Dr. Kendal Stewart, M.D. / Founder and Medical Director

Dr. Kendal Stewart serves as the current Chief Science Officer (CSO) for GX Sciences, Neurobiologix, and Dr. Neurobiologix. He’s also a member of the American Academy of Anti-Aging Medicine. In addition, he founded and serves as Chairman for the Neurosensory Centers of America.

Dr. Stewart graduated from the University of Texas at Austin with a BA in Biology with Honors as well as a minor in Chemistry. He graduated with a Medical Doctorate from the University of Texas Medical School, where he also received a Distinguished Student of Clinical Medicine Award for the class of 1988. He served as a biomedical research assistant under Takahashi Yamora, PhD, in the Department of Biochemistry and Molecular Biology at MD Anderson Cancer Institute. There, he researched biochemical analysis of surface protein markers in colorectal cancers.

Dr. Stewart completed his residency at University of Texas Houston Affiliated Hospitals and MD Anderson Cancer Institute. During his residency, he received multiple awards, including the Outstanding Clinical Resident Teaching Award in 1993 and the Outstanding Resident Research Award & Scholarship from the Texas Medical Association/Texas Association of Otolaryngology in 1992. He was explicitly selected for a highly sought-after Fellowship in Otology and Neurotology - Skull Base Surgery at Baylor University Center in Dallas. During this time, he also served as a Clinical Adjunctive Professor.

Dr. Kendal Stewart is a Board-Certified Otolaryngology/Head and Neck Surgery specialist and has sub-specialty training in Otology and Neurotology - Skull Base Surgery. He served as a Clinical Associate Professor at the University of Texas Medical School at San Antonio’s Department of Otolaryngology from 1994 to 1996. He’s been tapped to speak at national conferences over 40 times as a result of his expertise. Additionally, Dr. Stewart has volunteered his time for numerous academic pursuits, including assisting in designing Masters and Doctorate candidate projects for the University of Texas Department of Kinesiology, Psychology, and Speech and Language Development, as well as assembling a patient database for these efforts. He has also participated in two doctoral candidate review boards at the University of Texas.

Dr. Kendal Stewart's Work With Supplement Formulation

As a leading expert in Neuro-sensory Disorders, Methylation, and Genetic Polymorphisms, Dr. Stewart has encouraged all practitioners to learn the biochemical pathways necessary to objectively verify their patients’ nutritional needs. But, with contemporary advances to genetic testing and nutrigenomic testing in particular, the efficacy and necessity of supplemental nutrition has been scientifically corroborated and validated.

With the experience of treating thousands of patients and reading thousands of genetic reports, Dr. Stewart surmised that nutritional supplementation ought to be carefully constructed for each individual. This belief provided the seed for the idea of Neurobiologix. Dr. Kendal Stewart, together with investors, formed Neurobiologix, Inc. to provide the highest quality supplementation available while cutting costs for the consumer. By combining the specific supplements that belong together biochemically, Neurobiologix is able to restrict most people’s supplementation to just a few unique, exclusive formulations.

Neurobiologix is committed to public health and safety; to that end, various safety considerations have been implemented in Neurobiologix’ manufacturing chain. Our supplements are exclusively manufactured in facilities certified for Good Manufacturing Practices (GMP) by both the Natural Products Association and the National Science Foundation in order to meet the highest quality standards.

From Dr. Stewart...Practicing medicine didn’t have the right approach to taking care of people

"I quit operating completely once I realized I could do a much better job of making people feel good before they got sick."

"For me what’s really shaped my career more than anything has been a transition in the way we take care of people. Starting in 2005 I quit operating completely once I realized I could do a much better job of making people feel good before they got sick."

"When genetics came around in late 2013 and early 2014, we saw a major transition. The machines we used to have to use for genetic interpretation were large, cumbersome and expensive. But then the machines shrank significantly. With this major change we can now look at an individual and address any issues, and hopefully avoid major medical issues that you would have had to typically deal with retroactively."

"Today, using a cheek swab, we are able to use genetics to look at what nutritional elements may be weak and at a person’s mitochondria and battery of cells. We’re able to proactively overcome a lot of those weaknesses, and maintain health in a whole, better way. We can customize and tailor specific needs based on you alone rather than on say, a group of patients that have this medical condition."

"Now we can actually strengthen the immune system, and see who’s at risk and work to keep them from getting the disease in the first place. It’s completely transitioned the way we practice medicine. So instead of cutting people open, we’re better at reviewing genetics and much more successful at providing them a quality life."

"With GX Sciences (formerly Genomix nutrition), which we founded in April of 2016, we are actually able to address upfront a major weakness your body has, and overcome it. We call it precision medicine."
