Why SYN?

Most recovery products wait until the morning after. SYN starts before your first drink. 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 dragging through your 9 a.m. meeting, 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. Alcohol creates acetaldehyde, which can lower the active vitamin B6 your brain uses to make melatonin. SYN gives your body active B6 before drinking while supporting your liver, hydration, sleep, and overnight recovery.

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.

“The dinner is still the meeting. I just stopped paying for it the next day.”

“I am out with clients three nights a week and the 9am is not optional. I used to build my whole calendar around what I drank the night before, and I still lost the mornings. Two capsules before the first drink, and the difference is the part of the day I get back.”

Daniel K. · M&A Associate, New York
