What it is
Marine algae calcium is a source of calcium derived from certain types of seaweed, specifically Lithothamnion species. The algae are harvested, cleaned, and then processed to extract and purify the calcium carbonate, which is the primary mineral component. This process yields a natural, plant-based calcium ingredient.
Why it's used
Manufacturers add marine algae calcium primarily as a source of calcium, a nutrient. It is often used in fortified foods such as snack bars, plant-based milk alternatives, and dietary supplements. Its neutral taste and ability to blend well make it a versatile fortifier.
Health notes
Marine algae calcium is generally recognized as safe (GRAS) by the FDA for use as a nutrient supplement. It provides calcium, which is essential for bone health. International bodies like JECFA have evaluated calcium compounds. Evidence does not suggest adverse health effects from typical dietary intakes of calcium from food sources.
Allergen info
Marine algae calcium is not derived from any of the 9 FDA major allergens. It does not contain gluten.
