Why is magnesium critical for athletes?

Magnesium is a cofactor in over 300 enzymatic reactions including ATP synthesis, protein synthesis, and muscle contraction. Exercise increases magnesium requirements by 10-20% due to increased utilization and sweat losses.

What is the recommended magnesium intake for athletes?

General recommendation is 400-420 mg/day for men and 310-320 mg/day for women. Athletes may need 10-20% more, targeting 450-500 mg/day for males in heavy training.

What form of magnesium is best absorbed?

Magnesium glycinate and magnesium malate have high bioavailability (~25-30% absorption) and minimal laxative effects. Magnesium oxide has the lowest absorption (~4%). Magnesium threonate has unique brain-penetrating properties.
