The IMD Laboratory has a new way for testing your vitamin b status, which I find quite interesting.
Normally you would have the quantity of a vitamin in your blood tested. But there is now a way of testing the actual bioavailability of said vitamins.
What they basically are seeming to do is to draw your blood and to feed it to bacteria. The bacteria will start growing until the nutritional value of your b vitamin is used up. You could basically have normal Vitamin B12 levels but the vitamin b12 in your blood may not be very bioactive and thus not nourishing enough for the bacteria or your very own cells.
Their website does a much better job in explaining the whole procedure of course:

I had this test done and the results came back today (reference in brackets):
Vitamin B1: 26.7 (>39.8)
Vitamin B2: 32.3 (>85.4)
Vitamin B6: 7.7 (>10.1)
Vitamin B12: 296 (>358)
Folic Acid: 119 (>100)
Biotin: 1628 (>1250)
Niacin: 7.84 (>17)
Pantothenic Acid: 26.5 (>36)
So personally I am quite deficient for most of the b-vitamins.
I am not sure how available this kind of testing is worldwide. Maybe it is worth looking out for it for some of you.
Best wishes
