Welcome, dd2by2 . . . what other readings have you had besides the one fasting BG of 109? Do you have a meter of your own or was this finding from a lab? How recent is this reading? I think you prob'ly need more to go on than just this one sample.
Since I don't take vitamins, I'm not very familiar with what is a normal dose of any of them.
