Colloidal Silver: Lab Testing & Our Commitment to Safety
Lab Testing Results
All of our Colloidal Silver and Colloidal Gold products have undergone independent third-party lab testing in collaboration with NZ LABS and the University of Auckland to verify their safety, purity, and effectiveness.
Note: All cultures were maintained in accordance with the recommendations of the Curator of the Culture Collections Centre NZ, Communicable Disease Centre of New Zealand and Laboratory Services quality control systems.
Colloidal Silver: Microbiological Challenge Tests
Test Organism Number: 09N25814

1 minute -4 minutes -8 minutes -12 minutes.
The following organisms were used in the test:
Staphylococcus aureus (ATCC – 6538)
Escherichia coli (ATCC – 8739)
Candida albicans (ATCC – 10231)
ATCC Recovery Level (cfu!l nl)
Test Outcome:
On all tested Organisms listed above, there was a full kill rate within 4 minutes with no signs of re-growth within 12 minutes with Bio-Colloidal Silver from Origin Health Ltd.
Particle size of our Silver
1. This is a transmission electron microscope photo of CS poorly made samples of home made colloidal silver, (this would cause Argyria) photos were made at 100,000 power magnification.
2. This is a transmission electron microscope photo of our CS. The typical particle size is in the range of .001 to .005 um (Micrometer) that converts to 1 – 5 Nanometer in size. Magnification is 100,000 times. Notice the uniformity of particle shapes. Also note the particles are separate rather than agglomerated. There are basically 2 different sizes. shown. This is very high quality ionic colloidal silver.

Is Colloidal Silver Safe?
Yes, Colloidal Silver is safe when properly manufactured and used as directed. However, misinformation has caused confusion, often linking true colloidal silver with other silver compounds like silver salts, nitrates, and chlorides, which are not the same and have been associated with side effects like argyria (a rare skin discoloration condition).
Key Facts About Colloidal Silver Safety:
- Properly made Colloidal Silver does not cause argyria.
- No reported cases of adverse health effects from high-quality Colloidal Silver.
- Media cases of argyria were caused by silver salts, high-concentration homemade solutions and their excessive prolonged use.
- Colloidal Silver is non-toxic when used as directed.
A 1999 FDA request found no cases of deaths, allergic reactions, or negative interactions related to properly made Colloidal Silver.
Understanding Argyria and Colloidal Silver
Argyria is a purely cosmetic condition that occurs when large amounts of silver compounds accumulate in the skin, leading to a bluish-gray discoloration when exposed to sunlight.
However, properly manufactured Colloidal Silver does not cause argyria because:
- It consists of pure nano-sized silver particles, not silver salts or proteins.
- It does not accumulate in the skin like silver nitrates or silver chloride solutions.
- All known cases of argyria involved excessive use of impure silver compounds, not true Colloidal Silver.
Misinformation in the Media
Some widely publicised cases of argyria, such as Paul Karason (the "Blue Man"), resulted from years of drinking highly concentrated, self-made silver solutions mixed with salts—not properly manufactured Colloidal Silver.
Similarly, Stan Jones and Rosemary Jacobs both consumed silver compounds in excessive amounts, far beyond any reasonable or recommended use.
Common Sense Guidelines for Safe Use
Like any supplement, Colloidal Silver should be used responsibly. While it is safe for daily support, taking extremely high doses for extended periods is unnecessary and not recommended.
