Magnesium Glycinate Supplementation in Children

Recommended Dosing

The American Academy of Pediatrics recommends a standard supplementation dose of approximately 5-6 mg/kg/day of elemental magnesium for children, translating to a starting dose of 100-130 mg elemental magnesium daily for an average-weight 6-year-old 1, 2
The maximum safe dose of elemental magnesium for a 6-year-old child is 110-130 mg per day to minimize gastrointestinal side effects, according to the American Academy of Pediatrics 1

Magnesium glycinate (bisglycinate) is preferred over other forms due to superior gastrointestinal tolerance, as recommended by the American Academy of Pediatrics 2, 3

The American Academy of Pediatrics suggests administering magnesium glycinate 1-2 hours before bedtime if using for sleep support 2
Gastrointestinal effects (diarrhea, abdominal cramping) are the primary concern at higher doses, as noted by the American Academy of Pediatrics 1, 3

The American Academy of Pediatrics recommends assessing renal function before initiating magnesium supplementation, as magnesium is primarily renally excreted and contraindicated in severe renal impairment 1, 3
Monitoring for hypermagnesemia signs (muscle weakness, hypotension, or bradycardia) is essential, as advised by the American Academy of Pediatrics 3
Watching for gastrointestinal side effects is crucial, as they are the most common adverse effects, according to the American Academy of Pediatrics 3

The American Academy of Pediatrics advises against using magnesium glycinate in children with severe renal impairment, complete heart block or severe cardiac conduction abnormalities, or active gastrointestinal obstruction 1, 2, 3, 4

The American Academy of Pediatrics notes that the 110-130 mg daily maximum applies specifically to routine oral supplementation in otherwise healthy children, whereas higher doses may be used in emergency/acute care settings 1, 4, 5
