Nascobal is a synthetic form of vitamin B-12 in a nasally administered gel and spray.
Nascobal avoids the gastrointestinal tract by delivering vitamin B-12 directly to the bloodstream through blood vessels in the nose. This product is ideally suited for patients with such conditions as Crohn's disease, HIV/AIDS, multiple sclerosis, or pernicious anemia where absorption of B-12 from foods and oral supplements is either poor or does not occur at all.
