Calcium supplements come in various forms, each offering different benefits and body absorption rates. When choosing a calcium tablet, one should consider the type and formulation that suits their health needs. The main forms include:
Calcium carbonate
Calcium carbonate is a common supplement because it is cheap and has a high calcium content. It is best taken with food because its absorption is enhanced by stomach acids. It can help those who are calcium deficient and those at risk of brittle bone disease.
Calcium citrate
Calcium citrate is easily absorbed even without food. It suits the elderly and those with low stomach acid who need calcium supplement tablets for osteoporosis. It is more expensive than carbonate but suitable for those with specific needs.
Calcium gluconate
Calcium gluconate is for those with low calcium levels or on a heart medication called digitalis. It is less concentrated than other forms and often used in hospitals. It is gentle on the stomach and suits people who cannot tolerate stronger forms.
Calcium lactate
Calcium lactate is another non-irritating supplement. It has lower calcium content but is gentle on the stomach. It is good for those who are sensitive to other forms of calcium. The body can easily absorb this non-irritating supplement.
Coral calcium
Coral calcium comes from fossilized coral reefs and claims to provide both calcium and trace minerals. It is less scientifically supported than other forms and could harm the environment. Those wanting a natural source may choose this.
Calcium is crucial for health, so supplement tablets are widely used across industries for prevention, treatment, and health maintenance. Below are the key applications of calcium supplements in the industrial context:
Healthcare and pharmaceuticals
Healthcare and pharmaceuticals use calcium supplements to treat osteoporosis, brittle bone disease. It helps in bone health and bone cancer treatments that weaken bones. Calcium supplements are used to prevent hypocalcemia, a deficiency disease. Hospitals use injectable forms like calcium gluconate for quick absorption in emergencies. This is especially so in patients with low calcium levels or taking heart medication digitalis.
Dairy and food industry
Calcium supplements are used to fortify milk substitutes like soy and almond milk. This helps in bone health and is a marketing point. Calcium lactate and gluconate are used to prevent food spoilage because they inhibit bacterial growth. This helps to extend shelf life.
Animal feed and livestock management
Calcium supplements are used in animal feed to ensure strong bones and good egg production in chickens. It treats calcium deficiencies in pets and livestock. It is especially for dogs and cats.
Construction and manufacturing
Calcium supplements are used in construction. Calcium carbonate is used to produce cement and concrete structures that are strong and last long. It is also used in the glass and steel industries. It helps in de-slagging and refining and purifying iron and steel.
Environmental applications
Calcium supplements are also used for water treatment. Calcium hydroxide is used to purify drinking water and remove impurities and harmful particles. It is also used in soil treatment. Calcium helps to restore acidic soils for better crop yields and reduced deforestation.
Check the ingredients list
Look for calcium carbonate or citrate in calcium tablet supplements. They are better absorbed. Avoid those with calcium gluconate or lactate as they have less calcium. Look for extra nutrients that improve bone health like vitamin D or magnesium.
Ensure it is third-party tested
As calcium supplements are often misused, reputable manufacturers have their products tested by independent laboratories for purity. Check if the manufacturer uses good manufacturing practices to reduce contamination and ensure consistent product quality.
Consider the form
Calcium supplement tablets are available in various forms. These include chewable, soft gels, or slow-release tablets. Each has its own pros and cons. For instance, chewable calcium supplements may contain added sugars or artificial flavors. This is unsuitable for diabetics or those watching their sugar intake. Slow-release tablets will be effective for a longer period and reduce the chances of side effects.
Store calcium supplements correctly
Exposure to moisture reduces the quality of calcium supplements. This is because it causes them to clump together or lose potency. Manufacturers normally recommend storing supplements in dry, cool places. This is to avoid contact with air, light, or heat.
Side effects
Calcium supplements may cause constipation, nausea, or gas. This is especially if taken in excess or without food. Hence start with a low dose and gradually increase it. Always take the tablets with food and plenty of water. Seek medical advice before using calcium supplements if there is a history of kidney stones, hypercalcemia, or heart disease.
