Nutrigel - worth adding to hypo toolbox?

Freya has an almost 2hr drive to the vet tomorrow just so we can learn
how to check her BG.
We have a tube of Nutrigel - does anyone know the carb content & would
it be worth us taking it with us just in case…?
We can also take a bowl & a sachet of ‘normal’ cat food, but if Nutrigel
will work faster, I’m just wondering if this is worth considering as it may be
easier to administer in a moving car.
Thoughts, please?
