Physician's Choice was founded in 2017 by Logan Chierotti and Ryan Russo in Wheat Ridge, Colorado, and has grown into one of Amazon's best-selling probiotics. That's a real, fast-growing DTC brand — not an anonymous seller — but it's worth being accurate that this is a modern startup, not a legacy pharmaceutical manufacturer like some other products on this list.
Probiotic supplements contain live microorganisms, and general medical guidance flags a documented infection risk for immunocompromised individuals — chemotherapy patients, organ transplant recipients, and people with central-line catheters, among others — who are generally advised to consult a doctor before taking any probiotic, not just this one.
Each capsule provides 60 billion CFU across 10 Lactobacillus and Bifidobacterium probiotic strains, plus a 150 mg organic prebiotic blend. The individual strain names aren't consistently published on the current product page — a real label-transparency gap worth knowing about rather than assuming full strain-level disclosure. The capsule itself is acid-resistant and delayed-release, meaning it's designed to survive stomach acid intact and release its contents further along in the intestines, where probiotic organisms are actually useful, rather than breaking down before they get there.
CFU stands for colony-forming units — a count of live, viable microorganisms in a serving at the time of manufacture. It's the standard way probiotic potency is measured on a label, though actual live counts can decline somewhat over a product's shelf life depending on storage.
It depends on the specific product and strains used — some probiotics are shelf-stable at room temperature, others recommend refrigeration to preserve potency. Check the storage instructions on your specific bottle rather than assuming one rule applies across brands.
