Vegan means no firm animal gelatin as capsule shell. Corn starch used for this, among other things. Modified starch means that it has extra branching and therefore becomes stronger. Together with glycerol and carrageenan (seaweed extract) this makes the shell. So modified has nothing to do with genetically modified (which we would never use). Since linoleic acid is not active, but must first be converted into ARA (arachidonic acid), which does not happen 1:1, the ratio falls even more strongly in favor of Omega-3.
