About Physician's Choice
Physician's Choice is a Colorado-based supplement brand founded by entrepreneur Logan Chierotti, built around a gut-health-first product line that includes probiotics, digestive enzymes, and fiber formulas alongside a smaller catalog of herbal supplements. The company positions its formulas as developed with doctors, backed by a Scientific Advisory Board of MDs, naturopathic doctors, and functional-medicine practitioners spanning pediatric gastroenterology, OB/GYN integrative medicine, and naturopathic care. By late 2023, trade press reported the company was on pace for roughly $150 million in annual sales, driven largely by its flagship probiotic line.
The brand's 60 Billion Probiotic is marketed as the #1 selling probiotic on Amazon, and the listing we track backs that claim with over 144,000 verified Amazon reviews at a 4.6-star average — among the largest review bases of any probiotic supplement we evaluated. The formula's 10-strain, delayed-release capsule and Non-GMO Project Verified, third-party-tested manufacturing reflect the clinical-formulation approach the company built its reputation on before later expanding into ashwagandha and other single-ingredient herbal supplements.
