That is certianly one. Also offers competition for other trace elements - Fe, Mg, CU.
Speaking of the metals….how about Silver? Before you start swearing… I am using silver citrate at a low rate in a deo product, NOT as a preservative.
So I have read slightly conflicting thoughts amongst Phd’s on silver citrate in relationship to chelation. So I was curious if you could weigh in on the topic. One respected Phd basically said…without giving any details…. Silver Citrate and chelation don’t mix. The other one….which I consider one of the most brilliant minds on the planet said this: Silver ions carry a single positive charge and, according to the HSAB system, are ‘soft acids’ which have a high preference for ‘soft bases’ such as thiols. Simply put, silver is a …. poor ligand for most chelates and will not interfere with GLDA or EDTA. These chelates may bind to the surface of colloidal silver particles but, unlike zinc, the effect isn’t strong enough to neutralise anything.
I am typically using GLDA as my chelate…but also have sodium phytate on hand…. so could switch if need be.
