Connection between benfotiamine and vitamin c?


Senior Member
I have a particular symptom that's helped by one or the other. It's a pain on the back of my neck that spreads up the back of my head to my forehead, between my eyebrows. Seems like a tension headache but it's also accompanied by neurological symptoms in the same areas.

I try vitamin c (1g), if it doesn't work, I try benfotiamine (150mg), and it goes away rather quickly -- within about 30 minutes. It seems to come back in about 8 hours and the same process makes it go away again. I've been trying to find a connection between vitamin c and thiamine that would explain it but I'm coming up short.

Any ideas? Thank you
