Red algae, particularly the species Lithothamnion, is a natural source of bioavailable minerals, especially calcium and magnesium, which are essential for bone health. Scientific studies have demonstrated that the calcium derived from red algae is readily absorbed by the human body and can help support bone mineral density. For example, a randomized controlled trial published in "The Journal of Nutrition, Health & Aging" (2011) found that supplementation with red algae-derived calcium improved bone mineral density in postmenopausal women compared to a control group. The presence of other trace minerals in red algae may also contribute synergistically to skeletal health. However, while initial evidence is promising in supporting bone health, large-scale, long-term clinical studies are still limited. The mechanism of action is primarily attributed to the high mineral content rather than unique bioactive compounds. Red algae is not a traditional remedy for bone health in most cultures; its use in this context has grown with the popularity of natural, plant-based calcium sources. Overall, scientific evidence supports the use of red algae as a mineral supplement for skeletal health, but further robust clinical research is needed to fully confirm its efficacy.
