Grizz,

You summed it up nicely.

Velvetz: I would avoid calcium ascorbate if I were you. Ascorbic acid has studies showing again and again that it reduces the incidence of kidney stones. I suspect you would also be safe with sodium ascorbate, which you can either purchase [expensive], or make yourself by mixing in water one part of sodium bicarbonate with two to three parts of ascorbic acid [and wait until the fizzing/bubbling stops].

All just "grist for your mill," Velvetz,

Good health to us all,

David.
