Overview
Hawaiian-grown blue green spirulina powder is capsulated here at 470 mg per capsule, with 100 capsules per bottle and a non-GMO, natural label. Spirulina is commonly used as a plant-based protein and nutrient source, matching the protein supplement type listed for this product.
Spirulina is grown in water and harvested as a powder before being encapsulated here, and the Hawaiian sourcing is the specific claim being made rather than a generic spirulina origin. At 470 mg per capsule and 100 capsules per bottle, the total gram amount per bottle is modest compared with loose spirulina powder sold by the tablespoon, which is worth factoring in for anyone used to powder dosing. No flavor is listed, consistent with a capsule delivery meant to avoid spirulina's strong taste.
- 470 mg spirulina per capsule
- 100 capsules per bottle
- Hawaiian-grown sourcing
- Non-GMO, natural formulation
Who it's for
Buyers who want spirulina in capsule form specifically to avoid its taste, and who value Hawaiian sourcing, are the target here. Anyone wanting a higher per-serving gram amount should compare against loose spirulina powder, since 100 capsules at 470 mg each is a smaller total dose than a typical powder scoop.
Strengths and trade-offs
Drawn from this product's published specifications.
- Capsule form avoids spirulina's taste
- Non-GMO, natural labeling
- 470 mg per capsule is a smaller dose than typical powder servings
- No flavor or powder option in this listing
Performance notes
Spirulina's nutritional profile is tied to how it is grown and harvested, and the Hawaiian sourcing named here is the specific origin claim rather than a generic description. Capsule delivery at 470 mg per pill trades a smaller per-serving dose for convenience and no taste, compared with measuring loose powder by the spoonful.
