Vitamart's Take
This is a high-dose, straightforward NAC: 900 mg per capsule with nothing else in the active list. NAC is best known as a glutathione precursor, and Designs for Health highlights it for detoxification, lung health and recovery after workouts, as well as protection against normal exposure to heavy metals. The Canadian label carries the claim for relief of chronic bronchitis symptoms. The dose is 2 capsules a day with meals, and the label limits use to 24 weeks.
How NAC 900mg Compares
NAC vs. liposomal glutathione
NAC gives your body the building block to make its own glutathione. Designs for Health Liposomal Glutathione delivers glutathione itself in a liposomal liquid.
900 mg vs. lower-dose NAC
Many NAC products use lower-dose capsules. At 900 mg per capsule, this one reaches the label dose in just 2 capsules a day.
NAC vs. liver formulas
Multi-ingredient liver formulas such as Designs for Health LV-GB Complex combine several herbs and nutrients. NAC is a single, focused ingredient.
