The complete guide to relief from spicy food: what stops the mouth burn, what calms your stomach, and why everything before Sooz only did half the job.
By the Sooz team · Updated July 6, 2026
Spice relief, also called spicy food relief, is the reduction or elimination of the burning sensation and digestive discomfort caused by capsaicin, the compound in chili peppers responsible for the heat response. When you eat spicy food, capsaicin binds to TRPV1 pain receptors on your tongue and travels through your digestive system, triggering a burning response at every stage.
Complete relief from spicy food covers all three stages: the mouth burn you feel immediately, the stomach acid and gastric irritation that follow during the meal, and the next-morning digestive consequences that spicy food enthusiasts know too well. Most people only think about the first one, and that's exactly why most spice relief options fall short.
The short version: Capsaicin is fat-soluble, not water-soluble. Water doesn't wash it away; it spreads it. Real spicy food relief requires ingredients that bind to capsaicin, buffer your stomach acid, and cushion your gut. Sooz has all three.
If you love spicy food, you already know the trade. You either grit through the burn, the heartburn, and the rough morning after, or you quietly order things milder than you actually want. Most people just accept that as the cost of eating the food they love.
It doesn't have to be a trade. The whole point of real spice relief is that you stop choosing between the meal you want and feeling fine afterward. Get the mechanism right at all three stages and the heat goes back to being the fun part, with none of the tax. That's the bar Sooz was built to clear, and the rest of this page explains how it gets there.
Every popular remedy for spicy food has a real mechanism, from milk to antacids to the home remedies your group chat swears by. The problem is that each one only targets one stage. Here's how the common spicy food remedies stack up across all three:
| Remedy | Mouth burn | Stomach acid | Morning gut |
|---|---|---|---|
| Milk or yogurt | ✓ | ✗ | ✗ |
| Water or beer | ✗ (makes it worse) | ✗ | ✗ |
| Bread or rice | ~ | ✗ | ✗ |
| Antacids (Tums, Pepto) | ✗ | ~ (reactive) | ✗ |
| Fiber supplements | ✗ | ✗ | ~ |
| Sooz | ✓ | ✓ | ✓ |
Capsaicin is fat-soluble, not water-soluble. When you drink water after eating spicy food, you are not washing the capsaicin away. You are spreading it around your mouth, exposing more TRPV1 receptors to the compound and often making the burn feel more intense. The same is true for beer, juice, and soda.
Water only helps spice relief when it is carrying something that can actually do the work, like the casein protein, citrate acid buffer, and psyllium fiber in Sooz.
If your mouth is burning right now, here is what helps with spicy food, in order of how well it works:
One catch: all of these only help the burn in your mouth. The capsaicin you already swallowed is still headed for your stomach and gut, which is what the next sections are about.
Milk is the most effective folk remedy for mouth-stage spice relief because it contains casein, a protein that binds to capsaicin molecules and physically removes them from your TRPV1 receptors. Whole milk works better than skim because the fat content also dissolves some capsaicin (fat-soluble compound, fat solvent). Ice cream works for the same reason.
But milk's spice relief only goes as far as your mouth. It does nothing for the stomach acid ramp-up that capsaicin triggers, nothing for the gastric irritation, and nothing for next-morning gut consequences. It is also awkward to sip alongside Thai curry or Nashville hot chicken.
Sooz delivers the same casein mechanism as milk, via sodium caseinate, in a portable powder sachet you mix with water. And it adds two more targeted ingredients for the stages milk misses.
If your stomach is burning after eating spicy food, the cause is usually the extra acid your stomach produces in response to capsaicin, on top of the direct irritation of your stomach lining. That is why spicy food heartburn shows up an hour after the meal, long after your mouth has calmed down. The remedy at this stage is an acid buffer: sodium citrate (the buffering agent in Sooz) or, reactively, an antacid.
There is no dedicated medicine for spicy food. Antacids like Tums are the closest thing, but they are reactive: you take them after the burning has started, and they do nothing for your mouth or for the next morning. The more effective pattern is prevention. Drinking Sooz during the meal puts the acid buffer in your stomach before the capsaicin arrives, so the acid spike gets neutralized as it happens instead of treated afterward.
For an upset stomach or stomach ache the morning after spicy food, the reliable remedy is soluble fiber taken with the meal. Psyllium husk lines the gut and cushions capsaicin's path through your intestines before it can irritate them. Once the morning has already gone wrong, hydration and time are the honest answer, and Sooz with your next spicy meal is the fix that keeps it from happening again.
Sooz is a three-ingredient system that intercepts capsaicin at every stage of the spicy food experience. Each ingredient was chosen for a specific mechanism:

None of this is guesswork. TRPV1, the pain receptor capsaicin activates, was identified by Caterina et al. in a landmark 1997 Nature paper. Nasrawi & Pangborn (1990) found that dairy proteins measurably cut capsaicin mouth-burn while plain water did not, and Nolden, Lenart & Hayes (2019) later confirmed milk beats water, soda, and beer head-to-head. Psyllium husk's gut-cushioning effect is documented in McRorie & McKeown's 2017 review of fiber physics in the gastrointestinal tract, and citrate ion's role as a stomach-acid buffer is recognized in the FDA's own OTC antacid monograph.
