Built for the people the health industry forgot.

15 million Americans work through the night. Their gut health suffers in ways no mainstream supplement was designed to address. We're changing that.

The supplement industry is built for morning routines. For people who wake up at 6AM, take their probiotic before breakfast, and live by a normal schedule.

Nobody made anything for the nurse finishing her third back-to-back night shift. Nobody made anything for the warehouse worker eating his first real meal at 3AM. Nobody made anything for the security guard whose body doesn't know what time zone it's supposed to be in.

"I spent years trying every probiotic on the market. They all told me to take them in the morning. I work nights. My 'morning' is 2PM. None of it worked. I assumed I was just broken." — Sarah M., ICU Nurse, 7 years on night shift

Sarah isn't broken. She was using a product built for a body that follows a normal schedule — when hers doesn't. That's the gap 3AMGUT was built to fill.

The science is clear. The industry just doesn't want to talk about it.

Your gut has its own biological clock — sometimes called the "second brain." It regulates digestion, microbiome balance, and immune response on a 24-hour cycle. When you flip that cycle and work through the night, everything goes out of sync.

Bloating. Reflux. Irregular digestion. Fatigue that sleep doesn't fix. These aren't personal failures. They're predictable biological outcomes — documented in peer-reviewed research that the supplement industry has largely ignored.

We didn't ignore it. We built our formula around it.

What we stand for

01
Night-first formulation

Every ingredient, every dose, every timing recommendation in 3AMGUT is designed around a nocturnal schedule — not adapted from a 9-to-5 product.
02
Science, not marketing

We don't add ingredients because they look good on a label. Every component is backed by circadian biology research and real clinical evidence.
03
Community over profit

Night shift workers are an underserved community, not just a market segment. We price fairly, give generously, and listen constantly.
04
Radical transparency

Full label. No proprietary blends. No inflated claims. What's on the label is exactly what's in the bottle — nothing more, nothing less.

A note from the founders

3AMGUT started after watching someone we care about deeply spend years dealing with gut problems that every doctor dismissed as "just stress." She worked nights in a hospital. The connection was obvious once we learned the science — but nobody had built a solution for it.

We're not trying to be the biggest supplement company. We're trying to be the most useful one for people who work while the rest of the world sleeps. The nurses. The paramedics. The warehouse workers. The bakers. The security guards. The overnight teams.

You keep the world running. Your gut health deserves to keep up with you.
