Helped me detoxify and lose weight

I've been using this product since I had heard a lot about benefits of glutathione- but glutathione is generally more expensive and I didn't know which form to take... well, NAC is the precursor, so I figured, why not try this first, especially at this price. So- I've gone through maybe 3 bottles now and I've really been impressed with this product. I take a bunch of other ones and switch them up- but I try to make one change at a time to know what's working and what's not. The effects of this product came in an interesting way- so I take these at night figuring my body could probably use this as it repairs and detoxifies at night. What I noticed was that every night I took these, I seemed to lose weight I had always wondered why I couldn't lose (most likely due to toxicity, maybe from just daily exposure of being alive....). I had forgotten to to take them some nights, and those nights, I didn't see the little bit of extra weight loss. Anyway- that was at the beginning- fast forward a few months and my weight is almost always where I feel most balanced. I am not as consistent in taking these as before because I feel more stabilized- but when I know I've eaten something or been exposed to more than usual, I make sure to take them. It was pretty subtle at first, but as long as your body has the ability to convert NAC to glutathione, this seems like a great way to keep toxins flowing out of your system.

It's okay

This is my first time taking this product, and as I'm down to the last of this product, I can't say for sure what benefits I have received from taking it. However, I do like that it's sustain release. I guess maybe I will know the benefits I received once I stop taking it because as of now, I will not reorder it.

NAC slow release

excellent quality from Jarrow, Size is medium, has 2 color sides, packaging was done nicely. NAC has already lots of known benefits so no point mentioning that here. the slow release helps to keep it longer and sustained in the system. I take them alternate days as I found them to be bit harsh on Stomach.

Love the slow release

I take quite a few supplements, so I really like that this NAC is designed to release gradually. NAC can sometimes cause stomach discomfort, so I also like that I’m not getting the entire dose all at once. Not sure if it’s just me, but I was surprised that these have a slightly sweet taste and don’t leave a strong aftertaste.

a bit different compared to regular NAC

It is a bit different compared to regular NAC, like it is slow acting, really slow. Good pricing and pretty easy to take.

The tablet colour is purple looks good.The quality is amazing .The bottle size is medium. The benefits for the liver , lungs and skin take time to show. Thanks

Sustained-Release NAC with Clear Dosage

The tablets are vegan, clearly labeled, and formulated for controlled release, which may help maintain more stable NAC levels compared to immediate-release forms. The 60-tablet bottle offers a practical supply size for regular supplementation. Overall, this is a straightforward sustained-release NAC supplement with transparent dosing and a formulation focused on gradual delivery.

Great NAC option with sustained release

I really like Jarrow Formulas Vegan N-A-C Sustain 600 mg. The sustained-release formula feels gentle and steady, and I like that it’s vegan and easy to take. I’ve been using it regularly as part of my wellness routine and I feel it supports my overall health, especially during busy or stressful periods. Good quality and reliable brand — I would definitely repurchase.

High-quality NAC that actually works

Great quality supplement with clean vegan ingredients and the perfect 600 mg dosage. The sustain-release tablets make a real difference — steady effect without the usual crash you get from regular NAC. It supports detox, lung health, and overall energy. Easy to take, good size tablets, and no weird smell or taste. Reliable brand that delivers what it claims.
