Benefits of N-Acetyl Cysteine Supplement (NAC)

Nothing but active ingredients
Promotes antioxidant activity*
Respiratory aid*
Supports the body’s detoxification process*

N-acetyl cysteine (or NAC) is a derivative of the amino acid cysteine. NAC acts as a precursor to glutathione, a potent antioxidant compound made in the body. Glutathione’s strong antioxidant properties help prevent damage caused by oxidative stress and free radicals. Proper stores of glutathione support the immune system and help to neutralize toxins, including heavy metals.*

Trace minerals selenium and molybdenum provide extra support to glutathione’s many amazing properties.*

Taking NAC may be more beneficial than taking oral glutathione, as glutathione doesn’t fare well during digestion and isn’t well absorbed. Taking a glutathione precursor like NAC, however, allows for the production of intercellular glutathione, and NAC is readily absorbed during digestion.*

NAC has also been helpful in reducing symptoms of respiratory disorders, including coughing, wheezing and phlegm. NAC is particularly good at thinning thick phlegm. NAC binds to the sulfur in mucus and deteriorates the structure, making it easier to expel the mucus out the airways.* This feature makes NAC a great supplement to have around not just for cold and flu season, but for allergy season too.

Frequently Asked Questions
Q: What is the capsule size?
A: Capsule size 0.

Q; What type of capsule does this product come in?
A: This comes in a gelatin capsule. The gelatin is derived from bovine hide (beef skin).

Q: What is the difference between L-cysteine and N-acetyl cysteine?
A: L-cysteine can be made in the body or it can be derived from protein-rich foods. N-acetyl cysteine (NAC) can only be obtained from supplement or pharmaceutical drug form. NAC can be broken down into L-cysteine once inside the body. While L-cysteine plays important roles in building vital proteins in the body, NAC is known for being a precursor to glutathione, the body's master antioxidant.

Q: Why does this product smell rancid?
A: NAC naturally contains sulfur, which has an unpleasant smell. The odor is harmless to you and does not affect the product in any way. To keep our products as pure as possible, we don't add any manufacturing agents to mask the smell.

Q: The capsules I received have colored specks in them. Is that normal?
A: Yes, the appearance is normal. Our NAC capsules also contain selenium and molybdenum. The selenium raw material that we use is tan in color and the molybdenum raw material that we use is white with light blue specks. Combining all three raw materials together gives an overall appearance of off-white with tan/brown and blue/grey specks scattered throughout the capsule. To keep our products as pure as possible, we do not add any agents that mask the true color of the raw materials we use.

FAQs

What is Glutathione?

Glutathione is a potent antioxidant found in every cell of the human body, composed of three amino acids: cysteine, glutamine, and glycine. Often referred to as the "master antioxidant," it plays an essential role in protecting cells from oxidative stress and damage caused by free radicals. Glutathione is vital for detoxification processes, supports immune function, aids in the metabolism of fats and proteins, and even helps regenerate other antioxidants. Given its numerous functions, it is crucial for maintaining overall health, fighting inflammation, and preventing chronic diseases.

What is NAC (N-Acetyl Cysteine)?

N-acetyl cysteine (NAC) is a supplement derived from cysteine, a sulfur-containing amino acid that is crucial for the synthesis of glutathione. NAC is well-known for its ability to increase glutathione levels in the body, making it an essential supplement for supporting detoxification, enhancing immune system function, and promoting respiratory health. NAC has also shown promise in reducing oxidative stress, alleviating symptoms of chronic diseases, and supporting mental health by influencing neurotransmitter regulation in the brain.

How Do Glutathione and NAC Differ?

While both glutathione and NAC are integral to antioxidant defense in the body, their roles differ. Glutathione is a powerful antioxidant that directly neutralizes free radicals and helps protect cells from oxidative damage. It is involved in several biochemical processes, including detoxification, immune response, and cellular repair. On the other hand, NAC serves as a precursor to glutathione. When taken as a supplement, NAC boosts the production of glutathione in the body, indirectly enhancing the body’s ability to neutralize harmful free radicals and support overall detoxification. Essentially, NAC is a building block that supports the body's natural glutathione production.

What Are the Anti-Aging Benefits of Glutathione?

Glutathione is often considered a key player in anti-aging due to its role in reducing oxidative stress, which is one of the main factors in the aging process. Oxidative stress accelerates skin aging, causing wrinkles, fine lines, and loss of elasticity. Glutathione helps to neutralize free radicals, the unstable molecules that damage skin cells and cause premature aging. By protecting the skin and supporting healthy cellular function, glutathione can contribute to a more youthful appearance, reduce signs of aging, and promote overall skin health, making it a popular addition to skincare regimens.

How Does NAC Contribute to Detoxification?

NAC is particularly effective in enhancing the body's detoxification processes. One of its primary roles is boosting glutathione levels, which is essential for liver function and detoxification. Glutathione helps the liver break down and eliminate harmful toxins, heavy metals, and pollutants from the body. By increasing glutathione production, NAC supports the liver’s ability to detoxify more efficiently, thereby improving overall health and helping the body manage environmental toxins more effectively. Additionally, NAC’s antioxidant properties protect cells from oxidative damage during the detox process, contributing to better overall detoxification.

Can Glutathione Support Liver Cleansing?

Yes, glutathione is a crucial component in supporting liver health and function. The liver is the body’s primary detoxification organ, and glutathione plays a vital role in the liver’s ability to neutralize and eliminate toxins, free radicals, and waste products. It aids in the proper functioning of detoxification enzymes and helps break down harmful substances. Furthermore, glutathione protects liver cells from oxidative damage, which can result from the buildup of toxins. Supplementing with glutathione or supporting its production through NAC can help enhance liver cleansing and promote long-term liver health.

Are There Any Side Effects of Taking NAC or Glutathione?

Both NAC and glutathione are generally considered safe when taken in appropriate doses. However, some individuals may experience mild side effects, such as gastrointestinal discomfort, including bloating, nausea, or diarrhea. Rarely, allergic reactions may occur, leading to symptoms such as rashes, swelling, or difficulty breathing. It is important to consult a healthcare professional before starting any new supplement regimen, especially if you are pregnant, breastfeeding, or have pre-existing medical conditions. Your healthcare provider can help you determine the most suitable dosage and ensure the supplements are safe for your specific needs.

Can I Take NAC and Glutathione Together?

Yes, taking NAC and glutathione together can be highly beneficial. Since NAC serves as a precursor to glutathione, supplementing with both can help elevate glutathione levels more effectively, enhancing its antioxidant effects and supporting overall detoxification processes. This combination is often used to maximize the body’s natural ability to combat oxidative stress, improve immune function, and promote cellular repair. Many individuals who are looking to optimize their health, prevent aging, or support liver function find that taking both supplements together provides synergistic benefits.

How Should I Take NAC and Glutathione for Optimal Results?

To achieve optimal results, it is important to follow the recommended dosages for NAC and glutathione supplements, which can vary based on individual health needs. NAC is typically taken as a supplement in capsule or powder form, with the standard dosage ranging from 600 to 1,200 mg per day. Glutathione can be taken as a supplement, either in oral form or through intravenous administration (IV) for more immediate effects. Some food sources, such as whey protein, also support glutathione production naturally. For the best outcomes, it is advisable to consult a healthcare professional to determine the most appropriate dosage based on your specific health goals and needs.

What Foods Can Boost My Body’s Glutathione Levels?

Certain foods can naturally support and enhance your body’s glutathione production. Foods rich in sulfur-containing amino acids, such as garlic, onions, and cruciferous vegetables (broccoli, cauliflower, kale, and Brussels sprouts), are particularly beneficial for boosting glutathione levels. Additionally, foods high in vitamin C, such as citrus fruits (oranges, lemons, grapefruit) and strawberries, can help regenerate glutathione in the body. Including these foods in your diet can help promote the natural production of glutathione and support overall health, including improved immune function, detoxification, and cellular protection.
