How evidence grades work
Each grade reflects the strength and consistency of published human evidence — not marketing claims. Grades are based on study count, design quality, effect size, consistency, and recency.
- Strong
- Multiple RCTs, consistent direction, adequate effect size
- Moderate
- Some RCTs or consistent observational data in humans
- Preliminary / Mixed
- Animal or in-vitro only, or conflicting human data
- Traditional / Theoretical
- Traditional use only; no controlled human trials

What the evidence actually shows
This table contains 1 structured source, including 0 human evidence sources; 0 are human trials. A reliable participant total cannot be calculated because sample size is not consistently structured in the cited sources. Source-to-conclusion relationships are not classified in this structured set, so consistency is not yet classifiable.
Profile-wide evidence grade: see the profile grade above · Confidence: not separately assigned
What would change our conclusion?
Larger, well-controlled human trials using comparable populations, doses, preparations, and clinically meaningful outcomes could materially strengthen or weaken this conclusion. Replication in a different population or a high-quality synthesis resolving current disagreement could also materially change confidence.

Compound profile context
How to interpret Spirulina
Spirulina compound profile with evidence context, key research topics, source notes, safety context, and references presented in an evidence-first format. Use this compound profile to understand mechanism, evidence quality, and practical safety context before comparing products or building a stack. A biochemical pathway connection can be useful for discovery, but it is not the same as proven benefit in humans.
When reviewing Spirulina, separate the active molecule from the product category around it. Dose form, absorption, extract standardization, medication interactions, and individual sensitivity can change the real-world risk-benefit picture.
For supplement planning, avoid combining multiple compounds with overlapping sedating, stimulating, serotonergic, blood-pressure, anticoagulant, or liver-metabolism effects unless a qualified clinician has reviewed the context.
