Allan Sutton's Colloidal Silver is the Original All-purpose product well known for its quality manufacturing and purity in content. It contains 16-20ppm of silver.

Only the purest method of manufacturing is used which is the electrolysis process. This is where silver electrodes are immersed in distilled or de-ionised water and a current is passed between the electrodes through this medium.

Some Colloidal Silver manufacturers add salts to improve the conductivity to speed up the process. However, the silver ions may bond with the dissolved salts forming potentially toxic compounds. It is also a common occurrence for some operators to add tea, food colouring or other substances to achieve a golden colour. If Colloidal Silver is made with a minute particle size, then it should be colourless.
