Calcium supplements are very popular among the dietary supplements category. Millions of people take calcium supplements in an effort to stave off osteoporosis. If we take a look of statistics, ten million Americans and three million people in UK suffer with osteoporosis. Majority of them rely on calcium supplements. A recent study brings the fact that calcium supplement intake may increase the risk of heart diseases.
About the study
Researchers from New Zealand, the United Kingdom and the United States examined 11 studies of more than 12,000 elderly people over four years. Half of the patients were given calcium supplements and the other half received placebo or dummy pills with no therapeutic content. The results showed that people who took supplements were 30% more likely to have a heart attack. Researcher further clarified that “If you have 1,000 people taking calcium for five years, we will expect to find 14 more heart attacks, 10 more strokes and 13 more deaths in the people given calcium than they would have had if they hadn’t been treated with calcium.”
The study was published in the British Medical Journal.
Calcium in natural state
Researchers supported natural intake of calcium as they found that those who had a diet naturally high in calcium were at no increased danger. In my understanding many people consider calcium pills as a natural remedy however, it calcium body. The Food Standards Agency recommends adults have 700mg of calcium a day from milk, cheese and green, leafy vegetables.
The National Osteoporosis Society said most people should be...
able to get enough calcium through their diets, rather than reaching for the medicine cabinet.
Calcium pills vs Heart attack
Although the reason for the increased risk of heart attack is not clear, but it is thought that the extra calcium circulating in the blood could lead to a hardening of the arteries. Calcium deposition in the arteries leads to the formation of plaques in blood vessels, which can cause heart attack, stroke and other cardiovascular diseases. Researcher further added that this condition doesn’t arise when people get calcium from their diet because the calcium from food is absorbed slowly, so the blood calcium level does not change.
As people age, bone breakdown gradually may occur more than bone buildup, leading to weak bones and increased risk of fracture. If you are taking calcium pill for your healthy bones and also suffering with heart disease, you should take advice with your doctor before taking calcium supplements.
