True Amber Colloidal Silver – Pure & Natural UK Colloidal Silver has a worldwide reputation for providing the best quality True Amber Colloidal Silver. Using only steam distilled water and elemental silver, we have been producing this pure and natural product for nearly 20 years. Based in South West England, we have access to naturally soft water that is so pure, only a single distillation is needed to make it perfect for production, which means our solutions naturally have a lower carbon footprint. We use pharmaceutical grade light proof glass bottles & because of this attention to quality, the reputation of our True Amber Colloidal Silver has spread across Europe, with USA & Australia being one of our growing markets.
