The hangover remedy market is built on a flawed premise: that meaningful intervention is possible after the damage has already been done. Here's why the science points in the other direction.
What's Already Happened by Morning
By the time you wake up with a headache, a dry mouth, and a mind full of regret, your body has already been through most of what's going to happen. Acetaldehyde accumulated and was (partially) cleared. B-vitamins were depleted and excreted. Electrolytes were lost. Oxidative stress peaked and began resolving.
The morning-after symptoms you're experiencing are largely the aftermath of processes that completed hours ago. Trying to address them at that point is like trying to prevent a fire by pouring water on the ash.
The First 30 Minutes Matter Most
Acetaldehyde — the primary toxic byproduct of alcohol metabolism — begins accumulating within 20–30 minutes of your first drink. This is when the liver's enzyme systems are working hardest, when oxidative stress begins to build, and when the demand for glutathione and B-vitamin cofactors is highest.
If you want to support your body's metabolism of alcohol, this is the window. Not the next morning. Not mid-evening when you're already a few drinks in. Before.
Why "Taking It During" Doesn't Work Either
Some products recommend taking supplements mid-drinking, when you first start to feel effects. By this point, acetaldehyde has already been building for some time. More importantly, alcohol impairs gastric absorption — the bioavailability of orally taken compounds decreases as blood alcohol rises.
Taking Reeva after you've started drinking is better than not taking it at all. But taking it before — when your digestive system is fully functional and your enzyme systems aren't yet under strain — gives the active ingredients the best possible conditions to work.
The Prevention Model
Reeva is built on a simple premise: your body responds to alcohol in a predictable, sequential way. Support that sequence at the beginning, not the end.
One jelly, taken before your first drink. It doesn't eliminate alcohol from your life or make you impervious to its effects. It gives your body's natural metabolic machinery what it needs to do its job more efficiently — before the process begins.
That's not a marketing claim. It's a timing decision backed by the underlying biochemistry.
