---|---|
Active Comparator: hydroxocobalamin injection 25 patients receive the standard treatment of a vitamin B12 deficiency: hydroxocobalamin injection |
Drug: Hydroxocobalamin
patients are treated for 6 months with hydroxocobalamin. Patients will be treated with once a dose of 2000ug, after that treatment will be continued with a dose of 1000ug per 2 months. At timepoint 0, 2, 4 and 6 months after treatment vitamin B12 will be measured. At timepoint 0 and 6 also homocystein and methylmalonic acid will be measured.

Active Comparator: FitForMe vitamin B12 tablets 25 patients receive a daily dose vitamine B12 tablets |
Drug: FitForMe vitamin B12
patients are treated for 6 months with a daily dose of 1000ug vitamin B12 tablets. At timepoint 0, 2, 4 and 6 months after treatment vitamin B12 will be measured. At timepoint 0 and 6 also homocystein and methylmalonic acid will be measured.

Outcome Measures
Primary Outcome Measures
- reduction in patients with vitamin B12 deficiency [6 months after initiating therapy]
Before starting treatment vitamin B12, homocystein and methylmalonic acid will be measured. Two and 4 months after starting treatment vitamine B12 levels will be measured. At 6 months after initiating therapy again vitamin B12, homocystein and methylmalonic acid will be measured.
