Can supplements be harmful?|
Supplements may be helpful to some people--yet
more studies need to be conducted, to be sure.
However, do not take mega doses. Megadoses of
vitamins (and other supplements), in particular Vitamin A
(which is stored in the body) can be very harmful,
so be careful. There are even studies that show
that beta carotene supplementation is questionable
and can even be harmful, particularly in excess.
Moderation is a good idea.
Used incorrectly, many of these substances can be
harmful. Did you know:
megadoses of vitamin A can cause bone pain,
birth defects in babies, hypertension? |
long-term excess vitamin E can cause low
sperm count, degeneration of testicles,
Megadoses of vitamin C can cause gout, kidney stones,
and can interfere with white blood
cells' ability to kill bacteria, making infections
worse rather than clearing them up?
Nearly everyone takes vitamins, minerals,
supplements or medicinal herbs. If you are thinking of taking supplements,
it pays to be cautious. Here are a few tips for you before you decide to purchase them.
Before taking a supplement, find out what
evidence supports its advertised benefits-and dangers.
It is a good idea to glean information from a variety of
sources, not just one book or magazine article. |
Do Not Overdo It: Learn what scientists know about
safe dosages and do not exceed them. In particular, do
not use a large variety of herbs on a regular basis.
There are no data on the safety of any botanical when
combined with another herb or drug.
Do Not Trust the Label: It can make any number of
claims that are not backed by good science or, in some
cases, any science at all. Do pay attention to the print
that reads: "This statement has not been evaluated by
the Food and Drug Administration."
Discuss Supplement Use With a Doctor: Inform a
doctor about supplement use, including vitamins.
Pregnant women and people with genetic defects that
impair their ability to metabolize a nutrient should not
use any supplements without approval or
recommendation from their physicians.
Consider Food: When possible, it is generally better to
get nutrients from food than from supplements.
Consumers should learn what foods supply those they
need most and include them in their diet.
Report Adverse Reactions to FDA: Anyone who
believes he or she has symptoms related to dietary
supplement use should call 1-800-332-1088 or
