Stirling was built on a simple belief: health products should be as trustworthy as the people who recommend them. Our story most likely aligns with yours — a combination of working hard, overcoming obstacles, driving for success, and having some fun along the way.
Early Days
Every brand has an origin, but few are rooted quite as literally as ours. Stirling was founded in 2018 in Santa Cruz, California, on a stretch of farmland tucked deep within the lush, fog-draped Santa Cruz Mountains — a landscape of towering redwoods, winding coastal roads, and rich, sun-warmed soil, where Pacific mist drifts up through the ridgelines each morning before burning away into clear mountain light. It was in that quiet, verdant corner of the California coast that our founder first began experimenting with the ingredients that would come to define the company.

The name Stirling itself was almost inevitable. It first belonged to the narrow, unpaved road that led to the original farm — a name etched onto old maps long before anyone imagined a company would rise from that hillside. But rearrange its letters, and Stirling becomes Sterling: a word carrying centuries of meaning, long synonymous with high purity and uncompromising quality. Between the road that led us home and a word that has always stood for excellence, the name chose itself.
From that hillside farm, our goal was clear from the start: redefining people’s health. We looked at an industry that too often prioritized volume over integrity and set out to build something better, one product at a time.
Our mission has remained the same from day one: create thoughtfully developed products built on ingredients that are Pure. Proven. Tested. — because people deserve to live longer and happier lives, not simply endure them.
We launched during the height of the Opioid Crisis, at a time when the numbers told an uncomfortable story: Americans make up just 5% of the world’s population, yet account for over 25% of all prescriptions filled. We saw that imbalance and made a deliberate choice to build natural alternatives that could genuinely help people move away from opioid dependence and reclaim their lives. Every formula was developed carefully, without shortcuts, because people navigating that fight deserve products that actually work.
Redefining Extraction
One of the most significant developments in Stirling’s history was not a marketing decision — it was a technical one. We asked why an industry built on natural ingredients still relied so heavily on harsh chemical solvents to extract those ingredients from the plant in the first place.
Most extraction methods use butane, CO₂ under high pressure, or ethanol to strip compounds from plant matter. These methods are effective, but the result is not always as pure as the label suggests. We developed an alternative: our proprietary Solventless Extraction technology, which uses no chemical solvents at all — only ice, water, and mechanical precision.
Freezing
Organic plant matter is placed into 33°F ice water, cold enough to freeze the plant material and crystallize its structure.
33°F ice waterAgitation
The chilled mixture is passed through a 20,000 RPM impeller, generating microbubbles that collide with the crystallized matter and release the plant’s nutrients.
20,000 RPMFiltration
The resulting solution passes through a 40-micron filter, which captures the extracted compounds.
40-micron filterThe Result
A finished extract produced without solvents, added heat, or harsh chemicals.
0 solventsWe consider Solventless Extraction one of the cleanest, purest forms of extraction available today, preserving the full spectrum of the plant the way nature intended.
Growth & Challenges
Just as Stirling was gaining momentum, we faced an unexpected challenge. In late 2019, our founder and CEO, Joe Kryszak, was diagnosed with a rare and aggressive form of cancer. What followed was eight months of chemotherapy.
Rather than step back, Joe continued working throughout the treatment, developing products intended to help ease the side effects of chemotherapy. Many of those formulations, developed out of his own experience, remain among our best-selling products today. The good news is he is now in full remission.
In 2023, Stirling Professional entered its next chapter to focus solely on partnering directly with Chiropractors, Massage Therapists, and Naturopathic Providers. These professionals work directly with patients every day and share our commitment to natural, holistic solutions that address the underlying cause, not just the symptom.
Over time, Stirling has also become a recognized voice within the industry. Today, we are considered a thought leader in the supplement, topical, and cannabinoid space:
Future Outlook
Our focus on growth has not slowed, and our priorities for the remainder of this decade are clear:
Lead and educate
Continue learning alongside the industry while leading and educating healthcare professionals and professional offices as the healthcare landscape evolves.
Address root causes
Focus on the underlying biological dysfunction driving a symptom, rather than treating the symptom in isolation.
Differentiate meaningfully
Continue developing unique products with clear, substantive advantages over what is available in the mass market.
From a small idea in 2018 to a trusted voice in healthcare offices nationwide, our approach has not changed: we believe better health starts with better ingredients, and we remain committed to that standard in the years ahead.
