Due to low B12 & folate blood results I've been taking Jarrow Methylcobalamin B12, 5000mcg along with Jarrows B-Right Optimized B-Complex. I was having night sweats before I began taking these which stopped.
Recent blood test showed a great increase in B12 (1,000+) but not much progress in folate - I have therefore stated taking Solgar 400 mcg Folate Metafolin.
At the same time (about 2 weeks ago) I reduced the B12 (I'd done 60 days @ the 5000mcg) to Solgar, Sublingual Methylcobalamin, 1000 mcg - I changed brands as the Jarrows 1000mcg was lemon flavoured & I prefer the cherry flavour.
Over the past few weeks the night sweats have began again, I'm guessing this is all down to a lowering in my B12 again.
I was thinking of increasing my daily supplement to 2 x 1000mcg to see if this helps. Am I right in assuming that I need to take the B12 supplements forever now or will my body start to produce B12 itself after a while?
