R.P. Scherer has been granted a U.S. Patent, 6,403,119, for vitamin containing capsules that are discoloration-resistant. It includes a vitamin composition encapsulated in a soft or hard shell capsule (the composition comprises water soluble vitamin particles suspended in a fill liquid). The water soluble vitamin particles are coated with a material that is substantially insoluble in the fill liquid and the shell of the capsule, but soluble in the gastrointestinal tract of a mammal. The coated water soluble vitamin particles are of a size that are suitable for encapsulating as a suspension in capsules.
