After purchasing this product and doing more research, I discovered that there really is no reason to take n-a-c in a sustained form, and that a sustained release is perfectly achievable by administration with food.
This contains gum, true. It contains xylitol, true. They resemble chicklets. But if you bite into the hard shell and look at the composition inside, you'll notice that these two components are not chemically bonded. The product consists of an extremely rough mixture of very large, unrefined xylitol crystals and gum. As soon as any kind of moisture is added, the xylitol washes away instantly. Of dubious quality.
After purchasing this and taking it for its well-documented nepho-protective effects, I noticed my exercise endurance and recovery increasing significantly. I performed some research to explain this and discovered that it does, indeed, improve endurance and exercise capacity. I also discovered that chemical cysteine is frequently manufactured from human hair in China -- raising questions about cannibalism. Overall, an excellent addition to my regimen.
I take this for wasting issues in connection with a chronic disease. One cup in the morning and one cup in the evening has increased my strength and endurance throughout the day.
