Master Supplements uses scientific research to develop powerful probiotic formulations and bioactive prebiotics. The main goal is to provide those in need with the highest quality products that support healthy living and provide digestive results you can feel working!
In 2003, Randolph S. Porubcan created the formula for Theralac®, Master Supplements’ first probiotic. Porubcan, 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 scientifically researched strains. Theralac® offers a unique delivery through harsh stomach acid as well as the special prebiotic stimulation with LactoStim®.
