Blazing the Path for Advancement in Alternative and Regenerative Medicine

Dr. John Lieurance, ND, DC, a renowned Naturopathic Physician and Chiropractic Neurologist with 28 years of experience in natural health and wellness, has garnered significant attention for his groundbreaking work with methylene blue, high-dose melatonin, regenerative medicine in stem cell therapy, inner ear regeneration, and neurological care using Endo-Nasal Cranial Adjustments known as Functional Cranial Releases (FCR).


With nearly 30 years in practice. Dr. Lieurance has developed some of the most potent healing protocols and systems, integrating tools like X-Cells guided by ultrasound and SunaVea for inner ear regeneration. He serves as the Scientific Advisor and Chief Formulator for MitoZen Scientific, masterfully blending therapies that address the three pivotal pillars: Vitality, Identity, and Divinity, promoting physical, mental, emotional, and spiritual health and wellbeing.

Dr. Lieurance's innovative FCR technique, which combines functional neurology testing, eye function assessments, and specific endo-nasal balloon manipulations, has been hailed as a game-changer by many, including prominent figures like Dana White, CEO of UFC. White, who has struggled with nose problems for most of his life, shares,


"I have had nose problems most of my life. Since doing Endo-Nasal Balloons with Dr. John, it has been life-changing for me. I can breathe so much better, and it has stopped me from snoring. I would highly recommend it to EVERYONE!"

Dr. Lieurance has also worked with top surfers, including those featured in HBO's "100 Ft Wave," such as CJ Macias and Garrett McNamara. McNamara shares,


"I could not breathe through my right nostril for many years after a massive wipeout at Mavericks. Dr. John has opened this up with his technique, and my brain even works better, and my surfing has improved."
