I began taking a multivitamin for the first time recently. This multivitamin is called " GNC MEGA MEN"
It contains massive doses of some of the B vitamins, and I'm wondering if this can be causing my insomnia. I have been working my butt off in the gym, not consuming caffiene or other stimulants, and yet for the last 5 days I have only been able to sleep 4 hours. I'm waking up bleary eyed and becoming irritated with people, so please give me some advice.
Here is my concern :
Vitamin B-1 = 50mg = 3333%
Vitamin B-2 = 50mg = 2941%
Vitamin b-6 = 50mg = 2500%
Is that too much B vitamins? Also, there is 900 mg of both Lutein and Lycopene. If the B vitamins aren't the cause, could the Lutein or Lycopene be the cause?
