Chemically, mannitol is an alcohol and a sugar, or a polyol; it is similar to xylitol or sorbitol, and is poorly absorbed by the body. This chemical has a tendency to lose a hydrogen ion in aqueous solutions, which causes the problem of solutions becoming acidic. For this, it is not uncommon to add another substance to adjust the resultant pH imbalance, such as sodium bicarbonate. Mannitol is used in vaccine production for it’s humectant (moisture trapping) properties, and very low hydroscopicity (does not attract moisture from the air).

CSPI has petitioned the FDA to require foods containing one or more grams per serving of sorbitol or other sugar alcohol, such as mannitol, to carry a more informative notice. CSPI’s petition recommends that labels state: “NOTICE: This product contains sorbitol, which may cause diarrhea, bloating, and abdominal pain. Not suitable for consumption by children. To protect yourself, start by eating no more than one serving at a time.”

There Is little or no Information about this substance being injected directly Into the human body. Adverse effects, both short and long-term, are unknown.
