Questions & answers

Frequently asked questions

What is NAC, and what does it support?

NAC (N-acetylcysteine) is a form of the amino acid cysteine that your body uses to make glutathione, one of its most important antioxidants. Daily NAC helps protect cells from oxidative stress and supports healthy brain, immune, liver, and respiratory function.*

How do I take it?

Take one capsule two to three times daily with water, as directed on the label. Taking it with food can help if you have a sensitive stomach. One bottle of 90 capsules lasts 30 to 45 days, depending on your daily amount.

Why does it smell like sulfur?

The smell comes naturally from the sulfur in cysteine and is normal for genuine NAC. Keep the lid tightly closed and store the bottle somewhere cool and dry.

Are there side effects?

Most people tolerate NAC well. Some notice mild nausea or digestive upset, and taking it with food usually helps. Stop use and talk to your healthcare provider if discomfort continues.

Can I take it with medications?

Talk to your doctor before use if you take nitroglycerin or other nitrate medications, blood pressure medications, or blood thinners, or if you have asthma. Also check with your healthcare provider if you’re pregnant, nursing, or managing a health condition.
