RNA (ribonucleic acid) and DNA (deoxyribonucleic acid) operate at the core of life. Supplemental RNA and DNA promote cellular integrity. They also help maintain healthy skin and other vital tissues. RNA is a nucleic acid that plays an important part in cellular renewal. Adequate amounts of RNA in the body are essential to every aspect of good health and well-being. Supplementation with RNA derived from yeast may support healthy cellular division, replication and repair, as well as promote a healthy immune system. Supplements containing DNA may support chromosomal health and anti-aging efforts.
