One study, for instance, notes that people who are overweight or obese appear to have lower levels of vitamin B12 than those with a body mass index (BMI) that falls within the range considered to be normal. People who took vitamin B12 supplements of their own volition gained between 2.5 and 17 fewer pounds (1.27.7 kg) over ten years compared to those who did not take any form of supplementation with this vitamin
A randomized, double-blind, placebo-controlled trial in 191 older adults (75 years) with moderate vitamin B 12 deficiency (serum cobalamin concentrations of 107-210 pmol/L) without anemia provided participants with 1 mg/day of cyanocobalamin for one year (94)
