NAC Dosage

NAC is generally safe if taking the recommended amount. Remember to start low and go slow. 

NAC dosage include 500 mg capsules, 600mg capsules and up to 1000mg capsules. These are generally safe dosages for the average adult.

Dosing for tylenol overdose should always be done by a medical professional, do not attempt to treat this at home for your safety.

Avoid taking nitroglycerin with NAC

Nitroglycerin is a potent vasodilator. Nitroglycerin is a medication prescribed for chest pain. NAC is also a vasodilator. If taken together, this could result in severe low blood pressure, lightheadedness, loss of consciousness.

Always talk to a medical professional before supplementing any medications. If you experience any major side effects, we advise you to go to a medical center immediately.
