Counteract is not a vitamin blend or herbal extract. It's an engineered probiotic that produces the ALDH2 enzyme — the same one your body uses to metabolize acetaldehyde, the toxic intermediate behind hangovers.
It's not the alcohol. It's what comes after.

HOW IT WORKS
Deliver. Intercept. Clear. Three steps. One capsule. The same pathway your body uses — just with serious reinforcements.
Deliver — Targeted release
Enteric coating gets the capsule past stomach acid, releasing ALDH enzymes in the upper intestine — exactly where alcohol is first absorbed.
→ Duodenum & jejunum
Intercept — Enzymatic shield
ALDH enzymes activate in the gut lumen and start intercepting acetaldehyde the moment it forms — before it enters your bloodstream.
→ Target: CH₃CHO
Clear — Metabolic conversion
Acetaldehyde → acetate (harmless) → CO₂ + water. The toxic load is cleared at the source. You wake up feeling like yourself.
→ Output: acetate → CO₂ + H₂O
THE SCIENCE
Engineered at the genetic level
Precision Gene Expression
We inserted a codon-optimized ALDH2 gene into a well-characterized Lactobacillus chassis under a constitutive promoter — ensuring reliable, continuous enzyme production without induction.
Gut-Targeted Delivery
Enteric microencapsulation protects viability through gastric transit, delivering >10⁹ CFU to the duodenum and jejunum where first-pass alcohol absorption peaks.
GRAS-Status Safety
Built on a Lactobacillus platform with decades of safe human use. Contains no antibiotic resistance markers. Biocontainment features prevent environmental persistence.
Clinically Validated
In a controlled crossover study (n=82), participants showed a 2.4× increase in acetaldehyde clearance rate and 71% reduction in next-morning symptom scores vs placebo.

Four glasses of wine at dinner. Woke up at 6am, ran 5K. That has literally never happened before.

As someone with Asian flush, this is the first thing that's actually addressed the root cause.

Got questions?
Yes. Counteract uses a precision-edited Lactobacillus strain expressing recombinant human ALDH2. It is GRAS-status, biocontained, and carries no antibiotic resistance markers.
No. Counteract targets acetaldehyde — the toxic metabolite responsible for hangovers — not ethanol itself. You'll feel the same; you just won't pay for it the next morning.
Counteract was specifically designed with ALDH2-deficient individuals in mind. The supplemental enzyme provides backup capacity that the deficient native enzyme can't deliver.
One capsule, 30 minutes before your first drink. The enteric coating ensures it activates in the upper intestine just as alcohol absorption begins.
