Safety (and Absorption)

SILVER PARTICLE SIZE: According to the Encyclopedia of Chemical Technology, a silver colloid particle size must range between 1-100 nanometers. The smaller, the better. Silver Wings silver colloids always range between as little as 1-10 nanometers which sets the benchmark.


Beckman Coulter Delsa Max and Delsa Nano Photon Correlation Spectroscope

These instruments provide measurements of submicron particle size and zeta potential. They have the amazing ability to view and measure silver particles as small as 0.6 nanometers. That’s micro small! The Nano Photon Correlation Spectroscope is the most accurate method of testing and analysis of the overall silver particle size.


Different production runs, same results– all silver particles under 3 nanometers:


These particle size analyses were conducted by FDA-registered 3rd-party laboratories. Upon request, these independent lab results may be provided.


Does PARTS PER MILLION (PPM) have anything to do with silver particle SIZE? 

NO. PPM is the total number of silver particles (strength of concentration).


PARTS PER MILLION (PPM) is the number of silver particles per serving (not size). The greater the number of silver particles per serving yields greater concentration.

Higher PPM = stronger immune support.

Silver Wings conveniently offers a variety of PPM strengths: (50PPM, 150PPM, 250PPM and 500PPM).

Every bottle’s PPM is verified within 5% (+/-) of what’s on the label. This is within FDA and GMP compliance standards.

Does PPM have any correlation with the liquid color?

YES. Silver actually has a translucent amber color.  The higher the PPM, the darker the amber color.


Silver Wings’ higher PPM strengths offer the convenience of less dosages. Silver Wings’ 50ppm is 5x stronger than other 10ppm brands. Our 250 and 500ppm formulas are 25-50x stronger so for about the same price Silver Wings is MUCH MORE ECONOMICAL!


ZETA POTENTIAL analyzes the stability of silver particles in suspension. This ranges between 0 – 61+. The higher, the better!

Silver Wings has high zeta potential. See the below 66 score which proves the stability of our colloidal silver.


Silver particles that have a LOW zeta potential tend to coagulate or flocculate (form clumps or masses of larger silver particles. Not good! EBATCO Laboratory states, “Particles with lower zeta potential have a tendency to collide and form large agglomerations.”

Silver Wings zeta potential is analyzed by independent laboratories using Delsa Nano C and Zeta Potential Analyzer instruments.
