Benefit and review
Acetylcysteine is a Dietary Supplement used as a liver antioxidant and has been studied for a number of decades. This antioxidant is commonly used by medical doctors and is available in hospitals in an intravenous form used to treat liver toxicity from acetaminophen (Tylenol) overdose. As an antioxidant, it can also be of benefit to many other tissues and organs, not just the liver.
Why take it? Benefits
N Acetyl l Cysteine (also spelled acetylcysteine, n-acetyl cysteine, n acetylcysteine, or NAC) is a form of an amino acid. It is a precursor in the body to the powerful antioxidant glutathione which is produced within cells, particularly by the liver.*

Dosage, amount to take
Q. What is the right n-acetyl cysteine dosage as a daily supplement?
A. There are no accepted guidelines on the appropriate n-acetyl cysteine daily dosage. Some people may need none, others may benefit from taking 500 mg of n-acetyl cysteine two or three days a week. If you are taking other antioxidants (for instance Acetyl l-carnitine, carnosine, Vitamin E, alpha lipoic acid), we suggest you reduce your dose of n-acetyl cysteine.
Additional information and metabolism, making more glutathione
N acetylcysteine is an excellent source of sulfhydryl groups and is converted in the body into metabolites capable of stimulating glutathione synthesis. Administration of n acetylcysteine has historically been as a mucolytic [mucus dissolving] agent in a variety of respiratory conditions. Acetylcysteine is often used in a hospital setting to protect the liver in cases of acetaminophen (Tylenol) overdose. In this situation, n acetylcysteine is given intravenously.*
Combination and interactions with other dietary supplements
Q. Can aceytylcysteine supplement be taken the same day as MultiVit Rx or alpha lipoic acid antioxidant?
A. If you plan to do so, we suggest using only half a capsule of acetylcystiene, and using this nutrient only 3 times a week.
Cysteine vs Acetylcysteine NAC
Q. What is the difference between cysteine and N Acetyl cysteine? Which one is better to take?
A. Most often n aceytylcysteine is the one taken since it has stronger antioxidant potential. However it depends on the condition being treated. NAC has an additional acetyl group which makes it more potent as an antioxidant.
Best antioxidants, so many to choose from
Q. There are so many antioxidant supplements to choose from, including acetylcysteine, alpha lipoic acid, acetylcarnitine, carnosine, mangosteen, acai, goji berry, pomegranate, resveratrol, lycopene, etc. Which one is the best?
A. It is impossible to predict which one of these in which dosage would be the best choice for a person to take. One option is to buy acetylcysteine and a few other supplements and then alternate their use. One day take acetylcysteine, another day take pomegranate extract, another day acetyl l-carnitine, the fourth day carnosine, etc. This way you expose your body to a variety of them each with their own benefit.
Capsules, vegetarian, vegan
Q. I am considering ordering your N-Acetyl-L-Cysteine ( N-A-C ), capsules and have a question. Are they vegetarian? I had read that some cysteine supplements are derived from human hair, are yours?
A. N Acetyl L Cysteine is made in the lab and it is not derived from animal sources. However the gelatin capsule is not vegetarian but you can open it by pulling on each side and just use the contents. Some people may only need a portion of a 500 mg capsule, and you can store the rest for another day.
Q. Since this supplement is beneficial to liver health, and so is silymarin derived from milk thistle, are there any safety concerns when combining them?
A. Not that we are aware of, but you may also consider alternating their use.
N-Acetylcysteine side effects, safety, caution
Large doses could cause nausea. N-acetylcysteine is not known to have any major side effects and appears to be a safe nutrient as long as the dosage is kept to less than 500 mg. See Acetylcysteine for the latest research and review on adverse reactions.
