My rhymin' is a vitamin held without a capsule
A vitamin “without a capsule” goes down more easily; it is also more pure, less adulterated. Nas is arguably advancing both ideas about his own style; it goes down more easily, meaning it is more accessible to the average listener, and it is more “raw,” thus closer to the streets than the rap of manufactured studio gangsters.
Nas also alludes to his stage name at the time, Nasty Nas, since chewing on a multi-vitamin produces a really nasty taste in your mouth.
