I have been having a number of B12 related symptoms, took supplements and felt better. I stopped supplements on the 18th June & had 4 months clear of fortified cereal & so on to check if I have a deficiency.
I did an active finger prick test & my level on the 14 September had dropped to 67.2 (range 37.5-188)
However, I have just done an finger prick advanced thyroid test on the 16th & B12 is now up, & 94.2 (same range)
Anyone have any idea why this down & up?
Thank you.

I am very impressed that you have written dates, 18th June and 14 September.
I will explain if I put a heart monitor on.
I am lying on my bed - my heart rate is 72 bpm.
I stand up it very briefly rises to 92 bpm and then goes back to 72 bpm.
I walk around to tidy my messy home, my heart rate goes up incrementally to 98 bpm. Then back down.
I prefer to do housework to music, so put some rock music on to do the hoovering, my heart rate rises to 84 bpm.
I decide that I want to get my whole home spick and span, so crank it up a notch. Music blaring, getting hot and sweaty, hoovering like there’s no tomorrow. My heart rate is now 134 bpm. I do this for 20 minutes.
I admire my handiwork, put vacuum away.
Put the kettle on, grab a cuppa, loaf on my sofa.
After 5 minutes my heart rate is 101 bpm.
10 minutes it is 88 bpm.
After 30 minutes it is 69 bpm.
See the variability of it.
How do I feel. I have achieved but I need a shower but I am too tired. I’ll rest for an hour. Then undress, shower, dry, clothes on.
