How to Take It
Take it anytime
Take with food and split doses above 500 mg — absorption drops at higher single doses.
With food
NAC does better on an empty stomach, but something else in this bottle needs food. Taking the whole product with a meal is the better trade — an upset stomach is why most people stop.
Keep it away from high-oxalate foods like spinach
Space it a couple of hours from Iron, Magnesium and Zinc
On the label
Take two to four capsules daily, or as directed by your healthcare professional. Consult your healthcare professional prior to use.
General guidance based on the ingredients, not a substitute for the label or your doctor.
