Florajen® Probiotics were founded by bacteriologists over 25 years ago with the intent of creating effective, affordable options to help people avoid the unpleasant side effects of antibiotics. Florajen is known for having the right strains at the right cell count and maintaining a Cold Chain Commitment™, keeping our probiotics refrigerated, fresh and potent from manufacture to delivery. Available at the pharmacy counter, all of our 30 counts retail for under $20.
