Could someone correct this? 25 in and 10+5 out doesn't give a net 5 in, so one of the numbers has to be wrong. —The preceding unsigned comment was added by Cnyh (talk • contribs) 10:17, 27 March 2007 (UTC).
Agree with post by Cnyh. Numbers don't add up. Found a new source that states "The percentage of calcium absorbed depends on the total amount of elemental calcium consumed at one time; as the amount increases, the percentage absorption decreases. Absorption is highest in doses ≤ 500 mg. So, for example, one who takes 1,000 mg/day of calcium from supplements might split the dose and take 500 mg at two separate times during the day."— Preceding unsigned comment added by 22.214.171.124 (talk) 12:49, 7 June 2012 (UTC)
