Calcium Citrate Powder

Calcium Citrate comes in the form of a vaguely tart salt-like compound made up of Citric Acid and Calcium. It is used as an additive in food to impart that tart flavor into various dishes, aside from its main usage as a supplement with health benefits. It can also be used as a preservative and a way to soften water.

Calcium Citrate and Calcium Carbonate both contain Calcium, but while Calcium Carbonate may be the most popularly used form of Calcium supplement, this does not make it accessible to everyone. Calcium Citrate is a perfect alternative to Calcium Carbonate for those that have weak or sensitive stomachs, or other gastrointestinal disorders since the Calcium Carbonate is more likely to cause stomach upset when used. Calcium Citrate may even be fully digested by people that have a gastric acid deficiency in their bodies.

Because Calcium is found the most throughout the human body of any other mineral, it is absolutely essential to maintain high levels of Calcium in order for the body to function properly. Osteoporosis, or as it is sometimes called, 'brittle bone syndrome', is caused when there is a Calcium deficiency in the body. Whenever levels of Calcium have hit a low, Calcium will actually be extracted from the bones to redistribute throughout the body in an attempt to level out. Processes such as blood clotting and nerve impulse transmission need to be fueled by Calcium in order to operate properly. On top of that Calcium is also important for the purposes of maintaining strong bones and teeth as well as muscle contraction. Calcium can also be useful in the binding and neutralization of generally harmful molecules in the body.

One of the largest sources of Calcium is in dairy, with just one small serving of dairy containing about 300mg, or one-fourth of the total daily value for Calcium. However, Calcium is also found in many other natural sources such as seaweed, nuts, legumes, and quinoa. Despite its wide distribution throughout the food pyramid, some people still suffer from Hypocalcemia (or Vitamin D deficiency) which causes issues with Calcium absorption. This is because Calcium can only be correctly absorbed by the body with the help of Vitamin D. A good Calcium-rich diet or supplement routine should still include appropriate levels of Vitamin D in it for this reason.

Serving Size & Timing

Natural foods will always be the best source of Calcium, but as far as this supplement is concerned, it is best to take about 2400mg of Calcium Citrate at a time, once or twice per day. Because this compound is made up of 21% Calcium, having a 2400mg serving size will result in an overall amount of 500mg of pure Calcium being consumed per serving, which is about half of the FDA-recommended daily value of 1000mg. These values are slightly adjusted for age and certain conditions. For example, it is recommended that infants have about 600mg per day, children under four should take 800mg and women who are pregnant (especially those who are nursing) should take 1300mg per day.

If you are already taking antacids that contain Calcium or any other kind of medication with Calcium, a physician should first be consulted before use. Excess intake could eventually decrease its effectiveness and dilute stomach acid, causing it to improperly dissolve these medications. If you have had kidney stones in the past, parathyroid disease or take any other antacids or Calcium supplements, you should discuss this product with your doctor before beginning a course.


There are no fillers in this solution of Calcium Citrate. It is vegan friendly and should be stored in a dry, dark and cool area.


There are no harmful side effects to consider when taking Calcium Citrate supplements unless overdose occurs. Those that go beyond the recommended daily value up to 2.5 grams could cause an imbalance in bodily mineral storage. Minor side effects which may result from overdose could include irregular heartbeat, headaches, stomach upset and increased frequency of urination.


Calcium Citrate has a high bioavailability, and it is recommended that it be taken with Vitamin D supplements or in Vitamin D-rich juices, since this will increase its effectiveness and maximize its absorption. Calcium Citrate does not dissolve well in water, but when taken with a cold citrus juice like orange juice or lemonade, its solubility will increase significantly.

One of the largest sources of Calcium is in dairy, with just one small serving of dairy containing about 300mg, or 1/4 of the total daily value for Calcium. However, Calcium is also found in many other natural sources such as seaweed, nuts, legumes and quinoa.
