Q. I was excited to read about canker sores in your column. They are also called aphthous ulcers.
I have suffered for many years with extremely painful mouth ulcers. I read a magazine article that mentioned a study done at Ben-Gurion University in Israel. They found that patients given 1000 micrograms (mcg) of vitamin B12 for a six-month period experienced a substantial decrease in break-outs or even a complete cure.
I have been on this regimen for six months to date, and if I experience any sore, it lasts for only one day, then disappears completely. I recommend that people who have recurrent canker sores check with the physician first, and then consider 1000 mcg of vitamin B12. It has made a major difference in my life. No more suffering, no more pain.
A. We tracked down the study you read about. It was published in the Journal of the American Board of Family Medicine (Jan-Feb., 2009). The investigators used a sublingual (under the tongue) form of vitamin B12. They concluded, “Vitamin B(12) treatment, which is simple, inexpensive, and low-risk, seems to be effective for patients suffering from RAS [recurrent aphthous stomatitis, or canker sores], regardless of the serum vitamin B(12) level.”
