About this item

Highlights

  • ANTIOXIDANT SUPPORT FOR YOUR LIVER: Free radicals can cause oxidative damage to your liver, but NAC is necessary for the regeneration of glutathione, a potent antioxidant that binds with and neutralizes free radicals. NAC is the stable form of the amino acid L-Cysteine and works to stabilize the formation of protein structures, which supports cellular health.
  • PROMOTES HEALTHY AGING: NAC has earned a reputation as a free radical scavenger due to its ability to promote glutathione preservation, which helps prevent oxidative damage while also having a healthy aging effect.
  • SUPPORTS DETOXIFICATION: The thiol groups within NAC helps to bind with toxins in our body which come from things like environmental pollutants. NAC helps to support our body's natural detoxification processes.
  • DOSAGE INSTRUCTIONS: As a dietary supplement, take one capsule per day with water or as recommended by your healthcare provider.
  • FORMULATED WITH SCIENCE, expertly crafted WITH CARE: Based in Fargo, ND, our team of pharmacists, scientists, food nutritionists & quality experts ensure that every product is tested in accordance with the FDA.

    Highly recommend NAC for daily immune support

    I learned about the advantages of taking NAC during the COVID19 Era. It was suggested as preventative and also treatment for viruses by an Integrative Health Clinic. I have found that it does a great job in supporting my immune system and I love the ease of using a subscription and the price!

    A bit early to tell but seems like a winner

    It seems to be helping. I don't really know yet. I guess we will see. I do notice a difference in how I feel if I miss a couple of days of them though.

    Helps my COPD

    I have COPD and I have been taking NAC for years to help my breathing. In addition to being a strong antioxidant, it helps to clear out the mucus that clogs up the lungs and airways, and it has definitely improved my breathing.

    Clean product and it’s easy to swallow, all at a very reasonable price. NAC is a precursor to the production of glutathione within the body, which is a potent antioxidant and aids many metabolic processes.

    What is in these capsules?

    I don't know what is inside these capsules, but it is not N-Acetyl Cysteine (NAC). If you read any articles or reviews about NAC, you will notice that many of the comments mention the sulfurous odor. This is because it has a sulfur base, it's a natural odor. When I opened the bottle of Swanson NAC, there was no odor at all. I even opened a capsule and smelled the powder, nothing. I tried crushing the powder, still no odor. If this is Swanson's idea of quality control, I'll buy all my supplements elsewhere.

    The Proper NAC

    There are several doctors who discuss the respiratory benefits of this product on You Tube. So I decided to purchase two bottles of the Swanson brand. I was very disappointed. I had taken one whole bottle, and saw No difference. The doctors state how you know it is a good brand, it should have a smell of rotten eggs. This brand had no smell. Tried a different brand, it had the rotten egg smell, and you could tell the difference immediately. The stronger brand, you could not take on an empty stomach. I took two of the Swanson brand and I didn't notice any difference.

    Should smell like Sulfur

    I don't know. It's my understanding that for the NAC to be potent, the supplements should smell like sulfur. These do not smell. I learned that after buying these, but I recall reading reviews of products about the smell. I don't see them for this one. Also, I haven't noticed an improvement in my mucus issues.

    Must have if you take acetaminophen

    My doctor recommended this because of my daily acetaminophen use. After just one month of taking NAC, my kidney numbers looked so much better than before!

    NAC for Anxiety Reduction

    I took NAC for 6 months as an off-label anxiety reducer as recommended by my doctor. Unfortunately, it didn't help me in the way my doctor and I were hoping, but hopefully it works for someone else!

    NAC great, taken daily, keeps bugs at bay!

    NAC is great at keeping the bugs at bay, taken daily, & it's not too pricey. IF you do succumb to some bug, then get beta glucan, if you can (it costs a bit more, but worth 'getting better")

    Former Firefighter Recommended. Works great, could save lives.

    As a former volunteer firefighter/EMT that still smokes (organic) tobacco cigarettes, I love NAC for a multitude of it's benefits. Works great for me, great value, protects my families health. Lots of research out there proving why some interests try to ban it.... but we see through the lies and illusions. No downsides for me personally, all benefits, would recommend to almost anyone.

    Didn't work for me

    My psychatrist suggested taking this to help resolve my issues with skin picking. This supplement isn't for me. I tried taking it for a few days and broke out in an itchy rash on my wrists, ankles, chest, back, and shoulders. After some weeks, I decided to give it a second try and the same thing happened.
