To ensure you’re getting the best colloidal silver, it should include the 3 S’s: safety, strength and stability.

Safety & Absorption

SILVER PARTICLE SIZE: According to the Encyclopedia of Chemical Technology, true colloidal silver contains particles between 1–100 nanometers. Natural Path / Silver Wings consistently produces exceptionally small silver particles, typically within the 1–10 nanometer range, reflecting the precision and quality of our manufacturing process.

The smaller, the better!

VERIFIED BY ADVANCED INSTRUMENTATION: Independent laboratories use highly sensitive instruments, including the Beckman Coulter Delsa Max and the Delsa Nano Photon Correlation Spectroscope to measure particle size and zeta potential. These instruments can detect particles as small as 0.6 nanometers, providing highly reliable particle size analysis.

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.

CONSISTENT 3rd PARTY RESULTS: Multiple production runs have shown particle sizes under 3 nanometers. All particle size testing is conducted by FDA registered, third party laboratories. Independent verification reports are available upon request.

Does PARTS PER MILLION (PPM) AFFECT PARTICLE SIZE? No. Particle size refers to how small each silver particle is, while PPM indicates how many silver particles are present in the formula. These are two separate measurements.

Small silver particle size for safety and nice absorption- check!

Strength

UNDERSTANING PPM: Parts per million (PPM) expresses the concentration of silver particles suspended in the liquid. Higher PPM formulas contain a greater number of silver particles in each serving.

Silver Wings offers a range of concentrations, including:
• 50 ppm
• 150 ppm
• 250 ppm
• 500 ppm

This allows customers to select the level that best suits their preferences.

COLOR AND QUALITY: Authentic colloidal silver naturally displays a translucent amber color. As the PPM increases, the amber tone becomes richer, reflecting the higher quantity of silver particles in the solution. This visual characteristic is one marker of true colloidal silver quality. Each batch is tested to verify that PPM levels fall within 5 percent of the labeled strength, meeting FDA and GMP compliance standards.

ECONOMY OF HIGHER CONCENTRATIONS: Higher PPM formulas provide the convenience of fewer servings per bottle compared to lower concentration products. For example, Silver Wings 50 ppm contains five times more silver particles than many 10 ppm products, while 250 ppm and 500 ppm offer even higher concentrations.

Stability

ZETA POTENITAL EXPLAINED: Zeta potential measures the electrical potential between particles in suspension, and is used to evaluate product stability. Values can range from 0 to 61 and above. A higher value indicates strong repulsive forces between particles, supporting long term stability in solution.

PROVEN STABILITY: Independent laboratory tests show that Silver Wings colloidal silver consistently demonstrates high zeta potential, with representative results in the mid 60s. This confirms a stable suspension with well dispersed particles.

WHY STABILITY MATTERS: Low zeta potential can lead to particle clumping or the formation of larger masses, which is undesirable in colloidal preparations. Independent lab findings note that low zeta potential is associated with agglomeration. Silver Wings stability testing is performed using instruments such as the Delsa Nano C and Zeta Potential Analyzer to ensure high quality product performance.
