This product is listed as providing an exceptionally high 1000 mg of elemental magnesium from Magnesium Orotate. Magnesium orotate is a specialized form, often investigated for its potential to support cardiovascular health due to the orotic acid component, which plays a role in nucleic acid synthesis. It's typically considered to have good cellular absorption.
However, an elemental magnesium dose of 1000 mg is significantly higher than commonly recommended daily allowances and well above the Tolerable Upper Intake Level for magnesium from supplements for most adults. Such a high dose carries a high risk of adverse effects, primarily strong laxative action and other systemic concerns, making this product potentially problematic for routine use without strict professional guidance.
