The powder and prepared drink can use different form descriptions
Natural Vitality’s current Original Unflavored page, branded MAXCALM, describes citric acid and magnesium carbonate forming ionic magnesium citrate with water. This explains why a dry-ingredient list can mention carbonate while the prepared drink is described as citrate. The reaction is not evidence of an immediate calming effect. [1]
Use the amount on your own container
The inspected page describes 350 mg magnesium per serving. That does not establish the serving or formula for every flavor, gummy, stick pack or regional version. ODS sets the adult upper limit for magnesium from supplements and medicines at 350 mg daily; food magnesium is excluded from that limit. A label serving is not an individualized requirement. [1][2]
The name does not diagnose what you need
Imagine taking another magnesium supplement alongside the powder. Add the elemental amounts before assessing intake. Magnesium has normal nerve and muscle roles, but persistent anxiety or sleep problems should not be assumed to reflect deficiency; diarrhea and kidney-related risks also remain relevant. [2]
