Treating root causes, not just symptoms.

For nearly 25 years, The Biologix Center for Optimum Health has been healing people with treatment-resistant chronic illness, or symptoms that persist for longer than 3 months. Using extremely precise and scientifically advanced alternative treatments and therapies, our doctors seek to treat the root causes of illness by promoting the functional integrity of the entire human person, thereby restoring the body’s ability to heal itself.

Biologix has succeeded in helping thousands of people from around the world who have exhausted conventional medicine treatments—and often alternative medicine treatments—with what was essentially incurable, or at least non-responsive chronic illness. Our initiative of treating the underlying causes of disease as opposed to just its symptoms has resulted in thousands of success stories. We look forward to adding yours.

What independent Doctors Say about Dr. Jernigan’s Innovations

“Please let this letter serve as our recommendations for how important Dr. David Jernigan and Phagen Corp’s, INPT Technology are and their potential for changing healthcare. The science of Induced Native Phage Therapy (INPT) far surpasses any other healthcare therapies to date. We cannot express enough the profound impact these technologies could have on the practice of medicine. Especially with the increase in Diabetes, Auto-Immune diseases, and antibiotic resistance, just to name a few. We look forward to further advances in this technology and their benefits to mankind.”

Dr. S.C., ND., PScD, ThD.

It is one thing to read about his work and to understand its promise from a theoretical perspective. It is an entirely another thing to experience it firsthand. The accuracy of his approach is utterly mind-blowing. From a research perspective, I am in awe of what is possible with his work.” 

Dr. C.M., PhD

I congratulate Dr. David Jernigan for his outstanding research in the use of phages to treat and in some cases eliminate harmful microorganisms such as Lyme bacteria. Jernigan invented a completely unique way to activate or induce specific beneficial phages that live inside the body called Induced Native Phage Therapy.”

Dr. M.O., MD

BRILLIANT and highly valuable piece of work.”

Dr. G.H., PhD

“In my opinion the revolutionary Phage Therapy Dr. Jernigan has developed could potentially negate the need for antibiotic treatment in many patients. In addition, INPT may be a major part of the solution to the ever-growing antibiotic resistance as reported by the World Health Organization. This therapy could save the lives of millions of hospitalized patients who are fighting septicemia and septic shock caused by antibiotic resistant bacteria.

The science Dr. Jernigan has discovered and developed is a new class of health care technology that will potentially cause a significant paradigm in the practice of medicine. The published peer-reviewed research, laboratory results, and clinical outcomes are evidence that these new innovations are some of the most advanced technologies in healthcare to date. In my opinion Dr Jernigan’s research and development of INPT may someday be considered for a Nobel Prize in Medicine and Physiology.”

Dr. M.S., MD

“I have been a colleague of Dr. David Jernigan for many years and know him ot be a man of integrity. We have discussed his research on several occasions and Ihave read his published reports about Biospectral Emission Sequence testing and Induced Native Phage Therapy (INPT) It in my opinion that the frequency medicine he has developed could very well replace antibiotics, anti-viral, and anti-fungal meds, as well as be used in many ways to replace other outdated ways of treating. This work is hugely important to continue advancing. Any support that can be given to him to continue his work should be paramount in light of the epidemic of antibiotic-resistant superbugs!”

Dr. T.L., DDS, NMD

I have been following Dr. David Jernigan’s research and published reports concerning his innovations, including Biospectral Emission Sequence (BES) testing and Induced Native Phage Therapy (INPT) and I must say that the science he has discovered is a new class of health care technologies that has the huge potential to change the way that medicine is practiced, improve health outcomes, and save many millions of lives. The published peer-reviewed research, laboratory results, and clinical outcomes is evidence that these new innovations are potentially some of the most advanced technologies in healthcare to date. This work is so revolutionary and original (to my knowledge) that his work could be worthy of nomination for the Nobel Prize in Medicine and Physiology.”

Dr. P.T., MD

A Message From Doctor Jernigan

A Message from Dr. David Jernigan

“If you have to keep taking something forever, even a natural supplement, to function, it’s not fixing the bottom-line issues. Once those issues are identified and corrected, you should be able to stop treatment. The body is the carpenter that repairs, eliminates, and restores health. Therapies are the tools the body uses. True healing requires both the right tools and the body’s ability to use them effectively.” 

— Dr. David Jernigan, Founder

“The body is the carpenter that must do the work of repairing, eliminating, and restoring true health. The treatments and therapies are the nails, screwdrivers, saws, and hammers that the carpenter needs to be able to use to do the work. The carpenter (your body) must be able to do the work in order for the quality of life you seek can be achieved.

Pharmaceuticals are most often only creating the drug-induced illusions of health, which is why you cannot get off of them without the illness returning.”

— Dr. David Jernigan, Founder

“Illness from infections is like having termites in the wood of your house. If you find and kill them right away, then life goes back normal. If you don’t find or effectively eliminate the termites until years after they have been there, then just killing them does not repair the damage they did to the wood of your house and the next storm can easily knock down. Even when Induced Native Phage Therapy is amazingly successful at eliminating the infections, the damage remains in your tissues and systems of your body, therefore your symptoms may be better, but total health will require treatments and therapies to repair all of the damage.”

— Dr. David Jernigan, Founder

“In long-term infections and chronic illness, it is a myth that your doctor is telling you that you will get out of the proverbial wheelchair when they can kill all of the infections. The damage must also be effectively and quickly addressed.”

— Dr. David Jernigan, Founder
“Not many doctors are trying to figure out your unique situation, beyond a diagnosis. Once they are convinced of the diagnosis, they simply run the standard treatment protocol. Our doctors are working to determine why you got sick in the first place, and identify and facilitate the correction of your unique body issues.”
— Dr. David Jernigan, Founder
“We will never sacrifice or knowingly injure one part of your body in order to fix another!”
— Dr. David Jernigan, Founder

“We definitely do not believe you must feel worse before you feel better! When the doctor knows what the underlying problems are and works with the natural design and function of the body, the symptoms almost always start improving.”

— Dr. David Jernigan, Founder
