What is NAC used for?

N-acetyl-L-cysteine is a precursor to glutathione. In the body, glutathione is a powerful antioxidant which helps protect cells from oxidative stress. NAC supplements are used for immune health support.

How does NAC support immune health?

Studied for its immune health benefits, N-acetyl-L-cysteine defends against insults from foreign compounds. N-acetyl-L-cysteine supports healthy respiratory function as well as bronchial health.

What does NAC do for your liver?

N-acetyl-L-cysteine has powerful antioxidant effects, helping to protect cells from free radicals.

Is it safe to take NAC daily?

It is generally OK to take N-Acetyl-L-Cysteine (NAC) every day. Consult your health care practitioner if you have concerns about adding NAC to your supplement regimen.

When to take NAC, morning or night?

There is no specific time to take NAC optimally, although we recommend taking 1-3 times a day, depending on dosage. If you have sensitive digestion, you can take NAC with meals.
