Does anyone know an OTC source of fumaric acid? I have been looking all over to no avail. If not, does anyone know of any sources (excluding chemical
suppliers) that sell small amounts of it? The one source I have been able to find is some place on ebay selling half kilos and I rather not have
anything to do with ebay.

There are not many, if you mean "I can walk into a retail store and buy it" It's used as a souring agent, like citric and other 'fruit' acids, but
that generally is in commericial productio where they want to sell you 25 Kg sacks of it. The other big use that I know of is in polyester resins,
again not something you whip up a liter of on your own (from the basic monomers).
The best bet is large health stores, where you might find something like this
Fumaric Acid 500mg 90 Caps

That's rather expensive, about what I could have bought one of those 25 Kg bags for when I looked some time ago.
I suspect it's not worth trying to extract it from one of various mixtures that contain it, they look to be complex and have many ingrediants that
will act too much like fumaric to be easy to separate.
