Spirulina
Arthrospira platensis
The blue-green algae that fed Aztec markets — protein-dense, mineral-bright.
Full profile →- Origin
Alkaline lakes; cultivated
- Format
Powder or tablet
- Best time
Morning, with food
What it is
Spirulina is a microscopic spiral cyanobacterium harvested from alkaline waters. It was a staple food of the Aztecs at Lake Texcoco.
How it works
Phycocyanin scavenges reactive oxygen species. Iron is delivered in a highly bioavailable form. The chlorophyll content supports detoxification pathways.
The protocol
3–5 g daily, in powder or tablet form, with a meal.
Sourcing
Third-party tested for microcystins, heavy metals, and bacterial contamination. Cultivated in controlled freshwater is preferable to open-lake harvest.
Honest caution
Source matters — only buy spirulina tested for microcystins and heavy metals. Avoid if you have phenylketonuria (PKU).
