How does NightRaft work?

After dinner, a pocket of acid floats at the very top of your stomach. When you lie down, it can slide up toward your throat. NightRaft's sodium alginate, from brown seaweed, turns into a soft gel when it meets stomach acid, and bicarbonate makes that gel float like a raft over the acid pocket, helping keep stomach contents where they belong while you sleep.* Melatonin supports restful sleep.*

How do I take it?

Tear open one stick after dinner or 30 minutes before bed and swallow the gel. One stick a night, that's it.

Can I take it with my acid pill?

Yes. NightRaft doesn't block acid production: it works in a different way, on top of your routine. Keep taking what your doctor prescribed and don't stop a medication without talking to them.

How quickly will I notice a difference?

Alginate rafts form within minutes of reaching your stomach. Most people give NightRaft 2 to 4 weeks of nightly use to judge their nights. That's why every order comes with our 60-day money-back guarantee.

Who should not take NightRaft?

Not for use during pregnancy or breastfeeding, or by anyone under 18 (it contains melatonin). It contains sodium, so ask your healthcare provider if you follow a low-sodium diet. It may cause drowsiness: don't drive after taking it.

Made for the night. Nothing you don't need.

Why it burns when you lie down

Nighttime reflux isn't just too much acid. It's acid that rises.

After dinner, a pocket of acid floats at the top of your stomach, right under the door to your throat.

How NightRaft works: a seaweed raft floats over stomach acid while you sleep

Standing up, gravity keeps that acid pocket down. Lie down, and it can slip up into your esophagus: the burn, the sour taste, the cough at 3 a.m. Antacids neutralize for a short while, and acid pills make acid weaker, but neither keeps it from rising. NightRaft forms a soft floating raft over the acid pocket, to help keep stomach contents where they belong while you sleep.*

1. The raft forms

Sodium alginate from brown seaweed turns into a gel when it meets stomach acid. Bicarbonate and calcium make it float and hold together.

Sodium alginateBicarbonateCalcium

2. You sleep

The raft sits over the acid pocket while you lie down, and melatonin supports restful sleep.*

Melatonin 3 mg

One stick a night. No acid blocking. Works alongside your routine.

What's inside

A seaweed raft and the night hormone.

No proprietary blends, no 'root cause' herbs. Just what research supports.

NightRaft ingredients: sodium alginate, sodium bicarbonate, calcium carbonate, melatonin
The raft

Sodium Alginate

A natural fiber from brown seaweed that forms a soft gel raft over the acid pocket after meals.*

In a review of 14 clinical studies (2,095 people), alginate-based products were about 4 times more likely than placebo or antacids to relieve heartburn symptoms.

Makes it float

Sodium Bicarbonate

Releases tiny bubbles in the stomach so the alginate gel rises to the top and floats like a raft.

Holds it together

Calcium Carbonate

Helps the alginate gel set into a firmer, more stable raft.

The night hormone

Melatonin (3 mg)

Made by your brain at night, and by your gut too. Supports restful sleep and nighttime digestive comfort.*

In a randomized, placebo-controlled study, people with reflux symptoms who added 3 mg of melatonin to their usual treatment reported less heartburn than with placebo.

Study results refer to individual ingredients, not to the NightRaft formula.

Why nothing has worked so far

Most fixes work on the acid. NightRaft works on the night.

If you've tried Tums, acid pills and a wedge pillow and you still wake up burning, here's why.
