The presence of Phytate and Oxalate in most natural-occurring calcium foods sources makes it nearly impossible to meet the Recommended Dietary Allowance (RDA) to maintain and build strong bone mass. People who have Lactose Intolerance (the inability to digest milk after ingesting it which can lead to abdominal pain and discomfort) also find it difficult to meet their daily calcium RDA needs.
The question is, how do we make up for this requirement (1000mg/day) ?? The answer CALCIUM SUPPLEMENTs comes quickly as lightening. As your Nutritionist, permit me to shake tables a little??
