So, since I jumped back in to a methyl protocol, about 1.5 weeks ago after a few week hiatus, I have near constant burning/tingling. What's confusing is that the burning and tingling is one of my dominant deficiency symptoms so it is hard to tell if I am not taking high enough dose to make the tingling go away or if the methylation is causing Potassium deficiency which I understand can cause itchy/tingling/burning skin. I am currently taking 800mg-1600mg metafolin, B complex, 1000mcg methyl (Jarrow) and tons of co-factors. Now, this morning I woke with no tingling, but by mid morning it arrived. I ate a banana and then took the folate. An hour passed, I took the B12 with some other food I am not remembering now. The tingling got a little worse. Then I ate about 14 oz of potatoes (somewhere around 2000mg potassium) and it didn't fix a thing. Certainly if such a high dose of potassium didn't make the tingling subside it has to be caused by something else?? Anyone have thoughts?!
