Regularly taking joint supplements may lower the risk of heart disease and stroke, research suggests.
A new study published in the British Medical Journal (BMJ) found that glucosamine, which is commonly taken by people with joint pain or suffering from arthritis, could have a role in protecting the heart.
Experts, including those from the Harvard School of Public Health in the US, looked at data for 466,039 British men and women who completed questionnaires on what supplements they took.
Death certificates and hospital records were then used to track deaths from heart disease, as well as heart disease problems and stroke for an average of seven years.
Overall, almost one in five (19.3 percent) people recorded taking glucosamine at the start of the study.
The researchers found that glucosamine use was associated with a 9 percent to 22 percent lower risk of coronary heart disease, stroke, and death from coronary heart disease compared with people who did not take the supplement.
