Calcium Orotate is a bioavailable form of calcium, bound to orotic acid, a natural compound involved in nucleic acid metabolism. It is known for its enhanced cellular transport, allowing calcium to penetrate cell membranes more efficiently compared to conventional calcium salts like carbonate or citrate.
This property makes it especially effective in bone health, cardiovascular function, and healthy aging formulations. It is widely used in nutraceuticals, dietary supplements, and clinical research targeting osteoporosis and calcium deficiency.
