This is essentially correct. Vitamin capsules are generally made from gelatin. Vegan ones are generally made from tapioca starch, glycerol, agar, etc. The idea that vitamin capsules are derived from hydrocarbons is probably just HMPC (hydroxypropyl methylcellulose, where the hydroxypropylation is done with propylene oxide), which seems rare compared to gelatin.
