The phrase „green blood“ refers to chlorophyll—the photosynthetic pigment whose molecular architecture bears an extraordinary resemblance to human heme. While chlorophyll exists across terrestrial flora, aquatic microalgae such as chlorella and spirulina deliver its most concentrated and bioavailable matrix on the planet. In this comprehensive review, we investigate the biochemical properties of algae-derived chlorophyll, its heavy metal chelation mechanisms, and its profound benefits for erythropoiesis, detoxification, and immune vitality.

Chlorophyll and Hemoglobin: Biochemical Foundations of „Green Blood“
The chemical structure of the porphyrin ring in chlorophyll is virtually isomorphic to the heme moiety in human hemoglobin. The fundamental structural divergence lies in the coordinating central ion: heme coordinates divalent iron (Fe2+), whereas chlorophyll binds magnesium (Mg2+).
Because of this stereochemical kinship, chlorophyll acts as an erythropoietic adjuvant, stimulating bone marrow reticulocyte output and enhancing cellular oxygen carrying capacity. Regular ingestion of microalgal chlorophyll substantially supports clinical management of iron-deficiency states and chronic fatigue.
Nutritional Profile of Microalgae: Spirulina, Chlorella, and Green Algae as Superfoods
Chlorella (Chlorella vulgaris) boasts the highest documented chlorophyll density in the biosphere, ranging from 3% to 5% of dry biomass. Microalgae also offer over 60% complete protein containing all essential amino acids, rendering them an exceptional nutrient source for plant-based athletes.
Additionally, they supply B-complex vitamins, bioavailable non-heme iron, zinc, and the proprietary Chlorella Growth Factor (CGF)—a nucleotide-peptide complex rich in RNA and DNA that accelerates cellular repair and tissue recovery.
Cellular Detoxification Mechanisms: Heavy Metal Chelation and Liver Protection
The most validated pharmacological attribute of broken-cell-wall chlorella is its sporopollenin-rich cellulosic matrix, which demonstrates affinity for sequestering toxic heavy metals (cadmium, mercury, lead), dioxins, and halogenated pesticides within the intestinal lumen.
These xenobiotics form insoluble chelates that are safely excreted, completely halting enterohepatic recirculation. Simultaneously, chlorophyll induces hepatic Phase II conjugation enzymes, promoting systemic biochemical cleansing.
Impact of Marine Algae on the Immune System, Lipid Metabolism, and Microbiota
Microalgal sulfated polysaccharides act as potent biological response modifiers, stimulating macrophage phagocytosis, activating natural killer (NK) cells, and upregulating secretory IgA along mucosal barriers to ward off microbial pathogens.
Furthermore, marine algae improve lipid metabolism by reducing circulating low-density lipoprotein (LDL) and serum triglycerides. Their soluble fiber matrix acts as an prebiotic substrate that feeds commensal lactic acid bacterial species.
Safe Usage, Microbiological Purity Standards, and Recommended Dosages
Because microalgae naturally bioaccumulate aquatic impurities, selecting certified products cultivated in controlled closed photobioreactors with batch-tested verification against heavy metals, PAHs, and microcystins is critical.
Therapy should commence at low dosages (1–2 g daily) and gradually titrate toward 3–5 g per day, accompanied by copious clean water. For chlorella preparations, verifying a mechanically pulverized cell wall is mandatory to ensure enzymatic nutrient accessibility.
