The evidence in words
Safety profile
Excess phosphate is harmful in kidney disease and may affect bone/vascular health generally. Don't supplement without a reason.
Interactions to respect
Calcium — Calcium and phosphate balance is tightly regulated; imbalance affects bone.
What Phosphorus is
Phosphorus is an essential mineral in bone, DNA/ATP, and cell membranes, abundant in protein foods and processed-food additives.
The honest bottom line
Essential, but you get plenty from food — supplementation is almost never needed, and reducing additive phosphate is the more relevant goal for most people.
