What does phosphorus do for us?

Phosphorus binds with calcium to build and maintain healthy teeth and bones. Although calcium and phosphate work together, they also mimic each other; the higher the calcium levels in our blood the lower the phosphate, and vise versa. Phosphorus is also apart of our RNA, DNA, and phospholipids, and helps our cells create ATP (see below). In addition, Phosphorus is needed for cell growth and repairs, helps regulate pH levels in the bloodstream, maintains the kidneys, and assists our bodies in absorbing Vitamin B complex. Lastly, phosphorus may help reduce the effects of multiple sclerosis.

  • RNA (ribonucleic acid) – a nucleic acid that carries instructions from DNA on how to conduct certain process in the cell.
  • DNA (deoxyribonucleic acid) – a nucleic acid that contains genetic instructions and information, is self-replicating, and is present in almost all living organisms
  • Phospholipids – a type of lipid that forms lipid bilayers for all cell membranes. Lipid bilayers are basically the borders of a cell that keeps all the molecules where they need to be.
  • ATP (adenosine triphosphate) – energy created by the cell in a process call glycolysis. Glycolysis is the process that begins the conversion of glucose (sugar) into ATP.
