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 honest expectations (early wins in days, more stable results by weeks 4–6).

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
"My biggest worry was dependency. I've been down the melatonin road and hated how groggy I felt, and how useless it became after a few weeks. What convinced me to try this was the AM formula — I've never seen a sleep product address the morning side of the problem. Three weeks in and I'm actually tired at the right time at night. That hasn't happened in years."

The afternoon crash disappeared
"I work in healthcare so I'm skeptical of everything. I read the ingredient breakdown, looked up the research behind the DLMO timing approach, and decided it was worth trying. I tracked my sleep with my Oura ring for the full 30 days. My deep sleep percentage went from an average of 11% to 19% over the protocol. That's not placebo."
HOW IT WORKS
Your 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 your morning routine, and the PM formula during your wind-down window. Pair it with the personalised 4-week plan from your 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 your 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 your DLMO window earlier. Most users notice wake-up feels less forced by day 5–7, before the evening changes become noticeable.
Week 2
Reduce the Interference
The focus is on targeting evening cortisol elevation. The primary reason melatonin onset runs late even when you're exhausted. 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 your circadian trough phase is losing stability in the second half of the night. As the AM and PM signals compound across three weeks, sleep cycles begin completing without interruption. This is the week most users notice they're sleeping through to a natural wake time for the first time.
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 forcing it. The clock is no longer drifting.
