All caffeine shares the same molecular structure (C8H10N4O2), but how it's produced and what comes with it matters. Natural caffeine extracted from coffee beans (Coffea) is plant-derived and contains naturally occurring chlorogenic acids — bioactive compounds with antioxidant and metabolic properties. Synthetic caffeine anhydrous is manufactured from urea and chloroacetic acid in a chemical synthesis process. PurePump uses 200mg of natural caffeine from coffee bean (at 2 scoops) for clean energy from a natural source.
