How are we different?

Our premium quality colloidal zinc is manufactured in the Netherlands by Crystal Colloidals. It is classified as "true colloidal zinc" with a colloidal content of 100%. Our manufacturer is one of the few worldwide to have achieved a colloidal content of 100%.

With a particle size of 20 nanometres, our product achieves the technically smallest particle size possible. With a surface area of 0.6 m²/l, our colloidal zinc has the maximum possible surface area. Due to its small particle size, the large number of particles in the solution, and the significant surface area, it exhibits maximum effectiveness even at the low zinc concentration of 15ppm. This means that despite its high effectiveness, only a low zinc content needs to be applied, ensuring no burden on the body.

Our product contains exclusively ultra-pure zinc and distilled water. The water is deionised and revitalised using the Grander method. Unlike zinc water with an ion content, our product can be stored near electrical devices due to its stability.

Water has a significant impact on the production of colloidal zinc. Our colloid is dissolved in distilled, deionised, and revitalised water. We utilise light-protected and environmentally friendly amber glass packaging.

Colloidal zinc is a liquid dispersion consisting of water and zinc nanoparticles. The zinc is finely dispersed in distilled water.

In colloidal zinc, the concentration is measured in ppm, which stands for parts per million. This term actually refers to the ratio of the active ingredient (zinc) to one million parts of the solvent, suspension, or dispersion medium (water).

In the case of colloidal zinc, this measurement represents the weight ratio between the zinc and the water in mg/kg. Since 1 litre of water weighs 1kg, a concentration of 15ppm means that 15 milligrams of zinc are suspended in 1 litre of water.
