Hi all ... I'm a bit confused as despite the extraordinary amount of sun I am getting due to our very long & hot summer my Vitamin D levels have dropped since last November from 93 to 58 ... I have had 2 B12 injections since November and have been out in the sun everyday and am as brown as a berry! In fact it's the best tan I've had for many years! The beginning of last year my Vitamin D was 44 but after sitting out in the sun all summer it rose to 93, but this year it doesn't seem to be going up.
My Ferritin & Folate have also dropped quite dramatically but am assuming this is because the B12 uses both of those?
Ferritin was 147.4 (not sure why it was so high I never supplemented?) dropped to 60 now.
Folate was 19.2 now dropped to 9.6 even though I take 200ug folic acid everyday
So I 'm wondering what the relationship is between B12 & Vitamin D if any?
If anyone can shed any light on this I'd be most grateful?
