Dr. J.P. Johnston is a retired family physician with 30 years of experience in clinical medicine and the founder of Verity Health Institute, an educational initiative devoted to examining the medical evidence for nutritional therapies, supplements, and repurposed medications in cancer care. Throughout his career, Dr. Johnston has maintained a particular interest in translating complex medical research into information patients and families can understand and discuss with their healthcare providers. He is also the author of 17 books, five of those as a ghostwriter for CEOs, bringing decades of experience in research, writing, and communicating complicated subjects to a broad audience.
Beyond medicine and publishing, Dr. Johnston has worked extensively in film and media. He wrote and produced the feature film The Reliant, released in 2019, and has served in executive roles in film production and media companies. Today, he brings those worlds together at Verity Health Institute, using medical research, writing, filmmaking, and digital media to make scientific evidence more accessible to the public. Dr. Johnston is the father of ten children and resides in Charlotte, North Carolina.
Promising medical research does not always translate quickly into clinical practice—particularly when it involves inexpensive supplements, existing medications used for new purposes, or therapies that lack FDA approval for a particular disease.
Dr. Johnston leads Verity Health Institute’s effort to bridge that gap by bringing published medical research on cancer and other diseases directly to the public. VHI examines the evidence, explains what the research actually found, and gives people the information they need to have better-informed conversations with their healthcare providers.
Other healthcare professionals also contribute their experience and expertise to VHI’s educational mission.
Every review, written or on video, is held to the same standard regardless of whether it covers a supplement or a pharmaceutical. We separate what has been shown in laboratory and animal research from what has been shown in human clinical trials, and we say plainly when the evidence for a claim is thin or absent rather than rounding up to sound more definitive.
Nothing published by the Institute is a substitute for a conversation with a treating oncologist. Where a review touches on a product available for purchase, that connection is disclosed plainly within the piece.
