As far back as June 2012 I issued warnings about dietary
supplements. People see them as an easy
solution to an insufficiently healthy diet, eating on the run and not being
particularly careful about meals.
Supplements are readily available, promoted by health food stores and
chain pharmacies in vast displays. The
good old vitamin pill has been considered a type of nutrition insurance for
decades. Since they don’t require a
prescription, most people tend to consider them harmless – good for you with no
side effects.
The facts that few pay attention to about lower standards
than prescription medicine, unanticipated interactions, questionable purity and
the lack of testing by the FDA (until after a problem has been reported) among
others means that it is periodically important to renew the message when new
information becomes available.
“ConsumerLab.com, which has tested over
4,500 products since November 1999, has found that, through July 2015, 20% of
the vitamins and minerals, 43 percent of the herbals, 21% of other supplements,
and 24% of nutritional powders and drinks failed their evaluations. The most
common problem was too little or none of the main ingredient. The other
problems included too much active ingredient; the wrong ingredient; potentially
dangerous or illegal ingredients; contamination with heavy metals;
"spiking" with unexpected ingredients; poor disintegration (which
affects absorption); and misleading or incomplete product information.”
At the ConsumerLab site, I found more
information specifically about vitamin tests: “If
you're worried that you don't get enough nutrients from your diet, you might
want to hedge your bets with a multivitamin. But what's really in that pill,
powder, or liquid? If you're not careful, you might not get what you bargained
for. In its latest review and quality rating of multivitamins, ConsumerLab.com
found defects in nearly 40% of multivitamins it selected for testing. Here are
some of the discoveries:
·
One popular general multivitamin contained
nearly 2.5 times its claimed amount of vitamin A in the retinol form. Too much
of this type of vitamin A can be harmful.
·
12 multivitamins provided less vitamin A,
vitamin C, or folate than claimed, some with less than 30% of the
listed amounts. These include a prenatal vitamin and products for men, adults
(general), seniors, and even pets.
·
Tablets of a women’s multi and a general adult
multi failed to break apart within the required time -- indicating they
may not fully release all of their ingredients for absorption.
·
One pet multivitamin was contaminated with lead.
·
A range of multivitamins contained more than the
upper tolerable limits of niacin, vitamin A, magnesium, and/or zinc.”
They also found wholesale club and discount retailer
versions of popular multivitamin and mineral supplements with the
same ingredients at a considerable saving of 40% to 70%.
It seems all is not as it appears in the supplement
business, even the trusted multivitamin side.
The FDA steps in only after people have been adversely affected and the
FTC steps in only if supplements falsely claim health benefits. This situation calls for care and critical
thinking. Better yet, with a balanced diet most can forget the vitamins and save 100%!
