How to Take It
Best taken in the morning
Many people prefer B-vitamins earlier in the day; take with food to avoid nausea.
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.
On the label
Take 1 capsule daily, or as directed by your healthcare professional.
General guidance based on the ingredients, not a substitute for the label or your doctor.
