Premier Research Labs was founded in 1987 by clinicians Dr. Robert Marshall and Dr. Linda Forbes after a firsthand experience with supplement industry failures. Discover the founder story, sourcing philosophy and values that have driven PRL's quality-first mission for nearly four decades.
The Founder Story
Premier Research Labs was built on a simple, uncompromising belief: that quality in nutritional supplements isn't a differentiator - it's a responsibility.
Dr. Robert Marshall, PhD, CCN, DACBN, came to that belief the hard way. As a clinical nutritionist in the 1980s, he had spent years recommending supplements to clients, trusting that what was on the label reflected what was in the bottle. Then, like more than a thousand other people, he was made seriously ill by GMO-contaminated tryptophan - a product that had passed through every stage of the supply chain without anyone catching a critical lapse in manufacturing integrity. The experience was clarifying. Not because it made him cynical about the industry, but because it made him certain that doing better was entirely possible - and entirely necessary.
He and his wife, Dr. Linda Forbes, PhD, LAc, DACBN, built Premier Research Labs together in Austin, Texas in 1987 with that conviction as their foundation. Dr. Forbes brought her own deep expertise: years of research into soil health and its relationship to nutrient density, a founding commitment to sustainable and regenerative agricultural practices, and a pioneering fermentation process - what became PRL's ND-Technology™ - designed to deliver nutrients in a form the body recognizes and uses more readily.
Together, they built a company that is practitioner-first in the truest sense - founded by clinicians who understood firsthand what it meant to recommend a product and stake a client's health on its quality. Their sourcing standards, their testing protocols, their formulation philosophy, and their refusal to use non-nutritive fillers and binders all trace back to that same premise: the people depending on these products deserve better than good enough.
Nearly four decades later, PRL still operates from Austin. The portfolio has grown to more than 200 SKUs. The team has grown. But the founding question - "Does this meet the standard we would hold ourselves to as clinicians?" - hasn't changed.
Quality isn't something PRL came to through branding. It's something they built their entire operation around, because they knew from experience what was at stake when it was missing.
The Origin Story
Premier Research Labs started with something most supplement companies don't talk about openly: a firsthand understanding that quality in this industry isn't just a competitive differentiator. It has real consequences for real people.
Dr. Robert Marshall was a working clinical nutritionist in the 1980s when he, along with many others, experienced serious health effects linked to a contaminated tryptophan product. The experience didn't turn him away from the industry. It focused him. He had seen - in himself and in his clients - what happens when the supply chain fails, when testing standards are inconsistent, when the pressure to bring product to market outweighs the discipline to verify what's actually in it. He decided to build something that operated differently.
He and his wife, Dr. Linda Forbes, co-founded Premier Research Labs in Austin, Texas in 1987. Dr. Forbes brought decades of research into soil health and plant nutrition, an understanding that the vitality of a supplement begins long before manufacturing - in the quality of the soil where its ingredients are grown. Together, they built a company grounded in clinical experience, scientific rigor, and a genuine belief that doing things right was worth the extra effort.
The early years were focused on building infrastructure that reflected PRL’s quality philosophy: sourcing relationships with farmers who understood the importance of cultivation practices and ingredient integrity; testing protocols that treated every incoming lot as a new verification process rather than a routine formality; and formulation standards designed to minimise unnecessary processing aids and prioritise functional ingredient quality.
PRL has always been practitioner-focused. The company was built by clinicians who wanted to create products they could recommend with confidence - and who wanted to give other practitioners the clinical education and supporting documentation to do the same.
Nearly 40 years later, the portfolio has grown to 200+ SKUs across two brands - PRL for the practitioner channel and QNL (Quantum Nutrition Labs) for the conscious consumer market. The team has grown. Science has advanced. But the founding question hasn't changed: does this product actually do what we say it does, and can we stand behind every ingredient in it?
The Sourcing Story
PRL's sourcing standards exist because of a simple conviction: that a supplement is only as good as what goes into it, and that quality begins in the soil, not the manufacturing facility.
More than 70% of raw material candidates don't make it through PRL's evaluation process. That figure reflects the application of food-grade identity testing, multi-method purity analysis, pesticide screening, heavy metals panels, and quantum resonance evaluation - applied to every material, from every supplier, with every new lot. Not as an adversarial posture, but as due diligence on behalf of the practitioners and clients who depend on what's in the bottle.
For botanical ingredients, PRL sources from native habitats wherever possible. Plants grown in the ecosystems they evolved in carry different phytochemical profiles than those grown in depleted or unfamiliar conditions. Co-founder Dr. Linda Forbes has spent decades researching this relationship - between soil health, agricultural practice, and the nutritional quality of the crops that come from it. Her work with the Nutrition Science Foundation, and her development of PRL's ND-Technology™ fermentation process, reflects the same principle: that how a nutrient is grown and processed shapes how useful it actually is to the body.
But sourcing at PRL has always been about more than ingredient specs. The relationships PRL maintains with farmers and suppliers around the world are built on shared values - not just quality standards, but a genuine commitment to the communities and ecosystems where those ingredients are produced. PRL believes that doing business well means doing it in a way that supports the people growing the ingredients and the land they're grown on. That means prioritizing partners who practice sustainable and regenerative agriculture, who take care of their workers and their soil, and whose approach to farming reflects the same long-term thinking that informs PRL's approach to formulation.
No synthetic colorants, flavors, or coatings. No non-nutritive excipients. No irradiation of finished products. No harsh solvent extraction methods. These aren't just manufacturing standards - they're an expression of the same values that guide how PRL sources in the first place: a commitment to getting it right at every step, because what you put in matters at every step.
Values in action means making harder choices more consistently. PRL's sourcing is one of the clearest places to see that.
The Sustainability Story
For PRL, sustainability isn't a separate initiative. It's an expression of the same core values that guide everything else: that how you do something matters as much as what you do.
Co-founder Dr. Linda Forbes has spent decades studying the relationship between soil health and the nutritional quality of the plants grown in it. That research shapes PRL's sourcing from the ground up - literally. Botanical ingredients are sourced from native habitats whenever possible, because plants grown in the ecosystems they evolved in carry greater phytochemical complexity and nutritional vitality. PRL prioritizes wildcrafted and organically grown materials. Non-GMO formulations are standard across the portfolio. Synthetic colorants, flavors, and coatings are not used.
PRL's ND-Technology™ fermentation process uses natural biological mechanisms rather than synthetic chemical extraction. Finished products are never irradiated. Solvent-free extraction is the standard, not the exception. Each of these choices reflects the same principle: minimal intervention preserves more of what makes an ingredient valuable - and leaves less of a footprint on the systems that produced it.
Packaging follows suit. PRL's Violite® containers extend product shelf life by protecting nutrients from the light-induced oxidation that degrades potency over time. Longer-lasting product means less waste. Concentrated formulas mean less packaging material per effective dose. The elimination of non-nutritive fillers reduces overall product volume, which compounds over a large portfolio.
But sustainability at PRL extends into the sourcing relationships themselves. PRL works with farming and supplier partners who share their commitment - not just to quality specifications, but to the communities where those ingredients are grown. That means supporting agricultural practices that build soil health over time rather than depleting it, and it means recognising that the wellness of the people and ecosystems in PRL's supply chain matters, not just the quality of what they produce.
Building health without compromising the systems that sustain it - that's not a slogan. It's the logical extension of taking quality seriously all the way through.
