Based in Science

In 2003, Randolph S. Porubcan created the formula for Theralac®, Master Supplements’ first probiotic. It led the way in so many vital areas that have become cornerstones to many quality probiotics available today. Randy, a microbiologist, relied on over 40 years of experience researching naturally occurring, symbiotic microorganisms to develop a probiotic formula that would colonize the entire GI tract with well documented strains. He authored seven U.S. Patents that protected the unique delivery through harsh stomach acid as well as the special prebiotic stimulation with LactoStim®.

As a scientist, Randy knew that he would need help spreading the word on this breakthrough probiotic so he partnered with Jeff Thurston, a seasoned sales and marketing executive, who promptly took the torch and began attending countless healthcare professional events and trade shows. These professionals became Master Supplements' foundation and they were clearly excited about the positive results. Word of mouth became our greatest advertising and soon Theralac was reaching retailers, professionals, and consumers around the world. In the years that followed, a full line of digestive health products were developed that matched Theralac’s high standards and proven efficacy.
