We Are The Sleep Solution
for Peak Fitness & Healthspan
Support Your Natural Sleep Rhythms
We created a science-backed, melatonin-free sleep solution designed to support your body’s natural rhythms. Sleep isn’t just about being unconscious—it’s an active recovery process when your mind and body repair, restore, and prepare for what’s ahead. This is when your body rebuilds itself, your immune system strengthens to protect against illness, and cellular processes work to promote longevity and overall vitality.

Transform your nights into powerful recovery hours with a formula designed to do more. Our ingredients provide the essential building blocks your body needs to repair itself and include key
nutrients to optimize sleep nightly. By supporting your natural recovery processes, our solution helps enhance your near-term health and performance while promoting longevity for years to come. 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 living long, vibrant lives. For years, early-morning training sessions and jam-packed schedules were our norm. But like so many others, we often found ourselves running on fumes, struggling 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 navigating the challenges of her thriving practice. Amid the chaos, we realized our lives were all gas and no brakes. Recovery—especially quality sleep—was a major missing piece in our pursuit of long term health, mental well-being, and physical performance.
Frustrated by the lack of melatonin-free, hormone-safe options on the market, 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 enhance the brain and body’s natural overnight recovery processes. The results were transformative for us. Sleep became more than just a nightly recharge—it became a 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 busy professional, an athlete, or simply someone who wants to feel and perform at their best, we’re here to help you make sleep your ultimate ally.
