ĦBuild Better Health with Cellular Build! -------------------------------------------------------------------------------- Description: Nucleotides - the building blocks of DNA and RNA - are vitally important to the growth and renewal of the body's cells. The body manufactures some nucleotides, reuses old ones or obtains them through the diet. New NSP Cellular Build™ provides dietary sources of nucleotides to help reduce the time and energy required for cell multiplication. A ready supply of nucleotides is particularly important for the immune system and the intestinal system, where rapid cell division is necessary to renew the lining of the gastrointestinal tract.
