What you'll feel the very next morning

SYN works overnight. You don't wait weeks to notice, you notice at your first alarm.

🧠

A clear head

No fog, no "one step behind." You think at full speed in the meeting that matters.

😴

Real sleep

SYN protects your deep sleep, so eight hours in bed actually feels like eight.

Steady energy

Wake up level instead of drained. No crash, no second coffee to function.

🌅

Like yourself

The person who walked into dinner is the person who walks into the 7 a.m.

Take it. Forget it. Own it.

Taking SYN before drinks
30 minutes before

Take it

Two capsules with water before the first drink. If you can remember to charge your phone, you're qualified.

Drinks out with friends
While you drink

Forget it

The formula works while you drink. No app, no tracking, no powder mustache.

Up and moving the next morning
7:00 am

Own it

The alarm hits the same. So do you. Clear head, steady energy.

Most brands promise the moon. We'd rather keep it honest.

It won't stop you getting drunk. Nothing does. Anyone who says otherwise is selling snake oil.
It won't "cure" a hangover. Nobody can honestly say that word.
Protects sleep & recovery: helps guard the deep sleep and overnight recovery alcohol wrecks, so you wake up clear, not foggy.
Puts back what's lost: refills the active vitamin B6 that alcohol drains overnight.
Backs up your liver: milk thistle and plant extracts support it while it breaks down every drink.
Works before, not after: two capsules, 30 minutes ahead, so you're protected when it matters.
Founder's note

"I built SYN because my calendar didn't care how last night went. No one in this space has a big study on sleep science yet. So we tell you exactly what the science shows, and we're working to fund that study. Honesty beats hype anyway."

— Justin Zuo, Co-founder, SYN

It's not magic.
It's sleep & recovery.

Everyone blames the drinks. The real thief is what they leave behind.

Alcohol becomes acetaldehyde

As your body breaks down alcohol, it first turns it into acetaldehyde, a harmful chemical that's actually harder on your body than the alcohol itself.

It steals your sleep vitamin

Acetaldehyde drains your active vitamin B6, the helper your brain needs to make melatonin. No helper, no deep sleep.

Your deep sleep falls apart

The deep part of your sleep, the part that recharges you, falls apart. You sleep all night and still wake up feeling like you got four hours.

SYN steps in — before the first drink

Two capsules, 30 minutes ahead. B6 refills your sleep helper, L-theanine keeps you calm, and milk thistle backs up your liver. It's all working before the damage, not after.

Based on published research on how acetaldehyde lowers active vitamin B6. See the science

The Overnight Recovery Protocol

Most products do one thing. SYN does three, each at a different point in your night.

REM Defense

Protect your sleep & recovery

Alcohol drains the helper your brain needs to make melatonin. SYN puts it back, so eight hours of sleep feels like eight, and your body actually recovers overnight.

Why it matters: the morning fog is mostly a sleep problem. Nobody else is talking about it.
The Pre-Load Window

Get there before the damage

Morning-after products show up when the damage is done. The window that works is before: SYN loads your body with what it's about to lose.

Why it matters: before isn't a detail. It's the whole point.
Liver Support

Back up the cleanup crew

Your liver breaks down every drink, all night. Milk thistle and six plant extracts support it while it works.

Why it matters: your liver doesn't get a night off. On big weeks, neither does SYN.

What does a lost morning cost you?

The real bill: the re-read email, the meeting you nodded through, the sharp comment you didn't have. SYN costs about as much as the tip on one client dinner.

Why SYN?

Most drinks-recovery products try to clean up the mess the morning after. SYN works before your first drink instead. Two capsules, 30 minutes ahead, help protect the deep sleep alcohol normally wrecks. That deep sleep is the real reason you wake up foggy. It won't stop you getting drunk, and it won't "cure" a hangover. What it does is put back what a big night takes out, so tomorrow still belongs to you.

Benefits

Clearer mornings, deeper sleep, steadier next-day energy, and less of the fog that usually follows a night out. Instead of dragging through your 9 a.m. on four hours of real sleep, you show up as the same person who sat down to dinner.

Ingredients & allergies

Ingredients
Each serving (2 capsules) contains: L-Theanine 200 mg, Milk Thistle Extract 120 mg, Andrographis Extract 38 mg, Chicory Seed Extract 38 mg, Grape Extract 38 mg, Date Palm Extract 38 mg, Phyllanthus 25 mg, Amla Extract 25 mg, and Vitamin B6 (as P5P) 20 mg — plus electrolytes (Sodium 10 mg, Potassium 13 mg, Magnesium 18 mg). Other ingredient: vegetarian capsule (HPMC).

Allergies
SYN is vegetarian, non-GMO, and gluten-free. If you're pregnant, nursing, trying to conceive, on medication, or managing a health condition (including autoimmune conditions), talk to your doctor before taking it.

How to take it

Take two capsules with water about 30 minutes before your first drink. That head start is what lets everything be in your system before the alcohol is. Repeat each time you drink. No powders, no mixing, no morning routine. The travel case keeps a dose in your jacket for when a dinner runs long.

Science & certifications

SYN is made in a GMP-certified, FDA-registered facility and tested by an outside lab. The mechanism is based on published research: acetaldehyde, which is what alcohol becomes in your body, drains the active vitamin B6 your brain needs to make melatonin. SYN puts that helper back before the drop happens. We describe how the ingredients work, not guaranteed results, so try it on your own mornings.

Shipping & returns

Free shipping on every order, and subscriptions ship on the schedule you choose. Skip, pause, or cancel anytime in two clicks. Every box is backed by the 30-Night Sharp Morning Guarantee: if your mornings don't improve, email us for a full refund and keep the box, the case, and the playbook.

You probably have some questions

Check out our FAQs below, and reach out any time if you have more.

All FAQs
Who is SYN actually for?

People whose calendar doesn't care how last night went — founders, operators, dealmakers, anyone with 2–4 work dinners a week and a 9 a.m. that matters. If your nights are optional but your mornings aren't, that's you.

Does it actually work?

The science behind how it works is published. That's why the 30-Night Guarantee exists: try it on your own mornings.

Do I have to drink less?

No. Take it before, keep the table. SYN works with your evening, not against it. (We'll never be the brand wagging a finger at you.)

When and how do I take it?

Two capsules with water, about 30 minutes before your first drink. Repeat each time you drink. The travel case exists so they're in your jacket when the dinner runs long.

Is it safe?

Made in a GMP-certified, FDA-registered facility and third-party tested. Talk to your doctor first if you're pregnant, nursing, trying to conceive, taking medication, or managing a health condition (including autoimmune conditions). Not a substitute for responsible drinking — it does not prevent intoxication or impairment.

How does the subscription work?

Your box ships on the schedule you pick, with free shipping. Skip, pause, or cancel anytime from your account in two clicks. Your discounted rate stays locked while your subscription is active.

What's the guarantee, exactly?
