<qa>  What is the red algae found in three locations in the world?Aquamin is a seaweed-derived mineral source, which is rich in calcium, magnesium and 74 other trace minerals including zinc, iron and selenium. It is produced from the red algae, Lithothamnion Calcareum, which is found in just three locations in the world, including the south-west coast of Ireland and Iceland. During a five-year life span, these algae absorb essential minerals from the sea - this gives Aquamin its unique multimineral content. The algae then break down naturally and settle on the sea bed. These calcified skeletal remains are harvested, washed, dried and milled and provided in a capsule formulation. AquaCal is the capsule form of Aquamin. AquaPT contains green tea and pine bark extract.
