Analysis

Spirulina at 1,000 mg supplies the clearest nutritional value. Cordyceps, goji, codonopsis, eleuthero, and schizandra support an energy and resilience theme rather than a focused cognitive mechanism.

Most botanical extracts lack active markers, extraction ratios, and plant-part information. Astragalus and reishi are only 50 mg each, making them minor label additions.

Sixty servings provide better practical value than the smaller version, and active amounts are listed separately. The formula still omits algae purity testing and enough standardization detail to compare potency confidently.

Who is it for
  • Adults seeking spirulina plus adaptogens
  • People who prefer a long-serving-count bottle
  • Users comfortable with broad traditional formulas
Best for
  • General resilience support
  • Daily spirulina use
  • Broad antioxidant supplementation

Pros

  • Provides 1,000 mg spirulina
  • Offers 60 servings
  • Lists all botanical amounts
  • Includes several organic ingredients

Cons

  • Botanical standardization is mostly absent
  • Cordyceps source is poorly defined
  • Astragalus and reishi amounts are small
  • Algae purity testing is not supplied

Warnings

  • No algae-specific contaminant testing is disclosed
  • Astragalus and mushrooms may not suit people using immunosuppressant medicines
  • Schisandra and black pepper can alter medication exposure
  • Red sage may increase bleeding tendency with anticoagulants

Nutrient quality

57 Moderate impact

Organic spirulina is clearly identified, but the many botanical extracts lack ratios, plant parts, or active-marker strengths. Spirulina is meaningful, while cordyceps, astragalus, reishi, and most other extracts are modest.

Ingredient transparency

74 High impact

Every listed botanical has an individual amount. Excipients and daily directions are absent from the supplied data, which leaves some label details uncertain.

Customer satisfaction

65 High impact

The aggregate satisfaction average is favorable, though no detailed feedback is supplied. The substantial volume provides a useful aggregate satisfaction signal.

Value for money

53 Moderate impact

The meaningful spirulina amount helps, but the long undercharacterized blend weakens formula quality. The serving cost is moderate for the broad formula but not compelling for its modest key extracts.

Blue-Green Algae · 1000 mg

A full spirulina amount and several adaptogenic botanicals provide broad antioxidant and immune-modulating support. Human evidence and active-marker disclosure are uneven across the botanical blend.

Black pepper may aid absorption, but most extracts lack standardization and spirulina contaminant testing is not shown. The energy-focused blend offers breadth with inconsistent depth.

Report overview
Blue-Green Algae · 1000 mg OverallScore62
C- Active Ingredient Quality & BioavailabilityC Dose, Safety & Label TransparencyB- Value

The algae is described as organic, but no recognized certification body is identified. The algae portion uses spirulina alone, so cellulose cell-wall processing is not required. The 1000 mg algae serving reaches the high-dose range. No algae-specific contaminant testing is disclosed. The effective algae dose is priced near the collection median.

Eleuthero · 100 mg OverallScore48
F Active Ingredient Quality & BioavailabilityB Dose, Safety & Label TransparencyD+ Value

The extract lacks eleutheroside standardization, an extraction ratio, and plant-part detail. Its clearly stated 100 mg amount reaches the minimum effective extract threshold. A moderate serving cost provides average value, though quality disclosure remains limited.

View ingredientView products
Astragalus · 50 mg OverallScore40
F Active Ingredient Quality & BioavailabilityC- Dose, Safety & Label TransparencyF Value

The generic extract lacks the plant part, species, ratio, and active-marker details needed for a confident quality assessment. The exact 50 mg amount falls below the preferred range for focused astragalus support. Its cost per standard extract amount is high.
