Several British studies
have shown deficiencies in vitamins B1, B2,
B6, B12, iron, or folic acid in a
significant number of canker sore sufferers.
Many readers have also e-mailed to say that
they believe vitamin and mineral supplements
have reduced the incidence or severity of their
canker sores. Others, however, see no effect.
A good place to start is by seeing your
doctor and having her take blood tests to
measure your levels of B vitamins, folate, and
other minerals. If you are deficient in any of
these, your doctor can suggest appropriate
supplements (It is not a good idea to take an
excess of vitamins or minerals as toxicities
can occur when you take too many).
Other readers have reported that a daily
supplement of the amino acid lysine has
dramatically reduced their occurences of canker
sores. Please consult your physician for an
appropriate daily dosage.
