Aquamin constitutes a unique multi-mineral complex produced from a marine seaweed which contains calcium, potassium and other minerals. It is extracted from the red marine alga Lithothamnion calacareum which settles on the not polluted seabed along the western Irish shore and near Island. During its life cycle (4-5 years) this seaweed species absorbs minerals from sea water. Subsequently, when it is almost completely calcified, the organic tissue is necrotised and the calcified shell goes to the bottom. In connection with Aquamin it is important to know that the ocean vegetation is 10-20 times richer in minerals than the terrestrial vegetation and that the sea water nutrient ratio is equal to that of human plasma. Besides calcium and potassium, Aquamin contains 72 additional important trace elements such as zinc, iron and some others.
