2021's 10 Best Calcium Carbonate
TOP SUPPLEMENTS

Best Calcium Carbonate

Calcium is the most abundant mineral in the human body and is essential for optimal health. The majority of calcium is found in the bones and teeth, but every cell in the body needs calcium to function. It acts as a cofactor in many enzymatic reactions and is required for muscle contraction. (See Reference 1)

Calcium carbonate is a powerful and affordable supplemental form, offering the highest amount of elemental calcium among supplements – 40% pure calcium by weight! (See Reference 2)

Dietary Sources of Calcium

Some of the best dietary sources of calcium include:

  • Dairy products
  • Fish
  • Green leafy vegetables
  • Broccoli
  • Nuts and seeds
  • Fortified juices and cereals

Risks Factors for Low Calcium

Many conditions and lifestyle factors may cause low calcium levels. A calcium carbonate supplement may be beneficial if you:

  • Experience frequent bone fractures
  • Have tooth decay
  • Are vegan
  • Eat a high-protein diet
  • Are a menopausal woman
  • Have low vitamin D levels
  • Frequently consume coffee and alcohol
  • Suffer from a chronic digestive condition
  • Have used laxatives long-term

Calcium Carbonate Benefits

Strong Bones and Teeth

99% of the body’s calcium is found in the bones and teeth, where it’s involved in maintaining the strength of these tissues. Children and teenagers have a high demand for calcium as their teeth and bones are still growing and developing. (See Reference 3)

A 2014 study on military personnel found that taking 2000mg of calcium – alongside vitamin D – for 9 weeks:

  • Increased circulating calcium levels
  • Maintained bone strength during intense activity

Fractures and Bone Loss in the Elderly

Calcium is important for older people as bone density declines with age – the rate of bone loss begins exceeding the rate of bone formation. Menopausal and post-menopausal women are especially at risk for weak bones and fractures due to low levels of the bone-protective hormone estrogen. (See Reference 4)

A 2017 report on the role of calcium in musculoskeletal aging concluded that calcium supplementation leads to reduced fracture risk in elderly people – when used with vitamin D.

It’s important to note that calcium supplementation improves bone density best when used in conjunction with vitamin D, weight-bearing exercise and a healthy diet.

PMS Symptoms

Interesting research suggests calcium supplements may help women to manage the unpleasant symptoms of premenstrual syndrome (PMS). (See Reference 6)

Studies show that women with PMS who supplement with 500-1000mg of calcium see the following benefits:

  • Reductions in anxiety and mood swings
  • Decreased feelings of fatigue
  • Reduced bloating and water retention
  • Improvements in pain (See Reference 7)

Heart Health

The link between calcium and heart health is controversial, with some studies finding hypercalcemia (high calcium levels) associated with cardiovascular disease.

However, you need healthy levels of calcium to regulate blood pressure by relaxing the smooth muscle in blood vessels.

Effects of Dieting

Optimizing calcium with calcium carbonate supports your metabolism and may enhance your weight loss efforts. (See Reference 5)

A study looked at overweight students who consumed a calorie-restricted diet for three months, either alone or along with 600mg elemental calcium. The results found those who took the calcium supplements lost significantly more fat mass – including visceral fat.

Calcium Carbonate Considerations

Calcium carbonate is a safe natural supplement. However, when increasing calcium levels, you must also optimize levels of vitamin D, vitamin K and magnesium. These nutrients work in synergy with calcium to ensure its absorption.
