NAC (N-Acetyl Cysteine) - 600 mg, 100 vegetarian capsules by ProHealth

An Effective Detoxifying Nutrient and Antioxidant

  • Powerful free radical scavenger and detoxifier
  • Enhance immune system function with Selenium and Molybdenum
  • Helps boost glutathione production


N-Acetyl Cysteine (NAC) is a potent antioxidant and cell detoxifier. It is derived from the amino acid L-Cysteine, and plays an important role in the production of glutathione, the body's primary antioxidant that's crucial in the fight to neutralize free radicals and to detoxify harmful agents from the body*.

The primary function of N-Acetyl Cysteine is in the production of glutathione. Glutathione is a small protein found inside cells that plays an important role in the body’s antioxidant defense system. N-Acetyl Cysteine is quickly metabolized into glutathione once it enters the body. Glutathione then functions as a powerful antioxidant and cell detoxifier.

As an antioxidant, glutathione effectively scavenges free radicals, neutralizing their harmful effects upon cells. As a detoxifier, glutathione can alter chemicals so that they become less harmful. Glutathione enhances the immune system by aiding the transport of important nutrients to immune cells called lymphocytes and phagocytes, as well as helping to strengthen cell membranes. Glutathione's other benefits include promoting the manufacture of new muscle mass and maintenance of RNA and DNA.

NAC for mitochondrial health!

Been on this NAC product for a few months now and I’m satisfied with its purity like everything I get from PHL.

Trusted brand

I was advised by my doctor to take NAC, and he recommended ordering from ProHealth. I like that the capsules are vegetarian and that this is a trusted company.

Good supplement

My first month into this so will be improving health as months go by.

Interacted poorly with my body

For whatever reason, and I think it was this supplement, I lost my appetite while taking it. Like, normal everything except not feeling hungry ever when I normally always do. I am also taking other drugs so it could have been an interaction or something else. Unknown. But that's why I'm not using it anymore.
