A couple of pertinent notes influenced by perusing *Laurel's
Kitchen*, my favorite nutritional reference:

Vitamins interact, with each other and with minerals.  For
example, one's requirements for B6 and calcium are proportional
to the amount of protein in the diet.  Each B-complex vitamin is
considered to be virtually useless without the others.  Rather
than megadosing a single vitamin, it is more prudent to take
multi-vitamins.

Because of the influence of differing diets and lifestyles on
requirements, the RDA of vitamins and minerals is often set
high, with hopes of covering the worst-case.  An example is that
of zinc (15 mg), which is extremely difficult to get without
mineral supplementation.  However, this is NOT the case with
thiamine (B1, RDA of 1.0 mg).

For the curious, *Laurel's Kitchen* is a cookbook/nutrition book
by Laurel Robertson, Carol Flinders, and Bronwen Godfrey.
