Our calcium is obtained from the sustainable extraction of calcified Atlantic Lithothamnium red algae. Due to its organic structure, our phytocalcium has particularly good bioavailability.
Atlantic Lithothamnium red algae has an exceptionally high concentration of naturally bound calcium (32%). The calcium is present in the form of calcium carbonate and is embedded in a mineral complex with magnesium. During its growth, the algae absorb these from the seawater and form their cell structures. After dying, the algae body calcifies into a finely porous, skeleton-like structure and sediments separately from the younger algae on the seabed of the Atlantic Ocean. In various locations, these sediments can eventually be sustainably harvested.
Our phyto-calcium consists of 100% natural calcified Lithothamnium calcareum from Iceland, which is harvested, cleaned and milled according to HACCP and ISO 22000:2018 standards, ensuring processing with minimal heavy metal and microbiological values, resulting in a red algae powder of maximum purity and compatibility. As a result, the heavy metal values, despite the origin from the seabed, are significantly below the European limits.
For the capsule shells we use custom-made HPMC capsules that, unlike most other HPMC and pullulan capsules on the market, are 100% free from controversial additives such as carrageenans and PEG. We then package this product in environmentally friendly amber glass.
