An enteric-coated caffeine delivery system includes a caffeine-containing core and an enteric coating made of methacrylic acid copolymer. The caffeine delivery system may also include a subcoating. The caffeine delivery system resists disintegration and release of the caffeine at a pH less than 5, but disintegrates rapidly to release the caffeine at a pH greater than about 6.
