NOW Foods - NAC N-Acetyl Cysteine 600 mg. - 250 Vegetarian Capsules

A Precursor Pill to Stimulate the Body’s Production of Antioxidants
The body has the ability to produce natural antioxidants in the form of glutathione. This antioxidant is formed within the liver. However, production of such antioxidant is influenced not only by age but also the overall health of an individual. This means that if an individual is already in his or her advanced stage and has compromised health, the body’s production of glutathione slows down to a trickle. While antioxidants can be sourced from food, it is still crucial to simulate the body’s ability to produce its own antioxidant. This is where the NOW Foods–NAC N-Acetyl Cysteine Capsules come in.

    Pushes the Body to Produce Its Own Antioxidant
    N-Acetyl Cysteine is a type of stable-form amino acid L-Cysteine. This amino acid contains sulfur that serves as a stabilizer for the formation of protein structure. The formation of unnecessary protein structures is indicative of a tumor. Several studies suggest that N-Acetyl Cysteine can help prevent polyp formation and are beneficial to people who are at risk of developing colon problemsr. But most importantly, it is also used to protect the liver and to coax it to produce more glutathione – the body’s natural antioxidant.

    Helps in The Body’s Detoxification Process
    The high antioxidant properties of N-acetyl cysteine helps with the body’s natural detoxification processes. It helps prevent side effects of drugs as well as different types of environmental toxins. This is the reason why it may be given to people who suffer from drug overdose particularly acetaminophen. It may also benefit people who are suffering from diminished kidney and liver function due to its anti-inflammatory effects. It also does not present any severe side effects on people with compromised liver and kidney function.

    May Help Improve Different Types of Conditions
    Scientific evidence suggests that N-acetyl cysteine may help improve different types of conditions and diseases. People who suffer from infertility, cystic fibrosis, flu, liver disease, angina, high cholesterol, and certain eye diseases may see improvement upon regular intake of this supplement. Optimal doses of N-acetyl cysteine has not yet been set yet anecdotal references noted that intake of one capsule twice daily can bring positive results to the body. For better results, it may also be taken in combination of alpha lipoic acid and other antioxidants.

    N-Acetyl Cysteine and More
    Each serving of this supplement contains 600 milligrams of N-acetyl cysteine to push the body to start producing glutathione. Aside from glutathione, it also contains 50 micrograms of molybdenum and 25 micrograms of selenium. These are important trace elements that are necessary for the healthy physiological functions of the body. For instance, molybdenum is important in removing toxins from the metabolism of sulfur-containing compounds. Selenium helps the body manufacture special proteins and antioxidant enzymes thus they play role in preventing cellular damage.

    Manufactured Under High Standards
    All products produced by NOW Foods are manufactured following high-quality standards. All processes follow Good Manufacturing Practices such that all operating procedures, employee training, and product specifications meet with industry standards. The products are tested to ensure that they do not contain contaminants and are acceptable in terms of organoleptic evaluation. The company has its own in-house laboratories to ensure the quality standard of its products. Thus, all products are tested safe and effective before delivered to market shelves.

    NOW Foods N-Acetyl Cysteine (NAC) is a stable form of the non-essential amino acid L-Cysteine. NOW Foods NAC N-Acetyl Cysteine is a sulfur-containing amino acid that acts as a stabilizer for the formation of protein structures, and is also necessary for the formation of Glutathione. Molybdenum and Selenium in Now Foods NAC N-Acetyl Cysteine are essential trace minerals that facilitate the production of several important enzymes.

    NOW's Mission
    The NOW mission is - To provide value in products and services that empower people to lead healthier lives. NOW Foods is an award-winning and highly respected manufacturer of vitamins, minerals, dietary supplements and natural foods.

    In 1948, with the natural food and supplement industry in its infancy, entrepreneur Paul Richard paid $900 for the purchase of Fearn Soya Foods—a Chicago based manufacturer of grain and legume-based products. This began a six-decade legacy of providing health-seeking consumers with high-quality, affordable nutrition products.

    History of NOW
    In 1968, NOW Foods was founded under the belief that good health was not a luxury available only to the wealthy. For the past forty years, NOW has made it their life's work to offer health food and nutritional supplements of the highest quality, at prices that are fair and affordable to all those who seek them. Today, NOW Foods is one of the top-selling brands in health foods stores, an award-winning manufacturer, a respected advocate of the natural product industry, and a leader in the fields of nutritional science and methods development.

Nurturing this competency of value drives NOW's ability to provide high quality products at the very best prices.
    • Natural is Better - NOW is convinced that natural products are better than their synthetic counterparts and produce better results in human health. Therefore, wherever possible, NOW strives to provide products that contain natural ingredients because they are better for their customers.

    This product has been a life saver. I have more energy and can actually tolerate wine now and then since using this. Anyone having issues with liver (mine is from a bike injury) should really take this for support in detoxification. Even the little "sun spots" on my cheeks have faded/disappeared since using this.

    I started giving my mom these vitamins when she was fighting cancer. I feel that it helped her live longer and stronger. I now take them because I am a cancer survivor and feel that they help me as well.
