Karen's point about other nutrients is an important one. It has been mentioned many times, but it is worth mentioning again.

When one is low in B12, and that person begins to get the B12 they need, if they are also low in one or more other nutrients and the body begins drawing heavily on those nutrients to make repairs, there can be additional or worsening even beyond that of the common process of healing.

Iron and potassium are two frequently drawn upon heavily, but others are important too.
