You are lucky, can't even get a script for it on Group Health/Kaiser. I have to buy OmegaVia for $55 a month.
I did get a prescription from Kaiser (outa pocket) and you may not be missing much for less that half what I pay.
Dosage for the dude that asked; 2 grams twice a day w/ meals. Though, if I get caught eating out w/o my V, I take it when I get home. No issues well after meals and before bed for me, at least...
