I have a problem with this campaign we are seeing recently of
news stories that supplements harm the liver, are a waste of money, and
so on, using the results of meta-studies that are pretty much no more
rigorous than the studies sometimes used to support false claims.
It
is not hard to pick out specific ingredients that do specific types of
harm and eliminate them, making a generalized ban on all supplements
unneeded.
Obviously controls are needed to
assure manufacturing quality and to be sure pills contain what the label
says they contain and nothing else. The campaign should be limited to
that. The effort seems to be to put nutritional supplements under a
very similar regulatory structure as now applies to prescription drugs.
I think this would be serious overkill. Individuals who feel they want
to buy nutritional insurance for things like folate and B12 and D3
should be able to do so, provided labels provide information as to
maximum doses. The convenience of packaging such supplements into a
single pill should not be interfered with.
I am suspicious
of popular press items that issues these warnings based on little
science (so called "meta-studies" where the studies reviewed are
selected seemingly to get the desired result) just as I am suspicious of
claims appearing in the popular press touting this or that chemical. I
am also suspicious of the fundamental regulatory mindset that ends up
reducing freedom and increasing medical costs.
