Analysis

The serving provides 375 mg chloride, 150 mg potassium, 100 mg sodium, and 45 mg magnesium. Seawater-derived sodium and named potassium chloride improve source clarity.

These amounts suit lighter activity or everyday electrolyte water. Magnesium is small and sodium is below the range commonly needed during prolonged heavy sweating.

The concentrated liquid is convenient and cost-effective when measured accurately. Heart-health use should be framed as electrolyte support rather than a substitute for broader cardiovascular care.

Who is it for
  • Adults with light or moderate sweat losses
  • People seeking a simple electrolyte concentrate
  • Users who prefer liquid dosing
Best for
  • Everyday electrolyte water
  • Short workouts
  • Low-cost chloride and potassium

Pros

  • Names seawater sodium and potassium chloride
  • Provides useful chloride
  • Low serving cost

Cons

  • Sodium is low for heavy sweat loss
  • Magnesium is modest
  • Not a comprehensive endurance formula

Warnings

  • The sodium amount is insufficient as sole replacement during prolonged heavy sweating or heat exposure.
  • Kidney impairment or potassium-raising medicines require individualized guidance.
  • Measure and dilute the concentrate according to label directions.

Nutrient quality

67 High impact

Potassium chloride and seawater sodium provide recognizable sources, but other forms are less clear. Modest magnesium, sodium, and potassium limit the depth of endurance support.

Ingredient transparency

75 High impact

Every active mineral has a stated amount and no blend hides the quantities. Branded mineral terms, absent inactive ingredients, and incomplete use directions reduce clarity.

Customer satisfaction

70 High impact

Aggregate customer metrics indicate strong satisfaction from a large sample. Missing feedback details prevent judging repeated complaints or whether experiences match the intended use.

Value for money

69 High impact

The low serving cost supports light hydration use. Modest electrolyte amounts weaken value for endurance or heavy-sweat replacement.

C+ Goal FitC Strength of SupportD- CoverageA- Formula Quality
Magnesium · 45 mg

Potassium chloride provides a moderate electrolyte amount for sodium-potassium balance. The liquid format is clearly designed for exercise hydration.

The amount is not high enough for broad potassium repletion, and chloride lacks the buffering advantages of citrate. No magnesium or other cardiovascular active broadens the formula.

Report overview
A+ Active Ingredient Quality & BioavailabilityA- Dose, Safety & Label TransparencyB+ Value

Ionic trace minerals provide chloride in a concentrated mineral complex. The chloride serving provides a meaningful amount for electrolyte replenishment. The cost per serving offers good value for the meaningful chloride amount.

Sodium (Seawater) · 100 mg OverallScore84
A Active Ingredient Quality & BioavailabilityC+ Dose, Safety & Label TransparencyA+ Value

Seawater-derived sodium and ionic trace minerals give the formula a clear mineral-quality advantage. Potassium and magnesium broaden coverage, but the sodium amount is too low for substantial sweat replacement. The concentrated liquid is economical and contains no disclosed sugar or artificial color.

A- Active Ingredient Quality & BioavailabilityC Dose, Safety & Label TransparencyB+ Value

The liquid format and ionic trace-mineral source support efficient delivery. Its 20 mg sulfate amount is a lower maintenance dose, even though the individual electrolyte amounts are transparent. The serving cost remains favorable.
