We Are The Sleep Solution
for Peak Fitness & Healthspan
Support Your Natural Sleep Rhythms
Life today pushes your body and mind to the limit. Long hours, stress, blue light, and intense workouts deplete neurotransmitters, spike cortisol, and make deep, restorative sleep harder to achieve.
But sleep isn’t just being unconscious—it’s when your body actively repairs, restores, and prepares for what’s ahead. Cellular processes rebuild muscles, strengthen tendons, and restore your immune system, supporting long-term health and fitness.
Without the right nutrients, your nervous system, brain, and muscles can’t fully recover—leaving you depleted instead of restored.
Maximize Your Nighttime Recovery
Thirdzy helps you get the deep, high-quality sleep your body needs to actually recover—without melatonin or sedatives.
Our formula replenishes what a go-go life depletes with key amino acids, minerals, and calming compounds. These nutrients lower stress hormones, support neurotransmitters, and provide the building blocks for overnight muscle repair.
Instead of just “knocking you out,” Thirdzy works with your body’s natural recovery processes-so you wake up refreshed, restored and ready to perform physcially and mentally.
By fueling recovery, Thirdzy enhances daily performance and supports long-term health. Because sleep isn’t just the foundation of recovery—it’s the cornerstone of thriving.
A Note from our
Co-Founders
A Note from our
Co-Founders
We’re a husband-and-wife team with a shared passion for fitness, health, and longevity. Early-morning training and jam-packed schedules were our norm, but like many, we often ran on fumes trying to balance it all.
In 2020, everything changed. Adam was deep into his demanding career in investment banking, while Justine, a doctor of chiropractic, was running her thriving practice. Amid the chaos, we realized our lives were all gas, no brakes. Recovery—especially quality sleep—was the missing piece in our pursuit of long-term health, mental well-being, and peak performance.
Frustrated by the lack of melatonin-free, hormone-safe options, Justine took matters into her own hands. Leveraging her expertise in nutrition and biochemistry, she formulated a custom blend of key nutrients and amino acids to optimize overnight recovery. The results were transformative. Sleep became our superpower, fueling our days and training with enhanced energy and remarkable clarity.
We founded Thirdzy to help other busy people unlock the power of healthy, natural sleep. Whether you’re a professional, an athlete, or simply want to feel and perform at your best, we’re here to help you make sleep your superpower too.
Here’s to restful nights and unstoppable days,
