For the 2 a.m. crowd

Still waking up at 2 a.m. — even on your acid blocker?

Reflux runs on two clocks — a daytime meal clock and a nighttime acid clock. One pill can't be in the right place at both times. That's why reventide is two formulas: a DAY drink and NIGHT capsules. Not to replace your pill — to cover the hours it was never in the room for.

✓ A physical raft on top of your biggest meal — not another acid pill
✓ Valve and lining support while you sleep, right before the nighttime acid peak

Why you wake up at 2 a.m. with acid in your throat

You do everything right. You stop eating by 7:30. You sleep on your left side. The wedge pillow has been there for years. You still take the pill every morning — and the nights are still bad.

Here's what most people are never told: acid production has a clock. It peaks between 10 p.m. and 2 a.m., right when you're lying flat and gravity stops helping. That's why the burning finds you in the dark, even when the daytime feels manageable.

Why you wake up at 2 a.m. with acid in your throat

It was the drug's rhythm — not your body failing

A morning pill is at its weakest exactly when the nighttime acid peak begins — that's the drug's rhythm working against your body's. If stopping the pill made everything worse, that isn't weakness or a broken body. It's a documented rebound: in a randomized trial, 44% of adults who stopped a PPI after 8 weeks developed acid symptoms — versus 15% on placebo (Reimer et al., Gastroenterology, 2009). Acid-producing cells wake up more active for a while after long-term suppression.

And the natural things you may have tried — DGL, apple cider vinegar, slippery elm — didn't fail because natural doesn't work. They failed because every one of them was a capsule you swallowed whenever. Your reflux doesn't happen whenever. It happens on top of a meal, and it happens while you're lying flat. A capsule taken at breakfast is in neither room.

What that means for you. Nobody is asking you to stop your pill — that's a conversation for you and your doctor, and the guide in your kit walks you through how to have it. What you can do is stop leaving those two windows unprotected. The morning pill was never in the room after dinner, and it was never in the room at 2 a.m. That's the gap you've been living in for years, and it's the only gap this system was built for. Start there. Then have the conversation from a stronger position.

The part no one told you

Reflux runs on two clocks

The reflux you feel happens around meals during the day. But your body makes the most acid on a separate schedule — a nighttime rhythm that peaks while you're lying flat and asleep. One pill, taken once, can't meet both.

Daytime meals — the reflux you can feel Nighttime acid peak, ~10 p.m.–2 a.m.

Illustrative. The nighttime acid peak around 10 p.m.–2 a.m. is described in circadian research (e.g. Moore & Englert, Nature, 1970).

Day clock

Daytime: a barrier on the meal that starts trouble

Meals are when the valve is challenged and acid gets pushed where it doesn't belong. The DAY drink sets a physical alginate raft on top of your largest meal — a barrier at the moment it's needed — plus a DGL dose for the lining.

Night clock

Nighttime: valve + lining while you sleep

Lying flat removes gravity, and acid peaks. The NIGHT capsules support the tone of the valve overnight and deliver the bedtime lining dose — zinc-L-carnosine and L-glutamine — right before the acid peak.

The 3-Layer Reflux Reset

Three jobs, split across day and night

Three layers of support, timed to reflux's two clocks: a barrier, valve support, lining support. What's new is the timing — each layer runs at the moment it matters, with lining support landing morning and night.

1

Barrier

Day formula · after meals

Layer 1 · Barrier

Stirred into water right after your largest meal, the alginate reacts with stomach acid and sets into a floating gel raft on top of what you just ate — a physical barrier at the exact spot reflux starts. The calcium carbonate and sodium bicarbonate buffer acid on contact and give the raft its lift.

Sodium Alginate 1,000 mg + carbonate buffer Ingredient research: Leiman et al., 2017 (pooled analysis, 14 trials, n=2,095)

2

Valve support

Night formula

Layer 2 · Valve + clock

Not the sleep hormone here — the sphincter hormone. Supports the tone of the lower esophageal valve overnight and the nighttime acid rhythm. Taken at bedtime, so it's in the NIGHT formula only.

Melatonin 2.7 mg Ingredient research: Kandil 2010 — melatonin at 3 mg in one small clinical study (n=9 per group).

3

Lining support

Day + Night

Layer 3 · Lining support

Zinc-L-carnosine binds preferentially to worn tissue and supports the lining's natural integrity, with L-glutamine — the gut lining's primary fuel — alongside it overnight. DGL rides with the day raft, so lining support lands morning and night.

Zinc-L-Carnosine 135 mg + L-Glutamine 900 mg (night) · DGL 500 mg (day) Ingredient research: Mahmood et al., 2007 (Gut) — zinc carnosine, studied in healthy adults for intestinal lining integrity.

You just saw why one pill can't cover both windows

The 90-day protocol is the one built to match the guarantee.

Three kits. One DAY pouch and one NIGHT bottle each — enough to cover both windows, every day, for the full 90 nights the guarantee runs.

The alginate barrier: 14 randomized trials, 2,095 patients (Leiman et al., 2017)

One drink, two capsules — that's it

Your new routine, start to finish

No wedge to prop up, no antacids to ration. A quick drink after your biggest meal, two capsules before bed — each doing its job at the time it matters.

Morning

After your largest meal

DAY stick pack in water

Stir one stick pack into a small glass of water and drink it right after the meal that usually starts trouble. The raft forms on top of what you just ate.

Through the day

Eat like a normal person

The barrier did its job at the meal. No melatonin on board, so no midday drowsiness.

Before bed

2 NIGHT capsules, ~30 min before sleep

Valve support kicks in and the overnight lining dose lands — right before the acid peak.

Overnight

Lie flat again

The support you were missing works while you sleep, through the 10 p.m.–2 a.m. window.

Bedtime

Consistency matters more than exact timing. Same two moments each day works best.

Dosed to the research

How the formula works across 90 days

The raft is immediate and physical. The valve and lining side is dosed over weeks — the way the studies ran it.

Day 1 — the barrier is physical

The DAY drink sets its raft within minutes of your largest meal. That part isn't gradual — it's chemistry.

Weeks 1–8 — the valve window

Melatonin has been studied for lower-esophageal-valve tone in one small clinical study running eight weeks (Kandil et al., 2010). Research on the ingredient, not on our finished product.

Nightly, across the 90 days — the lining window

Zinc-L-carnosine and L-glutamine are dosed every night; the lining research they're drawn from used sustained daily dosing (Mahmood et al., 2007).

Day 90 — the conversation you've been putting off

Ninety nights of data, not a hunch. That's what you bring to your doctor when you talk about what comes next — and it's the window the guarantee covers, which is why the 3-kit protocol is built to match it.

Nothing hidden

Every milligram, printed. No proprietary blends.

If a formula hides its doses behind a 'blend,' it's usually because the doses are too small to matter. We print every one, exactly as it appears on the label. Tap any ingredient for what it does and the research behind it.

Day formula

Sodium Alginate (from brown seaweed) 1,000 mg

What our customers say

Real nights, in their words

4.8 · 1,800+ reviews

The first couple of weeks I noticed I wasn't reaching for the antacids at 2 a.m. anymore. I still keep a roll in the nightstand out of habit, but that drawer has stayed shut for a while now. I take the night capsules right before bed and mostly forget about them until morning.

Diane R. Ohio

I've done the wedge pillow, the no-food-after-7 rule, all of it. The nights were still rough even on my morning pill. About six weeks in and I'm staying asleep more nights than not. It's not every single night, but it's a different baseline than I've had in years.

Karen M. Florida

Honest review: the first ten days I didn't notice much and almost gave up. Somewhere in week two it started to click. Now most nights are calm. It's not overnight, so don't expect that — but it's the first thing that's actually stuck for me.

Priya N.

What sold me was the label. Every dose printed, nothing hiding behind a 'proprietary blend.' I've thrown money at formulas that never told me how little was actually in them — this is the first one where I could check the math. Three months in and the mornings feel steadier.

Customer photo

Greg T. Texas

I was nervous about adding anything to a stomach that was already unpredictable, so I eased into it. A few weeks in, the after-dinner heaviness isn't the whole-evening event it used to be. Not a magic switch — but I've stopped dreading dinner. One star off because I'd prefer the drink a little less minty.

Customer photo

Sandra P.

My reflux always spikes during my worst work weeks and I never understood why. This is the first thing that seems to hold up even when things get stressful. The packet goes into a glass of water after lunch, the capsules live on the nightstand — and I mostly don't think about it in between, which is the whole point.

Customer photo

Marcus L. California

Mine never really looked like classic heartburn — more of a throat thing, the constant clearing. I read a lot before buying and liked that every dose is printed right on the label instead of a 'blend.' A couple months in and mornings are noticeably easier. Still early for me, but I'm sticking with it.

Customer photo

Nina S.

My wife and I both started it. After years of keeping antacids on both nightstands, that's just not our routine anymore. We're sleeping flatter than we used to. Wish we'd found something like this ten years ago.

Customer photo

Robert & Jean Arizona

Bought the 6-kit after the first month convinced me. Works out cheaper per day than the antacids I was buying anyway, and I'm not chewing chalk in the dark at 2 a.m. Simple math.

Tom H.

The small thing that got me: I had a real cup of coffee in the morning without bracing for what it'd do to me later. Haven't been able to say that in a long time.

Ingredient research

Sodium Alginate (barrier)

A 2017 meta-analysis of 14 randomized trials (2,095 patients) found alginate-based therapies were significantly more likely to resolve reflux symptoms than placebo or antacids (odds ratio 4.42). Day Shield uses the same alginate salt — sodium alginate — at 1,000 mg per stick. Those trials dosed several times a day.

Leiman et al., 2017 — Diseases of the Esophagus

Zinc Carnosine (lining support)

In a randomized, placebo-controlled trial, a zinc-carnosine complex helped support intestinal lining integrity in healthy adults exposed to a common gut irritant. Night Restore provides 135 mg of zinc carnosine per serving.

Why we built this

We built the thing we couldn't find

We got tired of two kinds of reflux products: pharmacy shelves that only muted the symptom, and supplement bottles that hid tiny doses behind a 'proprietary blend.' So we built the opposite — one system for reflux's two clocks, with every milligram printed on the label. No celebrity, no hype. Just the version we wanted for the people we care about.

The reventide teamFounders, reventide

The honest answers

Questions people actually ask

Why a drink AND capsules instead of one pill?

Because reflux runs on two clocks — and the two jobs need two different forms. Right after a big meal you want a physical raft sitting on top of the food, and only a powder stirred into water can spread and gel there within minutes. Overnight you want valve and lining support released slowly while you sleep — that's a capsule's job. One pill, taken once, can't do either job at the right time.

Can I take this alongside my prescription?

Many people use it as day-and-night support alongside their prescription. Talk to your doctor first — especially with proton pump inhibitors, immunosuppressants, or sedatives — and any change to your medication is a decision for you and your doctor, not for us. This is a dietary supplement, not a drug.

Can I just take the Night formula?

You can, but you'd lose the barrier. The NIGHT capsules support the valve and the lining while you sleep — the DAY drink is the part that physically sits on top of your biggest meal and catches trouble where it starts. The system is built as a whole: raft by day, repair by night.

I already take melatonin for sleep. How is this different?

Different job, different dose, different timing. Sleep doses are often 5–10 mg and aimed at your brain. Here it's a smaller, GI-focused 2.7 mg in the NIGHT formula to support the tone of the lower esophageal valve and the nighttime acid rhythm — not to knock you out. There's no melatonin in the DAY formula at all. If you already take melatonin, talk to your doctor before combining.

What does the DAY drink taste like — isn't mint a reflux trigger?

It's a light natural mint, sweetened with stevia, and it mixes clear into 3–4 oz of water. Mint tea and mint candy show up on trigger lists because they relax on the way down — here the alginate raft is already forming as you drink, which is a different situation. That said, everyone's triggers are their own: if mint is a hard no for you, take that into account.

Why is there calcium and sodium in the DAY formula?

They're not filler — they're how the raft forms. Alginate needs acid plus carbonate and bicarbonate to set into a floating gel, so the calcium carbonate and sodium bicarbonate are working parts of the barrier. One stick pack carries 336 mg of sodium (about 15% of a day's value). If you're on a sodium-restricted diet, or you're pregnant or nursing, talk to your doctor before starting — being upfront about that matters more to us than a sale.

How soon might I notice something?

The raft forms within minutes of drinking it, so the barrier side can work from the first dose. The valve and lining side is the slower part — most people give it the full 90 days, which is exactly what the guarantee covers. Individual experiences vary.

What does the guarantee cover, and how does it ship?

90 days, full money-back, empty bottles included — pouch and bottle — and we cover return shipping. Free shipping on every order.

Tired of this being your normal?
