A nucleotide is regarded as the basic building block of DNA and RNA. Nucleotides are critical for digestive health as they are essential to creating new cells, improving the efficiency of cellular repair, and helping maintain a healthy intestinal tract. Nucleotides may also have a beneficial effect on the intestinal microflora, stimulating the growth of beneficial bacteria and inhibiting pathogens. Harmful species of bacteria are suppressed as nucleotides increase the amount of helpful microflora competing for resources in the digestive system.
