Best 11 Benefits of Calcium Citrate

Calcium is one of the most essential minerals in our body; this element makes up roughly 2% of an adult’s body weight. It is needed to build and maintain teeth, bones, and cartilage and promotes the health of the nervous and cardiovascular systems.

Calcium citrate is a weaker form of calcium, providing roughly 20% calcium per pill. However, since they do not require stomach acid to be dissolved, they can be taken on an empty stomach, and they are more easily absorbed than pure calcium. Calcium citrate is particularly helpful for older individuals who may have less hydrochloric acid.

Calcium deficiencies are more common than you might think. A deficiency in calcium can lead to osteoporosis or osteopenia, and can cause symptoms such as fainting, muscle weakness, psoriasis, brittle nails, tooth decay, seizures, itching, problems swallowing, and numbness in the fingers and toes.

Calcium supplements can help tremendously in improving bone strength and preventing arthritis. Additionally, many calcium supplements include other nutrients such as magnesium and vitamin D, which can provide even more benefits. Below are several benefits of taking regular calcium supplements:

1. Promotes weight loss

Calcium is important in maintaining a healthy weight, and in some cases can even promote fat loss. A calcium deficiency can lead to increased production of the parathyroid hormone, also known as the “starvation” hormone. This hormone stimulates the production and accumulation of fat, as it signals to the body that it is starving. While this is important for surviving under extreme conditions, it will hinder your weight loss progress and mess up the hormonal balance of your body. A diet with the proper amount of calcium will promote fat loss through using it as fuel for the body.

2. Supports cardiovascular health

Calcium plays an important role in ensuring the heart expands and contracts properly, as well as maintains healthy pressure in the arteries. It also regulates the electrical charges needed to keep the heart beating. A calcium deficiency can lead to artificial measures being implemented to increase blood pressure within the coronary vessels.

3. Reduces the risk of colon cancer

Adequate levels of calcium is correlated with low rates of malignant polyps in the colon. Science suggests that excess calcium is able to inactivate carcinogenic compounds in the waste, thus preventing the growth of cancerous cells. Calcium is also known as a chelating agent, as it binds and neutralizes many toxins.

4. Prevents kidney stones

Though kidney stones are made of calcium, it is calcium oxalate, not the calcium we ingest as supplements. Taking supplements that contain calcium gluconate or calcium carbonate can help break down and excrete kidney stones and even prevent their formation in the first place.

5. Balance pH levels

The pH scale refers to the acidity or alkalinity of bodily fluids. Blood needs to be slightly alkaline, whereas stomach acid is, naturally, very acidic. Overall, however, the body should be slightly alkaline. Sometimes, however, the body becomes too acidic; examples of this include heartburn and indigestion. Calcium helps normalize the pH levels in all bodily fluids.

6. Transports other nutrients

Calcium often acts as a drawbridge. Sometimes certain nutrients are unable to cross over into cells, but calcium channels enable those nutrients to penetrate the necessary cells.

7. Alleviates PMS symptoms

Every woman dreads her monthly cycle, and PMS symptoms can make this time even worse. Thankfully, calcium, when interacting with natural hormones found in the body, can help minimize negative side effects such as mood swings.

8. May reduce the risk of type 2 diabetes

The correlation is yet officially confirmed, but large-scale studies have found that individuals who take regular calcium supplements face a lesser risk of developing type 2 diabetes as compared to those who took no supplements.

9. Promotes skeletal growth in fetuses

Pregnant women must increase their intake of all nutrients, not just calcium. The developing fetus needs extra nutrients to develop properly, and if an expectant mother does not increase her nutrient consumption, the fetus may experience abnormal growth. Increased calcium will help the baby’s bones grow properly as well as strengthen the mother’s bones.

10. Prevents osteoporosis

Osteoporosis, found most commonly in post-menopausal women, is a condition in when the bones become brittle and more prone to breakage. By increasing their intake of calcium, older women can stave off or even entirely prevent the onset of osteoporosis.

11. Promotes dental health

A calcium deficiency can cause the teeth to soften, resulting in deterioration of enamel and more cavities. Gums can also become more sensitive and prone to bleeding if proper amounts of calcium are not ingested. By ensuring you consume an adequate amount of calcium, you promote good dental health and hygiene.
