Mannitol is naturally present in a variety of plants. It is found in seaweeds and in the honey-like fluid that seeps from the bark of the manna tree (Frax inusornus). Mannitol is typically produced by the hydrogenation, purification, and crystallization of corn syrup.


Mannitol imparts a sweet, cooling sensation in chewable tablets and also serves as a natural means for binding ingredients together in tablets.
