Timing
Separate by 3+ hours.
How it works
Activated charcoal non-specifically adsorbs organic molecules in the GI tract through physical binding to its porous surface.
This is not specific to NAC — charcoal will bind any oral supplement or medication. The adsorption is near-total for most organic compounds at typical charcoal doses. Ironic note: NAC is the clinical antidote for paracetamol poisoning, but must be given IV when charcoal has been administered.
What to do
Separate by at least three hours. Better yet, take charcoal well away from all supplements and medications. Its whole purpose is to bind things in the gut.
