Following, we treated cells with various concentrations of NAD+. When added for twenty-four h at eighty µM in HeLa and 400 µM in U2OS cells, NAD+ impaired the incorporation of EdU (Fig. 2a and Extended Data Fig. 1k,l). In addition, 16 µM of NAD+ was ample to lessen fork pace by ~40% in HeLa https://nadforimprovedimmunesyste79023.webbuzzfeed.com/32224788/getting-my-nad-supplementation-and-mitochondrial-health-to-work
