What's in Sooz?

Three ingredients. One for each place spicy food gets you: your mouth, your stomach, and the next morning.

Active Ingredients

1

Casein

The milk protein, without the milk

You've probably reached for milk after a spicy meal at some point. It works because of proteins like this one. We just put it somewhere more convenient.

2

Sodium Citrate

The antacid

A buffering agent that neutralizes excess stomach acid triggered by spicy food. It helps prevent that post-meal acid reflux and stomach burn that capsaicin loves to cause.

3

Psyllium Husk

Gut armor

Spice doesn't stop being spicy just because you swallowed it. Psyllium husk is a fiber that lines your gut and helps cushion the ride on the way out. Your toilet will thank you.

Backed by Published Research

Every ingredient in Sooz targets a mechanism that's already been studied independently — not just something that sounded good. Here's the published research behind each one.

  1. Capsaicin binds to TRPV1 pain receptors on the tongue and oral mucosa, which is why spicy heat registers as pain rather than temperature. Caterina MJ, et al. "The Capsaicin Receptor: A Heat-Activated Ion Channel in the Pain Pathway." Nature, 1997. View study →
  2. Rinsing with dairy proteins measurably reduced capsaicin mouth-burn, while plain water did not — part of why casein, not water, is the basis for mouth-stage relief. Nasrawi CW, Pangborn RM. "Temporal Effectiveness of Mouth-Rinsing on Capsaicin Mouth-Burn." Physiology & Behavior, 1990. View study →
  3. In a controlled head-to-head test of common beverages, milk outperformed water, soda, and non-alcoholic beer at reducing capsaicin's oral burn. Nolden AA, Lenart TA, Hayes JE. "Putting Out the Fire: Efficacy of Common Beverages in Reducing Oral Burn from Capsaicin." Physiology & Behavior, 2019. View study →
  4. Soluble, gel-forming fibers like psyllium husk physically coat and cushion the gastrointestinal tract as they pass through it — the mechanism behind using psyllium against next-day digestive irritation. McRorie JW, McKeown NM. "Understanding the Physics of Functional Fibers in the Gastrointestinal Tract." Journal of the Academy of Nutrition and Dietetics, 2017. View study →
  5. Citrate ion is a recognized over-the-counter antacid active ingredient for neutralizing excess stomach acid — the regulatory basis for using sodium citrate against capsaicin-triggered acid production. U.S. FDA. Over-the-Counter Monograph M001: Antacid Products for OTC Human Use. View monograph →
