Colloidal Gold: Lab Testing & Our Commitment to Safety

Colloidal Gold: Lab Report Summary of 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) TEM analysis was used to evaluate the size and shape of the gold colloids. A selection of TEM images taken at different magnification is shown below. 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, Colloidal Gold is widely recognised as safe, with a long history of use in traditional wellness practices. Unlike certain gold compounds used in medical treatments, pure Colloidal Gold contains no additives or toxic chemicals.

Key Facts About Colloidal Gold Safety:

  • Non-toxic and non-addictive, suitable for long-term use.
  • No known adverse effects or interactions when used correctly.
  • Used traditionally in Chinese and Ayurvedic medicine for centuries.

Unlike gold salts or gold chloride, which can be toxic in high amounts, our true colloidal gold is pure, stable, and highly bioavailable, ensuring safe and effective use.
