Hi there...you can take tablet becosules one tablet daily in the afternoon for one month for vitamin b12 deficiency. Take tablet uprise d3 60000 IU one tablet per week for 8 weeks for vitamin d deficiency. Firstly it is important to see why the doctor had advised you these tests. You might be suffering from their systemic manifestation. So consult the doctor who had advised you these tests with the reports. They will advice you regarding further management.
