Key differences
Option A
Phosphorus
Phosphorus is the second most abundant mineral in the body (after calcium), with 85% stored in bones and teeth as hydroxyapatite. It is essential for ATP energy production, DNA/RNA structure, cell membrane phospholipids, and acid-base buffering. Deficiency is rare but excess (especially from processed foods) can impair calcium metabolism.
Common forms
- Dicalcium phosphate · 60% bioavailability
- Monopotassium phosphate · 60% bioavailability
Option B
Magnesium
Essential mineral involved in over 300 enzymatic reactions including energy production, protein synthesis, muscle/nerve function, and blood pressure regulation.
Common forms
