Bio-calcium - because you rely on strong bones throughout your life. Calcium is a vital mineral that adds strength to the bone. 99% of the body's calcium is stored in the skeleton. Scientific studies have shown that a high calcium intake in the early years of life strengthens a women's bones, which is a physical advantage when hormones trigger the natural loss of bone density later in life. Bio-Calcium is intended for those who wish to provide their bones with the recommended amount of calcium and other important nutrients such as vitamin D and K, which are important for effective absorption and utilisation of calcium. After menopause, women lose close to 1% of their bone density a year. In most cases, demineralized, bones cannot be rebuilt, not even by using minerals or hormones. However the combination of calcium, vitamins and minerals in Bio-Calcium, vitamins and minerals in Bio-Calcium +D3 + K offers good protection against loss of bone density. From early childhood until adolescence, our bones gain more strength as a natural development. However around the age of 35, our bones start deteriorating. In the beginning both women and men lose about 0.3% of their bone density every year, but women soon take over. In addition to their age related loss, women lose 0.6% of their bone density after menopause, bringing their total loss of bone mass up to approximately 1% a year. This significant difference between the two sexes is the reason why it is so important for women to get plenty of calcium throughout life. Younger women who need extra calcium to build strong bones often get less calcium than the recommended amount due to the fact that they eat very little. Smoking, drinking, medicine, underweight and lack of physical exercise increases the need for calcium. A healthy diet is always a good way to get plenty of calcium plus the other nutrients that are important for building and maintaining a strong bone mass, but in many cases a supplement is a good investment
