Circadian Protocol · 24-hour ritual

A steadier day,
timed to your biology.

Three protocols — morning, midday, evening — timed to the cortisol, adenosine, and melatonin curves your body already keeps.

The 24-hour ritual

One day. Three signals.Stacked the way your body keeps time.

Scroll. The day arrives in three tilted cards — morning, midday, evening — each timed against a real biological window. Skip a phase and the others quiet down. Skip none and the rhythm holds.

Activate

Wake the system, gently.

Light first. Liquid second. Cortisol allowed to peak — not spiked. The day starts before the screen does.

The 14:00 trough is adenosine, not coffee. Stacking caffeine fights chemistry. We support the trough and let it pass.

Why most stacks plateau

Ingredients are easy.
Timing is the protocol.

Most stacks treat the day as one unit. We dose each phase on its own clock — different stack, different hour, different goal.

412 participants · 11-week pilot · 2024
01 · 06:30

The 24-hour curve isn't a metaphor.

Cortisol peaks 30 min after waking. Adenosine builds across the day. Melatonin should rise from 21:00.

02 · 400 mg

Mega-doses miss the timing.

You don't need 600 mg of magnesium at noon. You need 400 mg at the right hour.

03 · 14:00

The afternoon dip is adenosine.

That 14:00 wall is your A1 receptor saturation, on schedule. We support the trough — we don't fight it.

04 · 21:00

Sleep is downstream of evening.

Nine ingredients can't override a 22:00 espresso, a phone in bed, or a midnight snack.

Midday science

The 14:00 dip
isn't willpower.

Adenosine accumulates from the moment you wake. By early afternoon, it saturates the A1 receptors that govern alertness. Caffeine occupies the same receptors temporarily — stacking more compounds the cortisol cost.

The Midday capsule is adaptogenic, not stimulant. The trough still happens — it just stops bottoming out.

How it works

From doorstep
to ritual in a week.

We don't ship until your protocol is calibrated against your actual day. Less waste, less guessing, faster signal.

  1. 01Onboarding · 90 seconds

    Schedule against your day.

    We ask three questions — typical wake time, lunch hour, intended bed time. The protocol windows snap to your actual schedule, not a generic one.

  2. 02Optional · zero-required

    Pair with a wearable (optional).

    Connect Oura, Whoop, Apple Health, or skip. Wearable data refines the recommendation each week — earlier wind-down if HRV stays low, lighter AM stack if cortisol spikes.

  3. 03Cohort cycle · monthly

    Receive the 28-day cohort.

    AM sachets · Midday capsules · PM tincture, dosed per phase. Restocks ship 4 days before you run out. Pause, skip, or step down anytime.

From the pilot review

What stood out wasn't dose strength — it was timing discipline. Halo Daily anchors every active to the right window. That's what the literature has been asking for.

Common questions

What people
actually ask.

We answer the same nine questions in nearly every onboarding call. Here they are, in writing, so you don't have to schedule one.

  • No. The Midday capsule contains no caffeine, no synephrine, no yohimbe. The adaptogenic blend (rhodiola + lion's mane + alpha-GPC) supports adenosine balance instead of overriding it. If you drink coffee, this replaces — not stacks with — a second cup.
