Most gut products are already dead before you take them.

That probiotic capsule on your shelf was freeze-dried months ago. Three strains in a pill, sitting in a warehouse, then shipped to your door. By the time you swallow it, most of those bacteria are gone. And the few that survive? They land in a gut already stripped by antibiotics, stress, processed food, or hormonal shifts — and they can't hold on.

That's why nothing has worked.

Your gut isn't broken. It's been drained of three things at once: the organic acids that maintain the right pH, the microbial diversity that supports your immune system, and the postbiotics that help flush excess estrogen. No capsule restores all three. Only real fermentation can.

Real fermentation is a living process. A SCOBY — a living colony of bacteria and yeast — ferments tea over weeks, producing a complete matrix of organic acids like lactic, acetic, and gluconic, alongside hundreds of microbial signals and postbiotic compounds. That matrix is the missing piece. It rebuilds the environment your gut needs before any good bacteria can take root.

Cerva captures that entire living matrix in one small daily gummy. One a day. Less than a dollar. No capsules. No yogurt. No ACV. Just real kombucha you can carry in your bag.

Take two gummies a day for best results. Most customers feel the difference within two weeks.

Kombucha Powder — Fermentation boosts polyphenol bioavailability by up to 3.87x. The organic acids produced help reduce gut wall permeability, lowering the amount of bacterial toxins reaching your bloodstream. Two human RCTs — from the University of Sydney (2023) and Georgetown University (2023) — found that kombucha blunts the blood sugar spike after meals, which directly correlates with a smaller post-meal toxin surge.

Lactobacillus Plantarum — A clinically studied strain (LP299v, multiple human RCTs) that physically strengthens the gut lining, closing the gaps that let bacterial toxins into your bloodstream. Also shown to reduce the kind of systemic inflammation that shows up as symptoms across the entire body.

Slippery Elm Extract — Forms a protective gel layer over the gut wall after meals, reducing the toxin surge that enters your blood during digestion. This directly targets why so many chronic symptoms flare up after eating.

Bacillus Coagulans — A spore-forming probiotic that survives stomach acid and reaches the gut at full strength, while standard probiotics lose up to 99% of their bacteria along the way. Supported by multiple human RCTs in the 0.8 to 2 billion CFU range.

Dandelion Root Extract — A natural potassium-sparing diuretic confirmed in a human pilot study (Clare et al., n=17) to significantly increase fluid clearance without the electrolyte crashes that make pharmaceutical diuretics hard to tolerate. Also supports liver function and antioxidant protection.
