GlyphoBlock: bind the glyphosate, escort it out?
No study of the product, or of the idea.
GlyphoBlock sells “3 patented probiotic strains” said to bind glyphosate — the weedkiller found on some grains — before it is absorbed. Short answer: we found no study of GlyphoBlock, and no study of any probiotic binding glyphosate, in people or in animals. A patent shows who owns a strain, not that it works.
