Chlorella vs Spirulina

Chlorella has a cell wall that binds heavy metals; Spirulina is more protein-dense — same family, different uses.

Both are popular 'greens' supplements: single-celled organisms (Chlorella is green algae, Spirulina is cyanobacteria) marketed for detox, protein, and micronutrients. They overlap on chlorophyll, vitamins, minerals, and protein — but their cell wall structures make them functionally different.

Superfood

Chlorella is a nutrient-dense freshwater green algae containing protein, B vitamins, minerals, and chlorophyll. Evidence for specific health benefits remains limited, though it may support detoxification and overall nutritional intake.

Typical dose: 2-10g daily

When to pick Chlorella

Pick Chlorella for heavy metal binding (its cell wall chelates lead, mercury, cadmium) and fiber. Broken cell wall ('cracked') or micronized forms improve absorption. Dose: 2–5 g/day. Cleanest source matters — contamination is a real risk.

When to pick Spirulina

Pick Spirulina for protein density (60% protein by dry weight), phycocyanin's anti-inflammatory effect, and mild blood pressure lowering. Dose: 1–5 g/day. Verify source — blue-green algae can harbor microcystin toxins if grown in open ponds.

Can you take them together?

Safe to combine — some users take both for broader micronutrient coverage. Third-party testing is crucial for both categories; contaminated products are documented. No drug interactions at supplement doses.
