Vitamin B12 Overdose in a Vegan Diet Long-term implementation of the vegan diet without taking vitamin B12 supplements is strongly correlated with a deficiency
Patients seeking B12 testing or treatment should consult their GP, who can arrange appropriate blood tests (serum B12, full blood count, folate, and if indicated, intrinsic factor and parietal cell antibodies) and prescribe treatment if deficiency is confirmed
The contraindications relate to both the semaglutide and cyanocobalamin components, and careful consideration must be given to each ingredients specific safety profile and potential risks
