Synopsis
Source of validity: Scientific
Rating (out of 5): 3
Lithothamnion is a genus of red marine algae known for its high mineral content, particularly calcium and magnesium. It is used in dietary supplements as a natural source of calcium, especially for those seeking plant-based or vegan alternatives to traditional calcium supplements derived from dairy or rocks (e.g., calcium carbonate). The use of Lithothamnion for supporting or treating calcium deficiency has a scientific basis: several studies have demonstrated that its calcium is bioavailable, meaning it can be efficiently absorbed and utilized by the human body. For example, a randomized controlled trial by Walsh et al. (2015) found that calcium derived from Lithothamnion was as effective as calcium carbonate in maintaining bone health markers in postmenopausal women. Additionally, Lithothamnion provides other trace minerals that may contribute synergistically to bone health. However, while there are some scientific studies supporting Lithothamnion's efficacy as a calcium supplement, large-scale and long-term studies are still limited, and most evidence comes from small clinical trials or in vitro studies. Thus, while its use is scientifically justified and it is commonly used for this purpose, the overall evidence strength is moderate rather than robust.
