Abstract
Vitamin B12 deficiency is occurring in younger adults at rates that parallel that of the elderly. This study evaluated the efficacy of vitamin B12 supplementation through either cereal (> 4 serv/wk 100% DV) or B12 supplement (1000 mcg/d) in 137 women identified at time of annual exam as having low-normal plasma B12 level (200-250 pg/ml). Significant (p < 0.05) increases in mean plasma vitamin B12 was observed in all subjects after 3 months of either type of supplementation. Subjects whose baseline B12 status was < 200 pg/ml did not increase B12 levels to the 250 pg/ml benchmark. Nurse practitioners are positioned to effectively prevent the risk of vitamin B12 deficiency in younger adult patients.
