Acetaldehyde accumulation
Acetaldehyde is the first and most damaging product of ethanol metabolism. It is a Group 1 carcinogen and the molecular cause of most hangover symptoms. Every ingredient in the Afterburners protocol exists, directly or indirectly, to reduce it.
What is happening
The metabolic pipeline
Ethanol → (ADH) → acetaldehyde → (ALDH2) → acetate → (TCA cycle) → CO₂ + H₂O.
The first step is fast. The second step is the bottleneck. Acetaldehyde sits in the middle, waiting for ALDH2 to clear it, and its concentration climbs whenever ADH feeds it faster than ALDH2 can drain it.
Ingredients that address this, ranked
- L-Cysteine Tier 1 · Core Impact: high — Chemical trap for acetaldehyde at the source.
- NAC (N-Acetyl Cysteine) Tier 1 · Core Impact: high — Glutathione precursor; acetaminophen safety net.
- DHM (Dihydromyricetin) Tier 1 · Core Impact: high — Accelerates alcohol clearance; blunts GABA rebound.

Why it is so reactive
Acetaldehyde has an electrophilic carbonyl carbon that readily forms covalent adducts with nucleophiles in the body:
- Proteins — attacks lysine ε-amines, producing Schiff bases
that crosslink hepatic proteins.
- DNA — forms N²-ethylidene-deoxyguanosine adducts (the
carcinogenic mechanism).
- Glutathione — depletes the tripeptide that normally quenches
electrophiles, undermining the backup defense.
How the protocol attacks it
The four-layer architecture maps directly to acetaldehyde handling:
- Layer 1 — chemical trap. Sacrificial nucleophiles that
compete with endogenous proteins for the electrophilic carbon. L-cysteine is the strongest.
- Layer 2 — enzymatic acceleration. Raise ALDH2 activity.
DHM and sulforaphane.
- Layer 3 — liver infrastructure. Protect the hepatocytes and
glutathione pools that everything else depends on. NAC, silymarin.
- Layer 4 — symptom resolution. Manage the downstream
consequences — sleep, pain, nausea — when Layers 1–3 don't fully contain the exposure.
