Features
- Whole-body health all-star nutrient N-Acetyl-L-Cysteine (NAC for short) provides head-to-toe benefits. NAC is good for your respiratory system, liver health and immune response. Studies show NAC favorably affects cellular energy production, well-being and quality of life.
- Powerful protection against oxidative stress High-performing organs like your liver are exposed to free-radical agents that cause oxidative stress. N-Acetyl-L-Cysteine is a potent free-radical scavenger that combats oxidative stress. The body also uses NAC to replenish glutathione, a naturally occurring antioxidant that also helps protect your cells against oxidative stress.
- Easy-to-absorb NAC Each gluten-free capsule delivers 600 milligrams of N-Acetyl-L-Cysteine thats rapidly absorbed by the body, giving you the maximum benefits of this potent nutrient.
- Ingredients matter We use the finest raw ingredients chosen for quality and purity. The majority of our products are non-GMO, gluten-free and manufactured in the USA with globally sourced ingredients, and a Certificate of Analysis is available for each.

For the past three years I have been overworking on investment projects. This means 12 hour days six days a week on the computer. I strained my eyes so badly that I would see zig zag patterns dancing before my eyes. Scary! I went to see the eye doctor and after many many many tests he said I would need a treatment that comprised of EYE INJECTIONS! I had never heard of eye injection treatments before!!! I asked for the ingredients in the injections and the doctor gave a list of the ingredients. To my surprise I recognized two of the ingredients..Lutein and L Cysteine. I postponed the injection treatments and carefully, methodically, researched the vitamins and bought Life Extension N-Acetyl-L-Cysteine and Vitamins Because You're Worth it brand of Lutein. To my incredible good fortune the combination of the two vitamins stopped the dancing zig zag patterns within two to three minutes of taking the vitamins!! Yes!! Hard to believe but it is the truth!! Whenever the zig zag patterns appeared, I took the vitamins. And every time the zig zag patterns went away very quickly. I also began to take breaks every hour, and then stopped working 12 hours a day on the computer. The result is, I did not need to take the eye injection treatments!! The doctor said in his entire career he had never seen such severe eye problems resolve itself. He happily told me I don't need the eye injection treatments. This is the truth. That is how powerful this combination of these two vitamins from the specific brands perform. It is critical to take the two vitamins together for synergy. Also the brand matters. Because the two brands do not use fillers or flow agents. And they do NOT contain beeswax or palm oil. Ingesting beeswax on an ongoing basis will eventually cause blockage in the intestines. Deadly! Be sure to check the lables and do NOT buy any product that contains beeswax or palm oil. Even check the vitamin of another kind from the same label. Why? Because that brand may not use beeswax in one type of vitamin but may use beeswax in another type of vitamin. Be forewarned!! The Vitamins Because You're Worth It brand of Lutein disappeared from Amazon. I searched for it for months and came across one source on the internet that sold a bottle of that label for $60. I paid $12 on Amazon when I bought it. I eventually found Naturebell Lutein 40 mg 360 capsules plus it has something that Vitamins Because You're worth it did not have...Zeaxanthin. BUT the capsules are coated with Krill oil and has a slight distinct fishy smell. The smell does not bother me. And I am not allergic to krill or krill oil. Some people ARE allergic to krill and krill oil. If you are then Nautrebell will not be suitable for you. I would like to confide something more because your health is important. Here it goes... This is my second time I am posting a review of Life Extension N-Acetyl-LCysteine. My first post was receivng upvotes everyday. It had come to almost 70 upvotes and going up and up. Then I updated my review to add information about another vitamin from Life Extension that contained two ingredients that I know is bad for the health and should never be ever ingested. Within two days my review of Life Extension N-Acetyl-L-Cysteine was removed. While I did not want to spend precious time rewriting my review I am taking the time because if we do not have eyesight our lives would be very different and the loss of our eyesight could never be made whole no matter how much money we have or what we achieve. To me, if I am censored for sharing information that will impact our health then I am seriously considering not buying any product from Life Extension even when I really love the L Cysteine. And I wonder if this review will be taken down. I made sersious effort to get my original review to be reinstated but all the work was futile. Thank you for reading my review. Please know my heart wishes for you a life filled with happiness, love, and great health.

I've been coming off years of poor health. Feeling lethargic. Depressed. Etc.. unfortunately I tried just about everything else under the sun( pharmaceutical, supplement). I really felt hopeless. After watching a you tube video of Dr Eric Berg. I ordered this product. I did not achieve any results until I started taking it three times a day. Within a 48 hrs I began to feel normal. My sleep is returning to normal. I can get through the day without a thought of rest. My irrational future tripping has disappeared. No more tight chest or twitching. I was obviously not in symbiosis. I can't believe that a solution this simple has evaded me for years. I've had blood work done many times and it didn't reflect any deficiency because what was there wasn't making it to my cells. The glycinate is key to that. I wouldn't waste my time writing this if it didn't really turn things around for me. I hope this helps someone who is in the desperate position I was. Good luck

When I first opened the bottle, I noticed a bit of a rotten egg smell, but I found out that’s normal for NAC and actually means it’s legit. The capsules themselves are easy to swallow and don’t have any weird aftertaste. I like that the bottle feels well made and the label is clear and simple. After taking these for a few weeks, I feel like my energy has been steadier and I recover a little quicker from hangovers. It’s not a dramatic change, but I can tell it’s doing something. Best part is it hasn’t upset my stomach, which I’ve run into with other supplements. Overall, I trust this brand and plan on keeping NAC in my routine.

This helps my adhd and my old pucking or from. Nerves either way , 1200mg is the ticket . After 6 weeks I can feel a difference in my adhd ( calmer ) and my compulsive tik like picking and scratching . It's not a co plate stop but if gives me the time to stop it myself.

Omg, this stuff helped me so much. I could tell a difference when it kicked in which was thankfully pretty fast. My brain felt less foggy, I felt less on edge, I was able to remain calm in a stressful situation. What a godsend! I can imagine the good things it's doing for me on a chemical level. A quick note: it smells bad, but that's expected/normal for this supplement apparently. I hope the effects remain positive and that it works this well for everyone!
