Review: Very beneficial - Excellent product!
Review: I use Life Extension N-Acetyl-L-Cysteine for superb Optimal Eye Health - 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 desertcart. 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 desertcart 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.

### ⭐⭐⭐⭐⭐ A Godsend!
*by B***I on July 30, 2025*

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!
