Directions on the label

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.

This jar provides a flexible, moderate magnesium dose in a liquid format, but it has no clear form advantage over ordinary oral magnesium products.

Scoring criteria

Quantity
100 / 100
The evaluated 200 mg daily magnesium routine is a reasonable maintenance supplementation amount for general adults.
Form
75 / 100
The product provides dissolved seawater-derived ionic magnesium with chloride listed, an ordinary usable form without an established relevant absorption or tolerability advantage over standard oral magnesium.
Convenience
76.5 / 100
Two 1 mL liquid portions daily provide 200 mg magnesium and follow the suggestion to spread the dose through the day.
Label accuracy
100 / 100
The quantified magnesium and mineral lines are internally consistent with the high-confidence FDA database label match.
Purity
75 / 100
The label identifies concentrated seawater as the other ingredient but provides no product-specific evidence supporting a higher or lower purity assessment.
Cofactors
0 / 100
The small amounts of boron, sodium, potassium, sulfate, and chloride do not establish a meaningful complementary clinical benefit beyond the magnesium salt composition.
