10% calcium gluconate solution (given intravenously) is the form of calcium most widely used in the treatment of low blood calcium.This form of calcium is not as well absorbed as calcium lactate, [12] and it only contains 0.93% (93 mg/dL) calcium ion (defined by 1 g weight solute in 100 mL of solution to make 1% solution w/v).
Calcium formate seems to be safe as a calcium supplement for people with one time doses of 3.9 g (1200 of calcium) per day. [6] Increases in blood formate concentration have been observed with such doses, but in healthy subjects the formate does not accumulate, and is quickly metabolized.
Persons consuming more than 10 grams/day of calcium carbonate (4 grams of elemental calcium) are at risk of developing milk-alkali syndrome, [19] but the condition has been reported in at least one person consuming only 2.5 grams/day of calcium carbonate (1 gram of elemental calcium), an amount usually considered moderate and safe.
Calcium lactate is a well-absorbed and generally safe form of calcium supplementation [24] that does not interfere with digestion. [16] Its properties allow it to be used effectively without disrupting normal gastrointestinal function, making it suitable for individuals seeking to increase their calcium intake without affecting their digestive ...
A broad reference range of 20 to 150 nmol/L (8-60 ng/mL) has also been suggested, [16] while other studies have defined levels below 80 nmol/L (32 ng/mL) as indicative of vitamin D deficiency. [ 17 ] Increasing calcifediol levels up to levels of 80 nmol/L (32 ng/mL) are associated with increasing the fraction of calcium that is absorbed from ...
The US Institute of Medicine (IOM) established Recommended Dietary Allowances (RDAs) for calcium in 1997 and updated those values in 2011. [6] See table. The European Food Safety Authority (EFSA) uses the term Population Reference Intake (PRIs) instead of RDAs and sets slightly different numbers: ages 4–10 800 mg, ages 11–17 1150 mg, ages 18–24 1000 mg, and >25 years 950 mg.

The DRI was introduced in 1997 in order to broaden the existing system of RDAs. DRIs were published over the period 1998 to 2001. In 2011, revised DRIs were published for calcium and vitamin D. [7] Additionally, revised DRIs were published for potassium and sodium in 2019. [8] The DRI for energy was updated in 2023.
Calcium citrate is the calcium salt of citric acid. It is commonly used as a food additive , usually as a preservative, but sometimes for flavor. In this sense, it is similar to sodium citrate. Calcium citrate is also found in some dietary calcium supplements (e.g. Citracal or Caltrate). Calcium makes up 24.1% of calcium citrate (anhydrous) and ...
