Calcium is a vital mineral that helps keep our bones and teeth strong and supports muscle function, nerve signals, and blood clotting. From childhood through old age, calcium is essential for bone growth and maintenance, and it helps prevent bone diseases like osteoporosis. Many people, however, find it difficult to get enough calcium from their diet alone, leading them to consider calcium supplements. But is it better to get your calcium from food or supplements?
Healthy bones are an impossible dream without a balanced intake of vitamins, minerals, and other important nutrients. Obtaining that intake requires much effort, more than just drinking milk!
These foods help in building strong bones:
- Vitamin D: 10 to 15 minutes of sunlight exposure is the best source, apart from fish, dairy, and egg yolk.
- Vitamin K: Green leafy vegetables, broccoli, and peas.
- Vitamin B12: Sardines, eggs, dairy products.
- Calcium: Milk, yogurt, vegetables such as broccoli, cabbage, ragi, and soy.
- Magnesium: Green vegetables and nuts.
- Potassium: Bananas, orange juice, raisins, vegetables, and coconut water.
The Benefits of Calcium
Calcium plays several critical roles in the body, including:
- Bone Health: Calcium is a primary component of bones and teeth, making it essential for their strength and structure.
- Muscle Function: It helps muscles contract, including the heart muscle, ensuring proper cardiovascular function.
- Nerve Transmission: Calcium aids in transmitting messages through the nervous system.
- Blood Clotting: It plays a crucial role in blood clotting, helping wounds heal properly.
The Risks of Too Little Calcium
Inadequate calcium intake can lead to several health issues, such as:
- Osteoporosis: A condition where bones become weak and brittle, making them more prone to fractures.
- Hypocalcemia: Low levels of calcium in the blood can cause muscle cramps, spasms, and abnormal heart rhythms.
- Dental Issues: Insufficient calcium can result in weak teeth and an increased risk of cavities.
Daily Calcium Requirements
Ensuring you get the right amount of calcium is crucial for maintaining strong bones and overall health. Here's a detailed look at the recommended daily intake based on age and gender:
- Adults (19-50 years): Adults in this age range need 1,000 mg of calcium daily. This helps maintain bone density and supports muscle function, nerve transmission, and vascular contraction.
- Women over 50 and men over 70: As people age, calcium needs to increase to help counteract the natural loss of bone density. Women over 50 and men over 70 should aim for 1,200 mg of calcium daily to reduce the risk of osteoporosis and fractures.
- Children and adolescents: Growing bodies require more calcium to build strong bones. Children and teenagers need 1,300 mg per day to support rapid growth and development during these formative years.
Calcium and Diet
Meeting calcium needs through diet is often recommended for its added benefits, including other nutrients found in calcium-rich foods. Here are some excellent dietary sources of calcium:
- Dairy Products: Milk, cheese, and yogurt are rich in calcium and also provide protein and vitamin D.
- Leafy Greens: Kale, broccoli, and spinach offer calcium along with vitamins A and C.
- Fortified Foods: Many cereals, plant-based milks, and orange juice are fortified with calcium.
- Fish: Sardines and salmon with bones are excellent sources.
- Nuts and Seeds: Almonds and chia seeds are excellent sources of calcium.
Who Should Consider Calcium Supplements?
Calcium supplements may be necessary for individuals who struggle to meet their calcium needs through diet alone, such as:
- Postmenopausal Women: Due to decreased estrogen levels, which can lead to bone density loss.
- People with Lactose Intolerance or Dairy Allergy: Those who avoid dairy might need supplements.
- Vegans: Plant-based diets may lack sufficient calcium without fortified foods.
- Individuals with Certain Medical Conditions: Conditions like osteoporosis or certain gastrointestinal diseases can impair calcium absorption.

Do Calcium Supplements Have Risks?
While calcium supplements can help meet your daily needs, they come with potential risks, including:
- Kidney Stones: Excessive calcium from supplements can increase the risk of kidney stones.
- Cardiovascular Issues: Some studies suggest a possible link between high calcium supplement intake and heart disease.
- Gastrointestinal Problems: Calcium supplements can cause constipation or bloating in some individuals.
Types of Calcium Supplements
- Calcium Carbonate: Contains the highest amount of elemental calcium but requires stomach acid for absorption, best taken with food.
- Calcium Citrate: Easier to absorb and can be taken on an empty stomach, suitable for older adults and those with low stomach acid.
- Calcium Gluconate and Calcium Lactate: Contains less elemental calcium, requiring larger doses.
Choosing Calcium Supplements
When choosing a calcium supplement, keep these points in mind:
- Dosage: Ensure the supplement provides the appropriate amount of calcium needed.
- Absorption: Opt for a type that fits your digestive health and absorption ability.
- Added Nutrients: Some supplements include vitamin D or magnesium to enhance calcium absorption and bone health.
- Quality: Look for reputable brands with verified quality and safety standards.
Risk Of Having Too Much Calcium
Excessive calcium intake, whether from food or supplements, can pose health risks:
- Hypercalcemia: High blood calcium levels can lead to kidney dysfunction, impaired absorption of other minerals, and abnormal heart rhythms.
- Impaired Absorption of Other Minerals: Too much calcium can interfere with the absorption of zinc, iron, and magnesium.
Verdict: What's Better?
In most cases, obtaining calcium from a balanced diet is preferable. Foods rich in calcium not only provide the mineral but also essential nutrients crucial for overall health. However, supplements can be beneficial for those who struggle to meet daily requirements through diet alone, especially under specific circumstances like dietary restrictions or medical conditions. It's essential to consult with a healthcare provider to determine the right approach based on individual needs and health status. Remember, moderation and balance are key to maintaining optimal calcium levels and overall health.
