Overview
•Magnesium L-threonate at 72 mg elemental magnesium per capsule is well below the 350 mg supplemental upper limit and generally well-tolerated in studies.
•Mild gastrointestinal effects such as loose stools or nausea may occur at higher daily intakes but are less common than with other magnesium salts due to lower elemental dose.
•No serious adverse events reported in human trials using 1-2 g of magnesium L-threonate daily.
•May cause drowsiness when taken in the evening; separate intake by 2 hours from antibiotics like tetracyclines or bisphosphonates to avoid reduced absorption.
•Not recommended for pregnant or breastfeeding individuals without medical advice due to limited specific safety data.
