Is the shine off Chromium
Picolinate? 
Chromium Picolinate has become the subject
of the latest national health scare. A much-publicized study
in the December 1995 issue of FASEB Journal, a publication
of the Federation of American Societies for Experimental Biology,
says that the popular dietary supplement may cause cancer
– an assertion that’s virulently denied by its
manufacturers. |

What is Chromium Picolinate?
Chromium picolinate is a compound of the trace nutrient chromium,
which the body requires for the regulation of blood sugar, and
picolonic acid, an organic substance that can increase the body’s
absorption of minerals. Many people don’t get the recommended
daily intake of 50 to 200 micrograms of chromium picolinate in
their diet (it’s found in liver, cheese, whole grains, dried
beans and some fruits and vegetables). A small amount of research
has indicated that chromium picolinate may help build lean body
tissue and metabolize fat – causing it to become a standard
supplement among bodybuilders and health-food enthusiasts.
Recent Studies of Chromium Picolinate
But in the recent tests, conducted at Dartmouth College and George
Washington University Medical Center, Chinese hamster ovary cells
exposed to the substance has three to 18 times as much chromosomal
damage (an indication of cancer-causing potential) as cells exposed
to other chromium compounds. (that doesn’t necessarily mean
the other compounds are safe, the researchers said, since they
didn’t look for other types of DNA damage.) “although
chromium picolinate supplements have been assumed safe for human
use, this study demonstrates that further investigations are warranted
to verify their safety,” they wrote.
The Chromium Information Bureau, a producers’ trade group,
disagrees with the findings, saying that the serum concentration
or blood level, required to achieve chromosomal damage by chromium
picolinate was much higher than the amount a person would get
from a common 200-microgram tablet. “The study doesn’t
bear any relationship with real life,” says the bureau’s
executive director. But Dartmouth research associate argues that
“tumors develop in tissues, not in serum, and the chromium
picolinate levels in tissues can be a hundred times higher than
those in serum.”
In Summary about Chromium Picolinate
Still no one, including the study’s authors says that people
should stop taking chromium based on this research. All agree
that further research of chromium picolinate is required before
more can be known about the chromium picolinate supplements’
safety. Originally written by Kallen for Men’s Fitness Magazine.
