Calcium is a mineral that is the most in number in our body. Calcium is necessary for maintaining healthy bones, muscle contraction, and supporting cardiovascular function. Our bones are mainly formed in hidroxy apatite form ([Ca3(PO4)2]Ca(OH)2), which makes calcium the most essential mineral in preserving bone density and bone mass.
Calcium, as well other minerals are abundant in our daily food. However, in the process of cooking, these minerals dissolve and decrease in numbers. Calcium minerals, in their elemental state, are normally only 8 to 40% biologically available to humans. For example, if a calcium carbonate supplement contains 500 mg of calcium carbonate, it will only contain 200 mg (or 40%) of elemental calcium. After reaching the age of 35 to 40, the availability of minerals drops to 3 to 5%. Therefore, to meet the daily requirements of minerals we need other source, for example in form of supplements.
Coral calcium is a coral-derived calcium that provides better absorption for calcium in our body. A study performed in Japan attempts to compare absorption rate of calcium between people consuming coral calcium-added crackers and people consuming calcium carbonate-added crackers. The result is measured by calculating increment of urinary calcium excretion. The study states that increment of urinary calcium excretion in people consuming coral-added crackers is greater than in people consuming calcium carbonate-added crackers. It suggests that calcium of coral origin is better absorbed from the intestine than calcium carbonate on the average. Another study states that coral calcium can achieve 95% absorption rate in body. With better absorption, coral calcium provides more benefits to maintain bone health especially for people who requires adequate calcium level, for example : older people, pregnant woman, people in risk of osteoporosis.
Recent observations indicate that in order to increase calcium utilization, our body needs auxiliary substances to improve calcium absorption. Many research state that one of the substances is natural soy isoflavones. Isoflavones are estrogen-like substances that have positive effect on bone and other tissue. Isoflavones are important to support maintaining bone health for they increase calcium absorption in our body and help stimulating bone formation. A research published in American Journal of Clinical Nutrition stated that natural soy isoflavones attenuate bone loss from lumbar spine in perimenopausal women. The results came from isoflavones’ effect to increase bone mineral density and bone mineral content to prevent further bone loss in perimenopausal women.
Other auxiliary substances needed to assist calcium absorption are vitamins. Vitamin D3 (1,25Dihydroxyvitamin D3) , the hormonally active form of vitamin D, is the major stimulator of active intestinal calcium absorption. Another vitamin affecting calcium metabolism is vitamin K. The role of vitamin K in calcium metabolism is stimulating renal calcium absorption to reduce bone loss and increasing maturation of bone tissue.
Aside from calcium itself, our body also needs other minerals to maintain our health. What becomes interesting is, in our body, calcium competes with other minerals for absorption in the intestine. A high intake of one mineral can reduce the absorption of the others. As keen consumers, we must be clever to choose calcium supplement that also contains other minerals with balanced amount.
GOOD LIFE BIOCAL-95, an excellent product from SIMEX PHARMACEUTICAL contains coral calcium as natural-derived calcium with greater absorption rate of calcium (up to 95% absorption of coral calcium) to fulfill calcium requirements. GOOD LIFE BIOCAL-95 also contains natural soy isoflavones, vitamin D3 and vitamin K to increase calcium absorption and well-balanced minerals to support bone tissue. Good Life BIOCAL-95 is an exact calcium supplement that provides more than calcium for your bone.
