I am not sure @derek . I guess there is no way. All i know is that my parents dogs health improved dramatically on it and she is still here thriving! It did amazing things for my gut as well as skin. You could just get organic silica online if you were concerned. I am not sure of the brand, as I put it into another container, says made in the USA.
I feel your pain! I found that increasing sugar made my skin worst. Especially as my body wasn’t used to it. I Highly recommend 1 tsp of human grade Diamateous earth (sorry about the spelling there) it is just a great form of silica but it made such the difference. Normally I would get acne typically before my period or eating a lot of sugar and this cured that, if i get any they are small and manageable. Warning though the first couple of days taking it will make your skin break out, but that’s it! and then your skin begins to look amazing!
