Overall: Recommended! Great NAC product for supporting immune function and general wellness the bottle packaging is fine and the safety seals are doing the job. Worked for us! Cheers

These vitamins taste and smell absolutely awful. Couldn't take them because they made my stomach bloated really badly and my gas... the way it made my burps and farts smell was worse than sour stomach. Don't really recommend these specific ones.

BOTTOM LINE: 1. I recommend this PRISTINE-N-Acetyl L-Cysteine NAC 600MG 60 Day Supply. 2. The current price of ~$13 is reasonable. LIKES: - 660mg of NAC is awesome. - Good capsules are easy to swallow. - Other ingredients are acceptable. - Made in the USA. DISLIKES: - None.

I can't speak to the efficacy (or not) of these capsules as I'm only a few days in. I was a little hesitant to start taking them as the similarly named "NAD+" makes me flush. As far as I can tell, the "N" in NAC denotes acetylation rather than Nicotinamide (Niacin). So far I haven't experienced any flushing or prickly heat.

This N-Acetyl L-Cysteine (NAC) supplement is aimed at supporting immune health, lung function, and liver health. It is particularly beneficial for those looking to boost their antioxidant intake and improve overall well-being. It's made in the USA, non-GMO, GMP-compliant, free of gluten, lactose, soy. Each serving (1 capsule) contains 600mg of NAC, providing a substantial dose to support your health needs. NAC is known for its ability to boost glutathione levels, a key antioxidant that helps strengthen the immune system. It is beneficial for maintaining healthy lung function, making it a great choice for those with respiratory concerns. NAC aids in detoxifying the liver, breaking down and elimination of toxins, helping to remove harmful substances from the body. NAC has been shown to have positive effects on mood and mental health, making it a valuable addition to your daily routine. NAC is a precursor to glutathione; glutathione is known as the master antioxidant, produced naturally in the body. By boosting glutathione levels, it helps combat free radicals and reduce oxidative stress. NAC and glutathione are closely related, but they serve different roles in the body. NAC is an amino acid derivative and a precursor to glutathione. It helps increase glutathione levels in the body. NAC is more stable and bioavailable compared to glutathione, making it easier for the body to absorb. NAC can help improve lung function and reduce symptoms of chronic respiratory conditions. NAC has mucolytic properties, meaning it can help thin mucus, which is beneficial for respiratory health.

I've tried a few different kinds of glutathione supplements, including straight glutathione (lipsomal), s-acetyl glutathione, N-acetyl cysteine (with and without glycine). Supposedly your body can't absorb glutathione and must break it down into precursor aminos. But once that happens, I don't know what the difference is between taking those precursors individually and taking glutathione. NAC+glycine is the form that's been studied the most, but considering how much glycine we have in our diet, why not just take NAC? To be honest, I can't feel much of a difference between these products. They all - including this one - seem to produce a light relaxing effect. I use this at night to help with sleeping, but also with the hopes that it's reducing aging to some degree. I've tasted all the powders and this one is much more acidic than the others. It's actually the most acidic amino acid I've ever tasted (versus acetyl-L tyrosine or carnitine). I'm wondering if the acetic acid is fully reacted with the cysteine, but I'd need a lab to verify that. Despite the acid, I had no indigestion or upset stomach with this. It probably has a low risk of any real downsides.

Pristine's seems to really have a pretty good company going; they provide the lab test results from third-party testing of their materials, and they print the address of their manufacturing facility (which, amazingly, is in the USA!) on the bottle label alongside the ingredients list and explanations of the functions of those ingredients--a nice addition. Not all companies do that. The bottle was shrink wrapped and came with a foil tamper-evident safety seal, and no odd odors or colors in the bottle. Everything seems like good quality, and coming from a company specializing in research and supplements involved with extending healthspan, so they can concentrate on just that niche market. $13 for a two month supply seems pretty reasonable to me.
