Lithothamnium calcareum is a unique red algae from the North Atlantic. The special feature of this algae is its ability to bind minerals naturally occurring in seawater, especially calcium. Over time, this causes the algae to take on a bright red to white, coral-like appearance.

The ability to bind minerals from seawater results in a high concentration of minerals in the algae, especially of calcium and magnesium. The content of calcium is 32%. It also contains more than 53 trace elements such as chromium, copper, iron, iodine, selenium, manganese, potassium and sulfur, to name a few. This is exactly what makes this raw material so unique as a high quality natural source of calcium for the production of dietary supplements," explains Christian Nega, Director Nutritional & Health Supplements.  "Once processed, the calcium raw material exhibits high bioavailability. This is immensely important, especially for dietary supplements. This makes Lithothamnium calcareum the perfect natural raw material for bone remineralization and acid-base balance.“

MAGNESIA offers this raw material in powder and granule form. The powder (Magnesia 7550000) is characterized by its very good compressibility. This makes it ideal for tablet production. Due to its excellent suspension and dispersion properties, we also recommend it for use in sachets and sticks, where the minerals should be quickly available to the organism.

The granules (Magnesia 8560000) were specially developed for use in capsules. The agglomerates optimize flowability and reduce dust emission during the production process. They achieve better processability and lower material waste at the same time.

Only a small amount of Lithothamnium calcareum as a calcium source in formulations is required to use the following health claims:

A high calcium content, very good bioavailability from a natural source of supply do speak for themselves. Because calcium is of essential importance for the human organism. In addition, there are the further advantages of natural enrichment with magnesium and many trace elements, which this high-quality raw material also offers.
