The Importance of Calcium
Calcium is a mineral that helps build strong bones and teeth and regulates muscle contraction. / Milk and dairy products have long been held as an important source of calcium. /Calcium can continue strengthening your bones / until the age of 20 to 25 when peak bone mass is reached. / After this point, your bones can only maintain or lose their density / and grow weaker as a natural part of the ageing process. / Inadequate dietary calcium intake before this age / can increase the risk of brittle bone disease, / as calcium is drawn from the bones as a reserve. /
