Blackmores Celloids Professional Silica Calcium Fluoride Tablets is a calcium re-organiser in the body and is an essential component in the production of connective tissues. In the early stages of bone development, silica is intimately involved in the incorporation of calcium and phosphate into bone apatite, helping to increase the rate of mineralisation of new bone. It acts as a nucleating agent or seed crystal around which bone mineralisation progresses and thus is necessary for the initiation of bone growth (for example during foetal development and bone repair). Silica is also involved in the growth of cartilage. This bottle contains 84 tablets.
