supplementer

One who augments

A supplementer is someone or something that supplements—that adds to or completes something else.

The word appears most often in contexts involving nutrition or education: The company markets itself as a supplementer of essential vitamins.

It's a functional but infrequent formation; supplement as a verb usually suffices.
