Recommended Use
Suggested use: Take 1-4 mL (0.8 tsp) daily with juice or food to mask the highly concentrated mineral flavor and follow with a large glass of fluid. We recommend starting with 1 mL and increasing as needed, ideally spread throughout the day. Taking too much magnesium at once may cause a laxative effect. If this occurs, simply reduce amount per serving.
Warnings
Taking too much magnesium at once may cause a laxative effect. If this occurs, simply reduce amount per serving.
