NAC (N-Acetyl Cysteine), ranked by real cost

Look for NAC, N-Acetyl Cysteine, or N-Acetyl L-Cysteine on the Supplement Facts panel and confirm the amount per serving. Labels reviewed for this update included straightforward 600 mg capsules, 1 g tablets, 600 mg powder servings, and multi-ingredient gummy or liver-support products with much lower NAC amounts.

Powder is often the cheapest NAC format because large pouches can contain hundreds or thousands of 600 mg servings. Capsules and tablets trade some value for convenience, while gummies, hydrogen tablets, and liver or detox blends can cost much more for the same NAC target.

Do not pay for a long detox, liver, immune, or antioxidant formula as if every ingredient were more NAC. Selenium, milk thistle, vitamins, hydrogen-tablet positioning, and other add-ons may matter to a shopper, but the cost ranking counts the labeled NAC amount first.

NAC has stronger evidence than many supplement categories, especially around respiratory mucus clearance, liver protection, and glutathione support. TrueServing compares labeled NAC cost at the reference dose; it does not replace medical guidance or validate broad detox claims.
