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.

Scoring criteria

Quantity
100 / 100
Two milliliters provide approximately 200 mg of magnesium, which is a reasonable general supplemental maintenance amount.
Form
65 / 100
The product is a liquid concentrated-seawater preparation with quantified chloride, but the exact magnesium salt and its applicable absorption or tolerability properties are not explicitly established.
Convenience
100 / 100
The smallest labelled routine reaching a reasonable supplemental amount is 2 mL daily, equivalent to half of the 4 mL serving and one administration.
Label accuracy
100 / 100
The quantified panel and directions are consistent with the high-confidence FDA label match.
Purity
75 / 100
No product-specific contaminant or additive defect is supplied, but the stated quality claims lack named certification details.
Cofactors
50 / 100
The declared 1.5 mg of boron has a plausible complementary bone-related role, but added clinical benefit is uncertain.
