In such a vast landscape of continuing innovation and demand for supplements and vitamins (especially today, when the world has turned to a healthy lifestyle more than ever before), a few brands have managed to build the legacy and trust that Klaire Labs has achieved. Founded in 1969, the company began with a revolutionary vision of delivering clean, pharmaceutical-grade nutritional supplements, earning the trust of healthcare practitioners and patients alike. Fast forward to today, we are witnessing how Klaire Labs evolves into SFI Health US, a global leader in evidence-based natural healthcare solutions.
This transformation marks a significant milestone, but the commitment to quality, efficacy, and innovation that defined Klaire Labs’ origins remains at the core of its mission. Join us as we explore the journey of this remarkable company, its historical milestones, its rebranding as SFI Health US, and its continuing contributions to the world of natural healthcare.
This company has been around for more than half a century, not only surviving in a dense global market but putting its name in the very top of the list. Before we discuss its success, we must ask ourselves, where did it all begin?
The story of Klaire Labs begins with Claire Farr, a visionary entrepreneur who founded the company in 1969. Her motivation was deeply personal—a response to her own medical challenges and a recognition of the need for clean, high-quality supplements. At a time when fillers, synthetic ingredients, and allergens were commonplace in nutritional products, Claire set out to create a new standard.
Her single-ingredient formulations prioritized purity and bioavailability, avoiding unnecessary additives. This approach resonated with healthcare practitioners, particularly those addressing food sensitivities and allergies in their patients. By the 1970s and 80s, Klaire Labs had become synonymous with quality and trust in the medical community.
In 2004, Klaire Labs entered a pivotal phase of growth when it was acquired by ProThera, Inc., a Nevada-based company specializing in practitioner-grade supplements. ProThera’s vision aligned seamlessly with Klaire Labs’ commitment to quality, providing a unique opportunity to expand the brand’s reach while preserving its rigorous standards.
This acquisition marked a period of innovation and diversification for Klaire Labs. ProThera introduced advanced formulations, integrated complementary product lines, and leveraged its expertise in product development to broaden Klaire Labs’ capabilities. Together, the brands began addressing a wider spectrum of healthcare needs, catering to the demands of discerning healthcare practitioners who required hypoallergenic and effective supplements for their patients.
Under ProThera’s stewardship, Klaire Labs reinforced its position as a leader in nutritional supplements, with a focus on research-driven products. This partnership also laid the groundwork for the company’s future global expansion, setting the stage for its next transformative chapter.
The most significant turning point in Klaire Labs’ evolution occurred in 2013, when the company joined Soho Flordis International (SFI), a global leader in natural healthcare solutions. Recognizing Klaire Labs’ reputation for quality and its established presence in the practitioner market, SFI sought to integrate the brand into its vision of delivering evidence-based natural healthcare solutions worldwide.
The acquisition brought Klaire Labs, ProThera, and Complementary Prescriptions under the SFI umbrella, creating a powerhouse of complementary expertise and products. This move not only unified the brands but also aligned them with SFI’s global strategy, emphasizing research-backed formulations and premium quality manufacturing.
To solidify its commitment to quality, SFI made a substantial investment in a state-of-the-art cGMP (current Good Manufacturing Practice) facility in Reno, Nevada. This purpose-built facility became a cornerstone of Klaire Labs’ operations, ensuring that every product met the highest standards of safety, potency, and efficacy.
The Reno facility is equipped with advanced manufacturing technology, enabling precise control over every step of the production process—from raw material sourcing to final packaging. The facility’s focus on compliance and quality control has set a new benchmark in the industry, reflecting SFI’s dedication to delivering premium-grade nutraceuticals.
In 2014, the integration process culminated in a strategic rebranding, with Klaire Labs becoming part of the SFI Health US identity. While the brand name evolved, the core principles that defined Klaire Labs—clean formulations, practitioner trust, and scientific rigor—remained unchanged. The rebranding also provided an opportunity to highlight the company’s expanded capabilities under the SFI banner, signaling its readiness to address global healthcare challenges with a holistic approach.
As part of the SFI family, Klaire Labs has embraced a broader mission of empowering health through natural, evidence-based solutions. This evolution has enabled the company to focus on key areas such as microbiome health, cognitive wellness, and overall wellbeing, offering a robust portfolio of products tailored to the needs of modern healthcare practitioners and their patients.
