Brief Summary
|
This will be a double-blind, randomized, placebo-controlled trial having 3 groups (plain yoghurt, B12 fortified yoghurt, B12 producing probiotic fortified yoghurt). Each group will have ~40 adult volunteers (18-50y). The period of supplementation will be 5 months.
This sample size is sufficient to measure vitamin B12 rise of 100 pmol/L (SD 80) above the baseline, with power of 80% and 5% level of significance; and accounts for 5 drop outs per group. Appropriate ethical approval has been obtained from the KEM Hospital Research Centre Ethics Comm ittee, Pune.
Data including Height, Weight, and venous blood sample will be collected at baseline and 5 months post intervention.
Data analysis: We will compare biochemical parameters (hemoglobin, red cell indices, plasma vitamin B12) in the different groups.
The sample size, dose and duration of the trial is based on our previous experience of community based, double blind trial of viamin B12 (crystalline) supplementation in capsule form (Deshmukh US et al). If fortified food form improves the circulating vitamin B12 status, it would provide a convincing mode for tackling widespread vitamin B12 insufficiency in our population
