TJ Nutrition

TJ Nutrition is a private U.S. nutraceutical company that develops and sells patented dietary supplements focused on vagus nerve and autonomic nervous system support. The company was founded by optometrist and researcher Dr. Diana Driscoll and commercializes products including Parasym Plus and Parasym Plus Eyes through its Vagus Nerve Support brand. Its products are positioned for consumer wellness and symptom support in areas such as digestion, calmness, tear production, cognition, and inflammation, rather than as prescription therapeutics. TJ Nutrition appears to operate as a commercial supplement business with practitioner wholesale channels, scientific marketing around patented formulations, and an advisory board with clinicians and researchers. It is healthcare-adjacent and health-focused, but it is not a biotech or pharmaceutical drug developer with a conventional clinical pipeline.
