A recent piece of research has suggested that there should be a reassessment of using calcium supplements to treat osteoporosis.
The study, which was published in the British Medical Journal, claimed that there could be a link between the use of the supplements and an increased risk of having a heart attack.
However, an independent nutritionist and spokesperson for the Health Supplements Information Service said that this risk is "relatively small".
Dr Carrie Ruxton noted: "Only 15 per cent of the subjects studied had heart-health status.
"That means that the majority didn't have any data on their heart health, so we don't know how the calcium supplements affected them at all."
She added that people should not change their habits if they are already taking the supplement because calcium is "essential to the diet".
According to the Journal of the American Medical Association, the coronary artery calcium score of a person can be used to predict their likelihood of their getting heart disease.
However, the extent to which this improves the classification of risk is unclear in comparison to traditional heart disease factors.
