Amazon Basics Probiotic

Our verdict

Amazon Basics Probiotic works out to $0.14 per serving of probiotics 50b, at 5billion CFU per serving in capsule form. That puts it the cheapest quarter of the 43 probiotics 50b products we can price per dose, where the typical serving costs $0.29, a Value Index of 2.0 where the median product is 1.0. One container lasts 60 days at the label dose of 1 serving a day, about $4.35 a month. We could not verify a third-party certification for Amazon Basics in a public registry. Worked out from the current retail price as of 2026-11-13; confirm the live price on Amazon.com before buying.
