⚠ 4 red flags

  • Origin unclear: the product page says non-EU agriculture, but the lab report names the sample “Bio Spirulina Portugal Pulver”.
  • Total arsenic 0.62 mg/kg, the highest of our six spirulina and chlorella powders (no EU limit for arsenic in supplements; inorganic arsenic was not measured).
  • The sample was sent in by the brand (one 225 g jar, batch L03617): check the batch number on your jar.
  • PAHs and microcystins were not measured in the report (the EU sets PAH limits for food supplements containing spirulina; there is no legal limit for microcystins).
