Most research uses 1.2g daily. Below 0.6g, you're probably wasting money. Above 2.4g, no extra benefit. The curve plateaus. Safe upper limit ~ 3.0g.
NAC is converted to cysteine, which is then used to produce glutathione. Glutathione is a powerful antioxidant that helps protect cells from damage.
NAC is well-researched, but the evidence for its immune benefits in healthy individuals at typical supplement doses is moderate. Its primary benefit is as a glutathione precursor, supporting antioxidant defenses, which indirectly supports immune function. Evidence is stronger for specific conditions.
L-cysteine, the amino acid NAC is made from, is found in high-protein foods like chicken, turkey, eggs, and dairy.
