    Reduce the Damage of Oxidative Stress

    Glutathione could be the most important of all antioxidants, which help us protect against oxidative damage from pollutants and toxins.

    N-acetyl-L-cysteine - or NAC - is a form of an amino acid that acts as a crucial precursor to glutathione while also providing its own antioxidant activity.

    Allergy Research offers its NAC supplement as an ideal alternative to L-cysteine alone. When taken orally, NAC is converted into L-cysteine after your body absorbs it. NAC could be preferable because it is considered more stable than L-cysteine, which can degrade before it is used in the body.

    There are many potential benefits to NAC supplementation including:

    • Reducing excess mucus from lung conditions
    • Heart health support
    • Kidney health support
    • Reducing homocysteine levels
    • Reducing chest pain related to angina
    • Reducing flu-like symptoms

    Get important antioxidant protection that your body can use. Order NAC from Allergy Research now.

    I Have Taken This Product for Many Years

    NAC is a precursor to cysteine, and my California doctor recommended this supplement to me. Cysteine is necessary to the production of glutathione, a major antioxidant.

    Indispensable for Cystic Fibrosis

    Indispensable for Cystic Fibrosis patients like myself. The difference is clearly noticeable when I do not use this, in terms of how loose or how sticky phlegm is in the lungs. I also know CF puts quite the oxidant stress on the body, and NAC is also a boon to help my glutathione production...I feel better in general when I have NAC on a daily basis. I take a tab about 3-4 times a day, usually with meals so I remember. The efficacy of these tablets are as good as others I have used.

    Doctor Recommended Supplement

    This is a precursor to glutathione, which helps the body get rid of toxins. Since I have Multiple Chemical Sensitivity, I'm sure to have difficulties processing toxins. This was recommended by my doctor in California, and I'm still taking it, even though I left there almost 5 years ago.
