I dont know if this is deoderderant related, but figured I'd start here and get some feedback.

I recently saw these purple pit stains on a white tee, and yellow stains on a linen shirt (3rd photo). I haven't had yellow staining issue since switching to aluminum free deoderderant (about a decade ago) and I've never had purple stain issues before.

I've used native deodorant for a few years. About 2 weeks ago I switched from eucalyptus and mint to coconut and vanilla (Ive used both scents before with no issues).

Routine: shower at night and spray pits with glycolic acid. In the morning I use deodorant.

Supplements: recently (past 3 weeks) added vitamin B and berberine
