Why would my urine be green?

I“m taking Adrenal Support which contains quite a few B Vitamins, however that normally makes my urine yellow but now it’s green.
proper green!
Any ideas – could B vitamins make it green?
I“ve just come of a long haul flight if that could be a contribution?
I doubt I have a urine infection as green is the only symptom.
thanks for any help!
