Meet Dr. Bob Marshall

by Optimum Nutrition Admin

Dr. Robert Marshall - founder of Quantum Nutrition LabsEarly in life, Bob Marshall focused his analytic mind on the technically advanced engines of high performance racing cars.  From these mentally and physically challenging beginnings, he dedicated himself to maintenance and improvement of the most complex engine of all – the human body.  However, it was not until a life threatening illness that required the development of his own life-saving treatment that Dr. Marshall began focusing on chronic illness and the naturopathic products and procedures to restore ideal health and cellular resonance.  Founder of Premier Research Labs and Quantum Nutrition Labs, Dr. Bob Marshall is a certified, internationally trained clinical nutritionist, past president of the International and American Association of Clinical Nutritionists and member of the American Society of Tropical Medicine and Hygiene.   He has operated one of the largest chronic illness practices in Southern California for many years.   Currently his main activities include overseeing Quantum Nutrition Labs’ manufacturing, as well as writing and teaching his “Quantum Reflex Analysis” techniques to healthcare professionals in seminars throughout the United States.

Dr. Bob Marshall maintains clinical facilities in Torrance, California and Round Rock, Texas, where he continues to test and refine new and existing formulations.  His companies, Quantum Nutrition Labs and Premier Research Labs, provide consumers and health professionals with full lines of nutritional, body care and lifestyle products that work synergistically to achieve and maintain optimal health.  Quantum Nutrition Labs and Premier Research Labs have clinically developed products by working together with medical doctors, chiropractors, nutritionists and other health professionals to produce functional food/herb phytonutrient products that embody “Nutrition That Really Works.”  Dr. Marshall delivers uncompromising quality using unwavering standards of excellence to ensure extraordinary product purity.  He has developed, clinically tested and proven the effectiveness of each of its cutting edge nutritional formulas. Dr. Marshall’s mission is: “to empower every person to access their own limitless healing potential through the use of resonance nutraceutical formulations, spectacular detoxification techniques and premier therapeutic strategies.”

Long-time Quantum Nutrition customers have undoubtedly experienced several back-order situations of their favorite products over the years. The occasional unavailability of particular product is always due to the shortage of a high quality ingredient, which is certainly frustrating for the customer. However, it is further evidence that Dr. Marshall does not accept anything less than the energetically and nutritionally strongest raw materials for his formulations. Instead of using a substandard ingredient for easy, expedience and continued sales, Dr. Marshall rather incur the revenue loss until the supplement can be produce at its highest level of efficacy.

Dr. Marshall has been the host of the wildly popular HealthLine Live, a radio broadcast aired continuously since 1986 and is currently heard in over 15 states.  You can benefit from Dr. Marshall’s nutrition and health expertise first hand by listening to his Healthline Live Radio show airing on a station in your area or streaming live on the web.  Dr. Bob offers insightful health information in addition to answering callers’ health-related questions from around the country.  If you have been plagued by a condition that traditional medicine has been unable to resolve, consider tuning in or actually calling the program.  To get a listing of showtimes, click here.  If the HealthLine Live show is not being carried by your local radio stations, many of the stations that are in the HealthLine network simulcast on their websites or you can go to for a rebroadcast.  The CRN schedule is:

    Two years ago I started experiencing chronic dry eye. Doctors plugged the ducts to keep moisture from draining away from the eye then I was put on Restasis. Nothing worked. I didn’t want to suffer with the misery of dry eyes any longer so I decided to take things into my own hands and researched supplements that claimed to help. I came across Dr. Bob Marshall and Quantum Nutrition Labs and decided to give Eye Support a try. I’m not kidding when I say I’m no longer on any prescription medications and my eyes don’t bother me. I’m a believer in Quantum Nutrition Labs and Dr. Bob Marshall’s views on holistic healing. I’m very grateful.

    Diagnosed with benign thyroid (follicular) nodule. Endocrinologist recommending Radio Active Iodine which will kill the thyroid. Are there any holistic option left for me?

  3. lee cory May 31, 2014 at 12:28 am

    In a follow question about my thyroid nodule, I have read all the Naturalistic doctors books and newsletters and they said can shrink the nodule with a raw diet. Is that possible?

  4. Optimum Nutrition Admin May 31, 2014 at 2:15 pm

    To say whether a raw diet would have any effect on any abnormal tissue mass without muscling testing the person specifically for their condition and appropriate treatment is irresponsible and based on egotistical ignorance. While a raw diet is the only truly healthful way to eat, it is unlikely that you would be able to eat the foods necessary (or in the correct portions) simply by chance to substantially impact the thyroid. However, a raw diet will improve overall health by lessening the burden on the digestive system and increasing the amount of nutritional intake.

  5. Optimum Nutrition Admin May 31, 2014 at 2:33 pm

    Absolutely. However, you must find a competent, experienced healthcare practitioner who can not only accurately muscle test but understands the right questions to ask and is aware of the most effective treatments available. Very few people are able to accurately muscle test and fewer still understand how to use it.

    I started to listen Dr. Marshall about10 years ago; I’ve used his miracles, and blessed products all this time; and know that I’m still alive because of that; living a joyful life full of energy. There are lots of more things to say, but no space, thank you Dr. Marshall.

    I thank God for Dr. Marshall and Quantum Nutrition Labs. I had a severe bladder infection for a very long time. Even after eliminating the infection, I was left with a bladder so weak I couldn’t last an hour before having to run to the bathroom. Because of this condition, I never could get a good night’s sleep. My bladder would always feel full and I would be up and down all night. After taking 3 capsules three times a day of Bladder Support for a few months, I only get up once to go to the bathroom and sometimes not at all. For the first time in years I am rested!!!

    How can I find out what supplements will work specifically for what my body needs?

  10. Optimum Nutrition Admin July 12, 2017 at 2:37 pm

    In terms of general nutrition, everyone needs the same nutrients (vitamins, minerals, essential fatty acids, etc.), it is the amounts that will vary. Applied kinesiology (muscle testing) is really the only way to accurately determine dosages. A person can learn to do this themselves (Muscle Testing 101) or find an experienced practitioner.
