It depends...: Work for what? If someone has B12 deficiency then B12 shots definitely "work" to treat the deficiency and resultant anemia/neurological symptoms. However, many who are not deficient get B12 shots for fatigue and other non-specific symptoms. While many people feel better after B12 shots, there has been little research to show if it actually helps. See http://www.Medscape.Com/viewarticle/585589.
