Go for it if you...
You want the simplest possible ingredient list: this stick contains exactly one published ingredient, with no fragrance, baking soda, or fillers
You or your teen have reacted to baking soda or fragranced deodorants and need a gentle, unscented option
You are on a budget: at $7 per ounce one stone costs a fraction of most natural sticks and can last months
You understand potassium alum is an aluminum salt and are comfortable with how it differs from antiperspirant aluminum
You want odor control without blocking sweat, for example for a kid starting their first deodorant
You have sensitive skin or a history of deodorant rash and want a stick with no baking soda and no fragrance
You want a deodorant an independent lab has screened for forever chemicals with none detected
Your kids or teens are starting deodorant and you want every ingredient published, with none of the legacy problem ingredients
You want a widely available natural stick at about fourteen dollars instead of a boutique price
The main thing to know
The 'mineral salts' on this label are potassium alum, and potassium alum is an aluminum compound. It works differently from the aluminum actives in antiperspirants: it sits on the skin's surface to stop odor bacteria rather than plugging sweat glands. But if you are avoiding aluminum in every form, or anyone in your family has an aluminum contact allergy, this is not an aluminum-free product.
Native reformulated this stick in January 2026 and removed the baking soda. Retail listings and sticks already on shelves may still be the old formula, so check the label: if you see Sodium Bicarbonate, that is the old version. The 72 hour odor claim also has no published study behind it.
Skip this if you...
You are avoiding aluminum in every form: potassium alum, the only ingredient here, is an aluminum compound
Anyone using it has an aluminum contact allergy, since the salt sits directly on the skin
You only buy products audited by an outside certifier such as EWG Verified or MADE SAFE; this one has none
You need an antiperspirant: this stone controls odor but does nothing to reduce sweating
You only buy products carrying an independent certification mark like EWG Verified or MADE SAFE; this stick has none
You need verified multi day odor protection backed by a published study; the 72 hour claim has no public evidence behind it
You are cutting plastic from your bathroom; this tube is virgin plastic, though Native sells a separate paperboard version
Your skin reacts even to magnesium based odor fighters like the magnesium oxide in this formula
Neither of these quite what you're looking for?
