Inside every dose

Full label, full doses.

No proprietary blends — every dose printed here is printed on the box.

Paraxanthine (enfinity®)

150 mg

Caffeine's primary active metabolite, delivered directly for calm alertness via adenosine receptor antagonism — without the jitter-crash cycle or the metabolic variability of caffeine itself*

Citicoline (Cognizin®)

250 mg

Supplies choline for acetylcholine production and cytidine for cell-membrane repair, supporting frontal-lobe cellular energy*

L-Theanine (Suntheanine®)

200 mg

Promotes alpha-wave activity; smooths alertness without sedation*

L-Tyrosine

750 mg

A precursor your body uses to build dopamine, norepinephrine, and epinephrine — supports cognitive performance under stress*

Vitamin B12 (Methylcobalamin)

250 mcg

Cofactor for the methylation cycle and neurotransmitter synthesis*

Other ingredients

150–200 mg

Microcrystalline cellulose, rice bran concentrate, and magnesium stearate — the flow agents and fillers that let a capsule fill consistently. No actives, no proprietary blend*

What to expect

Good from the first morning. Better by the eighth week.

Daybreak is built for daily use — some of it you feel within the hour, and some of it accrues quietly over weeks.

  1. Day 1Clean energy, no jitter

    Paraxanthine is felt at 20–40 minutes and L-theanine at 30–45, so the first capsule already lands. The difference you notice against coffee is the texture of it — a lift without the edge, and no cliff in the afternoon.*

  2. Week 2Sharper under load

    L-tyrosine's evidence is strongest when you're stressed or cognitively taxed, which is exactly when a normal morning gets hard. This is the stretch where busy days start feeling less expensive.*

  3. Week 8+A steadier baseline

    Citicoline's cognitive trials run over weeks rather than hours, and methylated B12 works as a cofactor once stores are topped up. Consistency is doing the work here, not any single dose.*

How to use

  • Take 2 capsules with water within an hour of waking.
  • Works with or without food, and alongside your usual coffee.
  • Contains paraxanthine, a caffeine metabolite — count it toward your daily caffeine if you're sensitive.

Paraxanthine, not caffeine

Same lift. Shorter stay.

When you drink coffee, your liver converts most of that caffeine into paraxanthine — so we skip the conversion and give you the metabolite directly. It hits the same adenosine receptors just as hard, so the peak is no weaker. What changes is the exit: a shorter half-life means less of it is still circulating through your afternoon, and because it bypasses the CYP1A2 step, it doesn’t hit fast and slow caffeine metabolizers differently.

Paraxanthine compared with caffeine over eight hoursBoth reach the same peak, since paraxanthine blocks adenosine receptors at least as potently as caffeine. Paraxanthine peaks slightly sooner — around 50 minutes versus an hour — and then falls away faster on its shorter half-life. By hour six roughly 34 percent of paraxanthine’s peak effect remains, against about 46 percent for caffeine; by hour eight it is 21 percent against 33 percent.012345678HOURS AFTER YOUR MORNING DOSE% OF PEAK EFFECTSAME PEAK — PARAXANTHINE IS AT LEAST AS POTENTCAFFEINEPARAXANTHINEAT 6 HOURS: 46% CAFFEINEVS 34% PARAXANTHINE
Modelled from published pharmacokinetics, not a measured clinical trial. Both curves are normalised to the same peak because paraxanthine blocks adenosine A1/A2A receptors with potency equal to or slightly greater than caffeine — the difference isn’t how strong it feels, it’s how quickly it leaves. Paraxanthine’s half-life is about 3.1 hours against caffeine’s ~4.1, and because it bypasses CYP1A2 metabolism it doesn’t swing between slow and fast caffeine metabolisers the way caffeine does.*

Why coffee hits everyone differently

How fast you clear caffeine depends on CYP1A2, and that enzyme’s activity is genetic. The result is an almost six-fold spread in how long caffeine sticks around — the same cup that wears off by lunch for one person is still working at midnight for another.

Half-life of caffeine compared with paraxanthineCaffeine’s half-life spans roughly 2.3 to 13.9 hours depending on the person, averaging about 5.4 hours — an almost six-fold spread driven by genetic differences in CYP1A2 activity. Paraxanthine’s reported half-life is about 3.1 hours, and because taking it directly skips the CYP1A2 conversion step, it isn’t subject to that same swing.CAFFEINEMEAN 5.4 h2.313.9A SIX-FOLD SPREAD, DEPENDING ON WHO YOU AREPARAXANTHINE~3.1 h — ONE FIGURE, NOT A RANGE02468101214HALF-LIFE IN HOURS
Caffeine clearance depends on CYP1A2, an enzyme whose activity varies genetically — which is why the same coffee leaves one person wired at midnight and does almost nothing for someone else. Because paraxanthine is what CYP1A2 was going to produce anyway, taking it directly skips that step. Published figures; individual response still varies.*

How to take it

Take two capsules with water within an hour of waking, with or without food. Pairs naturally with your morning coffee or tea.

    No jitters, no crash at 3pm. I still drink my one coffee but I don't need three anymore.

  • Marcus T.Verified buyer

    Took about three weeks to notice the focus difference, but it's real and it stuck.

    April 2026

  • Aiko S.Verified buyer

    Capsules are easy to take and travel well. Docking one star only because I wish the box had a 45-day supply option.

Questions

Asked and answered.

Does REZE Daybreak contain caffeine?

No — zero caffeine. Instead it uses paraxanthine, caffeine's primary active metabolite, delivered directly. It's designed to stack safely with your normal coffee or tea; since co-ingesting the two provides no extra cognitive benefit, how much coffee you drink alongside it is entirely up to you.

Why capsules instead of a drink?

The Daybreak actives are most stable — and most portable — in capsule form. Two capsules with your morning water, no mixing, no flavor to get tired of.

When will I notice a difference?

Most people feel it the same day — paraxanthine and L-theanine begin working within 20–45 minutes, citicoline and L-tyrosine over the following half hour. There's no multi-week loading period.

Can I take it with REZE Nightfall?

Yes — they're designed as a system. Paraxanthine's roughly 3-hour half-life means it clears well before evening, so there's no interference with Nightfall. Daybreak supports your waking hours; Nightfall supports wind-down and recovery.
