What it is

Calcium derived from seaweed is a mineral source obtained from certain types of marine algae. The seaweed is processed to extract and concentrate the calcium, often resulting in a powder. This form of calcium is valued for its natural origin.

Why it's used

Manufacturers add calcium derived from seaweed to fortify foods and beverages with calcium, a vital nutrient. It is commonly found in plant-based milk alternatives, such as almond or coconut milk, and in nutritional supplements and drinks. Its function is to increase the calcium content of the product.

Health notes

Calcium derived from seaweed is generally recognized as safe (GRAS) by the FDA when used as a nutrient supplement. It provides calcium, which is essential for bone health. International bodies like JECFA have evaluated calcium compounds for safety. Evidence suggests that calcium from various sources, including seaweed, is well-absorbed and beneficial for bone density when consumed as part of a balanced diet.

Allergen info

Calcium derived from seaweed is not a major allergen. It is not derived from milk, egg, fish, shellfish, tree nuts, peanuts, wheat, soy, or sesame. It does not contain gluten.
