Algae Calcium from Lithothamnion Algae

Calcareous Lithothamnion (algae calcium) is a natural marine source of calcium, magnesium, and other trace minerals — a better choice for calcium fortification, as shown by research.

Arctica Islandica

A natural, marine source of sustainable calcium from ocean quahog shells (Arctica Islandica). A better choice for the environmentally conscious customer.

Algae Calcium 
Lithothamnion Calcareum

Algae are a diverse group of aquatic organisms found in various marine and freshwater environments. Some species of algae can absorb and accumulate minerals, including calcium, from their environment.

Algae calcium is typically made from calcified remnants of these marine algae, such as Lithothamnion Calcareum, a type of red algae found in the Atlantic Ocean. The calcified remains of the algae are harvested sustainably, washed, and dried before being milled into a fine powder that can be used to fortify foods and drinks and as a dietary supplement.

One of the added benefits of calcium from algae, besides being a natural source of calcium, is that they also contain other minerals and trace elements, such as magnesium and boron, that are important for bone health.


Algae calcium supplements are a high-quality alternative to traditional calcium supplements, such as calcium carbonate or calcium citrate, where the required material is often extracted from non-renewable sources with negative environmental impacts. 

Several studies have suggested that calcium supplements derived from algae may have advantages over other forms of calcium supplements in terms of bioavailability, its ability to support bone health, and even restore bone density.

Quahog Clam Shells
Arctica Islandica

The shells of the ocean quahog (Arctica Islandica) are composed mainly of calcium carbonate, commonly found in seashells and other skeletal structures of marine animals, with trace amounts of magnesium, strontium, and other minerals.

Since calcium is an essential mineral for bone health, muscle function, and other critical bodily functions. The high percentage of calcium carbonate in the quahog clam shell makes it a valuable source of calcium for human consumption, while magnesium and strontium are also essential minerals for overall human health.

While the absorbance of calcium carbonate from limerock is normally small, the unique mineral composition and crystal structure of the calcium mineral in quahog clam shells helps the human body to absorb and use the calcium. Supplementing with finely milled quahog clam shells may therefore help support bone health by providing a source of calcium that the body can easily absorb.

Our quahog clam shells are also sourced sustainably, as confirmed by the Solar Impulse  Foundation. This makes our marine calcium a high-quality alternative to traditional calcium supplements, usually derived from non-renewable resources with a higher environmental impact.
