This client's most notable complaint was persistent mouth ulcers. Upon their DNA results, we increased B12 intake more than any other vitamin. This was with Methyl B12, which is a superior form of B12. We also increased their dietary intake.
Although the client's last blood test showed a low normal B12 serum level. Being a poor absorber you can still be deficient within this range, as a functional B12 shows up as high inflammation levels (homocysteine).
Finally they lowered their alcohol consumption, particularly by not going over the binge threshold of 8 units.
Now a month later the ulcers have not made a return!
