ut for dozens of other nutrients. Otherwise, why would modern

New functions of vitamins and minerals
are constantly being discovered
Richard G. Shields, Jr., PhD
Summary: “As new functions are identified for existing nutrients, it is possible
that requirements to optimize these new functions will
change as well... There’s increasing acceptance that an optimal range
rather than a minimal requirement is appropriate.”
Dr. Wysong’s comments: So if regulatory minimums are not appropriate,
and requirements change (which they always do), what business
does the pet food industry have claiming foods that meet
minimal requirements to be “100% complete”

Effect of increasing dietary vitamin A
on bone density in adult dogs
J.L. Cline, PhD; G.L. Czarnecki-Maulden; J.M. Losonsky; C.R. Sipe;
R.A. Easter, PhD
Summary: “The effect on bone density of feeding various concentrations
of vitamin A in a canned dog food product was investigated... Diets
were fed up to 1 yr. Computed tomography was used to determine
bone density... There were no differences (P > .10) in tibia bone or
marrow density in any of the dogs fed the various concentrations of
vitamin A... These results indicate that concentrations of vitamin A
three times the recommended maximum safe amount (71,429
IU/1,000 kcal ME) are not detrimental to normal bone health
in dogs.”
