A B complex has much more than B1 and B6. Some of the B's work to activate each other in body.

B2 activates B6...to pyridoxal.

I don't see why a B6 in addition to a Complex is necessary.

This formula is quite good, and many over the years have used it with success. It has been reformulated to have active B's in it, which do not appear in most others. It is a modern trend to add these now.

This is also at iherb I believe...but not many local outlets carry it yet.

B6 pyridoxine may build up in people who do not properly activate it to P5P... (pyridoxal). It is this that may be the culprit in high B6 levels...and the symptoms that arise. Pyridoxal is taken up by muscle quickly and doesn't remain in the serum for long.
