The customer service is the absolute worst. There is no way to communicate with this company when something is wrong or want to return or cancel. It’s a full on scam.

To be honest, my mother who I purchased this for did not see any improvement in her severe anxiety. She needed prescribed medication from a physician. She had stopped taking NAC.

Love it and it seems to be helping my anxiety 😊
Emaline D. 5/5 Verified
It seems to help my anxiety
Emaline D. 5/5 Verified
It has reduced the anxiety attacks I was having, a real lifesaver. I only gave it 4 stars because I'm not through the first bottle yet and want to see if it continues to work over time. But so far it has been a god send.
Susan M. 4/5 Verified
This product has amazed me completely. Any purchaser of this product will enjoy the simple, easy to understand dosages recommendations. Additionally, you will know (after about 3 - 5 days) just how quickly it works causing you to feel more relaxed and alert simultaneously. I do recommend using this product.
Shirley H. 5/5 Verified
I've only been taking NAC for about a week. Yet I find myself waking clearer and having a bit more energy.
