Higher Nature Colloidal Silver is composed of 80–90% particulate silver and 10–20% ionic silver. This product simply contains two ingredients: premium-grade silver and purified water. Particle sizes in the silver range from 0.6 to 5 nanometres. The silver particles' small size is significant because they offer a higher surface area per volume, increasing the silver's ability to have an impact. Colloidal silver is anti-bacterial, anti-viral and anti-fungal. It is a good way to boost the immune system and treat infections. It can be sprayed as needed into the back of the throat, and onto the skin, ears or nostrils. It can also be used on any surfaces as a disinfectant. This product is perfect for using at home, on the go, or in public. Ideal for taking care of numerous pets as well as family and friends.
