What is the cheapest NAC per dose?+
Premier Research Labs Premier NAC - NAC Supplement N-Acetyl Cysteine — $0.007 per serving ($0.39 for 60 servings), the lowest cost-per-dose nac in our Amazon US catalog as of June 2026.
What is the typical cost per dose for NAC?+
About $0.12 per serving across 38 tracked nac products, ranging from $0.003 for the best deals to $0.20 for premium options.
Is the cheapest NAC the best one to buy?+
Not always. The cheapest is sometimes cheaper because of the form — magnesium oxide costs less than glycinate per gram but absorbs at a fraction of the rate. Weigh cost-per-dose against form bioavailability and third-party testing, not price alone.
