Who is Dr. Marshall, PhD?

Robert J. Marshall,PhD, CCN, DACBN, is the radio talk show host of “HealthLine Live”, a dynamic daily radio show that has aired continuously since 1986 and is currently networked in over 50 different markets in the U.S. He has shared his nutritional insights and discoveries with many radio audiences across the nation for over 30 years.

Dr. Marshall is also the CEO and founder of Quantum Nutrition Labs (QNL), a premier nutrition company that delivers quantum quality nutritional products. QNL products are the preferred choice of many thousands of people across the U.S.


A Death Sentence

Earlier in his life, Dr. Marshall was faced with imminent death from an incurable illness. Given only one year to live and sent home to die, he instead adopted a “never say die” attitude and began intensive research, relentlessly searching for the genuine “super” quality nutrients written about in the ancient texts. 


So what happened, did he die?

No!  He was able to slowly regain his health. Armed with his new nutrition discoveries, he founded Quantum Nutrition Labs (QNL) to offer help to anyone in need. He conceived of QNL to launch a new class of quantum quality nutritional formulas, meticulously designed to deliver the “Quantum Nutrition Effect” – quantum-state nutrients without added excipients or other questionable ingredients. He made his QNL formulas with specific nutrients that could elegantly support various organs and glands of the body. 

Dr. Marshall went on to operate one of the largest nutrition practices in southern California and has been in clinical practice for over 30 years. Currently, his main activities include hosting the “HealthLine Live” radio show, overseeing the operations of QNL, continuing his clinical nutritional research, teaching nutritional seminars and working with clients on a limited basis. 


Can I see Dr. Marshall as a Client?


Yes. Dr. Marshall and his staff work with clients at his office located in Santa Monica, CA. He individually designs each of his client’s nutritional programs by combining cutting-edge nutritional science and Quantum Reflex AnalysisSM (QRASM), an elegant method of integrating clinical nutrition and bio-energetic analysis of traditional acupuncture organ/gland control points to pinpoint the specific needs of each individual. 

For those who have been unable to find solutions elsewhere, Dr. Marshall has a proven track record of providing nutritional answers to help a broad range of health concerns.  Call 310-320-1132 ext. 3 for more information.
