How products are chosen

The probiotic test

A deodorant is listed only when the maker's published ingredient list names a probiotic or postbiotic ferment (for example lactobacillus ferment or bifidobacterium ferment). Front-label or product-page claims about "probiotics" without a matching named ingredient do not count. The product page shows the full list so you can check.

Sources

Each page uses the maker's product page plus at least one further source we actually opened, and shows the date checked. We leave out products we cannot confirm are currently sold.

No invented rankings

We do not publish scores that have not been earned. Products our editor has tested hands-on get an Editor's Choice call-out and are listed as the Best; no product carries that label until it has been tested. We do not accept payment for placement, and the facts on each product page come from the maker's own page and at least one other source.
