FREE 4-Week Personalised Protocol based on the quiz results
*Measurable reduction in nighttime wakeup frequency detectable in the first 7 days of tracking data on Oura, WHOOP, or Apple Watch. 30 days to verify the shift independently.
Always check with a healthcare professional if pregnant, breastfeeding, managing a condition, or taking medications. Consult a healthcare provider if you have a hormone-sensitive condition, thyroid disorder, or are taking antidepressants or MAO inhibitors. Do not exceed recommended serving size.
Circadian alignment is driven most by signals and consistency (morning light, stable wake time, dim evenings, meal timing). This program is designed to make those signals easier to execute daily, while the AM/PM formulas support the routine with a simple, structured approach.
Results vary, but early improvements often show in 3–7 days, with more noticeable stability by weeks 4–6 when the routine is followed consistently.

A portion of proceeds is reinvested into sleep education resources; free guides, research summaries, and tools that help more people understand circadian alignment. The mission is simple: make sleep timing easier to fix with clear, practical education (not confusion or hype).
Designed for daily use with clear AM + PM timing.
Built to support routine consistency, not dependence.
Full ingredient lists, clear purpose for each SKU, and measurable expectations. WASO events and sleep latency begin shifting in the first 7 days of tracking data. N3 deep sleep architecture stabilises by Day 30.

Sleep timing finally feels predictable
"I'd been taking magnesium for two years and still waking up at 3AM like clockwork. I assumed that was just my body now. By week two of the protocol my wake-ups dropped from five nights a week to maybe one. I didn't expect it to work that fast and I definitely didn't expect to feel the difference in the mornings too."

Tried magnesium, melatonin, everything
"The Oura data told the story. HRV up 22% at day 14. Deep sleep from 9% to 17% over 30 days. Those are not subjective impressions. Those are biomarker measurements. Magnesium and melatonin never produced a number that could be pointed to. This did."

The afternoon crash disappeared
"The standard in any credible health intervention is ingredient source disclosure, and a mechanistic explanation that holds up to scrutiny. Circadia provided all three before purchase. Deep sleep moved from 11% to 19% over 30 days."
HOW IT WORKS
A circadian routine in 2 minutes a day.
Circadia is a simple AM + PM system designed to strengthen the two signals that control sleep timing: a clearer “start of day” and a clearer “night switch.” Take the AM formula with the morning routine, and the PM formula during the wind-down window. Pair it with the personalised 4-week plan from the quiz results for the fastest, most reliable progress without complicated tracking or guesswork.
WHY THIS WORKS
Two signals. One stable rhythm.
Most “sleep fixes” focus only on the night. Circadian alignment is different it’s about strengthening the day signal (so mornings feel switched on) and protecting the night signal (so sleepiness shows up on time). Circadia supports both sides with a simple AM + PM structure that fits real life, so timing becomes more predictable without overthinking every habit.
How the 4-Week Circadian Program
Works
Most sleep protocols track habits. This one tracks the biology.
Week 1
Set the anchors (stability first)
The focus is on establishing a stronger morning cortisol awakening response. The upstream biological event that determines when sleep pressure builds later that night. AM Rise is taken at a consistent time each morning to begin shifting the DLMO window earlier. Most respondents notice waking is less forced by Day 2. The morning signal begins calibrating before the evening changes become measurable in tracking data.
Week 2
Reduce the Interference
The focus is on targeting evening cortisol elevation. The primary reason melatonin onset runs late even when exhaustion is present. PM Drift supports the wind-down phase during the cortisol-melatonin transition window. This is where most users report their first consistently earlier sleep onset, typically between nights 10–14, as the DLMO signal begins shifting into its natural range.
Week 3
Consolidate the Architecture
The focus is on reducing WASO events. The nighttime wake-ups that signal circadian trough instability in the second half of the night begin resolving. As the AM and PM signals compound across three weeks, sleep cycles begin completing without interruption. This is the week the overnight wakeup pattern, which has been the primary disruption, begins clearing consistently.
Week 4
Stabilize the Rhythm
The focus is on locking in a self-sustaining 24-hour feedback loop between the morning cortisol signal and the evening DLMO window. By week 4, the protocol has done its job. Morning energy arrives on cue, evening wind-down begins without effort, and sleep timing holds consistent without requiring management. The protocol is complete. The 30-day entrainment window has closed. What follows is a clock that runs independently.
