Thorne Research NAC - N-Acetylcysteine

Amino acids are often referred to as the “building blocks of life”. There’s a good reason! Your body combines amino acids to form proteins. They provide energy for your body. They’re essential for growth and development. Plus, they help build even more protein!

So, it’s no surprise that supplementing your daily diet with additional amino acid support is beneficial! While your body produces amino acids on its own, adding a dietary aid like Thorne Research NAC to your wellness routine allows you to target areas of your body that you’d like to show some extra love.

N-acetylcysteine, or NAC for short, is a sulfur-containing amino acid. It’s also a powerful antioxidant. This means it helps your body defend against oxidative stress by keeping free radicals in check!

As the name suggests, free radicals are just that—free and radical. They’re unpredictable. They can also be destructive if they overwhelm your system. Antioxidants like NAC help balance free radical levels.* This helps your immune system function at its best.

As if NAC weren’t impressive enough on its own, it’s also used to make glutathione—known as the antioxidant of all antioxidants! Glutathione is key for healthy kidney and liver function—and your body’s detoxification process.

Your kidneys and liver aren’t the only organs NAC supports, though. It also lends a helping hand to your lungs. NAC works to thin mucus membranes in your lung tissue. This can help improve lung function and even alleviate some lung disease symptoms.*

Wonder what else this amino acid can do? The list goes on! NAC also:

  • Supports reproductive health in women*

  • Promotes healthy brain function and cognitive health*

  • Aids your body’s ability to balance insulin levels*

  • Helps with athletic performance and recovery after exercise*


NAC is a powerful amino acid that supports several essential body functions. For additional amino acid support, try Solgar BCAA Plus (Branched Chain Amino Acids). But don’t forget the magnesium! Pure Encapsulations Magnesium Citrate helps your body absorb amino acids, so your body can make the most of those powerful nutrients.
