Colloidal Gold: Lab Testing & Our Commitment to Safety
Lab testing results
Our colloidal gold has been independently tested at the School of Chemical Sciences, University of Auckland, by Dr Geoff Waterhouse. Here is a summary of the data collected.
Microscopy analysis
Indicates that the majority of the gold colloids are of size less than 10 nm (< 10 nm). Overall, the colloid solution appears very stable and the colloids free from aggregation. Transmission Electron Microscopy (TEM) analysis was used to evaluate the size and shape of the gold colloids. The size of the gold colloids can be determined by comparison with the scale bar on each image. Most colloids have a diameter of < 10 nm (~ 5 nm); very few particles show to be slightly larger (~ 15 to 20 nm in size). The gold colloids are of spherical or elliptical shape.

Absorbance spectroscopy
The gold colloid solution showed an absorption band at 522 nm, which is typical for gold colloids of size less than 20 nm. This absorption band is the green part of the visible spectrum, and hence the gold solution appears red when viewed under white light (i.e. we see the other wavelengths of the visible light not absorbed by the gold colloid solution).
Is colloidal gold safe?
Yes. Gold is inert inside the human body, and colloidal gold is non-toxic and non-addictive, with a long history of use in Chinese and Ayurvedic medicine. There are no known adverse effects or interactions with medications when used as directed.
The distinction that matters is gold salts (gold chloride, chlorauric acid): a different substance entirely, which can be toxic in high amounts. Our true colloidal gold contains no gold salts at all, only pure elemental gold and ultra-purified, energised water, so it stays pure, stable and highly absorbable.
