Bests & Worsts Reviews from Amazon

After reading so many positive reviews, I was excited to use an NAC supplement and these sounded like the best. Unfortunately, I didn’t read any warning to look out for NAC possibly triggering a histamine reaction. I started getting itchy for days and then it worsened into a full body rash and hives that wouldn’t go away even with Benadryl round the clock for a week. I didn’t connect this supplement could be the culprit at first until I looked up possible adverse reactions. For some people NAC triggers a strong histamine response and causes rash. Even after stopping it for a week the rash/hives wouldn't stop. I finally went to the doctors to get a steroid prescription and pray it will stop in 5 days. So, while I love supplements, I have to caution buyers who want to try this one to be watching out for itching when they start because they might be one of the people who gets triggered into a severe persistent rash. It’s miserable!
