You may not be familiar with N-Acetyl-l-Cysteine (NAC)‚ but it plays several essential roles in your overall health. It's derived from an amino acid called l-cysteine.

NAC may support the functioning of your respiratory system. Since it contains sulfur‚ N-Acetyl-l-Cysteine may thin the mucus by weakening the disulfide bonds. As a result‚ you can expel the mucus from your upper respiratory tract more easily; this can help you feel better‚ especially because mucus also traps bacteria and other particles.

In addition‚ NAC serves as a precursor to glutathione‚ meaning that it promotes increased production of the antioxidant; this may be especially helpful as you age. A N-Acetyl-l-Cysteine supplement may boost the level of glutathione present in your tissues‚ which can boost immunity and make you less likely to get sick. Glutathione supports the proper functioning of lymphocytes‚ which are immune system components. It can also promote heavy metal detoxification.

N-Acetyl-l-Cysteine (NAC) 900 mg by Pure Encapsulations is a convenient source of lung tissue‚ immune system‚ and detox support. It may have additional benefits: for example‚ NAC may help muscle tissues recover from the oxidative stress caused by exercise‚ allowing you to work out harder and more effectively.

One vegetarian capsule of this supplement provides 900 milligrams of free-form NAC to give you substantial assistance. It also contains fat-soluble vitamin C to further support absorption.

Take one or two capsules daily between meals. At the recommended dosage‚ each 120-capsule bottle of Pure Encapsulations' N-Acetyl-l-Cysteine (NAC) 900 mg should last for two to four months.

Pure Encapsulations seeks to formulate and manufacture high-quality‚ hypoallergenic dietary supplements. Quality control during the formulation and manufacturing process is paramount. All Pure Encapsulations products are made with the most bioavailable ingredients possible.

      Can't breathe without it.

      from Michigan on 11/17/2021
      I have ALS and rely on this to keep my lungs clear. It helps keep secretions clear and has kept me from needing non-invasive ventilation so far. THE MOST IMPORTANT SUPPLEMENT I TAKE.

    • Meds probably work, wouldn't buy again

      from Highlands ranch CO on 7/08/2021
      It took a lot longer than expected to arrive. Was much more expensive here than other stores. I saw it and bought it so I could just get started on this supplement and then it took a long time, I bought others and it finally came after I gave in and bought the product elsewhere

      Dietician recommended

      from Los Angeles, CA on 5/24/2021
      My dietician recommended I take this brand of NAC to help protect my liver. Based on my stool sample the labs showed that I my liver is not working properly. Instead of taking medication she recommended NAC as this could be less damaging to my liver.
