Note
The -ing form does double duty. In "she is supplementing her income" it is the verb in progress. In "supplementing your diet is easy" it heads a noun phrase but still takes an object. It usually pairs the thing being topped up with what tops it up: supplementing a salary with tutoring, a diet with vitamins. The base word supplement is also a noun, but this form comes only from the verb.
