After extreme tiredness I paid for some private blood tests...iron profile came back within normal ranges but vitamin b12 was 188 pmol/L (normal range 250-369) and vitamin D (25 hydroxy) at 23-(normal range 50-200)
The interpretation of these results is vague and just says could benefit from supplementation..but what does this mean ? Would a general multivitamin suffice or is there any good places to buy these separate vitamins in higher doses? Thanks
