Oral Calcium Supplements

Jun 14, 2025

Calcium is a vital nutrient essential for healthy and strong bones. Experts agree that the best way to get the nutrients required to remain healthy is from food naturally. At APD Pharmaceutical Manufacturing Pte Ltd, we understand that even though a diet is an ideal option to obtain the calcium your body needs, it may fall short at times. We manufacture and supply oral calcium supplements to meet the nutrient needs of consumers. If you are planning to launch a calcium supplement brand or expand your existing business, partner with us, the leading nutritional dietary supplement manufacturer in Singapore. Before collaborating with us, here’s all you need to know about dietary calcium supplements and their impact on overall health and well-being.

Understanding the Risk of Too Little Calcium

A deficiency of calcium in the body may result in several health problems relating to weak bones. The lack of this nutrient may prevent children from reaching their full potential in terms of height. On the other hand, adults may experience low bone mass, increasing the risk of osteoporosis.

A majority of people fail to get the required amount of calcium from their diet. Children and adolescents are particularly at risk of calcium deficiency. Adults who are of the age 50 years and above may also experience a lack of this nutrient.

Effectiveness and Uses of Calcium

Everybody requires calcium to maintain and enhance bone health. The muscles, nerves, and heart also need it for effective functioning. Besides these, the uses of calcium are vast. Here’s the list of health conditions for which calcium proves to be effective!

  • Indigestion: Calcium carbonate serves as an antacid and helps treat indigestion issues.
  • Kidney Failure: Consuming calcium acetate or calcium carbonate by mouth is effective in controlling the high levels of phosphate in the blood of individuals suffering from kidney failure. This nutrient also aids in lowering the blood pressure of kidney patients.
  • Hypocalcemia: Individuals with low calcium levels in the blood can greatly benefit from the intake of calcium by mouth.
  • Hyperkalemia: Calcium gluconate aids in reversing heart issues caused due to high levels of potassium.
  • Hyperparathyroidism: The intake of calcium by mouth helps lower the levels of parathyroid hormone in people suffering from kidney failure.
  • Premenstrual Syndrome (PMS): Adequate amounts of calcium can significantly reduce pain, mood swings, food cravings, and bloating among women experiencing premenstrual syndrome.
  • Osteoporosis: Consuming the required amount of calcium aids in effectively treating osteoporosis and preventing bone loss.
  • Osteomalacia: Taking calcium is likely to reverse the condition of softening of bones caused due to very little intake of the nutrient.
  • Bone Strength in Unborn Babies: Consuming oral calcium supplements during pregnancy enhances the bone mineral density of the unborn baby.
  • Pre-eclampsia: Taking calcium has the potential to minimize the risk of pregnancy complications due to high blood pressure.
  • Tooth Retention: Consuming calcium along with vitamin D prevents tooth loss among older people.
  • Colon or Rectal Cancer: Taking oral calcium supplements is possibly effective in lowering the risk of colorectal cancer. 

Calcium Requirements

Knowing the amount of calcium individuals need, depending on age and sex, is crucial. Here’s the information you must know!

For Men

Age Recommended Amount of Calcium
19-50 years 1,000 mg
51-70 years 1,000 mg
71 years and older 1,200 mg

For Women

Age Recommended Amount of Calcium
19-50 years 1,000 mg
51 years and older 1,200 mg

The advisable upper limit of calcium per day is 2,500 mg for individuals who are between the ages of 19 to 50 years. For older adults who are of the age 51 years and above, the recommended limit of calcium per day is 2,000 mg.

An Overview of Calcium and Diet

Our body doesn’t produce calcium. Therefore, obtaining it from different sources is vital. The various food items that can provide you with calcium include:

  • Dark green leafy vegetables like kale and broccoli
  • Dairy products like milk, yogurt, and cheese
  • Calcium fortified foods like cereals and soy products, and beverages such as milk substitutes and fruit juices
  • Fish having edible soft bones, like canned salmon and sardines.

For effective absorption of calcium, your body will require vitamin D. Certain food items contain a small amount of vitamin D, like egg yolk and canned salmon with bones.

Who Can Benefit from Calcium Supplements?

Even if a person is consuming a healthy and balanced diet, getting enough calcium can be difficult. The oral calcium supplements are ideal for individuals who:

  • Consume limited dairy products or are lactose intolerant
  • Have digestive or bowel issues like celiac disease or inflammatory bowel disease that can lower the ability to absorb calcium
  • Are on a vegan diet
  • Are under long-term treatment and consume corticosteroids
  • Intake a large amount of sodium or protein, causing the body to excrete a greater amount of calcium.

In all of the above conditions, the calcium supplements help meet the nutrient requirements of the individuals. Before deciding on the consumption of the supplements, taking the recommendations of a dietitian or healthcare professional is a wise decision.

Precautions When Taking Calcium Supplements

Calcium supplements aren’t ideal for everyone. For instance, individuals with health conditions like hypercalcemia, which leads to excess calcium in the bloodstream, must avoid the intake of calcium supplements. Other precautions that the consumers must take include:

  • Determining whether they are allergic to any calcium supplement or the ingredients present in it.
  • Discussing with the healthcare professionals if they are already consuming other supplements, herbal medicines, or traditional medications.
  • Ensuring a gap of at least two hours between the consumption of the calcium supplements and antibiotics or iron supplements.
  • Taking the oral calcium supplements just as prescribed by the healthcare professionals.
  • Avoiding the consumption of calcium above the recommended daily limit.
  • Placing the supplements in a dry and cool place, away from direct sunlight. 

Tips for Choosing Oral Calcium Supplements

At APD Pharmaceutical Manufacturing Pte Ltd, we are committed to delivering the best value to the supplement brands and end-users. Here are some quick tips to ensure you select the top-quality oral calcium supplements.

Consider the Calcium Amount

Elemental calcium matters as it is the actual amount of the nutrient present in the supplement. Checking the label of the supplement can provide you with insights into the amount of calcium present in one serving. Make sure to take a note of the serving size or the number of calcium tablets while determining how much calcium is present.

Factor in the Interaction with Medications

The calcium supplements may interact with different medications like antibiotics, calcium channel blockers, synthetic thyroid hormones, blood pressure medications, and bisphosphonates.  So, it is advisable to take the recommendation of the healthcare professionals and select supplements that the individuals can consume along with other medications.

Evaluate the Supplement Form

Calcium supplements are available in a wide range of forms, including capsules, tablets, powders, chews, and liquids. The calcium tablets for bone health are suitable for young children and adolescents. The liquid calcium supplements for adults are ideal for individuals having trouble swallowing.

Consider the Quality and Cost

As a leading manufacturer of oral calcium supplements, we supply the best quality supplements to various brands. We ensure meeting the standards set by the industry in terms of purity, quality, potency, dissolution, and tablet disintegration. With us, you can be rest assured of genuine products at competitive prices.

Check the Tolerability

Calcium supplements may have certain side effects, like constipation, bloating, and gas. Trying out different types of calcium supplements will make it easier to determine the one with the best tolerability. This factor will differ from person to person.

Understand the Absorbability

For the oral calcium supplements to be effective, they must be completely absorbed by the body. The absorbability of the supplements usually increases when they are consumed in small doses, like 500 mg or less, during meal time.
