Discover the Health Benefits of NAC+ Glycine

Glutathione (GSH) is the most abundant antioxidant in the body and is composed of the amino acids cysteine, glutamic acid, and glycine. Because the production of GSH is generally limited by the body’s supply of cysteine, replenishing cysteine levels supports glutathione synthesis. N-Acetyl Cysteine (NAC) plays a role in the production of cysteine; therefore, cysteine and NAC are critical components supporting the body’s ability to detoxify and reduce tissue damage caused by free radicals. MaxLiving NAC + Glycine combines the much-needed doses of NAC and glycine to promote the synthesis of GHS, the body’s natural anti-inflammatory.

Product Information

One of the best defenses against free radicals is a healthy glutathione level, an amino acid that scavenges for free radicals and stops them in their tracks. Naturally boost your body’s ability to fight against oxidative stress, recover from exercise, and repair muscle with glycine, the main component of collagen and N-Acetyl Cysteine (NAC), to replenish the body’s amount of the antioxidant glutathione. MaxLiving NAC + Glycine contains two critical components in the synthesis of glutathione, one of the body’s most powerful amino acids that acts as an anti-inflammatory, reduces tissue damage caused by oxidative stress, and supports muscle growth and strength.

NAC + Glycine vs. Competitors
NAC + Glycine
MaxLiving NAC + Glycine is scientifically formulated to provide therapeutic levels of the key elements, N-Acetyl Cysteine and glycine, needed for optimal glutathione production. Conventional supplements generally only contain N-Acetyl Cysteine or glycine, not both, which reduces the quality and performance of the supplement.
MaxLiving NAC + Glycine is blended from synthetic compounds, which undergo raw ingredient testing, which eliminates contamination, and is manufactured in a climate controlled, HEPA filtered facility holding the following certifications: USP, QAI, NSF, and cGMP. Conventional N-Acetyl Cysteine and/or glycine supplements may be contaminated with other elements or chemicals, which may reduce the potency and purity of the product.
As a pure supplement, MaxLiving NAC + Glycine is free of GMOs, sugar, salt, dairy, eggs, peanuts, tree nuts, fish, shellfish, yeast, wheat, gluten, soy, preservatives, artificial colors, flavors, sweeteners, and toxins so you can be confident no harmful substances are being carried into sensitive areas of the body. It is ideal for individuals who are sensitive to common allergens and suitable for vegetarians and vegans. Many other N-Acetyl Cysteine and/or glycine formulas contain added fillers, preservatives, artificial sweeteners, and/or surplus nutrients that are not needed to increase cost.

How to Use NAC + Glycine

As a dietary supplement, adults mix one scoop with 10–16 oz of water or juice once in the morning and once in the evening, or as directed by your qualified healthcare practitioner.


Scientific Support

Glutathione (GSH), is the most abundant antioxidant in the body synthesized by three essential amino acids: cysteine, glutamic acid, and glycine. Glutathione, as a powerful antioxidant, is one of the body’s most important components acting as a free radical scavenger and facilitating detoxification.

Although glycine and L-glutamic acid are generally abundant in the human diet, the synthesis of glutathione is limited by the body’s supply of cysteine. Increases in the body’s supply of cysteine, increases the production of glutathione.

N-Acetyl Cysteine (NAC) is found in minute quantities in the blood and is a precursor to the amino acid, cysteine. Due to their role in glutathione production, cysteine and NAC play a crucial role in the body’s ability to detoxify.

  • Oxygen is required for cellular metabolism, and any sudden increase in oxygen in the body leads to the production of free radicals—or reactive oxygen species (ROS). During times of exercise or aerobic energy metabolism, there is an increase of the production ROS, which results in muscle or tissue damage.
  • Cysteine depletion occurs in aerobic animals and occurs more during times of oxidative stress because of the way human cells regulate oxidative stress. Scientists claim that cysteine depletion affects the majority of the body’s antioxidant defenses, and note the link between cysteine deficiency and numerous diseases, such as Huntington’s disease, Alzheimer’s disease, arthritis, cardiovascular disease, AIDS, and certain cancers.
  • Supplementation with NAC improves the body’s ability to produce healthy levels of glutathione and promote antioxidant activity.
  • Collagen is the most important building block of proteins, accounting for about 30% of all proteins. Collagen functions to support the integrity of tissues, such as bone, cartilage, skin, and tendons; collagen also functions as the fibers interlinking blood vessels, organs, bone, and muscle.
  • The triple-helical structure of collagen arises from the abundance of three amino acids: glycine, proline, and hydroxyproline.
  • Glycine is a conditional essential amino acid because the human body can synthesize it, but during times of stress or the overconsumption of oxygen (such as during exercise), the persistence of this inflammatory state depletes GSH, which in turn, depletes glycine levels.
  • Oxidative stress is a driver of inflammation due to the increase of reactive oxygen species (ROS) and reactive nitrogen species (RNS) and the release of pro-inflammatory cytokines. Under inflammatory conditions, during times of oxidative stress, when glycine levels are depleted, the body has a limited capacity to keep up with its collagen needs.
  • A variety of human conditions, normal and pathologic, involve the ability of tissues to repair. The biosynthesis of collagen is required for tissue repair as it is a major component of connective tissue and is a key element in the synthesis of protein.
  • Given glycine’s essential role in the creation of GSH and NAC’s equally significant role in the production of cysteine and GSH maintenance and metabolism, glycine and NAC are influential in the body’s ability to reduce inflammation caused by oxidative damage, improve muscle fatigue and pulmonary oxygen capacity, and facilitate the production of collagen and defend against muscle soreness.
  • Collagen and muscle protein synthesis increase after bouts of strenuous exercise; supplementation with collagen promotes muscle strength. Scientists suggest that the abundance of arginine and glycine in collagen stimulate creatine synthesis and as an effect, improve muscle mass.
  • In addition to glycine’s anti-inflammatory activities, one study found that supplementation with glycine increased human growth hormone in subjects, which regulates muscle growth and mass in humans.
  • The immune system, particularly natural killer cell activity (lymphocyte functions), is sensitive to changes in the DNA synthetic response to reactive oxygen intermediates, and therefore, favors high levels of glutathione. Research shows that patients with immunodeficiencies experience low levels of GSH, which are able to be reversed with treatment with NAC.
  • The amino acid glycine is involved in numerous metabolic functions, including the biosynthesis of glutathione, heme, creatine, nucleic acids, and uric acid, and the digestion of fat and of long-chain fatty acids. As a metabolic regulator and antioxidant, glycine helps to naturally support neurological functions, wound healing, immunity, and cardiovascular performance.
  • Research demonstrates that glycine supplementation may improve endothelial function; prevent cardiac hypertrophy, aid in the control of metabolic syndrome; prevent complications of diabetes; reduce inflammation; protect the liver; and improve the quality of one’s sleep.
  • NAC supplementation has been used as a treatment for several pathologies, including polycystic ovary syndrome; chronic bronchitis; ulcerative colitis; liver cancer; asthma; Alzheimer’s disease; Parkinson disease; cystic fibrosis; and nephropathy.
