Here’s something both sides of the hangover-prevention aisle agree on: waiting until the morning after is too late. Whether it’s a pear juice or a capsule, the products that actually have research behind them all work the same way — you take them before you drink, not after. That’s not a marketing gimmick, it’s a pharmacology fact. Alcohol-processing enzymes need a head start.
So the real question isn’t "does a pre-drink ritual work" — it’s which pre-drink ritual fits how you actually live. Below is an honest look at the two most-discussed options: whole Korean pear juice (what Gush is made of) and DHM (dihydromyricetin) capsules, the ingredient behind several supplement-aisle competitors.
How each one actually works
Korean pear (Pyrus pyrifolia). The pear itself — not an isolated extract — contains compounds including arbutin, chlorogenic acid, and quercetin. A 2013 human crossover trial (PubMed) found that drinking Korean pear juice 30 minutes before alcohol reduced total hangover severity by 16% and average severity by 21%, with the clearest improvements in concentration, memory, and light/sound sensitivity. Because it’s the whole juice, you also get real hydration and electrolytes alongside the enzyme-support effect — alcohol dehydrates you regardless of what pre-game ritual you use, and a capsule can’t do anything about that part.
DHM (dihydromyricetin). DHM is a flavonoid sourced from Hovenia dulcis, the Japanese raisin tree — a different plant from Korean pear entirely, despite sometimes getting lumped into the same conversation. It has its own body of research, including randomized, placebo-controlled human trials, and appears to work primarily by interacting with GABA-A receptors in the brain. It's a real, studied compound, delivered in a capsule, with one job. One real edge it has: because it works through a different pathway than enzyme-priming, it doesn't strictly require pre-loading — some people take it during or after drinking, not just before. Whole pear juice doesn't have that flexibility; the enzyme-support effect only works if it's already in your system before alcohol is.
Choose Korean Pear Drinks if:
You want a refreshing, 100% natural pre-drink ritual. It is ideal if you easily remember to prep your stomach before your first alcoholic beverage. You'd rather drink something that also hydrates you than swallow a pill that only targets one enzyme pathway. You like being able to see and taste what you're putting in your body, ingredient by ingredient.
Choose DHM Capsules if:
You want something you can drop in a bag or pocket with zero prep, no fridge, no can to pack out. You're traveling and liquids are a hassle. You're already taking other supplements and prefer to stack a capsule into that routine rather than add a drink. Flavor and hydration aren't priorities for you — you just want the enzyme-support mechanism, nothing else. And you'd rather not add extra liquid volume or fruit sugar to your night before you've even started drinking.
Make it a ritual, not an afterthought
The products don't fail because the science is weak — they fail because people forget to take them before they start drinking. That's the actual habit to build: same time you're getting ready, same spot by your keys or your door, one can, every time you know you're heading out. A ritual you'll actually repeat beats a perfect product you forget to use.
You'll start seeing hybrid products that blend pear juice with concentrated plant extracts to engineer a bigger number on the label. We've kept Gush simple on purpose: real Korean pear, nothing added to hit a target dose.
Our stake in the ground: a pill can activate an enzyme. It can't rehydrate you. Gush does both.
