Screening for Cobalamin Deficiency in Geriatric Outpatients: Prevalence and Influence of Synthetic Cobalamin Intake

Abstract

Regular use of a multivitamin/synthetic Cbl source confers some degree of protection against Cbl deficiency in older adults. The relatively high prevalence rates and benefit of synthetic Cbl intake in this study reinforce recommendations that older adults should be screened for Cbl deficiency and should incorporate synthetic sources of Cbl as part of a balanced diet. Appropriate screening intervals and the optimal dose of supplemental Cbl to prevent Cbl deficiency remains to be determined.
