This product provides 600mg of calcium from a soy amino acid chelate, a form generally considered to have good bioavailability due to being bound to amino acids. However, its significant drawback is the absence of Vitamin D3, which is absolutely essential for calcium absorption and proper utilization in the body. Furthermore, it lacks other crucial cofactors like magnesium or vitamin K2, which are vital for directing calcium to the bones and preventing its deposition in soft tissues. Online reviews are moderate, and without price information, a full value assessment is challenging, but its incomplete formulation is a major detractor.
