"Got stuck in my esophagus and took a few good hours to get dissolve after countless cups of hot tea so becareful not to take this with a fistful of your other supplements. Best to swallow this alone. Product works great though can feel it working"
"I generally rate Jarrows Formula products very high, but I can't do so for this product.
The Jarrows NAC Sustain develops a rotten egg smell after being opened and exposed to air. I complained to Jarrows and I was told the smell is due to the chemical ingredients inherent in the NAC and the product is not spoiled. Jarrows, however, apologized and sent me a replacement bottle. When I opened the replacement bottle there was no smell. Within a week , however, the same unpalatable smell was coming from the the new product.
If it is true that the ingredients inherent in NAC cause this problem, I wonder if NAC produced by other companies also produce the same terrible smell?"
"I take these 2 times a day with NSI's Advan-c and Carlson's D3 softgels. They work great together make sustained improvements as long as you take them. This combination is the best I've found in 20 years of searching."
"NAC is supposed to be one of the things that can detox you from heavy metal. I didn't know if I needed to do this or not....just wanted to try something new. The first few times taking it I got kind of a buzz, like a sudden pick up, maybe similar to having a Red Bull. But after that I haven't noticed a thing. Except maybe my nose seems to be a little clearer. Anyway I believe Jarrow to be a good brand and will finish this bottle."
"This is a precursor for glutathione production. I would say that after taking this I started to feel my body aches and pains disappeared. I use to take a lot of supplements for my joints and did not work.
I settled with that Bone Up,the NSI Bone Booster Complex supplement despite of the daily intake requirements,(finally found a 1 a day calcium supplement from Rainbow Light) no glucosamine,msm,chondroitin etc. Maybe it worked in synergy.
Price is reasonable as well as the no. of caplets. Sometimes I alternate it with Jarrow's Activated Selenium."
