View full detailsAbout N-Acetyl Cysteine
NAC, short for N-acetyl cysteine, is a stable form of the amino acid cysteine. Your body uses cysteine to make glutathione, one of its most important antioxidants. That is why NAC is a popular choice for antioxidant support, liver health and respiratory health.
This collection includes NAC capsules and tablets from 500 mg to 1,200 mg, plus NAC powders and combination formulas, from practitioner brands such as Thorne, Pure Encapsulations, Integrative Therapeutics, Klaire Labs, Xymogen, Protocol for Life Balance and NutriDyn.
How to Choose an NAC Supplement
- Standard NAC capsules: Usually 500 or 600 mg per capsule, which makes it easy to adjust your daily amount. NAC-600 by NutriDyn and NAC 600 mg by Pure Encapsulations are popular picks.
- High-potency NAC: 900 mg and 1,000 to 1,200 mg tablets mean fewer pills for people taking larger amounts.
- NAC powders: NAC + Glycine powder combines both glutathione building blocks in one scoop.
- Combination formulas: Pair NAC with milk thistle, alpha-lipoic acid or other nutrients for broader liver support.
NAC has a natural sulfur smell, which is normal and not a sign the product has gone bad. Many people take NAC with liver support or milk thistle formulas.
Frequently Asked Questions
What is NAC good for?
NAC supports glutathione production, antioxidant defenses, liver health and respiratory health. It is one of the most widely used amino acid supplements in practitioner offices.
How much NAC should I take?
Most labels provide 600 to 1,200 mg per day. Some people split the amount into two doses. Follow the label or your practitioner's guidance.
Is NAC the same as glutathione?
No. NAC is a building block your body uses to make its own glutathione. Some people take NAC, some take glutathione directly, and some take both.
Should I take NAC with food?
NAC can be taken with or without food. Taking it with a meal can help if you have a sensitive stomach.
