I'm probably being thick here :cool: but I don't understand the difference between mcg and μg this is in relation to vitamin dosage. I take B12 which shows 500 μg on the tub, but on line any info about vitamin B12 gives dosage in mcg. Can you help me out folks ?

they are the same - one millionth of a gram. The funny Greek symbol is the international symbol, but mcg is more normally used in the UK and USA.
