This product has definitely helped my dupuytren\'s nodules. I ran out of NAC, and the nodules started to increase in size and tenderness. When I could afford to buy more vitamins, I bought another bottle... and the pain went, and the size of the nodules diminished. I can\'t believe it!! Research online support this. NAC halts the fibroblasts and reduces the growth of the dupuytren\'s cells. Thank you Health Post for making this product available at such a good price. I will not go without again.
