Clinical and microbiological improvement in dog after metal and benzoate containing supplement mix

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.
