NAC is essential for balancing my methylation daily. I take one of these with breakfast and one with dinner along with other methyl donors (primarily P-5-P and Methylfolate). I can't stress how important the addition of selenium is in the ingredients of this one - it makes a MASSIVE difference to the efficacy of NAC for me. If I take this one, or one of the others with selenium (eg. Lake Avenue) I feel super balanced all day. If I take one of the others brands, in the same 600mg dosage, that hasn't got selenium with it, I end up feeling like I'm under-methylating within and hour or two and have to take almost double the amount to get the same methyl-balancing effect that the addition of the selenium creates with just a single dose.

When I started taking this I noticed a really positive difference. It massively helps my aerobic capacity, general stuffiness, and my skin tone looks great. However, when I started on NAC years ago I did so with a time-release form, and used three versions of similar. I think they all had a noticeable edge over this one, with quite pronounced effects. They say this stuff does not have the best bioavailability, and I believe this is not hype at all. With the sustained forms the effect really lasts. The main thing is the price of this one is much cheaper than those forms for the dosage you get. The ingredient NAC is a precursor to glutathione - a powerful antioxidant against oxidative stress.

The size of this package at 100 capsules means I don't have to stock up that often. You don't get much NAC in your diet alone, so it is vital to supplement.

I don't doubt the brand - or the quality of the supplement.But just be very careful, when taking this when you have underlying health issues. For me, I have Long Covid. I've been looking at ways to address the crippling fatigue. This product came recommended as part of an overall mitochondrial support regimen.Luckily, I track everything. Within 3 days of taking this product - I started to develop fatigue, malaise and really intense heart palpitations. I persevered for a few more days (that's how desperate I was for this to supplement to benefit me)....which on reflection was probably not a good idea. My symptoms gradually worsened - particularly the heart palpitations, anxiety and stress. I stopped taking the supplement and within a couple days I was back to ... MoreI don't doubt the brand - or the quality of the supplement.But just be very careful, when taking this when you have underlying health issues.

I stopped taking the supplement and within a couple days I was back to normal.Like I say, we all take supplements in the hope to see some kind of health benefit/improvement. Just be very mindful (and on the lookout) for side effects. They tend to build over the first 3-5-7 days. You might not be able to put your finger on it.....but whatever you do....ALWAYS BE PREPARED TO STOP NO MATTER HOW MUCH YOU WANT/NEED IT TO WORK.In summary then, if you have any pre-existing inflammatory condition, already suffer from heart palpitations/racing heart etc....tread carefully and don't exceed 1g per day during your first week.
When this is available, it's my go-to NAC. It's often out of stock, so I end up alternating between this and the Lake Avenue one which has an identical composition. I have a methylation disorder and MCAS, so I'm always well stocked with NAC for methylation balance and detox assistance (which helps lower my MCAS reactivity). I always make sure I have two different types of NAC in the cupboard - one like this Now Foods one with added Selenium (trace element that significantly add to its efficacy) and one without from a different brand in the same 600mg dosage. I've always been able to feel the difference, particularly to my methylation, when I take this Now Foods NAC with the added selenium. For that reason this is the standard NAC I take every day as part of my ... MoreWhen this is available, it's my go-to NAC.

I always make sure I have two different types of NAC in the cupboard - one like this Now Foods one with added Selenium (trace element that significantly add to its efficacy) and one without from a different brand in the same 600mg dosage. I've always been able to feel the difference, particularly to my methylation, when I take this Now Foods NAC with the added selenium. For that reason this is the standard NAC I take every day as part of my supplement regime (or the Lake Avenue alternative) as it contains the Selenium. I take one 600mg with breakfast, and one with dinner everyday without fail and that (along with methyl folate, P5P and others) keeps my methylation fairly stable. There are times though, when I'm particularly stressed and under-methylating, or I've had an MCAS inflammatory episode, or been exposed to chemicals or high levels of pollution, that I'll need to take more NAC in one day. In that instance I don't want to take more of this one with the selenium because I want to make sure I don't triple-down on those trace elements and build up unhealthy levels. So I always keep some pure NAC on hand for those times when my body is crying out for more N-Acetyl Cysteine, but I don't want to pile on more Selenium (my choice of pure NAC in the same dosage is by Life Extension). Bottom line is that this NAC is excellent and super effective at influencing methylation and supporting liver detox and health. Just watch you don't take more than the suggested dose and cop too much selenium.
N-acetylcysteine ​​or NAC is the acetylated form of the conditionally essential amino acid cysteine, which means that our body cannot produce it on its own, so we need to ensure its intake ourselves. Amino acids are extremely important for our body because they are among the basic building blocks of proteins. NAC is also a precursor to glutathione, which is present in all cells of our body, especially in the liver, where it binds harmful substances. The quality is at a high level and the package is optimal. The ingredients are pretty good and high quality, pure and clean.Thank you for reading and for your attention. If you like this text, please like it to support me. Thank you in advance for your understanding and patience.
I have dysautonomia and I'm alpha1 deficient, so if I get too stressed my lungs get inflamed. About a year ago my dermatologist recommended to me when I asked her about supplements that might reduce inflammation... I loved it, I took 600mg 2x per day (one in the morning and then night) every day for about 3 months. My immunologist told me I could take it forever but still it was good to cycle it. These days I only take it when I need to.It doesn't smell as bad as other NAC supplements, mind you, still has sulfur, so if sulfur doesn't suit you perhaps this isn't for you. It might also deplete zinc and other minerals so make sure to supplement on that, or check your levels.This formulation by the brand NOW includes molybdenum which is good for cognition.

All in all, I recommend it.
I began taking NAC pre-COV for the oxidative effects and glowy skin, I had great results, but I slowly fell off. Caught COV in Jan 23, researched what to take because I did not and will not take their vax. I found a supplement protocol from a Dr on YouTube and it included 1200-1800mg NAC daily. [Along with quecertin, vitamin b complex, vitamin c, vitamin d3, zinc. Please do your research but it worked for me.] I did not have all the crazy side effects that many people report during and after COV. I stopped taking it again about a month later. Now I’m back again, for over all wellness… and the glowy skin, because why not?! I will be taking this with a long list of other supplements that work well for my blood type and a 90% clean diet.

Staved off flu going around in adults and children of various ages in our family. 11 yo daughter’s cold turned into tight chesty cough for 3 days with onion poultices offering no loosening of phlegm. Took NAC and started working within HOURS, that night phlegm let loose and continued on NAC 3 days till all symptoms disappeared. Toddler came down with same problem a week later but had a hard time giving small doses of NAC so illness turned into viral pneumonia symptoms. Between getting the NAC in with juice and breastfeeding for fluids we avoided hospitalisation and fever broke after day 3 and sleepness nights for me. Spoke to health nurse about fever and rapid breathing and they were happy for me to keep her home. So very happy NAC did the trick and she is up and ... MoreStaved off flu going around in adults and children of various ages in our family. 11 yo daughter’s cold turned into tight chesty cough for 3 days with onion poultices offering no loosening of phlegm.

Let's share the results.When I woke up in the morning, I felt as if I was tired from not having a good night's sleep, my muscles did not like it, I wanted to get up after drinking tea and go back to bed. There was no productivity during the day at work.Then took Glycina+NAC together for a few days. Since glycine tastes like a nice candy, it is used instead of sugar in tea and coffee in the morning and evening, so the consumption of sugar has decreased.It's like I wasn't watching my body. After a few days after using it, I suddenly no longer feel tired when I wake up in the morning.I realized that there is no need to suffer and be tired when there are so many opportunities to recharge yourself, thank you admin. NAK glycine is great for long-term use.
