Subsequent, we handled cells with various concentrations of NAD+. When additional for 24 h at eighty µM in HeLa and 400 µM in U2OS cells, NAD+ impaired the incorporation of EdU (Fig. 2a and Extended Information Fig. 1k,l). Furthermore, sixteen µM of NAD+ was enough to reduce fork velocity by ~40% in HeLa cells https://benefits-of-nad-supplemen80134.techionblog.com/31704466/top-does-nad-improve-athletic-performance-secrets
