    My NAC supplement arrived immediately. The price is fantastic and I appreciate that. Please don’t increase the price. I like that it has NAC and not other unnecessary ingredients. I also like the fact that it is made here in Kentucky, USA. The company has very responsive customer service and they’ll expedite your order. I’ve never had any issues with my order. Best of all, this product has completely changed my life. I suffer from allergies and this product has helped me tremendously with my breathing. I will continue to order from this company and I highly recommend this product.

    I’ve been taking NAC for about a year now, and I’m no longer on albuterol for my asthma. No more inhalers or nebulizer for me. One year asthma free. This stuff is amazing! Thankful I bought a two year supply. Keep NAC available for the people, it really works!!!

    I’m very pleased with my purchase of NAC from Gridiron.com. The product is of exceptional quality and affordable for seniors like me who are on a fixed income. NAC is invaluable for asthma patients, as well as being effective for other lung problems. I’ve even heard of it being helpful for Covid 19 infection and the associated breathing difficulties. So much so that the FDA wants to make NAC a prescription only item. Trust the government to monetize a safe, lifesaving treatment and guarantee that it becomes unavailable to millions of people. This is going to be a death sentence for many folks!

    NAC was recommended to me by my pulmonologist as a supplement to my prescription therapy. The purpose of NAC is too thin out mucus. That’s what it does. It is not for all of these other claims, like Covid prevention! Unfortunately unscrupulous manufacturers have touted NAC like some kind of snake oil and now it’s being taken off the market for false labeling claims. I’m angry because now I can no longer get it for it’s intended use. Hopefully it will still be available with honest labeling for those of us who actually need it.

    This has been a Godsend for my college age daughter with low immunoglobulins. This has protected her during the pandemic and helped to boost her system and maintain overall health. Too bad it’s benefits infringe on big pharma, so it will no longer be sold. We bought a two year supply.

    Recommended by Dr. Lee Merritt along with Vitamin D3, Zinc, and Selenium daily. I started taking these since late 2020. Been tested negative several times for Covid since. I have not been vaccinated. I have been tested positive for the Covid antibodies in my immune system, and have never been sick, so I continue to take these supplements to boost it. I am 70 yrs old with Type 2 diabetes and still scuba dive. So go figure…. Bought a 3 year supply.
