Biotin is a water soluble vitamin generally classified as a B
complex vitamin.
Although Biotin deficiency is VERY rare, human deficiency has
been demonstrated for two different situations.
Prolonged Intravenous feeding without Biotin supplementation
and the biggest reason lately has been, the use of Raw egg
whites by "body builders"
and those on a "special" diet regimen touting the drinking of
Raw egg whites.
Avidin is a protein found in raw egg whites and it binds Biotin
preventing its absorption.
Symptoms of deficiency are hair loss, scaly red rash at the
nose, mouth and genitalia.
Depression, lethargy and numbness of the extremities.
Biotin is not known to be toxic and doses up to 200 mg/day are
well tolerated.
As non of the current drugs used to control crohns disease are
known to be contra indicated with usage of Biotin you should be
OK.
As always, speak with your crohns management team to verify this
advise.
