## Overview

NOW Sports NAC 1000 mg delivers a potent dose of N-acetyl cysteine, a sulfur-containing amino acid that supports glutathione production for powerful free radical protection, immune system balance, and liver detoxification. Certified clean and manufactured under strict GMP and ISO/IEC standards, this supplement is designed for professionals seeking reliable, high-quality cellular and cognitive health support.

## Description

Immune System Support* Supports Liver Health* N-acetyl cysteine (NAC) is a stable form of the non-essential amino acid cysteine. It is a sulfur-containing amino acid that acts as a stabilizer for the formation of protein structures, and promotes the formation of glutathione.* Glutathione is a powerful free radical scavenging compound that also helps to maintain normal, balanced immune system function.* In addition, NAC can help to support healthy brain and neuronal tissues.* Natural color variation may occur in this product.

Review: Reputable brand - Good quality NAC supplement from a trusted brand. The 1,000 mg dose is effective and convenient, especially for antioxidant and liver support. Tablets are solid and a bit large, but manageable with water. I noticed improved overall clarity and respiratory support with consistent use. No stomach upset or negative side effects. Great value for the quantity.
Review: Very good product - People don’t know that NAC ingredients is basically Sulfur and don’t understand why smells like sulfur, they’re big but I don’t have problems with big sizes, NAC activates Glutathione so the liver does his job detoxing the body Very good product 100% recommended

## Questions & Answers

**Q: In what country are these manufactured?**
A: It may be encapsulated in the US, but I wrote to NOW and the raw material comes from China.  So, to say it's "made in the USA" is a bit misleading, if you asked me.

**Q: Is n-acetyl-cysteine the same thing as n-acetyl-l-cysteine, note the "l"?**
A: N-acetyl-cysteine, N-acetylcysteine, N-acetyl cysteine, and N-acetyl-L-cysteine are all designations for the same compound, which is abbreviated as NAC. NAC is a precursor to the amino acid cysteine, which ultimately plays two key metabolic roles. Lovely stuff.

**Q: Is this product peanut free?**
A: This product is nut-free and is not manufactured with wheat, gluten, soy, milk, egg, fish, shellfish or tree nut ingredients. Produced in a GMP facility that processes other ingredients containing these allergens.

**Q: does this help with carb and sugar cravings?**
A: I bought it to help with sinus congestion.  It does work for that. Not sure about carb & sugar cravings.
