Jarrow no longer makes NAC Sustain due to challenges to its use as a supplement by the FDA - since a high dose is a prescription drug, they argue that lower doses may not be sold as an unregulated supplement. The final decision is pending, and in the meantime, NAC can be a little harder to find. Also, inhaled NAC in ampules is a prescription medication.

NAC(ysteine)* is a mucolytic (thins mucus) when taken in dosages of 600-1200 mg daily. In high doses, it is used to detoxify liver and or kidneys after reaction to dyes used in procedures, or acetaminophen overdose.

Addition of milk thistle was done by a specific supplement maker, and promoted in their literature as a liver detoxifier, but is not necessarily beneficial to the lungs.

*There is another supplement sometimes referred to as NAC - it is N-acetyl-carnitine, and is not the same product, nor is it a mucolytic.
