Take it

Take one capsule with water about half an hour before your first drink.

Forget it

It keeps working while you're out. You don't have to think about it again.

Own it

The alarm goes off and you're ready for it, with a clear head and steady energy.

Missed the 30-minute window? Take it as soon as you remember.

The drinks end.
Their effects don't.

You drank the water. You slept eight hours. You still woke up feeling wrecked. That feeling is the reason we built SYN.

It is not just being tired

The fog. The slow start. That feeling of being a step behind when the day has already begun. A big night can cost you more than the sleep you missed.

Your liver has a long night too

Your liver keeps working through every drink long after you have gone to bed. SYN supports normal liver function while it does.

Your sleep can take a hit

Alcohol can help you fall asleep fast. But as your body clears it, your sleep gets lighter and you wake more often. It can also cut into REM sleep, the dreaming stage of the night.

Why we built SYN

One capsule before your first drink. It supports your liver, your gut and a good night's sleep. Made for people who have to be fully on the next day: the morning meeting, the school run, the early flight.

Protect tomorrow

Not just big nights. Any night you drink.

Why SYN?

SYN starts before your first drink, not the morning after. Take one capsule 30 minutes before drinking to support restful sleep, hydration, your liver, and overnight recovery. It won't stop you from getting drunk or cure a hangover. It supports your body while you drink and through the night, so you can wake up clearer and better rested.

Benefits

Clearer mornings, more restful sleep, steadier energy, and less morning fog. Instead of writing off the morning, you can think clearly and show up like yourself.

Ingredients & allergies

Ingredients
Each serving (1 capsule) contains: L-Theanine 150 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 Electrolytes + B6 (baseline) 23 mg. Other ingredient: vegetarian capsule (HPMC).

Dietary information & warnings
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 one capsule 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. There's nothing to mix and nothing to do in the morning.

Science & certifications

SYN is made in a GMP-certified facility registered with the FDA and tested by an independent lab. Every dose is printed on the label and there are no proprietary blends, so you can check exactly what you are taking. See the Supplement Facts.

Shipping & returns

Subscriptions include free shipping and ship on the schedule you choose. Skip, pause, or cancel anytime. Shipping for one-time orders is calculated at checkout. Your first order is covered by a 30-day guarantee. If you're not happy with it, email us for a full refund and keep the box and playbook.

Before the first drink. Working through the night.

A note from our team

"We built SYN because our calendars 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. We'd rather be honest about that than hype it."

Frequently Asked Questions

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

All FAQs
Who is SYN for?

Anyone whose mornings still have to happen. A wedding, a work trip, a birthday, a Friday that ran long: if you drink some nights and need the next day anyway, that's you.

Does it work?

Research supports the individual ingredients and biological pathways behind SYN. Every dose is printed on the label, and the best test is your own next morning.

Do I have to drink less?

No. Take it before, and enjoy the night as you planned it. SYN is meant to fit your evening.

When and how do I take it?

Light night out: one capsule with water, about 30 minutes before your first drink. Heavy night out: take two.

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.
