Product analysis

54 out of 100

Standardized Spirulina 500 mg offers good value for its algae serving. Missing algae details and vitamin A source proportions make precise quality comparisons harder.

AI assessment of the formula, label and price. How scoring works

Nutrient Quality33

Ingredient quality remains uncertain across the formula. The vitamins have named sources, but the algae lacks a specific form description.

Ingredient Transparency70

All amounts are disclosed, along with the vitamin sources. The algae description and vitamin A source proportions are incomplete, limiting precise comparisons.

Value For Money60

The algae serving offers good value. The value of vitamins A and K remains uncertain, so the cost advantage rests on the algae.

Customer Satisfaction83

Customer feedback is very positive. More than a thousand ratings provide a broad view of satisfaction, without establishing health benefits.

Product Focus40

The formula combines algae with two listed vitamins. Benefits for a specific health goal remain uncertain.

78 Performance

Organic Spirulina 2000 mg

Dr. Mercola

A high organic spirulina amount is paired with a small amount of protein, beta-carotene, and iron. It covers the original main ingredient goal, although the supplied label still lacks some source-quality or active-marker details.

57 Performance

Stress Support System

Pure Essence

Organic spirulina is included with a large multi-botanical stress blend, but many active forms remain unspecified. It covers the original main ingredient goal, although the supplied label still lacks some source-quality or active-marker details.

54 Performance

Source of Life Multi-Vitamin & Mineral No Iron

Natures Plus

A meaningful spirulina amount sits inside a broad vitamin, mineral, botanical, and enzyme formula. It covers the original main ingredient goal, although the supplied label still lacks some source-quality or active-marker details.

82 Budget

Organic Spirulina & Astaxanthin

Swanson

The serving cost is not lower, but it is among the closest eligible choices. Certified-organic spirulina nearly doubles the original basic algae amount and adds a small declared astaxanthin dose. It covers the original main ingredient goal, although the supplied label still lacks some source-quality or active-marker details.

78 Budget

Spirulina Micro-Algae 760 mg

Nature's Way

The serving cost is not lower, but it is among the closest eligible choices. A larger spirulina amount is paired with a small amount of protein and beta-carotene in a simple formula. It covers the original main ingredient goal, although the supplied label still lacks some source-quality or active-marker details.

77 Budget

Klamath Shores Blue Green Algae

American Health

The serving cost is not lower, but it is among the closest eligible choices. A simple Klamath Lake blue-green algae serving matches the basic algae amount with no additional active ingredients. Compared with the original, it omits spirulina, so it is not a complete like-for-like replacement.

62 Value

Alkaline Balance

Source Naturals

A small spirulina amount is part of a broad mineral, vegetable, fiber, and botanical formula rather than a focused algae product. The value rests on ingredient breadth or definition rather than a lower serving cost. It covers the original main ingredient goal, although the supplied label still lacks some source-quality or active-marker details.

59 Value

Stem Boost-R

LifeSeasons

Spirulina is paired with vitamin D, blueberry, seaweed, royal jelly, green-tea actives, and carnosine in a broad blend. The value rests on ingredient breadth or definition rather than a lower serving cost. It covers the original main ingredient goal, although the supplied label still lacks some source-quality or active-marker details.

63 Value

EnergyPlus

Pure Essence

A meaningful organic spirulina amount is combined with many adaptogens and mushrooms, with every amount listed. The value rests on ingredient breadth or definition rather than a lower serving cost. It covers the original main ingredient goal, although the supplied label still lacks some source-quality or active-marker details.
