Hmmm…would that process leave silica in the milk? They were tested in a lab and silica was found. I actually think Haidut paid to have several organic brands tested and the lab found silica.I missed this in the initial article that started this thread, in regards to silica being added to milk. I have never heard that before. Louis Kervan did research on this subject and concluded that dairy cows converted the silica in the grass that they ate into calcium that was found in their milk, he called this process biological transmutation. https://ecands.bio/down/resources/CalcDecptn.pdf
