So, you want to look for a formula with the maximum bioactivity and thus lower concentration. Be cautious about products which claim to have incredibly high concentrations, in the hundreds and even thousands of parts per million! When choosing a silver supplement for immune support, it should be tasteless, safe, pure and effective. Add Bio-Active Silver Hydrosol to your daily routine and start your journey towards health sovereignty today!
Close menu. Shop Products. Product Resources. Silver Keywords: colloidal silver, nanodispersion, bio-active, supplement, antimicrobial, UV-Vis analysis. Introduction The unique properties of silver have been known and exploited by humans since antiquity. Materials and Methods Material Fourteen of the most popular colloidal silver products purchased from Amazon www. Electron Microscopy UV-Vis spectrometry cannot determine if a given size silver entity is a single particle or an aggregate as both absorb at the same wavelength.
Commercial Samples Evaluated The products analyzed are listed in Table 1 in the increasing order of silver concentration claimed on the label. Best Nano Silver 30 5. Open in a separate window. Results Visual Evaluation The results of the visual examination are presented in the last three columns of Table 1.
Figure 1. Figure 2. Electron Microscopy Analysis The electron microscopy analysis was performed only for samples 12—14 since in samples 1- 10 no silver particles were detected and for Trace Silver Sample 11 it was not possible to obtain a representative sample for either FESM or STEM.
Figure 3. Figure 4. Figure 5. Figure 6. Conclusion The results of this evaluation show clearly that 10 of 14 products evaluated contain only ionic silver. References 1.

Silver nanoparticles: A new view on mechanistic aspects on antimicrobial activity. Soothes irritated or reddened skin. With regular use, it regenerates the skin and has beneficial effects. Colloidal silver at a concentration of 10 ppm holds transparent clear color. Exceptions are stronger concentrations above 40 ppm, which can agglomerate over time particle aggregation occurs , which results in a slight collision of colloid, but this is not a defect.
The concentration of the solution is given in ppm parts per million. Purchased Colloidal silver not recommended to dilute! In addition, the solution can be degraded by impurities which are common in ordinary but also in distilled water and can not be removed in domestic conditions in any way.
Colloidal silver is available in these variations of concentrations: 5, 10, 15, 20, 30, 40 and 50 ppm. Do not use internally! Do not use on damaged skin! In case of contact with eyes rinse with water. Keep out of the reach of children. Colloidal silver should not be used in case of hypersensitivity to metallic silver. Before first using colloidal silver, first try to pour a bit of colloidal silver on your wrist, and wait about an hour for a silver allergy.
Pregnant women and nursing mothers should consult their doctor about the use of colloidal silver. Store in the dark. Do not freeze! Toxicity: The maximum non-toxic silver dose for humans according to the WHO is 1 gram of silver per year ie 2. In 1 liter of 10 ppm silver colloidal silver is contained 10 milligrams of silver. The size of a reasonable daily dose is individual with respect to the current state of health, the use of other mineral preparations, eg colloidal minerals, individual tolerability and other factors.
The particle size is in the order of nanometers. It is available in these variations of concentrations: 5, 10, 15, 20, 30, 40 and 50 ppm. For nutritionally loaded and worn joints. Is it contaminated with other toxic heavy metals, or is silver the only detectable metal in it? You also want to be sure that pharmaceutical-grade purified water, meeting USP standards, is used in the manufacturing process.
To guarantee purity, look for silver manufactured in a GMP Certified facility and bottled in dark amber glass. Less is more with silver PPM. Technically, one PPM equates to 1 milligram per 1 liter of liquid. When a silver product contains the most active species of silver, coupled with the smallest particle size and greatest amount of positively charged silver, then a safe low concentration of 10 PPM bio-active silver is all that you will ever need.
