Spirulina is a cyanobacteria that has been commonly recommended by clinicians as a good source of antioxidants. However, it has rapidly fallen out of favor since 2017 due to the high amounts of the significant neurotoxin BMAA (a natural byproduct of the organism.)

Ethnobotanist Paul Cox has done extensive research on the strong association with BMAA levels in an organism and the risk of development of Alzheimer’s disease and possibly ALS.

In addition to possible significant neurotoxicity, experts report infrequent side effects of dizziness, constipation, thirst, stomach distress, and itchiness. It is also said to be contraindicated in hyperparathyroid disease
