It is popular due to its cysteine residues and the role it has on glutathione maintenance and metabolism. Relative to glutathione availability, one of the most important considerations has been to properly maintain the availability of cysteine in the blood as that is known to be the rate-limiting substrate for glutathione resynthesis.

IMPORTANCE OF NAC The acetyl group in NAC makes cysteine more water-soluble, and functions to speed absorption and distribution on orally ingested cysteine. The acetyl group reduces the reactivity of the thiol (-SH), making NAC less toxic and less susceptible to oxidation than cysteine. Hyperproduction of oxygen free radicals and the weakening of natural scavenging mechanisms have been implicated as contributors to cell, tissue or organ damage. While your body has natural antioxidant defense mechanisms, too many free radicals can overwhelm the body and deplete the natural stores. NAC exhibits direct as well as indirect antioxidant properties. Its direct antioxidant effect arises due to a thiol group interacting with free radicals. It indirect antioxidant effect is related to its role as a glutathione precursor, resulting in an increase of intracellular concentration. WHAT IS GLUTATHIONE? Glutathione accounts for a huge percentage of your total body antioxidant capacity. Glutathione is a tripeptide composed of 3 amino acids: cysteine, glycine and glutamic acid. Often termed as the master antioxidant, glutathione boosts the utilization and recycling of other antioxidants, namely vitamin C, E, alpha-lipoic acid and CoQ10. Maintaining adequate glutathione levels is one of the most important keys in maintaining proper cellular function, immune health and in slowing oxidative damage. HOW DOES NAC SERVE FOR GLUTATHIONE SYNTHESIS? After deacetylation in the intestines and liver, NAC yields cysteine as one of its metabolites. This circulating cysteine may enter renal cells and serve as a precursor for glutathione production. Taking NAC as a dietary supplement helps boost tissue levels of glutathione. WHO WOULD HAVE LOW GLUTATHIONE LEVELS? Elderly people People with injuries or inflammatory bowel disease Overtrained athletes People with alcoholism Those consuming processed foods/prone to stress and environmental toxins, who suffer from lack of sleep are typically associated with low levels of glutathione HOW TO CONSUME THE SUPPLEMENT It is recommended to consume one serving of the dietary supplement daily after meal. NAC supplement is best proven to sustain the body’s glutathione stores. Glutathione is concentrated in all human cells, detoxification enzymes in the liver, kidneys, liver use glutathione to bond with toxins and thereby make them able for elimination. NAC supports a diverse collection of detox enzymes that dispose of toxins and support effective detoxification. BOOSTS IMMUNITY Compromised immunity is an important reason to acquire an infection. Supplementing with super antioxidant like NAC produces a direct positive effect on immunity. Depletion of both glutathione and NAC leads to increased oxidative stress which plays a vital role in the first line immune response to pathogens. Cysteine supply is significant for immune health because small variations strongly influence lymphocytes and other immune cells. HELPS ATTENUATE MUCLE FATIGUE It has been widely reported that an exercise bout consisting of muscle contractions can result in substantial oxidative damage and onset of inflammation. In response to the muscle damage, circulating levels of hydroxyl radicals, lactate dehydrogenase and creatine kinase, markers of protein breakdown get elevated after exercise. NAC is an effective scavenger of free radicals as well as a major contributor maintenance of the cellular glutathione status in muscle cells and thus prevent muscle fatigue. SUPPORTS BRAIN HEALTH Of all the tissues in the body, brain is particularly vulnerable to oxidative stress as it uses a lot of oxygen. The defense against oxidative stress helps keep inflammation under control. NAC may support healthy neurotransmission through detox and antioxidant activities. As a potent antioxidant, NAC has shown to neutralize free radicals before they may cause damage in cells. Its anti-inflammatory properties that has been linked to mental health disorders. ## Features - N-Acetyl L-Cysteine ,Free Radical Protection - Maintains Cellular Health - Normal Immune System Function,Amino Acid - Precursor to Glutathione, Powerful Antioxidant - Dietary Supplement,GMP Quality Assured ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B073P7YB63 | | Age Range Description | Adult | | Best Sellers Rank | #43,776 in Health & Personal Care ( See Top 100 in Health & Personal Care ) #29 in N-Acetyl-Cysteine | | Brand | Zenith Nutrition | | Container Type | Canister | | Country of Origin | India | | Customer Reviews | 4.2 out of 5 stars 240 Reviews | | Diet Type | Vegetarian | | Dosage Form | Capsule | | Flavor | Unflavoured | | Flavour | Unflavoured | | Item Form | Capsule | | Item Weight | 0.07 Kilograms | | Manufacturer | Zenith Nutrition | | Manufacturer Part Number | 4400291332 | | Material Features | No Artificial Flavours | | Net Quantity | 60 Count | | Number of Items | 1 | | Primary Supplement Type | sulfur | | Product Benefits | LUNGS PROTECTION | | Special Ingredients | Amino Acid | | Unit Count | 60 Count | ## Product Details - **Age Range (Description):** Adult - **Brand:** Zenith Nutrition - **Diet Type:** Vegetarian - **Flavour:** Unflavoured - **Item Form:** Capsule - **Item Weight:** 0.07 Kilograms - **Net Quantity:** 60 Count - **Primary Supplement Type:** sulfur - **Product Benefits:** LUNGS PROTECTION - **Special Ingredients:** Amino Acid ## Images ![Zenith Nutrition Nac (N-Acetyl L-Cysteine) Liver & Antioxidant Support 500Mg - 60 Veg Capsules - Image 1](https://m.media-amazon.com/images/I/71NobewRU5L.jpg) ![Zenith Nutrition Nac (N-Acetyl L-Cysteine) Liver & Antioxidant Support 500Mg - 60 Veg Capsules - Image 2](https://m.media-amazon.com/images/I/719woKtvRrL.jpg) ![Zenith Nutrition Nac (N-Acetyl L-Cysteine) Liver & Antioxidant Support 500Mg - 60 Veg Capsules - Image 3](https://m.media-amazon.com/images/I/71qRgzZY4qL.jpg) ![Zenith Nutrition Nac (N-Acetyl L-Cysteine) Liver & Antioxidant Support 500Mg - 60 Veg Capsules - Image 4](https://m.media-amazon.com/images/I/61JC-yjcoSL.jpg) ![Zenith Nutrition Nac (N-Acetyl L-Cysteine) Liver & Antioxidant Support 500Mg - 60 Veg Capsules - Image 5](https://m.media-amazon.com/images/I/61WjmABLaWL.jpg) ## Questions & Answers **Q: How many tablets are there?** A: its a 60 capsules bottle.. **Q: What is the source of the cysteine used?..
