Your body loses its antioxidative defenses during aging. Yet, many age-related changes (the ones that none of us want to see) are often a direct or indirect result of oxidative stress. N-acetyl cysteine (NAC) is a backbone molecule for glutathione, the body’s “master antioxidant.” NAC may also support clearance of toxins to help the body maintain optimal functioning and performance.*

Benefits:

Resists oxidative stress*
Supports immune, bronchial and respiratory health*
Supports liver health and detoxification*
Supports exercise performance*

Resists oxidative stress. NAC exhibits direct activity on certain reactive oxygen and nitrogen species due to its unique molecular structure. It also works to help increase intracellular cysteine for the maintenance of glutathione homeostasis. A systematic review and meta-analysis of trials involving NAC supplementation reported significant increases in antioxidant markers including glutathione, catalase, and Total Antioxidant Capacity. Research suggests that NAC paired with glycine, another building block for glutathione, may provide optimal protection from free radicals.*
$\"\"$
Supports immune, bronchial and respiratory health. NAC can help modulate critical pathways for an optimal immune response. It can also maintain and support normal physiological levels of mucus in the sinus and respiratory system of health individuals.*

Supports liver health and detoxification. NAC supports the body’s ability to excrete toxins through detoxification pathways by boosting glutathione production. NAC is a source of cysteine, an amino acid precursor for the synthesis of glutathione production. Glutathione is the body’s master antioxidant and plays a crucial role in liver health and detoxification.*

Supports exercise performance. Clinical studies have reported improvements in exercise performance markers in the presence of NAC due to its ability to help maintain free radical balance and support a normal inflammatory response.*

NAC helps support many of the hallmarks of aging through its support of free radical protection and glutathione synthesis. Low glutathione levels are common in older individuals.*
May work in tandem with glycine to support glutathione synthesis and overall health during the aging process.*
