Question 1

Who are Biogenic Minerals?

Accepted Answer

Established in 2014, Biogenic Minerals (Icecal ehf.) is an Icelandic company dedicated to the recycling of discarded quahog shells and calcareous algae into a sustainable source of calcium. With a team boasting many decades of experience in valorizing ocean resources, we have set our mission as the supply of affordably priced sustainable calcium for customers with an ecologically friendly approach and interest in wellness.

Question 2

How is seaweed calcium different from other calcium sources?

Accepted Answer

Seaweed calcium differs from traditional calcium carbonate or calcium citrate because it comes from whole food algae, not rocks. It provides a multi-mineral complex (calcium, magnesium, and over 70 trace minerals), is easier for the body to absorb, and is gentle on digestion.

Question 3

What is algae-based calcium?

Accepted Answer

Algae-based calcium is a natural mineral source harvested from red marine algae, primarily Lithothamnion species. As the algae grow, they absorb calcium, magnesium, and trace minerals from seawater, creating a plant-based, highly bioavailable form of calcium.

Question 4

What is Algae Calcium?

Accepted Answer

Algae calcium is another term for algae-based calcium — a plant-sourced form of calcium derived from marine algae. It is sustainable, natural, and designed to support bone, joint, and overall mineral health.

Question 5

What is Seaweed Calcium?

Accepted Answer

Seaweed calcium is calcium naturally concentrated in seaweed or marine algae. Unlike synthetic or rock-based supplements, it offers a balanced mineral profile and is considered more bioavailable.

Question 6

Is algae, Lithothamnion-derived calcium, vegan and vegetarian friendly?

Accepted Answer

Yes. Since it is sourced entirely from marine plants (red algae), it is 100% vegan and vegetarian friendly, with no animal ingredients.

Question 7

What is the best form of calcium for bone health?

Accepted Answer

Research suggests that food-derived calcium, such as algae-based calcium, may be better absorbed and better tolerated than traditional calcium salts. Combined with vitamin D, magnesium, and lifestyle factors, algae-based calcium is considered one of the best options for supporting bone density and strength.

Question 8

What does “organic calcium” mean?

Accepted Answer

“Organic calcium” does not mean it is certified organic farming. In nutrition, the term refers to calcium that is naturally bound within a plant or food matrix, rather than inorganic mineral salts like limestone. Algae-based calcium is a good example of an “organic” calcium source because it is absorbed and utilized more effectively by the body.

Question 9

In what final products can Lithothamnion be used (food-grade)?

Accepted Answer

Food-grade Lithothamnion can be used in fortified plant-based beverages (such as oat, soy, or almond milk), dairy products, bakery goods, cereals, and functional foods where added calcium and trace minerals are desired.

Question 10

In what final products can Lithothamnion be used (nutraceutical-grade)?

Accepted Answer

Nutraceutical-grade Lithothamnion is commonly used in dietary supplements such as capsules, tablets, and powders. It is formulated for bone health, joint support, and overall mineral supplementation.

Question 11

Why is Lithothamnion preferred over conventional calcium carbonate?

Accepted Answer

Unlike conventional calcium carbonate (typically mined from rock), Lithothamnion-derived calcium is plant-based, renewable, and naturally contains a broad spectrum of trace minerals. It is generally more bioavailable, better tolerated in digestion, and aligns with consumer demand for clean-label, plant-based, and sustainable ingredients.

Question 12

How much lithothamnion is usually used in a typical carton of alternative milk in the market?

Accepted Answer

A typical 1-liter carton of plant-based milk contains approximately 0.003 g – 0.004 g of Lithothamnion-derived calcium.

Question 13

What form does Lithothamnion have?

Accepted Answer

Lithothamnion is processed into an off-white powder, making it easy to incorporate into both food and supplement formulations.
