Julie,

Some people are deficient in B6, and either deficiency or overload of that vitamin can cause problems. It sounds like you may be one of those who needs the P-5-P type of B6 (the body can use it as is, and does not have to convert the usual pyridoxine hcl to usable B6.

B12 is safe, and the testing most doctors do cannot rule out deficiency.

There is a lot of good information on supplements. Take a look at the vitamin deficiency forum here, where you can search for info on individual ones. Most doctors don't have a clue about nutrients, so it's a good idea about to learn about them yourself.
