A Silver Hydrosol may be your most effective tool for maintaining and sustaining your immune defenses in the presence of emerging strains of bacterial, viral and fungal infections, and for tissue regeneration support. Note: Make sure you look for a 23 ppm formulation which consists of ultra-pure water and silver only and has the smallest particle size possible. As particle size decreases, energy increases, giving you MORE from less. There is an ideal balance between safety and effectiveness. Only a high quality, 23 ppm formulation can offer this. Argentyn 23 was developed specifically for healthcare professionals.
