In brief: Bioavailability vs..

Bioavailability may vary depending on the source of your vitamin supplement.
Potency and purity however play significant roles in the efficacy of the supplement, regardless of source. Find the cheapest vitamin that approaches 100% rdu (recommended daily allowance) and save money over "natural source" ones. There are of course significant benefits from eating healthy foods in general.
