NAC Sustain 100 tablets - N-acetyl-cysteine | Jarrow Formulas
Jarrow Formulas NAC Sustain is in a bilayer Quick Release / Sustained Release format of N-Acetyl-L-Cysteine (NAC). N-Acetyl L-Cysteine, a sulfur amino compound which plays an all important role in the production of the body dominant and essential antioxidant Glutathione. Optimal Glutathione levels are important for a healthy immune system and the cell defense against viral infections.
NAC Sustain releases in the small intestine over a 4 hour period, compared to the 1.5 hour biological half-life of NAC in the bloodstream.
NAC's primary efficacy is shown when it is needed to regenerate glutathione after overdoses of certain NSAIDs like aspirin or acetaminophen which may lead to a depletion of liver glutathione stores. The more stress is placed on the liver, the faster this may lead to a dysfunctional liver and cause death.
People who cough up a lot of sputum know NAC as an agent capable of reducing the sulfur found in mucus and break it down to a more liquid form.
In athletic circles NAC is widely used as an anti-oxidant. Some athletes claim to perform better with NAC supplementation than without. Plausibly caused by the vasodilating effects of acetylcysteine. But NAC supplementation has further use as it has shown to slow down platelet aggregation.
N-Acetyl Cysteine is a better alternative than cysteine which can be obtained from dietary sources like egg whites or dairy products. Simply due to the fact that it is rapidly absorbed from the gut and finds its way to the liver and other areas in the body where L-cysteine is needed. It also works twice as long in the body than just dietary cysteine.
• strengthens the immune system
• n-acetyl cysteine boost nitric oxide synthesis which causes increased blood flow to the muscles
• benefits people with breathing problems
• slows down platelet aggregation
• increases glutathione stores which in turn help to protect the liver from overdose on
drugs like acetaminophen and other NSAIDs
NAC - a better source of L-cysteine
Jarrow Formulas NAC (N-acetyl cysteine) is a stable form of the amino acid L-cysteine. It is essentially a combination of cysteine and acetic acid, which is a primary component of vinegar. N-A-C is cysteine that has been modifi ed with an acetyl group, which is how many compounds with health benefi ts (e.g., aspirin, omega-3 fatty acids) are stabilized and made more bioavailable.
L-cysteine, like cystine and taurine, is a sulfur-containing amino acid that can be produced by the body from the essential amino acid methionine. It is considered a non-essential amino acid for this reason, but is conditionally essential in infants and with certain nutrient deficiencies or debilitating conditions. Inadequate methionine in the diet, low selenium intake, chronic disease and advancing age reduce the body’s ability to convert methionine to cysteine.
Likewise, stress and environmental toxins may increase the need for cysteine beyond the body’s capacity for conversion. N-A-C is preferred to cysteine, or cysteine, as a supplement because of its stability, solubility and greater ability to donate sulfur.
Glutathione: building your own antioxidant
N-A-C supplies readily available L-cysteine, which acts as an antioxidant itself or as a precursor to glutathione. Glutathione is one of the body’s most important and abundant antioxidants inside of cells. The primary antioxidant mechanism involves the donation of an electron from the sulfhydryl (-SH) group of the cysteine molecule. Sulfhydryl-containing substances like N-A-C, cysteine, glutathione and alpha-lipoic acid are referred to as reducing agents. This is opposed to oxidizing agents. Since reducing agents have opposing chemical functionality to oxidizing agents, reducing agents are also anti-oxidizing agents—or antioxidants. Antioxidants guard against the production and propagation of free radicals caused by oxidation.
Antioxidants like cysteine act as electron donors and receptors to neutralize uncontrolled free radicals without becoming reactive or toxic themselves. Glutathione, which contains cysteine, donates its own electrons to free radicals to reduce them to stable compounds. One example is the transformation of superoxide or peroxide to water.
In the process, glutathione becomes oxidized. It is then reactivated by the donation of an electron to become reduced glutathione thereby making it electron-rich again and ready to scavenge yet more free radicals. Making cysteine more available to the body encourages the production of glutathione. Cysteine is an antioxidant in its own right by virtue of its sulfhydryl group, and plays a vital role in the stability and functioning of proteins. Cysteine, in proteins, also interacts with iron and zinc in the body to form enzymes that help coordinate respiration, energy production, immune surveillance and repair functions in all tissues.
It is important to note that in hospital practice, N-A-C is given rather than reduced glutathione to support blood levels of glutathione. N-A-C is also well supported in clinical trials involving antioxidant therapy.
An antidote to liver toxins
Brief mention should be made of the benefi ts of N-A-C in controlling environmental and other toxins. Cysteine can neutralize chemicals known as aldehydes produced by air pollutants (i.e., smoke), some drugs, and by the liver as a byproduct of alcohol metabolism.
N-A-C is therefore important for maintaining the body’s antioxidant defenses in the face of everyday assaults. N-A-C is routinely used in hospitals as an antidote to the pain reliever acetaminophen, particularly when ingested with alcohol, or taken in excessive amounts. Acetaminophen poisoning is the most common cause of calls to poison control centers in the United States. It causes severe damage to the liver, much the same as that caused by the toxic mushroom Amanita phalloides. N-A-C supports the health of liver tissue by replenishing liver glutathione levels and also by enhancing the delivery of oxygen to liver cells.
Advantages of NAC Sustain
NAC Sustain is a bilayer Quick Release/Sustained Release N-A-C formulation. One third of the N-A-C releases rapidly and two thirds releases slowly over time. This raises blood levels quickly while also sustaining them.
N-A-C Sustain releases in the small intestine over a 4 hour period, which greatly assists in prolonging N-A-C antioxidant protection over the typical biological half-life (1.5 hours) of N-A-C in the bloodstream.
Some supplements are suitable for both men and women of all ages as well as children. But other supplements are specifically targeted to the aging woman or man. Another supplement is especially suitable for athletes, regardless of gender.

Exercise and immunity: staying fit at home
When you are used to go to a gym to exercise and are forced to stay at home, it is good to know there are alternatives to gym workouts. Since most of those exercises are shown on short videos with an explanation we will not present much text this time , apart from explaining why exercise is so important for immune system.
How to prevent getting sick from the flu
You can prevent germs from making you ill in two ways: prevent entry into the body by careful hygiene, and if they do get in, make sure your body’s natural immune system is able to fight these germs, so they self-destruct before overwhelming the system.
Most flu germs are spread in two ways:
- touching such as hand-to-hand contact
- droplet spread when germs ride along on tiny water droplets that are sneezed or coughed into the air
Try these flu prevention tips to avoid person-to-person spread:
- avoid shaking hands, but bow or give a head nod
- avoid nose-picking as the nose is a breeding ground for germs
- sneeze into a disposable handkerchief and if you don't have one available, sneeze inside your elbow
- shun coughers and sneezers as much as possible.
- avoid crowded rooms
PFAS pollutants causing turmoil
In October, nearly every construction project came to a grinding halt in the Netherlands, because not a single project except the smallest ones can be completed without excessive paper work or laboratory tests.
Why? The current legal threshold for PFAS, an abbreviation for perfluorinated alkylated substances has been set extremely low until the government is able to define a proper health limit for contaminated soil so as to prevent contamination of clean soil with more heavily contaminated soil.
If cemeteries hadn't been exempt from the rule, not a single dead body could have been interred, since PFAS-chemicals , also known as 'forever chemicals' have accumulated in our bodies to an extent that exceeds the legally set threshold, which is currently as low as the lowest possible detection level.
Why is glutathione so important for your health?
Glutathione is one of the body’s most important and potent antioxidants. Antioxidants are substances that reduce oxidative stress by combating free radicals in the body.
While most antioxidants are found in the foods you eat, glutathione is produced by your body. It is primarily made up of three amino acids: glutamine, glycine and cysteine.
There are a number of reasons why your body’s glutathione level may become depleted, including poor diet, chronic disease, infection and constant stress.
Glutathione is also known to decrease with age.
Maintaining adequate levels of this antioxidant is incredibly important. Below are some of the best ways to increase your glutathione levels naturally.
How to cure a hangover
Quite a lot of people wake up the day after a major holiday like the recent King's Day or Liberation Day with a hangover due to imbibing too much alcohol.
The most widespread assumption is that a hangover is caused by not drinking enough water, and therefore those that aren't drunk enough to remember what to do, will drink a few litres of water before going to bed or at least will try to do so the next morning. Other very popular cures are to drink a lot of coffee and eat a hearty egg-based breakfast. Another advice was heard on the radio from a Dutch food blogger who exclaimed how eating toast with honey is a definite cure for hangovers. Around the world a myriad of folk remedies exist for this ancient 'disease'.
Do these remedies actually work and are there some others you didn't think of?
Before we dive into that, let's first discuss the hangover itself.
Breathe in, breathe out!Did you ever notice you don't have equal air flow through each nostril? Most people alternate between breathing through the left and the right nostril. The only time you are vividly aware of the existence of such a cycle is when you have congestion in just one side of the nose, which results in only being able to breathe more easily every few hours and then feel congested in the other period.
When is drinking alcohol bad for your health?In the past decade we were told indulging in one or two glasses of alcohol (just one for women) a day is healthy. This was even one of the many recommendations in the national (Dutch) health guidelines. In the past year though, a drastic change occurred: the recommendation changed into zero to perhaps to a most one glass of alcohol a day! So, what gives?
How to eliminate toxins?A while ago, there was a major uproar in the Dutch media about an advice given by a celeb health enthusiast to drink a glass of water with clay in order to 'detox' the body.
Unfortunately, while it is true that clay can bind to toxins, clay is not the best choice for two reasons. The clay itself can be polluted, but moreso, clay isn't the best option.
