Safety profile
Safe if uncontaminated; avoid products not tested for microcystins/metals; caution in autoimmune disease and phenylketonuria.

No major interactions are on record for Spirulina at typical doses, but tell your clinician about everything you take.
What Spirulina is

The honest bottom line
Modest metabolic and allergy benefits — but only from a tested, clean source. Contamination is the real risk.
