Hi Ryan ,
Welcome to HealthcareMagic.
Jack3d has Maltodextrin , caffeine ,Magnesium
as crucial components that can affect you.Caffeine can increase the general activity of your brain and thus can make you prone to seizure
. Rest two would actually benefit the growth of the brain.
Oxcarbezine acts on Sodium channels and regulates the brain activity.There is not much evidence of its effects on Magnesium.In a well hydrated state there are less chances of hypermagnesemia
I advise you to switch to non caffeine supplement .
Take care .
