Calcium is the most abundant mineral in the human body, comprising over 1.5% of the total body weight. About 99% of the body's calcium is found in the bones, with 1% occurring in the soft tissues. Calcium absorption is vitally dependent upon vitamin D. Calcium is involved in the structural formation of bones and teeth. It is also needed for 'normal' communication amongst nerve cells, for blood clotting, wound healing and for muscle contraction. If there is not enough calcium consumed daily, the body will take it from the bones to help it perform vital functions. Adults only gets 50% of the calcium they need from the diet. Calcium has been used to treat a variety of disorders. Its primary use is the promotion of healthy bones and teeth. Calcium has also been shown to be beneficial in protection from osteoporosis which is usually related to post-menopausal women. Taking one tablet of Bio-Calcium + D3 + K (equivalent to 500 mg calcium) per day is recommended for general well-being and two tablets (equivalent to 1000 mg) per day has been shown to give a therapeutic benefit. There are many calcium preparations on the market, however, Bio-Calcium is perfectly balanced to give optimum absorption. Bio-Calcium contains vitamins D and K which promote the absorption of calcium. Without vitamin D, the body cannot absorb calcium. There are many scientific papers that show the beneficial effects of Bio-Calcium, particularly in its use as a mineral for maintaining bones and teeth, helping prevent progressive bone loss and osteoporosis. Advice should be taken from a doctor, before taking with some diuretic drugs (especially thiazides) which increase the calcium level of the blood. Patients who are prescribed tetracycline antibiotics should take these a few hours apart from their calcium supplement. Sugar, Yeast, Dairy and Gluten free. Suitable for Vegetarians
