Theralogix

High-quality, research-based & NSF® certified nutritional supplements.

Theralogix was founded in 2002 by physician Dr. Mark Ratner with a clear goal: create supplements that healthcare professionals could trust and confidently recommend. The brand develops products backed by published scientific evidence, using carefully selected ingredient forms and dosages aligned with clinical research. What began with a single men's health supplement has grown into a portfolio of more than 30 spanning multiple specialties.

Plus, every product is independently certified by NSF® International for content accuracy and purity, with ongoing testing to ensure consistent quality.

Today, Theralogix is trusted by healthcare providers, researchers, and academic institutions alike for its science-first approach to nutrition.
