Is Spirulina compatible with breastfeeding? Do we have alternatives for Spirulina?


August 5, 2017 (Low Risk)

A shred-like cyanobacteria (blue-green algae) that has been cultivated in Mexico and Africa for centuries, and, is commonly used as food for humans and cattle. It is rich in protein, essential fatty acids, carotenoids, mucilage, mineral salts (Iron) and vitamins (A,B,E).

At latest update, relevant published data on excretion into breast milk were not found.

It is an expensive dietary supplemental product with no evidence on the efficacy for those alleged health benefit attributed by manufacturers.

As a measure of safety, it would be recommended the use of products that are free of heavy metal contamination and other type of toxin-containing algae)
