Benzoic acid occurs naturally in foods considered healthy but it tends be a concern when added to more synthesized foods. While it is added to some dog dental products as an active ingredient, larger uses do not appear to be well described beyond product preservation. This work documents the use of a supplement mix containing benzoate as an active ingredient along with more well appreciated components such as niacin, riboflavin, and tin-silver. It is described in the context of one dog, Beauty, in whom the response was best correlated. She had been lethargic and had some response to B-12 after she was found to be anemic but then she had reduced food intake and substantial weight loss. Addition of this supplement mix to her intake improved her eating and reversed significant weight loss for several months even as her underlying diseases remain unknown. Experience with other dogs is noted but it is less detailed o compelling. 16s rRNA analysis on fecal and vomit/spit-up samples demonstrated some favorable changes during recovery. For example, the observed increase in fecal Faecalibacterium prausnitzii is an objective of some other related research. Any role for benzoate is unclear but this may be an interesting case for hypothesis generation involving a therapeutic role for each of these ingredients. A "product" version of this ingredient mix is discussed.
