![]() ![]() Its use has been linked with heart disease, kidney disease and stones and a host of other problems as the excess calcium, mostly unabsorbed by the body, circulates in the blood and can end up depositing along the inner walls of blood vessels and in the kidneys. ![]() This form of calcium is not present in any other type of food we eat and is extremely difficult to absorb. Calcium supplements tend to be made with a synthetically made form derived from mineral rock, calcium carbonate, that is not easily utilised by the body. If calcium levels in the diet are low then calcium stores, such as from the bones, are released in order to fulfill its many and varied essential functions. Excessive consumed calcium is either stored in the bones and soft tissue or deposited in the joints. It is crucial in muscle contraction, nerve signalling, hormonal processes and bone and connective tissue integrity to name but a few things. Calcium makes up over half of the weight of the total mineral content of our body. Other important nutrients for bone health include vitamins D, K2, B complex and magnesium, zinc and phosphorous and fatty acids. The mineral most essential to bone density and therefore strength is calcium. It is possible to be told you have low bone density and never go on to develop full osteoporosis, especially if you adopt a few simple lifestyle and dietary changes. Low bone density and osteoporosis are not necessarily the same thing however. In osteoporosis the normal balance of osteoclast and osteoblast activity is disturbed, the result being a higher ratio of old bone destruction to new bone formation. Normal healthy bones are incredibly strong - some estimates conclude that (weight for weight) bones are stronger than steel! Under normal circumstances, bone tissue is constantly being destroyed and rebuilt by cells called osteoclasts (reabsorb old bone) and osteoblasts (build new bone). Postural abnormalities such as this can lead to difficulty in breathing, severe pain and difficulty in moving around depending on the area of the body worst affected. ![]() In osteoporosis as bone loss increases, the possibility of skeletal deformities also increases, most commonly the spine becomes bent and deformed and height is lost as the body shrinks. It refers to the condition whereby bone mineral density is reduced to below normal levels and continues to decline. This puts the bones at much greater risk from fracture and breaking from minor falls or injuries. The word osteoporosis derives from Greek meaning 'porous bones'. ![]()
