According to scientific research, oral N-acetylcysteine (NAC) has a notably low bioavailability, meaning the body does not absorb it well, with estimates ranging from 6-10%. This fact is critical when deciding whether you should take NAC with a meal or empty stomach to maximize its effectiveness and minimize potential side effects.

Research shows that oral NAC has low bioavailability, with less than 10% of the active compound reaching systemic circulation. To overcome this challenge, understanding what is the best way to take NAC is crucial for maximizing its health benefits, from boosting glutathione to supporting liver and lung health.

Experts and supplement providers generally recommend waiting at least 30 minutes after taking NAC to eat in order to ensure optimal absorption. Taking N-acetylcysteine on an empty stomach helps prevent competition with other amino acids, maximizing its effectiveness for raising glutathione levels.

Approximately 50% of Americans use dietary supplements regularly, but a common question for many users is how to properly time them with meals. So, can NAC supplements be taken with food? While NAC is best absorbed on an empty stomach, taking it with food can help prevent potential gastrointestinal side effects.
