Much has been made of Red Bull's seemingly excessive B6 vitamin
count. However, a quick bit of math renders the following results:
At 250% of your daily B6 intake, Red Bull contains 2.5 mg of B6. The FDA has set the safe intake for B6 at 100mg/day. Studies indicate that damage to nerves in the arms and legs occurs before the 500 mg mark.
So, no reason to panic! You'd have to consume 40 cans of Red Bull a day to meet the FDA upper limit. And if you're doing that, you've got more problems than B6.
