Px Coffee

ABC. Adios to acidity. Bye to bloat. Ciao to caffeine.

Regular coffee isn't always kind to your tummy. You love the ritual and the energy — but your gut pays the price. It shouldn't have to be that way.


The culprit? Caffeine. It can stimulate your gut, stomach acid, and nervous system far more than you might realize.


At Rarebird, we listened to our bodies, took the same coffee you love and replaced caffeine with Px, what our bodies turn caffeine into. Px provides all of the energy and focus boost you'd expect from caffeine, but it's gentler on your body so you can boost focus and concentration without worrying about the caffeine consequences.

Why Px Coffee is better?

Low acid premium quality beans

No caffeine-driven stomach acid spikes

Less smooth muscle overstimulation

And its always freshly roasted

Making a true difference

No more caffeine rollercoaster.

There's no doubt about it: Coffee is essential to our daily routines. But traditional coffee has caffeine, and caffeine comes with downsides.


You get about 30 minutes of free energy before the jitters and brain fog kick in. Then there's the afternoon cup or the afternoon crash. Both affect the rest of your day and ultimately... your sleep. It's frustrating to feel dependent on caffeine just to function.


What if coffee could be smarter? No more jitters... No more crashes...  Only smooth, consistent, reliable energy.

After years of research, Rarebird has created the first and only Px Coffee. Using patented technology, Rarebird replaces caffeine with Px—an ingredient that naturally occurs in your body, but is typically overshadowed by the side effects of caffeine. Rarebird is the only coffee that allows you to experience the benefits of Px on its own.


Px kickstarts your day without triggering cortisol and adrenaline spikes, so you can have sip throughout the day, staying energized and focused, avoiding midday slumps and crashes and still sleep soundly at night.


With Px, you can stop worrying about caffeine and simply replace it with something better.

Rarebird's Story

"Like millions, I relied on caffeine to get through the day—until I realized it was a crutch. Instead of giving me energy, it left me anxious and burned out. When I couldn’t find a better alternative, I was forced to make one. Px Coffee was born from a simple idea: energy should work with your body, not against it."


- Jeffrey, Founder & CEO

Better health through coffee

Afternoons

Sleep

Px's more efficient metabolism means energized afternoons, relaxed evenings, and better sleep, even when enjoyed later in the day.

Hormones

Control

No cortisol or blood pressure spikes means you can sip throughout the day and stay focused and in control—because you want to, not have to.

Anxiety

Stress

Multiple studies have shown Px to be anxiolytic (reducing anxiety), while a 2024 study found caffeine to be likely to actually increase anxiety.

Quality

Mold-Free

We strictly procure sustainably harvested specialty grade, single-origin coffee and test for mold and mycotoxins.

WIRED not... Wired 

"Honestly, I felt many of the positive effects after my first cup. I felt focused and got a lot of work done, certainly more than I would have if I didn’t have any coffee at all, and I got absolutely none of the heart-racing, jittery feeling I do with regular coffee. Even if you drink a lot of this, you’re not going to feel cracked out, but your attention span will likely increase. It’s a weird biohack, but it works. Another bonus—I didn’t feel it rush through my digestive system as I do with regular coffee, if you know what I mean."


— Andrew Watman, Wired
