Analysis

The powder delivers 240 mg calcium, 85 mg magnesium, 118 mg potassium, and 300 mg sodium from an 8 g sea-moss serving. Its single-ingredient design is simple and easy to add to food or drinks.

The mineral forms are not identified, so absorption cannot be compared with standardized mineral supplements. More importantly, iodine is not reported even though seaweed can contain variable amounts.

The product is better viewed as a whole-seaweed food supplement than a precise heart-health formula. People who require stable iodine or sodium intake may find the variability unsuitable.

Who is it for
  • Adults seeking a whole-seaweed mineral powder
  • People comfortable with variable natural iodine
  • Users who can account for the sodium content
Best for
  • Adding sea-moss powder to foods
  • Supplemental calcium and magnesium
  • Whole-food mineral intake

Pros

  • Single organic sea-moss ingredient
  • Discloses calcium, magnesium, potassium, and sodium
  • Provides meaningful calcium
  • Powder format is flexible

Cons

  • Iodine amount is not reported
  • Mineral forms are unspecified
  • Sodium amount is substantial
  • Poor fit for precise heart-health supplementation

Warnings

  • Unreported iodine variability may be unsuitable for people with thyroid disease or those taking thyroid medication.
  • The 300 mg sodium serving should be counted by people following a clinician-directed sodium restriction.
  • Sea-moss fiber and minerals may cause bloating or loose stools in sensitive users.

Nutrient quality

45 Lower impact

The food-derived mineral compounds and absorption characteristics are not disclosed. Sodium is moderate, while calcium, magnesium, and potassium are too low for strong targeted support.

.

Ingredient transparency

62 Moderate impact

Mineral amounts are listed, but iodine content and active sea moss constituents are not quantified. The supplied data does not include complete processing and inactive ingredient details.

.

Customer satisfaction

63 Moderate impact

The aggregate satisfaction measure and review volume support a favorable first impression. Missing firsthand feedback leaves repeat complaints and real-world purpose fit uncertain.

.

Value for money

42 Lower impact

The elevated product cost is difficult to justify for modest mineral amounts and uncertain iodine content. Each serving provides weak value for targeted heart or mineral support.

Report overview
Sodium · 300 mg OverallScore78
D Active Ingredient Quality & BioavailabilityA+ Dose, Safety & Label TransparencyA+ Value
The sodium amount aligns well with routine athletic replenishment. Magnesium and potassium add broader mineral coverage, although their forms and the sodium source are not stated. The simple sea-moss powder also delivers favorable value with limited additive concerns.
Calcium · 240 mg OverallScore43
F Active Ingredient Quality & BioavailabilityB+ Dose, Safety & Label TransparencyF Value

Sea moss contributes a moderate calcium amount, but its chemical form and absorption potential are unknown. The powder also supplies magnesium and potassium without disclosing a refined calcium source. Its high serving cost provides poor value for targeted calcium supplementation.

Potassium · 118 mg OverallScore35
F Active Ingredient Quality & BioavailabilityD+ Dose, Safety & Label TransparencyF Value

Sea moss supplies food-derived potassium without identifying its chemical form. The amount is above a standard low capsule dose but remains below the moderate tier. An above-median serving cost provides limited potassium value.
