Analysis

The nutrition panel lists 2 g of protein and 3 mg of iron per serving. Those amounts are small and do not support use as a primary protein or iron source.

The product title and comparable serving context indicate 3 g of spirulina, while the ingredient line states 3 mg. Because the supplied data conflict, the actual algae amount cannot be trusted from this label alone.

A loose powder format allows flexible mixing and avoids a large tablet count. The unit discrepancy should be resolved before choosing it for a specific spirulina intake.

Who is it for
  • Powder users willing to verify the label
  • People seeking a mixable spirulina format
Best for
  • Flexible mixing after amount verification
  • Users who can confirm the current packaging

Pros

  • Loose powder allows flexible use
  • Lists protein and iron amounts
  • Simple nutrient profile

Cons

  • Conflicting spirulina units
  • Only 2 g of protein
  • Iron form is not disclosed

Warnings

  • Verify the spirulina amount on the package because the supplied data conflict between 3 g and 3 mg.

Nutrient quality

57 Moderate impact

The listed spirulina amount is far too small to explain the nutrition facts and may be a data error. Until verified, protein, iron, and whole-food potency cannot be assessed confidently.

.

Ingredient transparency

66 High impact

Nutrition amounts are stated, but the spirulina listing appears internally inconsistent. Complete directions, non-active ingredients, iron form, and verification of the spirulina amount are needed.

.

Customer satisfaction

73 High impact

The aggregate rating is strong and supported by a very large feedback volume. Specific experience details are missing, so recurring problems and purpose fit remain uncertain.

.

Value for money

40 Lower impact

The apparent amount error prevents the formula quality from being confirmed. Serving value is weak until the actual spirulina amount is verified.

Report overview
Iron · 3 mg OverallScore51
F Active Ingredient Quality & BioavailabilityB Dose, Safety & Label TransparencyD+ Value

The chemical form of iron is not disclosed, and the loose powder allows flexible mixing but is not a slow-release or liquid iron format. The iron amount is below the effective supplemental range; no qualifying vitamin C, folate, or vitamin B12 support is listed. The cost reflects spirulina rather than a targeted or well-disclosed iron supplement; the serving cost is in the collection’s average band.

89 Performance

Chelated Iron 27 mg

Carlson
<p>It offers more targeted iron support because 27 mg of iron bisglycinate provides a clearly dosed, generally gentle chelated form, compared with the original's 3.00 mg. vitamin C, folate, and vitamin B12 are absent, and unnecessary iron can accumulate, so suitability depends on iron status rather than general wellness use.</p>
88 Performance

Chelated Iron

Solgar
<p>It offers more targeted iron support because 25 mg of iron bisglycinate provides a clearly identified, generally gentle chelated form, compared with the original's 3.00 mg. the simple formula does not include vitamin C, folate, or vitamin B12, so suitability depends on iron status rather than general wellness use.</p>
87 Performance

Vegan True Iron Support

Source Naturals
<p>It offers more targeted iron support because 27 mg of Ferrochel iron bisglycinate is paired with vitamin C, folate, and vitamin B12, compared with the original's 3.00 mg. the iron amount is substantial and may cause constipation or harmful excess when there is no demonstrated need, so suitability depends on iron status rather than general wellness use.</p>
89 Budget

Iron 18 mg

NOW
<p>It is a more economical iron-focused option because the lower serving cost still provides 18 mg of Ferrochel iron bisglycinate provides a focused and clearly dosed chelated form. Compared with the 3.00 mg of food-based or supplemental iron in Pure Hawaiian Spirulina, the formula omits absorption and blood-building cofactors and should not be used without a plausible iron need.</p>
86 Budget

Albion Chelated Ferrochel Iron 18 mg

Swanson Ultra
<p>It is a more economical iron-focused option because the lower serving cost still provides 18 mg of clearly identified TRAACS Ferrochel iron provides a focused chelated form. Compared with the 3.00 mg of food-based or supplemental iron in Pure Hawaiian Spirulina, vitamin C, folate, and vitamin B12 are absent, and iron should be used for a demonstrated need.</p>
88 Budget

Gentle Iron 28 mg

Nature's Bounty
<p>It is a more economical iron-focused option because the lower serving cost still provides 28 mg of ferrous bisglycinate is paired with 60 mg of vitamin C, folate, and vitamin B12. Compared with the 3.00 mg of food-based or supplemental iron in Pure Hawaiian Spirulina, the substantial iron amount is appropriate only when there is a plausible or confirmed need.</p>
83 Value

Iron Complex

NOW
<p>It combines clear dosing and practical value because 27 mg of Ferrochel iron bisglycinate is paired with vitamin C, folate, and vitamin B12. Compared with Pure Hawaiian Spirulina, dong quai and red raspberry add little to iron support, and dong quai may raise bleeding risk with anticoagulant or antiplatelet medicines, but the focused ingredient profile makes its cost easier to assess.</p>
86 Value

High Absorption Iron with Ferrochel 27 mg

Doctor's Best
<p>It combines clear dosing and practical value because 27 mg of Ferrochel supplies a substantial amount of clearly identified chelated iron. Compared with Pure Hawaiian Spirulina, no vitamin C or blood-building cofactors are included, and the dose warrants a confirmed need, but the focused ingredient profile makes its cost easier to assess.</p>
85 Value

Iron Ferrochel Ferrous Bisglycinate Chelate 36 mg

California Gold Nutrition
<p>It combines clear dosing and practical value because 36 mg of ferrous bisglycinate chelate provides a high amount in a focused formula. Compared with Pure Hawaiian Spirulina, vitamin C and blood-building cofactors are absent, and the high dose can cause digestive effects or harmful excess, but the focused ingredient profile makes its cost easier to assess.</p>
