Founder & Formulator
The Founder
A physician's formula, not a marketing one.
Replenish Beverages was founded by Dr. Reza Tirgari, M.D., a physician and biochemist with training in molecular biology, neuroscience, and molecular oncology. He earned his medical degree from the University of Maryland and conducted research in molecular oncology and cellular physiology at Georgetown University’s Lombardi Cancer Institute.
Dr. Tirgari’s work in emergency medicine, trauma care, and international medicine with Doctors Without Borders focused on treating fluid loss through Oral Rehydration Therapy. He applied the sodium-glucose cotransport mechanism—the process in the small intestine that actively absorbs water and electrolytes more efficiently than water alone—to create science-backed recovery drinks.
Replenish Beverages uses this physiological principle and precise biochemical ratios to support cellular hydration and recovery after physical exertion, travel, or demanding social occasions.

Credentials
The background behind the bottle
Recovery drinks are easy to make and easy to fake. This one was formulated by a doctor with the training to know what actually helps the body bounce back.
Doctor of Medicine
M.D. from the University of Maryland, with a focus on neuroscience and neurochemistry.
Biochemistry
An undergraduate degree in biochemistry. He understands the formula at the molecular level.
ER & Trauma Medicine
Years on the front line of emergency and trauma care, where recovery is not optional.
Research Pedigree
Studied molecular oncology and physiology at Georgetown's Lombardi Cancer Institute.
The Origin
It started with patients in the field, not a focus group.
Working with Doctors Without Borders, Dr. Tirgari developed an oral rehydration formula to help patients in developing countries recover without the need for IV treatment. It had to work fast, it had to be simple, and it had to be safe.
That same principle became Dr. Replenish: real recovery science, made drinkable, for the night out, the hard workout, and the cold coming on.

The Philosophy
Three ways the body recovers
01
Rehydrate
Electrolytes and key nutrients replace what a long night, a hard workout, or a fever drains.
02
Calm inflammation
Time-tested botanicals like turmeric and ginger bring anti-inflammatory support.
03
Support recovery
Targeted agents help the body process, repair, and get back to itself, faster.
The AfterX Recovery Series
Recovery, formulated by a doctor.
One for the night out, one for the workout, one for the cold coming on. Try the trio and keep yourself covered.
