Nullo Internal Deodorant Tablets are taken daily to reduce body odors such as bad breath, foot odor or underarm odor. Nullo Internal Deodorant Tablets also claim to reduce fecal odor. Colostomy patients may find it helpful to dissolve Nullo tablets in their colostomy pouches to reduce foul odors. Nullo Internal Deodorant is used to control body odors safely and effectively. Clinical studies show that Nullo controls body odors due to problems with bowel control, the performance of a colostomy or ileostomy, and/or fecal incontinence. To quell colostomy and ileostomy odors, place one or two tablets in your emptied colostomy pouch each time it is reused or changed. Nullo can also be used by hunters, to prevent animals from picking up their scents. Each bottle of Nullo contains 135 caplets. Each daily serving (3 caplets) contains 100 milligrams of a Chlorophyllin Copper complex.
