Biogenesis' Spirulina and Chlorella blend combines two of nature's most prized microalgae, enhanced with over seventy marine plant trace minerals. It contains a wide spectrum of bioactive nutrients including chlorophyll, protein, vitamins including D and B12. minerals, including magnesium which is necessary for normal nerve and muscle functions, and a natural source of iron. Chlorella is more nutrient-dense than spirulina, containing higher levels of chlorophyll, omega-3 fatty acids, iron and may support cleansing and detoxification. It is the only source of Chlorella Growth Factor (CGF). BioGenesis Natural Chlorella is organically grown in the pristine Great Barrier Reef region of northern Australia. Bathed in golden sunshine the Chlorella thrive in the fresh spring water ponds. BioGenesis have developed an innovative advanced energy efficient hydrodynamic growth system that replicates a natural river flow. When harvested they apply an advanced biodynamic technology to gently crack the hard outer cell wall making the nutrients fully available. This Spirulina is naturally grown in California, while the organic marine plant is sustainability harvested from pristine mineral rich Atlantic waters off Iceland.
