For the best product stability, we recommend FedEx Overnight with ice packs and a cooler. It’s a $29.99 flat rate in the continental US, which is already $10–$15 off our actual cost.

We do offer free ground shipping (without ice packs or cooler), but it’s only a good idea when the weather’s cold. Orders ship from Cleveland, Ohio, usually Monday–Wednesday, to avoid weekend delays.

No PO boxes for overnight shipping, please. And remember: Refrigerated items can’t be returned or refunded.

Looking for a comprehensive probiotic that supports digestion and is hypoallergenic? Look no further than Kirkman's Pro-Bio Gold™. Our proprietary formulation contains 20 billion colony-forming units of friendly bacteria, providing "total coverage" of the small and large intestinal tracts.

Pro-Bio Gold™ features a combination of the most important "resident" and "transient" microorganisms, working synergistically to support gastrointestinal and genitourinary health. Our probiotic strains have undergone DNA fingerprinting to ensure their identity and long-term stability. In fact, more than 65 scientific studies and published articles have been written in support of the strains, demonstrating their ability to survive stomach acid and bile salts, support the immune system, alleviate occasional diarrhea and constipation, and possibly create an inhibitory effect on free radical activity in the colon.

In addition to its many health benefits, Pro-Bio Gold™ is free of soy, wheat, casein, gluten, milk, corn, egg, yeast, gelatin, artificial flavorings, artificial colorings, peanuts, tree nuts, and fish. Each bottle contains 120 vegetarian capsules that have been purity tested for your peace of mind.
