Antioxidant and Glutathione Precursor!

N-Acetyl-L-Cysteine (NAC) contains 750 mg of NAC‚ which is an altered form of the amino acid l-cysteine‚ per capsule. NAC enhances glutathione production and has been shown to support healthy lung function.

A review of 39 clinical trails of N-Acetyl cysteine found that 400 to 600mg per day was a safe and effective treatment for chronic bronchitis. NAC supplementation was found to reduce the number of aggravations of the illness in almost 50% of people taking the supplement‚ compared with only 31% of those taking placebo. Smokers have also been found to benefit from taking NAC.

In addition to helping break up mucus‚ NAC may reduce the elevated bacterial counts that are often seen in the lungs of smokers with chronic bronchitis. In another double-blind study‚ people with chronic bronchitis who took NAC showed an improved ability to expectorate and a reduction in cough severity. These benefits may result from NAC's capacity to reduce the viscosity (thickness) of sputum.

      Hurry - Rumors of banning these types

      from Dirty Jersey Gym on 7/27/2021
      Great product - I love this high dose. In these times it is important to bump up lung health. This product will enhance natural glutathione production in your body which is better than just buying a synthesized gluthathione product.


      Powerful, effective - GREAT price point
