Main Highlights
  • 𝐒𝐀𝐂𝐂𝐇𝐀𝐑𝐎𝐌𝐘𝐂𝐄𝐒 𝐁𝐎𝐔𝐋𝐀𝐑𝐃𝐈𝐈 𝐏𝐑𝐎𝐁𝐈𝐎𝐓𝐈𝐂: Saccharomyces is a patented & clinically studied strain that has been used for its regulatory effect on the intestinal flora, helping to maintain normal balance in the intestine.
  • 𝐍𝐎 𝐅𝐈𝐋𝐋𝐄𝐑𝐒: We strive for optimal health. That's why our Saccharomyces Boulardii probiotics do not contain fillers, excipients, flow agents, or the additive magnesium stearate, which is believed to inhibit nutrient absorption. We don't use questionable ingredients and do our due diligence to find authentic versions/forms of nutrients. Our probiotic capsules are non-GMO and gluten-free.

We use a proprietary process of less-aggressive drying at a controlled temperature and lower vacuum to preserve complete probiotic yeast cells, delaying the Saccharomyces aging process.
  • 𝐂𝐀𝐍 𝐁𝐄 𝐔𝐒𝐄𝐃 𝐃𝐀𝐈𝐋𝐘:Pure TheraPro Rx Saccharomyces probiotic capsules deliver a minimum of 10 billion colony-forming units per daily serving (250mg per capsule). These probiotics supplement capsules quickly achieve high concentrations in the GI tract, then clear within 3-5 days after discontinuing use. Take 1 to 2 capsules daily in the morning or as directed by a healthcare provider.
  • 𝐀𝐁𝐎𝐔𝐓 𝐔𝐒: Pure TheraPro Rx was founded in Denver Colorado to formulate and manufacture the highest quality supplements available on the market today. Purity is our priority, which is why we insist on using patented, clinically studied ingredients, and never utilizing fillers, flow agents, excipients, or ingredients sourced from China. We also never use dairy, gluten, corn, soy, or other common allergens in any of our class-leading, practitioner-recommended formulas.
