Dr. Reza Tirgari - Founder
Dr. Tirgari began his medical journey with research in molecular biology and earned a Biochemistry degree before completing his M.D. at the University of Maryland, focusing on neuroscience and neurochemistry. He further honed his expertise during a research year at Georgetown University’s Lombard Cancer Institute, studying molecular oncology and physiology.
His medical career in emergency care and trauma inspired a passion for healing, leading to the creation of TirgariMD, a skincare line designed for specific skin conditions. Through his work with Doctors Without Borders, Dr. Tirgari developed an oral rehydration formula to help children in developing countries, avoiding the need for IV treatments. This innovation also led him to explore recovery solutions for those needing faster detox and wellness support.
Combining years of research, biochemistry expertise, and real-world testing, Dr. Tirgari founded Replenish Beverages—a company dedicated to health, healing, and recovery.
