Flawed Calcium and Heart Attack Study Misleads Consumers

August 11th, 2010 No comments

On July 29, 2010, the British Medical Journal published a flawed study of the usage of calcium supplements and associated risk of heart attack. The study misleadingly concluded that use of calcium supplements increases the risk of heart attacks by 27% and has no significant effect on overall mortality.

Some in the media are broadcasting this study as a reason to stop using calcium supplements.

In particular, the study examined the impact of a combination of exercise and vitamins C and E on insulin sensitivity and other parameters of diabetic illness and as well as endogenous (body-produced) antioxidant defenses include superoxide dismutase (SOD) and glutathione peroxidase.
