Collection: Colloidal Silver

Every bottle of Origin Health colloidal silver starts in our Auckland facility: 99.999% pure ionic silver at 10ppm in energised, ultra-pure water, and nothing else. No additives, no preservatives. We test the strength of every batch in-house, and our products have been independently lab-tested through NZ Labs and the University of Auckland.

The range covers liquid in glass bottles from 250ml up to food-grade bulk sizes, plus a spray, nasal spray, gel, cream and drops. That means there's a format for everyday immune support at home and one for the travel bag. Our water is treated with Grander Living Water technology and we bottle in glass to preserve quality. You can check the lab testing results or read our guide to colloidal silver if you're new to it.

Orders ship tracked from Auckland, with free urban shipping NZ-wide over $40. We also make colloidal gold.

Which colloidal silver format should you choose?

Liquid is the everyday staple for immune support, available in glass bottles from 250ml or food-grade bulk sizes up to 21 litres if the whole household is on it. The spray covers skin, mouth and throat when you're out and about, and the nasal spray earns its spot in the travel bag through the ills and chills season. Gel and cream give topical support for dry or irritated skin, minor cuts and grazes, while drops offer precise dosing from a compact 50ml glass bottle.

How our colloidal silver is made

Our silver is produced in Auckland with a low-voltage electrolysis process that keeps particle size consistently small, in the 1 to 5 nanometre range confirmed by electron microscope analysis. We test the strength of every batch in-house, and our products have been independently lab-tested through NZ Labs and the University of Auckland.
