Lucieb01,

If you were recently supplementing sufficient doses of B12 and vitD your levels will probably be good. To get a baseline result for B12 you would need to have stopped supplementing for 4 months, the length of time it takes for red blood cells to renew. VitD levels roughly halve every 60 days after stopping supplementing so you may want to retest vitD in 4-6 months.
