RefluxRaft is an all-natural, alginate-based formula that helps support”temporary symptoms of reflux by forming a protective barrier, or "raft," on top of your stomach contents. This helps keep acid and digestive enzymes from traveling up into the esophagus, so you feel more comfortable, without altering your body's natural stomach acid levels. The raft starts forming within minutes of taking it and lasts up to four hours.*

Made from sodium alginate, a natural fiber derived from kelp, RefluxRaft comes in three formulas — Lemon Ginger, Berry Burst, and Midnight Berry PM — so there's an option whether you need daytime or nighttime support. 

If you want the deeper mechanism explanation (what alginate is and how the raft actually forms), check out The Science, or start with Reflux 101 if you're newer to how reflux works in general. Not sure which formula is right for you? Take the two-minute quiz.*

Unlike PPIs, which reduce acid production, or antacids, which neutralize acid, RefluxRaft works differently: it creates a physical barrier that helps offer temporary relief from symptoms related to  reflux in the first place. It starts working right away, doesn't alter your stomach's acid levels, and involves no systemic absorption.*

Both work! Many people take RefluxRaft as needed for occasional discomfort, while others build it into a daily routine after meals and before bed for steadier, more consistent support — and consistency tends to matter more than any single dose, especially if you're using it to help with LPR or nighttime symptoms.

RefluxRaft's protective barrier starts forming within minutes of taking it, and can last up to four hours depending on our digestion and meal size.

RefluxRaft works best after eating, since it forms its barrier on top of stomach contents. Taken on an empty stomach, it can still help coat and soothe the esophagus, though the full raft-forming effect may be reduced.*

We always recommend checking with your doctor or pharmacist for guidance tailored to you. They'll be able to advise on the best routine for your particular situation.

RefluxRaft works differently than antacids or PPIs: it forms a physical, alginate-based barrier on top of your stomach contents rather than being absorbed into your system, so it shouldn't interact negatively with what else you're taking.

That said, if you take everything at the exact same time, it's possible that the raft could temporarily sit on top of other things in your stomach and slightly delay how quickly they're absorbed. If you'd rather play it safe, a simple habit is to space RefluxRaft about 30–60 minutes apart from other medications or supplements.

A few timing notes:

• RefluxRaft works best when taken after meals and/or before bed, up to four times a day, as needed.
• Try to avoid food and water for at least 15 minutes after a dose, so the protective raft has time to form.
• Midnight Berry PM contains 1mg of melatonin, so if you're already taking a sleep aid or supplement with melatonin, keep that in mind when timing your dose.

This information is for general guidance only and isn't a substitute for medical advice.

Yes. Laryngopharyngeal reflux (LPR), also known as silent reflux, happens when stomach contents — acid and the digestive enzyme pepsin — travel past the esophagus and reach your throat and voice box. That tissue doesn't have the same natural defenses your esophagus does, so even small, brief episodes can lead to real irritation, and often without the classic heartburn people associate with reflux.

RefluxRaft's alginate barrier is designed to help keep acid and pepsin from traveling that far up, which is why people dealing with LPR often reach for it for support with symptoms like:

• A sore or scratchy throat
• Hoarseness, or a voice that fades throughout the day
• Chronic throat clearing or a cough that won't quit
• A lump-in-the-throat feeling
• Post-nasal drip

Because LPR can look a lot like allergies or a lingering cold, it's easy to miss for a while — only a doctor or ENT can actually diagnose it. If the pattern above sounds familiar, our Silent Reflux (LPR) guide goes deeper into how it differs from typical GERD and why acid-reducers alone don't always fully address it.
