Phosphorus is the second most abundant mineral in the human body, with roughly 85 percent found in bones and teeth, where it works alongside calcium to maintain structural integrity. Research suggests that phosphorus plays a central role in cellular function, contributing to the formation of DNA, RNA, and adenosine triphosphate (ATP), the molecule cells rely on for energy production. Studies indicate it also supports healthy muscle contraction and helps maintain the body's acid-base balance. Available in supplemental forms such as calcium phosphate, sodium phosphate, and potassium phosphate, phosphorus is widely present in the diet, and deficiency is uncommon in healthy adults. Ongoing research continues to explore its relationship with kidney health, particularly regarding how the body regulates phosphorus levels over time.
