Stroke: Calcium and Vitamin D Supplements Together May Increase Stroke Risk by 17%

A study by American scientists, published in the journal Annals of Internal Medicine in 2019, found a link between certain types of pills that combine vitamin D and calcium with stroke. Researchers think the combination could cause atherosclerosis, a disease that occurs when fatty substances build up in the arteries. If left untreated, it can block blood flow to the heart or brain, eventually leading to strokes or heart attacks.

Dr. Safi Khan, who led the study at West Virginia University, explained: “A combination of calcium and vitamin D was associated with a higher risk of stroke.

“Other supplements appeared to have no significant effect on mortality or cardiovascular outcomes.”

As part of the study, the team reviewed 277 randomized controlled trials involving nearly one million people.

The effect of 16 different supplements and eight different diets on mortality and the heart was analysed.

It found that cutting back on salt and eating omega-3 fatty acids — such as fatty fish — helped prevent heart disease. And it concluded that folic acid could protect against stroke.

However, it showed that supplements consisting of vitamin D and calcium increased the risk of stroke by 17 percent.

The study said: “Calcium plus vitamin D increased stroke risk. Other dietary supplements, such as vitamin B6, vitamin A, multivitamins, antioxidants, and iron and dietary interventions, such as reduced fat intake, had no significant effect on mortality or cardiovascular disease.” .”

Supplements that combine calcium with vitamin D are usually taken to promote bone health – by older people who are at higher risk of stroke.
