"I was constantly ruined by hangovers — no matter how little I drank, I never felt good the next day. Friends said it was 'just part of getting older.' But after trying Kiyoi, everything changed. I can actually go out on Fridays now, wake up clear-headed, and get on with my weekend. Finally feel like myself again after a night out."

Kiyoi Japanese Herbal Blend — Naturally Blocks Hangovers To Help You Feel Your Best The Next Day

Title

We've all been there. Last night was fun. This morning? Not so much. You're lying in bed, head pounding, stomach churning, swearing you'll never drink again. Sound familiar?

 

Here's the thing - hangovers aren't "just part of drinking." They aren't "the price you pay" or something that "gets worse with age."

 

Take one sachet of Kiyoi before your first drink and tomorrow morning feels like those days again when hangovers never happened.

 

It helps your body process alcohol properly so hangovers never even start.

 

No hangover = nothing to cure. No more googling 'hangover cures' still in bed at 11AM the morning after.

Wake up feeling totally normal - no headache, no puking

Sleep soundly through the night instead of waking up desperate for water

Avoid the crippling anxiety and weird guilt about what you said last night

Your brain actually works in the morning (imagine that)

What Makes Kiyoi Different?

Most "hangover cures" try to fix the damage after it's done. That's like trying to uncrash your car.

 

Kiyoi works differently - it's taken BEFORE you drink. It gives your body what it needs to process alcohol properly in the first place, so the hangover never even happens.

 

Think of it like this: Those other products you've tried are band-aids. Kiyoi is prevention.

 

Plus, it's from Japan where after-work drinking is basically expected. They figured this out decades ago. If it works for people who drink with coworkers every night, it'll work for you.

How Does It Actually Work?

The simple version: Alcohol creates toxins that poison you from the inside. That's what causes your hangover.

 

Kiyoi's ingredients help your body break down alcohol faster and clear out those toxins before they build up.

 

Key nutrients:

🍄  Cordyceps - Speeds up alcohol breakdown 

🌱  Inulin - Protects your gut from getting wrecked 

🍇  Red Grape Leaf - Flushes toxins out faster 

🍊  Hesperidin - Stops inflammation before it starts

 

Take it before drinking, and your body handles the alcohol instead of getting overwhelmed by it.

When Do I Take It?

Take one sachet right before your first drink.

 

Most people make it part of the night - everyone at the table takes their Kiyoi sachet, does a little "pre-cheers" with them, then downs the powder and washes it with water or soda. After that, it's on with the real drinks. Takes just 3 seconds and you're good for the night.

 

You could take it earlier if you want, but honestly, doing it together at the table makes sure nobody forgets.

Will This Work For Me?

If you drink alcohol and get hangovers, Kiyoi works for you.

 

Works for:

Any age (as long as you drink)

Beer, wine, spirits, cocktails, seltzers - any alcohol

Light drinkers or heavy drinkers

Every time you drink

The only people it won't work for are those rare people who never get hangovers (lucky them) or anyone who forgets to take it before drinking.

Our No-Hangover Promise

Your order is protected by our 90-day guarantee. If Kiyoi doesn't prevent your hangovers, or if you're not satisfied for any reason, just reach out within 90 days. We'll refund your full purchase price.

Alcohol Takes a Serious Toll on Your Body

Remember when you could drink without consequences? Now even a few drinks leave you wrecked the next day. You're not imagining it - hangovers really are getting worse.

 

Every time you drink, alcohol turns into toxins that poison your liver, brain, and gut. And here's the thing - as you get older, your body makes less of what it needs to break down those toxins. That's why the same drinks that were fine years ago, wreck you now.

 

Most people accept this as "just part of getting older." They skip social events. Say no to drinks at dinner. Miss out on fun because they know tomorrow will be hell.

 

The real problem: Your body can't handle alcohol like it used to. Toxins build up all night. You wake up with that pounding head, sick stomach, the "what did I say?" anxiety, and your entire day wasted recovering.

Kiyoi: The Japanese Solution That Replaces What You've Lost

Remember what your body used to produce naturally? The nutrients that broke down alcohol properly? Kiyoi gives it back to you.

 

For decades, people in Japan have taken these herbs before drinking to prevent hangovers entirely. They figured out which natural nutrients help your body process alcohol - even when it's not making enough on its own anymore.

 

Kiyoi's 8 essential nutrients do what your body used to do naturally:

Speeds up alcohol breakdown (like it used to happen)

Protects your gut from damage

Stops inflammation before the headache starts

Flushes out toxins before they build up

 

Here's the difference: Instead of accepting that hangovers are "just part of getting older," you take one sachet of Kiyoi before drinking. Your body gets what it needs. The alcohol toxins never build up. You wake up normal.

 

No more skipping events. No more saying no to drinks at dinner. No more entire days wasted recovering.

 

Take Kiyoi and drink without consequences again.
