Experience True Health and Longevity

Through Quantum Nutrition


“Let Me Hear Your Body Talk!”

I am grateful and truly honored to have been trained by the late Dr. Robert J. Marshall, founder of Premier Research Labs (PRL) and developer of Quantum Research Analysis (QRA).

Advanced, Level III, Certified QRA Practitioner

Integrating my knowledge of PRL with QUEST 9 Biofeedback and Coaching Sessions allows me to customize nutrition recommendations for clients based on their specific area(s) of imbalance, weakness, infection, and/or toxicity.

Along with being the founder of Premier Research Labs (PRL) and the developer of Quantum Research Analysis (QRA)—a highly accurate and advanced form of energy testing, Dr. Marshall was an internationally trained, certified clinical nutritionist with the following experiences:  

  • President of the International and American Association of Clinical Nutritionists.

  • Member of the American Society of Tropical Medicine and Hygiene.

  • Host of Healthline, a radio broadcast which aired continuously since 1986 and networked daily in over 50 major markets across the U.S.

  • Author of numerous research papers and articles.


In the late 1960's, Dr. Marshall was unanticipatedly guided to a career in nutrition science when he contracted a near fatal illness. After numerous attempts to utilize allopathic approaches to medicine failed him, he decided to embark on a holistic healing journey. 

As it turned out, extensive research in the field of nutrition and biochemistry provided him with all the effective solutions he was so desperately searching for. It was then, Dr. Marshall began using his nutritional discoveries to provide comprehensive nutritional counselling and lifestyle programs for those wanting to experience and enjoy optimum health for themselves.


Why Premier Research Labs?

Premier Research Labs (PRL) was founded to deliver uncompromising quality and effectiveness by providing 100% non-toxic and effective products. In fact, PRL has achieved an industry first in creating premier nutritional products based on quantum cellular resonance technology. PRL products are free of undesirable chemical tag-alongs and are designed to deliver the very best quality to all that consume.

Straight from the Source: “To deliver the most consistent level of premier quality nutrition, our in-house, state-of-the-art laboratory uses chromatography technology to scan all of our raw materials to ensure they meet our superior quality standards. In addition to our standard laboratory procedures, we also screen our raw materials using our proprietary bioenergetic testing. Yes, it has been many years since PRL decided to part from the pack, and we can absolutely guarantee you that we will never knowingly use compromised ingredients in any of our products. We invite you to experience a new dimension of nutritional excellence with Premier Research Labs.”

PRL’s line of clinically tested nutritional products includes the first targeted organ and gland formulas WITHOUT animal glandulars.

A nutritional supplement designed to support each gland or tissue in the body should ideally contain a cellular resonant formulation that matches cell resonance. If natural-source nutrients are of “premier quality” (i.e. exquisitely well grown and without undesirable tagalongs), then the cell may be able to absorb both physical nutrients as well as the nutrient’s resonant frequencies, allowing the cell to function at its optimal frequency.

PRL is recognized as the world leader in cellular resonant formulations, establishing a high standard in the nutritional industry. PRL’s Quality Control Department includes an advanced, state-of-the-art laboratory staffed with scientists and a sourcing team dedicated to maintaining the high quality and integrity of raw materials that PRL products are known for—all over the globe.
