Jarrow Formulas, N-A-C Sustain, N-Acetyl-L-Cysteine, 600 mg, 100 Tablets

Don't waste your money on this old NAC from this seller because it doesn't work.I've been using NAC for years and can't live without it. I bought it from this seller, Rowhen, because it was cheaper. I spent $75 on 3 bottles. They all have a date of 2019 on them and no expiration date, whereas an old NAC bottle that I bought a while back has a 2022 date and a 2024 expiration. (This product is on the right in the pictures; the NAC I bought earlier is on the left.)When I received the bottles, they were all scratched up, which made me inspect them more closely than I normally would. I noticed the 2019 date at that time, but I figured they were probably good for several years and would have an expiration date if they needed one. I didn't start taking any of these new bottles of NAC until a few weeks later.I couldn't figure out why I'd been feeling so terrible the last few weeks until I remembered that this NAC is old and considered it might not be effective. I found a bottle of NOW NAC (that I bought before the NAC ban), took one of those, and I felt good again. I've been taking those since then and have felt fine. Unfortunately, because I didn't start taking these right after I got them, and it took me a while to figure out they didn't work, my return window has closed.
