FYI Vintage 1989 SlowMag launch:
 

I was on the internet alot yesterday and found this:

It is an ad from 1989 when Searle (now brought out by Pfizer),
launched SlowMag to doctors. It has always been OTC but still
the major advertising was to doctors and pharmacists.

SlowMag was sold to Purdue before the Pfizer buyout.
This is the current website:
http://www.slowmag.com/

I thought this was interesting so I copied it for here.

BTW the current website has some nice tools to help with
choosing foods that provide magnesium. This site is really nice
and more helpful now. ;)

Mag. is so important for everyone ill or healthy. I take several kinds. Very important for Dysautonomia for sure.
