Who needs the best calcium supplement for women?

Studies say that calcium supplement for pregnant women protects against low-birthweight in newborns and lowers blood pressure in your kids thus helping to prevent hypertension in the next generation.

Though you may obtain calcium from natural sources, it would be beneficial if you supplement it during the second and third trimester of your pregnancy and lactation.

What is Calcium?

Calcium is found plentiful in your body. 99 percent of this mineral is used to sustain your skeletal structures and function. It also plays a pivotal role in cell signaling, muscle contraction, blood clotting and nerve function. Your cells use calcium to activate specific enzymes, receive and send neurotransmitters during communication with other cells and transport ions across the cellular membrane

It is one of the key players in maintaining a regular heartbeat. Studies say that calcium along with vitamin D may protect against cancer, high blood pressure, and diabetes.

Not all the calcium consumed is absorbed in your gut. You can absorb only 30% of calcium from foods. But the absorption rate varies depending upon the food consumed. If you consume too much calcium, the efficiency of its absorption decreases.

The total calcium absorption is high as 60% in infants and young children. The rate of absorption decreases to 15-20% in adulthood and continues to decline as we age. Phytic acid and oxalic acid which is naturally present in some plants can bind to it and inhibit its absorption.

Foods that are rich in oxalic acid include collard greens, spinach, sweet potatoes, beans, and rhubarb. Foods that contain high amounts of the phytic acid include beans, seeds, nuts, whole grain products, soy isolates and wheat bran. Vitamin D which you can obtain from food or produced by your skin when exposed to sunlight increases calcium absorption.

Some absorbed calcium gets eliminated from your body through urine, feces, and sweat. This amount gets affected due to sodium and protein intakes, alcohol intake, caffeine intake, phosphorous and fruits and vegetable intake.

During pregnancy, it is advisable to include the best calcium supplement for women. Common calcium supplement is labeled as follows

  • Calcium carbonate (40 percent elemental calcium)
  • Calcium gluconate (9 percent elemental calcium)
  • Calcium citrate (21 percent elemental calcium)
  • Calcium lactate (13 percent elemental calcium)

The primary forms of the calcium supplement for women are citrate and carbonate. The other forms of include gluconate and lactate. Some supplemental forms may also contain magnesium or Vitamin D. You must check the ingredient list to see the type of calcium present and what other nutrients it may provide.

Calcium carbonate is more commonly available and is inexpensive and convenient. It depends on stomach acid for absorption. So gets efficiently absorbed when you take it along with food. But you can take calcium citrate with or without food. It works best for people with inflammatory bowel disease, achlorhydria, and absorption disorders.

You can find the elemental calcium listed in the supplement facts panel. The percentage you can absorb from the best calcium supplement for women depends upon the total amount of elemental calcium that you consume at a time. Your body absorbs highest amounts of calcium in ≤500 mg doses. If you’re taking 1000mg of supplement, divide it into two 500mg and take it at different times during the day.

If you’re pregnant, then calcium supplementation during pregnancy reduces your risk of preeclampsia. It is a severe medical condition in which a pregnant woman develops hypertension and proteinuria after 20 weeks of gestation. This situation is the leading cause of maternal morbidity and mortality. It affects around 14% of pregnancies worldwide.

Inadequate intakes of calcium, over an extended period, might cause osteopenia (a condition in which your protein and mineral content of bone gets reduced). If left untreated it can lead to osteoporosis. It also increases the bone fracture risk, especially in adults. Calcium deficiency may also cause rickets. The calcium deficiency disease is called as hypocalcemia.

The causes include inadequate calcium intake during childhood, medications that decrease calcium absorption, hormonal changes especially in women, dietary intolerance to foods rich in calcium and specific genetic factors. Pancreatitis, renal failure, septic shock, massive blood transfusions, hungry bone syndrome, hyperphosphatemia and hypermagnesemia and hypomagnesemia can also cause hypocalcemia.

The symptoms of hypocalcemia include confusion or memory loss, numbness, and tingling in the hands, feet, and face, muscle spasms, hallucinations, depression, muscle cramps, weak and brittle nails, slower hair growth, fragile thin skin and bones that are vulnerable to fractures. Calcium plays a vital role in both in muscle contractions and neurotransmitter release. So it can cause seizures in otherwise healthy people.

What are the Benefits of Calcium Supplements for Pregnant Women?

The WHO recommends calcium supplementation for women from the 20th week, until the end of pregnancy especially for those who have a high risk of gestational hypertension. On an average, your fetus demands 30g of calcium by the end of gestation: 50mg per day during the second trimester and 250mg/day during the third quarter.

Reduces risk of preeclampsia

Preeclampsia is characterized by high blood pressure. If you don’t treat this condition, it can result in eclampsia. Eclampsia may cause convulsions and seizures, dangerous to you and your baby. If you develop preeclampsia during pregnancy, it can cause preterm birth. If you have an adequate supply of calcium, then you can reduce the risk of preterm delivery.

Fewer PMS symptoms

A study published by the National Institute of Mental Health found women who took 120mg of calcium per day, reduced most of their PMS symptoms by 50%. This mineral reduces PMS symptoms like dizziness, mood swings, hypertension and much more. Low levels of calcium trigger the release of hormones that are responsible for mood swings, including depression and irritability.

Bone health

Pregnancy can be an excellent time for bone health because you’re able to absorb more calcium. Your body creates bone strengthening estrogen which facilities the absorption of calcium. And your overall skeleton gets strength training, thanks to the weight of your baby.

Weight management

If there is a deficiency in calcium, the body will release parathyroid hormone. This hormone will stimulate your bones, to release calcium into your bloodstream which maintains the balance. Parathyroid hormone can also stimulate fat production and prevents its breakdown. So right amounts of calcium are essential to prevent obesity.

Protects cardiac muscles

Adequate amounts of calcium help cardiac muscles to relax and contract properly. It encourages your nervous system to maintain proper pressure in your arteries.

Prevents colon cancer

Calcium in sufficient amounts reduces your risk of colon cancer. It also suppresses the growth of polyps that lead to cancer. Proper supplementation reduces the risk of adenomas and nonmalignant tumors of the colon. The excess mineral on its way through the colon binds with cancer promoters, and together they are excreted from your body.

Prevents kidney stones

Getting too little calcium in your diet could make your oxalate levels to shoot up and cause kidney stones. So make sure to take the recommended level of this mineral. Try to obtain your RDA mainly from foods, since some studies link calcium supplements to kidney stones.

Controls alkaline pH levels

Excess sugar, junk foods, and preserved foods contribute to the formation of acidity in your body. It gives rise to various diseases like cancer, hypertension, and kidney stones. Calcium aids to maintain a healthy pH level thereby enhances your vitality and overall health.

Dental care

This mineral keeps your jawbone sturdy throughout life. This action results in tightfitting teeth where bacteria cannot thrive. To ensure problem-free gums and teeth, include adequate calcium in your diet.

Protects against osteoporosis

Supplementation of calcium has been one of the standard treatment methods, to prevent and decrease osteoporosis for decades. Osteoporosis is a disease most common in postmenopausal women. It results in weak, fragile bones overtime due to bone deterioration and loss of bone mineral and mass. Calcium along with vitamin K, protein, and vitamin D helps reduce your risk of bone-related problems.

Lowers blood pressure

Supplemental dietary calcium helps to reduce high blood pressure. Diets restricted in this mineral increase blood pressure. In research studies, participants have experienced a significant decrease in systolic blood pressure after taking the calcium supplements.

Experts believe that best calcium supplements for women may alter your blood pressure by changing the metabolism of other electrolytes. It also plays a part in blood vessel activity and muscle strength, which is a massive plus during pregnancy.

What are the Points to Consider While Choosing a Calcium Supplement for Women?

While selecting the best calcium supplement, try to read the nutrition label. You must look at the amount of elemental calcium, not the milligrams or grams of calcium that’s written. These supplements cause a few side effects such as constipation, bloating and gas. Calcium carbonate is the most constipating. You can try a few different brands to find the one that you tolerate best.

Some of the calcium supplements for women can interact with bisphosphonates, blood pressure medications, synthetic thyroid hormones, antibiotics and calcium channel blockers. Along with supplements, if you eat calcium-fortified foods, you may be ingesting more of this mineral than you realize. Check your supplement and food labels, to see how much total calcium you’re getting a day.
