Protein supplements can be an easy and fast way to
metabolize nutrients, but depending on the breed, species, and condition, can
have different effects. In humans, protein supplements are not regulated as
harshly as for animals. This leads to substandard regulation and oversight
which can lead to contamination results such as Consumer Reports found in 2010.
"The amount of lead in a single daily serving of eight of the protein
supplements we tested would require that the products carry a warning in
California (Consumer
Reports, 2010) ".
They go on to say how teens are especially prone to marketing and that pregnant
women are the most at risk.
Agriculture, on the other hand, seems to be unanimous in
their pro-supplement support. A study by the University of Wales concluded that
“…there was no evidence that the welfare of cows fed a low level of concentrates
without supplementary feeding was compromised…[the only] adverse effects…was
when …calving [cows] were provided with a lactation supplement, because this
caused them to increase milk yield, which was not supported by increased food
intake, and…had increased levels of aggression (Phillips & Kitwood, 2010) ”. It is interesting that of the first few pages
of results online, not a single one said anything bad about animal supplements.
