Most of it exists as calcium salts in our bones. This calcium can be reduced to soluble calcium if we aren't getting enough calcium through diet, and this would reduce the density and tensile strength of the bones. read more

The calcium in the body fluids can exist in three forms: (1) as the free cation Ca 2+ (about 50% of the calcium in the fluids), (2) bound to proteins (about 40% of the calcium in the fluids), and (3) complexed with other ions (about 10% of the calcium in the fluids). read more

4. Calcium Gluconate. A form of of calcium with very low levels of actual calcium concentration. You would need to take very large amounts of the supplement to reach calcium requirements, and the bioavailability is still not certain. 5. Calcium Lactate. The form of calcium found in foods such as aged cheese and baking powder. read more
