High manganese doses (100 mg/kg) reduce magnesium absorption and plasma levels; optimal ratio is 10-50 mg/kg

Avoid excessive manganese supplementation when taking magnesium; maintain proper dosing ratio

Potassium Caution

K, Mg, and Ca work in tandem for neuromuscular function and cardiac rhythm; imbalances dangerous

Avoid supplementing potassium unless medically supervised; maintain electrolyte balance

Magnesium is a critical cofactor for all enzymes that activate and metabolize vitamin D in the liver and kidneys. Adequate magnesium is REQUIRED for optimal vitamin D function. Bidirectional: Vitamin D aids magnesium absorption.

Ensure adequate magnesium intake (RDA: 310-420 mg/day) when supplementing vitamin D. Consider combined Mg+D3 supplementation for synergistic bone and cardiovascular benefits.
