Ubiquinol (CoQ10)
Also known as: CoQ10, reduced CoQ10, Kaneka ubiquinol.
Ubiquinol protects mitochondrial ALDH2 from oxidative damage produced by its own activity. Strong mechanistic case, no direct human hangover RCT. Tier 2 because without it, ALDH2 capacity degrades over a long night — which is exactly when you need it most.
Where this fits in the system
What it does
Ubiquinol is the reduced, bioavailable form of coenzyme Q10. Its job in the Afterburners protocol is specifically to protect mitochondrial ALDH2 — the rate-limiting enzyme for acetaldehyde clearance — from the reactive oxygen species that acetaldehyde oxidation itself produces.
How it works
Why ALDH2 needs protecting
ALDH2 lives in the mitochondrial matrix. Every acetaldehyde it clears generates reactive byproducts that damage nearby membrane lipids and, over time, the enzyme itself. During a heavy drinking session the damage accumulates faster than the cell can repair it, so ALDH2 capacity falls — exactly at the moment you most need it.
Higher-tier options in the same role
| Goal | Best (Tier 1) | Strong support (Tier 2) | Situational (Tier 3+) |
|---|---|---|---|
| Acetaldehyde clearance | DHM (Dihydromyricetin), L-Cysteine, NAC (N-Acetyl Cysteine), Sulforaphane | Ubiquinol (CoQ10) | |
| Liver protection | DHM (Dihydromyricetin), L-Cysteine, NAC (N-Acetyl Cysteine), Sulforaphane | Ubiquinol (CoQ10) |
Buying guidance
Kaneka ubiquinol is the only widely reliable source — most ubiquinol products use Kaneka's material and label it. Softgels with oil-based delivery absorb much better than dry powders.
Deep science · Ubiquinol (CoQ10) — deep dive
What ubiquinol does
Ubiquinol sits in the inner mitochondrial membrane and is a first-line antioxidant for reactive oxygen species produced at the electron transport chain. By quenching ROS locally, it reduces the oxidative load on ALDH2 and on the surrounding membrane lipids that the enzyme depends on.
Ubiquinol vs ubiquinone
Most CoQ10 supplements sell the oxidized form (ubiquinone). Ubiquinol is the reduced form and is directly bioavailable without the liver having to convert it. For an acute-use protocol, ubiquinol is worth the price difference.
