NAC (N-Acetyl-L-Cysteine)

Supports the body's natural glutathione production – According to a study that appeared in the journal Innovations in Clinical Neuroscience, NAC plays a crucial role in your body's natural production of the antioxidant glutathione. It works with two other amino acids, glycine and glutamine, to create glutathione. NAC can help maintain optimal glutathione levels.

Supports healthy cognitive function – Low levels of glutathione in the brain are associated with poor cognitive health. Not only does NAC serve as a neurotransmitter, but it can also support healthy levels of glutathione in your brain for optimal cognitive function. Additionally, NAC possesses potent antioxidant properties that can help protect your brain from oxidative damage.

Supports healthy immune function – According to a 2007 study that appeared in the Cambridge University Press, supplementing with NAC can support the optimal functioning of your immune system. As a potent antioxidant, NAC can also provide further support for your natural immune defenses.

Supports healthy cardiovascular function – According to a study that was published in the American Journal of Clinical Nutrition, NAC supports a healthy cardiovascular system by protecting the heart from oxidative damage and helping maintain blood pressure levels that are already within the normal range. 

Supports healthy respiratory function – Cysteine can normally be found in your lung tissue, which means this amino acid plays an important role in healthy respiratory function. Supplementing with NAC can support a healthy respiratory system and help maintain optimal glutathione levels in your lungs that are already within the normal range. 

Supports healthy reproductive function – According to a study that was published in The Journal of Urology, regularly supplementing with NAC and selenium can support optimal reproductive health and fertility in healthy adults.

Supports healthy kidney and liver functions – By maintaining optimal levels of glutathione in your liver and kidneys, NAC can support your body's natural ability to flush out unwanted toxins and heavy metals. This also eases the strain on your kidneys and liver, allowing them to function optimally.

Supports the growth of healthy skin – NAC is often found in skin creams and gels due to its skin-nourishing properties. Supplementing with NAC can support optimal antioxidant activity in your skin, which can in turn protect your skin from oxidative damage and maintain healthy, glowing skin.
