Some facts about calcium supplements

Your gut can not absorb all the calcium you take, you can absorb 30% of calcium from foods at best. Also, the rate of calcium absorption depends on the type of foods you consume. However, the rate of calcium absorption decreases if you consume too much calcium.

In infants and children, the rate of absorption is much higher and it is around 60% in them. On the other hand, the efficiency of absorption usually decreases with older age. However, there are some plants which contain phytic (beans, seeds, nuts, soy etc.) and oxalic acid (spinach, sweet potatoes, beans etc.) which interrupt the rate of absorption. On the other hand, vitamin D, which you can get from sunlight exposure or from food source, will increase the rate of calcium absorption by your body.

Moreover, some particular food may eliminate absorbed calcium from your body. These include sodium, protein, alcohol, caffeine, some vegetables and some fruits.

However, it is important to include the best calcium tablets for women during pregnancy. There are several common calcium supplements which are as follows:

  • Calcium carbonate (40 % elemental calcium) (Widely available, inexpensive and suitable. The rate of absorption increases if you take with food)
  • Calcium gluconate (9 % elemental calcium)
  • Calcium citrate (21 % elemental calcium) (you can take with or without food)
  • Calcium lactate (13 % elemental calcium)

Citrate and carbonate are the primary forms of calcium supplement. Also, there are also some supplements that contain magnesium or vitamin D. So, you need to check the list of ingredients choose the best suited for you.

How much calcium do you need?

Women ages 19 to 50: Women of this age range require 1,000 milligrams (mg)of calcium  per day before, during, and after pregnancy

Women age 18 and younger: Women of this particular age range require 1,300 mg of calcium per day before, during, and after pregnancy

However, it is a matter of concern that most American women don’t get nearly enough of this important mineral. It is required to take around 3 cups of dairy products or other calcium-rich foods every day.

Also, it is important to observe your calcium intake even after the birth of your baby and you are finished with breastfeeding, because you need this mineral to prevent osteoporosis in later life.

Food sources of calcium

Basically, milk and other dairy products are the best source of calcium. Also, canned fish, juice, cereals fortified with calcium, rice beverages, bread and soy are also good sources of this mineral. Also check the list of iron rich foods for pregnancy.

Should you take a calcium supplement?

You are getting at least 150 mg of calcium if you are taking a prenatal vitamin according to your doctor’s advice. Other than that, you can also try to take an individual or separate calcium supplement if you are not getting the right amount of calcium from your dietary source. However, you need to keep one thing in your mind that, your body can not absorb more than 500 mg of calcium at one time. Therefore, your doctor may suggest you to take calcium supplements in smaller doses for several times in a day.

Moreover, keep in mind that, you require vitamin D to absorb calcium, so make sure that you are getting sufficient amount of vitamin D in your pregnancy diet. However, I have already said that supplemental forms of calcium are commonly available in calcium carbonate and calcium citrate form.

It is more preferable and efficient way to take calcium carbonate (provides the most calcium, but extra stomach acid is required to facilitate dissolving it) with your meal to maximize the absorption.

On the other hand, calcium citrate does not require stomach acid for absorption, so it can be easily absorbed by your body. So, it can be taken in between you meal.

When to start taking calcium tablets during pregnancy

Although you should take calcium tablets according to your doctor’s advice, but you need to check the level to find whether it contains sufficient calcium, will dissolve well or not, and is free of lead and other toxic metal compounds.

Besides these, keep in mind that, avoid taking or buying calcium supplements containing dolomite, bone meal, coral or oyster shell, because these may contain a little amount of lead, that can be harmful for your baby in your womb.

Advantages of calcium supplements for women during pregnancy

According to the World Health Organization (WHO), calcium supplementation is necessary for the pregnant women (especially in the women with a higher risk of gestational hypertension) from the 20th week until the end of their pregnancy. However, your fetus requires 30 mg of calcium by the end of gestation, 50 mg  a day during the second trimester and 250 mg a day during the third trimester (an average value).

However, the advantages of calcium tablets during pregnancy are as follows:

  1. Minimize the risk of preeclampsia: Preeclampsia is a common phenomenon in pregnant women and is characterized by high blood pressure (HBP). Also, the situation may become worse if you do not take treatment for this condition, and it may result in eclampsia. Eclampsia can be dangerous to both you and your baby and it may cause seizures and convulsions. Moreover, preterm birth may also occur if you develop preeclampsia. So, if you get a sufficient supply of calcium, you are less likely to develop preeclampsia.
  2. Reduce PMS symptoms: PMS symptoms include dizziness, hypertension, mood swings etc. Low levels of calcium trigger the secretion of hormones that are responsible for mood swings such as depression. However, researches have shown that, the PMS symptoms can be reduced to 50% by taking around 120 mg of calcium per day.
  3. Weight control: Low levels of calcium also trigger the release of parathyroid hormone which may augment the production of it fats and its catabolism. So, it is required to take calcium supplements if necessary.
  4. Healthy bones: Although it is very common, but it is the most significant importance of calcium. If you do not get enough calcium, your bones will become weak. Pregnancy is a peak time to make your bone stronger, because your body can absorb more calcium during that time. However, getting enough calcium will help you to get strong teeth all the time, and it will also prevent you from osteoporosis in later life.
  5. Smooth functioning: Getting adequate amount of calcium will stimulate the nervous system to maintain the right blood pressure in arteries and it also helps the cardiac muscle to contract and relax properly.
  6. Prevent kidney stones: Low level of calcium can also cause kidney stones. So, it is important to get sufficient amount of calcium.

Probable side effects of calcium tablets

  1. Taking calcium supplements can make you feel bloated. Also, constipation is a common problem, because calcium carbonate decreases the frequency of bowel movement.
  2. I have already said that, if the calcium supplement contains a small amount of lead, it will create problem to the fetus.
  3. Although, a sufficient amount of calcium is required to prevent kidney stones, but high level of calcium may develop kidney stones. Also, it can interrupt the absorption of zinc and iron from food into the bloodstream.

Things to remember

Try to limit the calcium intake to the recommended dose.

Try to take calcium supplements with the foods that contain vitamin D, because vitamin D facilitates the absorption of calcium by your body.

Too much calcium during pregnancy
