Groovy Bee® NAC (N-Acetyl-L-Cysteine) 500mg 90 Caps
Support Glutathione Production

Cysteine is a sulfur-containing amino acid that is one of the most important amino acids your body requires for optimal health. This semi-essential amino acid serves many functions in your body, such as acting as a neurotransmitter and supporting the healthy production of the master antioxidant, glutathione. As you age, your body's natural production of cysteine declines. That's why the Brighteon Store is bringing back lab-verified N-acetylcysteine (NAC) supplements.

Groovy Bee® NAC (N-Acetyl-L-Cysteine) makes it easy for you to maintain healthy levels of cysteine so you can keep your body in peak physical condition. Each capsule of Groovy Bee® NAC delivers 500 mg of pure N-Acetyl-L-Cysteine to promote overall health and well-being, as well as help to support your body's natural production of the antioxidant glutathione.

Groovy Bee® NAC (N-Acetyl-L-Cysteine) contains no GMOs, artificial colors, flavorings or fillers. It is also vegan, non-irradiated, non-China, and lab tested for glyphosate, heavy metals and microbiology.

Health benefits of NAC**

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.

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.

NAC can help maintain optimal glutathione levels**

Also known as your body's “master antioxidant," glutathione is simply one of the most important antioxidants in the human body. It helps protect cells against the harmful effects of free radicals. Cysteine is a crucial component in your body's natural production of glutathione. Without enough of it, you'll be in danger of glutathione deficiency, which can negatively impact your overall health and well-being.

Since natural glutathione production declines with age, it is important to supplement it, to give your body all the support it needs. Fortunately, you can maintain healthy glutathione levels through the regular consumption of cysteine in the form of NAC. This lab-verified supplement provides extra antioxidant support to help protect your body against free radical damage.

NAC provides a two-fold effect on your body, being both a potent antioxidant on its own as well as a crucial component of natural glutathione production. NAC and glutathione then work together to combat oxidative stress in your body and support your overall health.

Customer Reviews

Excellent Product! Excellent Quality!

This is one of my favorite products at the NN store. Definitely notice a difference when I take it and when I don't take it. Thanks so much for carrying this product!

Glad to have on hand

Glad to have NAC on hand since it's getting harder to come by, esp with gubmint overreach.
