Chromium - Topic Overview
Is chromium safe? continued...
Antacids (including calcium carbonate) interfere with the
absorption of chromium.
Being exposed to high levels of chromium
on the job (such as in metallurgy and electroplating) has been linked not only
to kidney damage but also to lung and other cancers as well as skin conditions
eczema and other inflammations of the skin.
The U.S. Food and Drug Administration (FDA) does not regulate dietary
supplements in the same way it regulates medicines. A dietary supplement can be
sold with limited or no research on how well it works or on its safety.
Always tell your doctor if you are using a dietary supplement or if you
are thinking about combining a dietary supplement with your conventional
medical treatment. It may not be safe to forgo your conventional medical
treatment and rely only on a dietary supplement. This is especially important
for women who are pregnant or breast-feeding.
When using dietary
supplements, keep in mind the following:
- Like conventional medicines, dietary
supplements may cause side effects, trigger allergic reactions, or interact
with prescription and nonprescription medicines or other supplements you might
be taking. A side effect or interaction with another medicine or supplement may
make other health conditions worse.
- The way dietary supplements
are manufactured may not be standardized. Because of this, how well they work
or any side effects they cause may differ among brands or even within different
lots of the same brand. The form of supplement that you buy in health food or
grocery stores may not be the same as the form used in research.
- Other than for vitamins and minerals, the long-term effects of
most dietary supplements are not known.
