Thought I would share this from a source:
"Serriasil is a combination of clay based minerals from the Sierra Mountains in the US. It looks like it has been subject to one controlled trial in those with mild to moderate knee OA, but the authors concluded that In all sierrasil treated groups there was a significantly faster onset of benefits from initial values (evident from week 1 to 2) compared to placebo (first evident at week 6) but at the conclusion of the study differences between groups was not significant.
While their product does have an NPN number with Health Canada, they dont list their product ingredients on the governmental registration but online it contains:
Sodium + 12mg
Iron ** 1.2mg
Silicon ++ 1.0mg
The fact that it contains aluminum (a neurotoxin) and that the long term blinded results are not promising, I would not recommend this product."
I have no filter …
