Nausea caused concern
100 people found this helpful
I decided to write a review after finding a half-used bottle of this NAC. I had a headache and took Tylenol, which made me feel very ill for hours. I later learned that bee propolis and Tylenol can interact, making me unwell. I took some NAC with vitamin C, which helped overnight. I’ve noticed this brand’s NAC lacks a foul smell, unlike others I’ve tried, which caused me nausea and heartburn. This brand seems amazing, and I hope the quality remains consistent.

I bought this for my husband, who has been experiencing skin spots and fatigue. While he hasn't seen results yet, he doesn't seem to have discomfort. I tried it twice but had severe nausea and stomach pains, leading to a systemic rejection reaction. I stopped due to the pain; he might continue, but it seems personal reactions vary.

Excellent! I was recommended this for liver health; it's easy to swallow unlike powder products that cause nausea. The benefits are tremendous. Highly recommended.

UNPLEASANT ODOR! The smell is nauseating and reminds me of sewers. I am very disappointed as this has affected my trust in the product. I hope I do not face any problems due to this unpleasant scent!

I used N-acetyl-l-cysteine for 21 days, taking one capsule twice daily. Unfortunately, it did not work for me. I experienced fatigue, nausea, and depression during this time and ultimately decided to stop taking it.

I recently started taking NAC daily and am pleasantly surprised. I've gained energy and improved respiratory function, with potential liver benefits too. I had mild nausea when I first started, but it subsided quickly. Overall, I'm satisfied and would recommend NAC as an effective supplement.
