What is Calcareous Algae?
Calcareous Algae, scientifically known as Lithothamnium calcareum, is a marine-derived mineral source composed primarily of calcium and magnesium carbonates. It is classified as a mineral ingredient and is commonly incorporated into dietary supplements. This ingredient is frequently used in products marketed for joint health, bone support, and mineral supplementation. Its natural origin from red algae deposits makes it a preferred choice for formulators seeking plant-based mineral sources. Calcareous Algae is often found in formulations alongside other minerals and botanicals aimed at overall skeletal wellness.
