current posting warns of possible liver toxicity with kava. These
warnings are based on 29 cases in Germany and Switzerland where
patients taking kava experienced serious liver disease. In 18 of
those cases, patients were also taking pharmaceutical drugs known
to cause liver disease. One death and four liver transplants occurred
among these 18 cases.

excessive levels of B vitamins
its latest round of testing of B vitamin products, ConsumerLab.com
found that some brands contain levels of niacin and vitamin B-6
higher than the tolerable upper intake level (more familiarly known
as a safe upper level). However, ConsumerLab did not "flunk" these
products from its list of those passing its testing. It did note
which products exceeded the upper level.
SupplementQuality.com reported in our feature article RDAs
and Safe Upper Levels: Solid Science or Bureaucratic Bias, safe
upper levels are based on sketchy data, questionable assumptions,
and political bias. The upper level for niacin was set to avoid
skin flushing, which is probably the most benign side effect for
any substance that people can ingest. However, significantly higher
doses of niacin can lead to liver toxicity. Concerns about exceeding
the upper level for vitamin B-6 are also more serious; large doses
can lead to permanent neurological damage.
therapeutic dosages for treating illnesses are sometimes higher
than the tolerable upper intake level, which is designed to protect
healthy people. Consumers who choose to take high dosages of any
nutrient should always consult a doctor who is knowledgable about
nutrition -- both deficiency problems and symptoms of toxicity.
