    I have purchased a number of these from this company, and have now completed a month of usage. I can attest to the validity of this product, due to the overall feeling of clarity and additional health benefits. Great company, fast shipping, and excellent results. Cheers.

    I’m having issues with my liver enzymes being high. Hoping this help !!!

    I consistently have acute bronchitis and constantly have severe asthma – since taking NAC along with my other maintenance prescriptions I have completely stopped my rescue inhaler and nebulizer treatments. I am so pleased I got 2 years worth because that was the bestbuy date on my first bottle! Great product, results.

    Heard about this from some podcast that I listen too. I let my co-worker know about this when she got Covid and she felt better they next day. I had Covid myself and I have been taking these once a day to keep up my immune system. Keep in mind it’s not a Cure for Covid but it helps fight it. Thanks so much Gridiron for keeping honest prices and the shipping was fast!

    I’m wanting this for breathing and fatigue in long covid. Anyone had any positive results?

    Payment Question: Do you accept credit/debit card payments because when I go to enter my payment method it only gives me the option to enter bank account routing and account number. I do not feel comfortable with this method of payment, it is not secure.

      Hi Lisa,
      We do accept credit/debit cards. I’m not sure why you’ve been unable to do so. Please send an email to with more information and we will fix the problem.

    There was a mistake in the shipping and when I emailed the company the owner replied so quickly and fixed the problem immediately. I was very impressed how well it was handled. I haven’t tried the product yet but just wanted to say thanks for the great customer service.

    I tried this out because of all of the people who are getting injected with the poison shots and are shedding the spike proteins all over the place. It has significantly gotten my energy levels back to normal and I have purchased 3 more.
