What is NAC (N-Acetyl L-Cysteine)?

NAC is a precursor to Glutathione, which is a powerful antioxidant. This is a better option than supplementing with just glutathione since glutathione alone is not absorbed well in the body.


N-Acetyl L-Cysteine (NAC) Benefits

NAC is a great supplement to add to any daily stack. It has nootropic properties and functions as an anxiolytic. This supplement also protects the liver, stomach, and kidneys. NAC also provides several other benefits:


  • Protects and promotes healing of the respiratory system[1]
  • Reduces nicotine dependence[2]
  • Reduces withdrawal symptoms[3]
  • Defends the body and brain from oxidative damage[4]
  • Promotes positive mood[5]


NAC Supplement Side Effects

Though rare when taken as directed, some individuals supplementing with N-Acetyl L-Cysteine reported headache, drowsiness, nausea, and constipation.


NAC Dosage

Take one capsules (600mg) once daily.

It is suggested that N-Acetyl L-Cysteine be taken in serving sizes of 1 capsule (600mg) up to three times daily. It is also recommended that, if possible, the supplement be taken with Vitamin B6, Vitamin E and Selenium in order to enhance the antioxidant properties of it. Vitamin C supplements, if taken in conjunction with NAC, can also assist the antioxidant abilities while increasing the amount of glutathione being produced by the body.
