Supplement
Chlorella
SaveA single-celled green alga rich in chlorophyll, protein, and micronutrients. Studied for heavy-metal binding, immune modulation, and nutrient density.
Quick verdict
A nutrient-dense whole-food supplement. Metal-chelation claims are overstated for oral use, but general nutritional value is reasonable.
Evidence score
A rough internal score reflecting quantity, quality, and consistency of human evidence. Not a clinical recommendation.
What the research shows
Contains complete protein, B12 (though bioavailability is debated), chlorophyll, and growth factor. Animal studies show heavy-metal binding but human chelation data are weak. Small RCTs show modest immune and lipid benefits.
Benefits
- Nutrient-dense whole-food source
- Rich in chlorophyll and growth factor
- Modest immune-modulating effects in small trials
Dosage notes
3–10 g/day of broken-cell-wall chlorella. Start low to assess GI tolerance.
Side effects
- GI discomfort and gas initially
- Green stool
- Photosensitivity (rare)
Who should be cautious
Contamination risk if sourced from polluted waters. May cause GI distress initially. B12 content may include inactive analogues.
What this page cannot tell you
Heavy-metal chelation in vivo is far weaker than marketing suggests. B12 may not be bioavailable. Quality varies enormously by source.
