My lips feel numb on occasion. Both top and lower have a strange numbness. This seems to come and go with me and I have yet to find the culprit deficiency I suspect there is. In another thread Stridor mentions for him B2 helped, another thread someone mentioned B12. Yesterday I took a small dose of each with some zine and that seemed to help. But I'd like to know if anyone has figured this out when taking methylation supps?
