We are accustomed to thinking in terms of a daily figure for vitamins and minerals. Sometimes it is the RDA and sometimes it is a figure much higher. The main street attitude is that a balanced diet is all that is required.

Maybe that is so and maybe it isn't, but there are at least two other questions that could come from the situation.

1) What if we are a rare bird that needs more, say, B12? Say a hundred times more? Or ten times more magnesium? Or both? How would we know?

2) What if we need the same amounts in our systems as everyone else, but we are only able to absorb a tenth as much? Or lack the enzymes to process it once absorbed? How would we know?

The reason for considering this include the fact that stomach acidity alone can affect this and there may be a dozen others. And the symptoms of deficiencies of the Bs alone sure do mimic PD in many ways.
