Can calcium supplements cause blood clots? Here’s what the experts say – Times of India

Recent research suggests that high levels of calcium supplements it can increase the risk of heart problems. Cardiologists recommend getting calcium from food rather than supplements for better health outcomes. However calcium essential for bone and heart health, it is best obtained from food sources. Calcium enters the muscle cells of your heart during each heartbeat. This helps regulate your heart rhythm.
Other studies have linked calcium supplements to cardiovascular problems such as heart attacks and blood vessel damage. A 2016 study by the Journal of the American Heart Association involving more than 5,000 adults found that those who got the most calcium in their diet had a lower risk of heart problems. However, those taking the supplements showed more signs of heart damage. Other studies, including one in 2020, have noted increased numbers in people using supplements. Calcification is associated with hardening of the arteries or “hardening of the arteries”. Although the consensus on the specific risks is not agreed, more and more researchers are finding a potential risk. A 2020 review of 42 studies and a 2021 review of 15 studies suggest that calcium supplements may harm the heart. When supplements are taken, calcium levels in the blood rise, which can damage the arteries and lead to calcification. It is possible that supplements may increase the risk of heart problems.
Dr. Parneesh Arora, Senior Director, Interventional Cardiology, Cardiac Sciences, Max Super Specialty Hospital Patparganj, says “Calcium supplements can be a double-edged sword. It should be used with caution. To measure the value of calcium in serum, to explore alternatives to calcium deficiency like osteoporosis and above all doctors advise that they be followed.”

Plaque accumulation

Calcium supplements can increase the risk of plaque buildup in the arteries, which can lead to heart failure. Plaque is a buildup of calcium, fat, and other substances that can clog and harden blood vessels and interfere with heart valves.

Increased risk of myocardial infarction and stroke

Some studies have found that calcium supplements increase the risk of myocardial infarction and stroke.

Hypercalcemia

If you have a health condition that causes too much calcium in your blood (hypercalcemia), you should avoid calcium supplements

Both men and women need calcium for bone health, but women are more likely to take supplements, which can lead to greater risk. People with chronic kidney disease or those with kidney disease should be very careful. It is advisable to consult a healthcare professional before starting any supplement, as they can help assess the need and potential risks.

Dr. Shuvanan Ray, Director, Cardiology, Fortis Hospital, Anandapur says, “Calcium supplements do not directly cause calcium to build up in the arteries. Coronary artery calcium is a symptom of atherosclerosis, which is hardening and narrowing of blood vessels due to the formation of plaque.
“Especially in severe cases of atherosclerosis, such as chronic kidney disease (CKD) or coronary artery disease (CAD), the deposition of calcium in the arteries is more prominent. But this calcium accumulates due to the disease itself and not with external calcium supplements,” he adds.

What other factors can block blood vessels?

Several risk factors can contribute to blocked arteries, including:
Genetics
High cholesterol
Hypertension (high blood pressure)
Smoking
Diabetes
Are There Any Supplements Or Risks To Heart Health?
It is important to avoid high-fat and high-calorie foods, which can negatively affect heart health. Non-steroidal anti-inflammatory drugs (NSAIDs), which are often used as painkillers, can also put heart health at risk.
For many, food is still the best source of calcium. Ensuring a healthy diet can prevent heart disease without the risks associated with supplements.
