I agree that companies will do what ever they can to boost the market of their products, but ionic silver studies are not present in their proof of product effectiveness.
Purest Colloids has their own lab reports for proof. Ionic silver can do the same.
In my experience, mesosilver works externally on mrsa ulcers but doesn't work internally to stop colonized mrsa in the nares.
Only iodine worked to erradicate internal mrsa colonization in the nares with an immediate drop in WBC count.
However, killing the mrsa in the nares always seems to flare my mom's autoimmune disease (Microscopic Polyangiitis).
