Synopsis

Source of validity: Scientific
Rating (out of 5): 3

Molluscs, such as oysters, clams, and mussels, are recognized sources of dietary calcium, which is essential for bone health and the prevention of calcium deficiency. The calcium content in molluscs varies depending on the species and preparation method, but some, especially those consumed with their shells (e.g., ground shell powders), can provide significant amounts of bioavailable calcium. Scientific studies have analyzed the nutrient profiles of various molluscs and found that their flesh and shells can be a valuable source of calcium, particularly in communities with limited access to dairy products or other traditional calcium-rich foods.

Moreover, calcium supplements derived from mollusc shells (such as oyster shell calcium) are commercially available and have been used in clinical and nutritional contexts to support calcium intake. There is evidence that calcium from mollusc shells is bioavailable, though the absorption rates may be somewhat lower than those from purified calcium carbonate. The use of mollusc-derived calcium is generally considered safe, though concerns about contaminants such as heavy metals in some shell sources have been raised.

In summary, the use of molluscs and their derivatives to address calcium deficiency has a basis in scientific evidence, particularly for populations seeking alternative sources of dietary calcium. However, it is not the most widely recommended or primary source when compared to dairy or pharmaceutical-grade supplements, which explains the moderate rating of 3.
