Key Factors. Here are key factors that can affect how well your body is able to absorb the calcium you take in. A diet high in phytic acid — Found in the bran coating of whole grains, phytic acid binds calcium and other minerals, making them insoluble and not absorbable in the intestines. Your calcium then passes out of the body without being absorbed.
