Does Questran powder come in an unsweetened, unflavored form?

Yes, it does. Go to any compounding pharmacy and they will be happy to order you
pure cholestyramine powder. Be warned however / your insurance may not cover it
and it smells just like dead fish. It also is the equivalent of drinking sand when you
mix/drink it --- but it does not taste like fish or anything. I use this because I have IC
a bladder condition and cannot take artificial colorings which both forms of
Questran have. I don't care about the fishy smell or the texture. Life with bile salt D
is much worse than that! 11/16/2016

I don't think so. They all have sucrose and orange flavor.
