inorganic sources of Oyster shell
eq. to elemental calcium…….500 mg

Absorption Calcium carbonate: About 15-25% gets absorbed in the GI tract. Converted to calcium chloride by gastric acid. Vitamin D well-absorbed in the GI tract in the presence of bile.
Distribution The vast majority of total body calcium (>99%) is present in the skeleton as calcium-phosphate complexes, primarily as hydroxyapatite. Vitamin D binds to receptors located throughout the body.
Excretion Calcium leaves body in faeces mainly. vitamin D and metabolites are mainly excreted in the bile and faeces.
During the active phase of growth and development of the skeleton
I.e. childhood, adolescence and early adulthood; pregnancy and lactation
Prevention and treatment of osteoporosis, particularly in women after menopause and elderly men;

- Drug Interaction
Calcium can decrease the absorption of other drugs such as tetracycline antibiotics (e.g., doxycycline, minocycline), bisphosphonates (e.g., alendronate), estramustine, levothyroxine, and quinolone antibiotics (e.g., ciprofloxacin, levofloxacin). Also, certain medications can decrease the absorption of vitamin D (bile acid sequestrants such as cholestyramine/colestipol, mineral oil, orlistat). Therefore, separate your doses of these medications as far as possible from your doses of calcium/vitamin D. Ask your doctor or pharmacist about how long you should wait between doses and for help finding a dosing schedule that will work with all your medications. Vitamin D is very similar to calcitriol. Do not use medications containing calcitriol while using vitamin D.
