imbalance. Your brain converts serotonin into melatonin as darkness falls. When your stress response stays activated - which happens more and more after 45 - serotonin production drops. Your brain stays in alert mode. The thoughts keep coming because chemically, it thinks it needs to. Affron® saffron works directly on the serotonin pathway, and has been shown to improve slepe quality by 24%, 

More info on the study:

  • In 120 adults with poor sleep, 28mg of Affron® daily improved sleep quality by 24% in just 28 days while increasing natural melatonin levels without taking a single melatonin pill. (Lopresti et al. 2021, Phytotherapy Research)

2. Your cortisol spikes at night which keeps you awake - Affron® Saffron lowers the internal stress response.

Cortisol is your alertness hormone. It should peak in the morning and fall through the day. After 45, that curve often flattens. Cortisol stays elevated into the evening - keeping your nervous system in low-level alert when it should be in deep recovery. Saffron addresses cortisol from the inside by lowering the internal stress response.

More info on the study:

  • In a 2025 trial of 165 adults with moderate insomnia, Affron® reduced perceived stress while improving sleep quality at the same time. In a separate 2018 study, 30mg of saffron daily for 8 weeks significantly improved sleep scores in adults with high stress. Better sleep and lower stress improved together. (Jackson et al. 2025 / Eating and Weight Disorders 2018)

3. You're not getting enough deep sleep - Affron® Saffron improves objective sleep efficiency.

Deep sleep, slow-wave sleep - is where your body repairs itself - where memories consolidate & where your immune system recovers. You can spend 8 hours in bed and still wake exhausted if your deep sleep is fragmented or shallow. Affron® Saffron - the only natural sleep ingredient with objective sleep tracker data in adults aged 55 shown to help you sleep 7 hours and wake feeling like you actually slept.

More info on the study:

  • In a 2025 double-blind study of 52 adults aged 55–85, 30mg of saffron daily for 4 weeks improved sleep efficiency measured by sleep trackers. Participants fell asleep faster, stayed asleep longer, and results were confirmed by devices, not just self-report. (Food & Function 2025, n=52)

4. Your body isn't making enough melatonin - Affron® saffron helps naturally produce it.

Natural melatonin production declines with age. Most people take synthetic melatonin tablets. The problem is that synthetic melatonin replaces your body's own production - over time your brain makes even less of its own & you build dependency. Affron® Saffron helps raise your body’s own evening melatonin levels through the serotonin pathway.

More info on the study:

  • Affron® helps raise your body’s own evening melatonin levels through the serotonin pathway, confirmed in the Lopresti 2021 trial of 120 adults. Not by adding synthetic melatonin, but by supporting the system your brain uses to produce it naturally. No dependency. No diminishing returns.

5. Most Sleep Problems Have More Than One Cause. Earth's Secret's Sleep Complex Helps Fix The Causes.

This is why nothing has worked.

 

A melatonin tablet only addresses hormone levels. Some only relaxes muscles. CBD only addresses anxiety. None of them cover all five root causes of insomnia simultaneously.

 

This is why we created Earth's Secret Sleep Complex.

A multi-action formula built to target the real causes of poor sleep using clinically studied ingredients that work together, not against each other.

 

At the centre is Affron® saffron at the exact researched dose - helping support stress, mood, and healthy sleep rhythm in one ingredient.

 

Then we strengthened it with proven sleep allies:

Montmorency Tart Cherry - supports natural melatonin and longer deeper sleep.

Lavender - helps calm the mind and reduce restlessness before bed.

Passionflower - supports GABA activity to help switch off racing thoughts.

Chamomile - helps relax the nervous system and reduce night waking.

 

One formula. Multiple sleep pathways. Designed for people who need more than a quick fix.

More info on the study:

  • Affron® Saffron Extract (28mg)
    In a 2021 randomised, double-blind, placebo-controlled trial of 120 adults with poor sleep, 28mg of Affron® daily for 28 days improved sleep quality by 24% and supported natural evening melatonin levels. (Lopresti et al. 2021, Phytotherapy Research)
  • Montmorency Tart Cherry
    In a randomised controlled trial, adults with insomnia who consumed Montmorency tart  juice twice daily for 2 weeks increased total sleep time and time in bed asleep compared with placebo. (Pigeon et al. 2010, Journal of Medicinal Food)
  • Lavender
    A placebo-controlled clinical trial found lavender supplementation improved sleep quality and reduced symptoms of restlessness in adults with sleep complaints. (Kasper et al., Phytomedicine)
  • Passionflower
    In a double-blind study, participants using passionflower showed improvements in sleep quality compared with placebo, with benefits linked to calming GABA-related activity. (Ngan & Conduit 2011, Phytotherapy Research)
  • Chamomile
    A clinical trial in adults with disturbed sleep found chamomile extract helped improve sleep quality and daytime functioning versus placebo. (Zick et al., BMC Complementary Medicine and Therapies)

The Results You Can Expect 
With Sleep Complex

I wore a Whoop sleep tracker to show exactly what happens to sleep quality with and without Earth's Secret's Sleep Complex.

 

Before - multiple awakenings through the night. Low REM. Broken sleep cycles. Total sleep time cut short by waking and lying there.

 

After 7 nights on Sleep Complex - fewer awakenings. Longer REM cycles. Full 90-minute sleep cycles completing. Total sleep time significantly increased.

 

Key improvements:

  • Total sleep: 5h 23m → 9h 26m
  • REM sleep: 0h 58m → 2h 26m
  • Awakenings: reduced significantly
  • Sleep cycles: completing fully instead of surfacing

"If you’re exhausted, sceptical, and tired of sleep aids that never seem to work - I made the Sleep Complex to finally put an end to your search to sleep"
