Safety (and Absorption)

SILVER PARTICLE SIZE: According to the Encyclopedia of Chemical Technology, a silver colloid particle size must range between 1-100 nanometers. Silver Wings silver colloids always range between 1-100 nanometers.


PARTS PER MILLION (PPM) is the number (not size) of silver particles per serving. The greater the number of silver particles per serving yields greater concentration. Silver Wings conveniently offers a variety of PPMs (50PPM, 150PPM, 250PPM and 500PPM).


ZETA POTENTIAL analyzes the stability of silver particles in suspension. This ranges between 0-61+. Silver Wings has high zeta potential (i.e. Lot 9302 Zeta Potential 66), which proves the stability of our colloidal silver.

Safety: Silver Particle Analysis

Provides measurements of submicron particle size and zeta potential. It has the ability to measure silver particles as small as 0.6 nm, and is unparalleled. Nano Correlation Spectroscope is the most accurate method of testing the overall silver particle size. This analysis enables one to view the size of all silver particles.

These analyses were conducted by FDA registered 3rd party laboratories. Natural Path / Silver Wings solely utilizes qualified 3rd party independent laboratories for silver particle size analysis. Upon request, 3rd party results can be provided. Silver Wings always ranges in a true colloid size between 1-100 nanometers.

Q: Does parts per million have anything to do with silver particle size?
A: NO. PPM is the number of silver particles, thus the strength of concentration.

Strength: Parts Per Million

Parts Per Million (PPM) is the number of silver particles per serving.

Every bottle’s PPM is verified within 5% (+/-) as labeled on each bottle in compliance with FDA and GMP standards.

Q: Does parts per million have any correlation with color?
A: YES. Silver has a translucent amber color.

  • The higher the PPM= The darker the amber color
  • 1 teaspoon of Silver Wings 250PPM= 25 teaspoons of 10PPM
  • Higher PPM strength offers the convenience of less dosages per day

Stability: Zeta Potential

HIGH ZETA POTENTIAL = silver particles are stabilized in suspension.

LOW ZETA POTENTIAL = silver particles tend to coagulate or flocculate i.e. form clumps or masses of larger silver particles. EBATCO Laboratory states, “Particles with lower Zeta Potential have a tendency to collide and form large agglomerations.”

Silver Wings Zeta Potential is analyzed by 3rd party independent laboratories with DelsaNano C and Zeta Potential Analyzer instruments.
