Research Summary
Most people obtain adequate phosphorus from dietary sources including dairy, meat, fish, and grains, making supplementation rarely necessary. Research indicates that maintaining proper calcium-to-phosphorus ratios is more important than absolute intake levels. Deficiency is uncommon in developed nations but may occur in certain medical conditions or with prolonged use of phosphate-binding medications.
