Colloidal silver is a liquid suspension of silver particles, often marketed for its purported antimicrobial and health benefits. It is created by suspending silver particles in water, typically through an electrolysis process. The particles in colloidal silver vary in size, ranging from nano-sized to much larger, and their distribution is often inconsistent. It has been used in alternative health remedies and as a natural disinfectant, though its medical effectiveness is not universally recognized, and excessive use can lead to health risks like argyria, a condition causing permanent skin discoloration.
How Does Colloidal Silver Differ from Nano Silver?
The main difference between colloidal silver and nano silver lies in particle size, precision, and application. Nano silver consists of carefully engineered particles within the 1–100 nanometer range, ensuring uniformity and enhanced antimicrobial properties. Its production often involves stabilizing agents, making it ideal for scientific and industrial use.
Colloidal silver, on the other hand, includes a broader range of particle sizes with less uniformity. It prioritizes purity, typically made using high-purity electrodes and pure water, which ensures safety for internal use.
