Trimester Safety
Why Canned Spirulina needs extra care in pregnancy
Authoritative pregnancy-specific safety guidance for algae supplements is limited. This is not a seafood mercury question — absence of an FDA fish-chart restriction does not establish that canned spirulina is safe during pregnancy.
Use caution: check product quality and labeling, keep portions modest if your clinician agrees, and discuss supplements with your prenatal care provider.
What to discuss with your clinician
Ask whether canned spirulina fits your prenatal nutrition plan, whether a prenatal vitamin already covers relevant nutrients, and whether a safer alternative is preferable.
💛 Not sure you got it right with Canned Spirulina?
