No. More is not always better. What makes one silver product more effective than another is not its PPM concentration, but rather its particle size, positive charge, form and purity. The smaller the particle, the more bioavailable it becomes, and the greater the surface area available for conversion to positively-charged, bio-active silver while within the body.* Argentyn 23 Bio-Active Silver Hydrosol has an unprecedented particle size as small as 0.8 nanometers.
Silver colloids have a color based on their particle size, ranging from orange to brown to yellow to clear as their size decreases. The property is called Surface Plasmon Resonance. Particles smaller than 5 nm are “subplasmonic” meaning they are clear and colorless solutions. Argentyn 23 Bio-Active Silver Hydrosol is a mixture of positively charged silver ions and silver nanoclusters with particles as small as 0.8 nm (nanometers). Color is visible when particles are larger (above 5 nm). A larger quantity of particles can also lead to visible yellow color as more particles absorb more light. Darker color is an indication of one or more of the following: even larger particles, compounds (salts or proteins), reduction of bio-active silver ions, or impurities. A smaller particle size is desirable due to greater surface area available for conversion to bio-active silver. Since visible color is an indication of larger particles, then visible color is your visual cue to less effective silver products.
The scientific literature states that it is the free silver ions (i.e. the positively-charged species) that are active and that there is a “negligible particle-specific” effect. In fact, researchers found that “the biological activity of nanosilver has been attributed to the associated silver cation and its soluble complexes.”
No, when following label directions or as directed by a healthcare professional. Argyria can occur after a lifetime exposure to all forms of silver exceeding 10 grams for the average adult according to the World Health Organization. The most dramatic symptom of argyria is the skin becoming blue or bluish-gray colored. Argyria may be found as generalized argyria or local argyria. Argyrosis is the corresponding condition related to the eye. Argentyn 23 Bio-Active Silver Hydrosol is free of proteins, salts, and other compounds and therefore poses no health hazard when used as directed.* However other colloidal silvers may contain these impurities therefore increasing the risk of causing argyria. Products with high parts per million (PPM) concentrations should be avoided as those products greatly exceed the EPA oral Daily Reference Dose (RfD)† for silver of 350 mcg (micrograms). Argentyn 23 Bio-Active Silver Hydrosol is the only professional silver supplement to have received a statement of safety from Dr. Dana Flavin; Founder and Executive Director; former Science Assistant to the Associate Bureau Director, Division of Toxicology, US FDA, Washington DC.
Many reports of immune support benefits have been received from satisfied patients and practitioners alike. Under the Dietary Supplement Health and Education Act (DSHEA), we cannot make specific marketing claims about diagnosing, treating, mitigating or curing any disease or condition.
No. This is a great question. A 2016 study by Wilding et al., from University of Michigan, demonstrates that silver does not alter gut microbiome diversity even at levels 2,000X the EPA Daily RfD.
Figure data from , Wilding, et al., (2016). “Repeated dose (28-day) administration of silver nanoparticles of varied size and coating does not significantly alter the indigenous murine gut microbiome.” Nanotoxicology 10(5): 513-520.
In accordance with the terms of the Wilding et al. study and as discussed above, we have no reason to believe that Argentyn 23 would alter the gut microbiome diversity.* According to Wilding et al., both good and bad bacteria are impacted equally, whereas prescription antibiotic cefoperazone disrupts the balance of bacterial species dramatically. Therefore, it is sometimes recommended to supplement with beneficial probiotics in the opposite time of day as the Argentyn 23 is taken, to assist with the balance of good bacteria in the gut microbiome.
