How to Take It
Best taken in the evening
Often taken at night for relaxation and sleep, but absorption is the same anytime — consistency matters most.
On the label
1 - 4mL (1 - 4 full droppers) daily with juice or food to mask the highly concentrated mineral flavor. We recommend starting with 1mL and increasing as needed, ideally spread throughout the day. We also recommend taking Mega-Mag with a large glass of fluid. Taking too much magnesium at once may cause a laxative effect. If this occurs, simply reduce amount per serving.
General guidance based on the ingredients, not a substitute for the label or your doctor.
