Cold and flu season is upon us 🤧

Got a tickle in the throat? Just pop some vitamin C, right?

A beneficial move for most, but for those taking certain ADHD medications, this could be a cause for concern, depending on when it’s taken.

Vitamin C

The most popular ADHD drugs are classified as stimulants. These stimulants act by increasing dopamine and norepinephrine levels in the brain. This is what tames the ADHD symptoms and allows for more focus, motivation and less hyperactivity and racing thoughts.

So as you can imagine, it’s generally good for ADHD meds to be able to do their job so that people can function throughout the day and whatnot.

Right?

What you may or may not know is that a certain class of stimulants named amphetamines can be inactivated when taken with vitamin C.

Amphetamines are a certain class of stimulants that can be inactivated when taken with Vitamin C.

Brand names of common amphetamines:

  • Adderall
  • Adderall XL
  • Dyanavel XR
  • Vyvanse

When Vitamin C and amphetamines are in the stomach together, this causes a chemical reaction that changes the form of the amphetamine so that won’t be able to be absorbed in the bloodstream.

Rendering it ineffective.

Therefore, most doctors advise against ingesting vitamin C for an hour before and after taking an ADHD medicine that contains an amphetamine.
